My Problem is Hiss from the Emotiva Amplifiers, The High Efficiency of the JTR is bringing out all the flaws of the amp straight through with the music. I can hear this at low and high passages during music play back. Its evidently audible even during movie play back.
hmm... I have seven of those monoblocks. They do perform a lot better with 6-8 ohm and the noise floor does climb as it dips to 4 ohm. Those speakers don't have any published measurements. Do you know how low the impedance gets with them? I can only imagine what an impedence bode would look like! :rolleyes:

Have you had the speakers for longer than the UPA-1s? In the past did the speaker exhibit the same properties with different amplification?

What you describe sounds like "syllabus" or "bright" as people describe it. It's basically high frequency distortion. When people talk does it seem the the letter S like in the words "sucks" sorta roll off with a SSSssss?

You know generally that's caused by the properties of a loudspeaker not the amp driving it. Though an underdriven loudspeaker or overloaded amp can exhibit this as well depending on xovers both in amp and passive in speaker.

About 80% of the time though if it's "syllabus" and high freq distortion and brightness with ear fatigue it's the bloody loudspeaker brother!

Generally compression coaxial tweeters are RAGGED on FR plots and ARE NOT A DECENT TWEETER IMHO. Show me one "high-end" design for real meaning a "real" pedigree loudspeaker design for home use that uses a coaxial driver that would be considered "modern" as a design from the last 15 or so years. You won't because they don't exist.... and you know why? Because coaxial tweet/mid drivers generally SUCK on the highend as transducers. A simple look at the spec sheet will reveal this with ALL OF THEM. Emminence, C&M or what ever that Italian outfit is called. ALL OF THEM... Simply FACTS...

You know what coaxial drivers are manufactured for most and in what application they are used? friggin PA speakers for musak etc in hotels and they are generally examples of the worst transducer design you'll ever see. The come with tiny 70V transformers on the frame/basket and are total GARBAGE. The same goes for a lot of the transducers used for guitar amps etc. from both outfits. Total garbage 1960-70s transducer designs. But hey they sound great to rockstars with damaged hearing right! So they must be good for home audio!!! DUH!!!

Owhh and as cheap drivers for doors in cars on massive OEM/ODM deals at about a dollar a piece! again... GARBAGE PRODUCT

PS sensitivity is a BS spec for home audio for the most part unless your a tard and use tube amps! hahah It's so funny to see people be concerned about it and let that spec make them decide the loudspeaker and then... because it doesn't sound right... LOL... they go and buy a 500 pound gorilla amp like an ATI3000 series to drive a 98dB speaker!!!

Emotiva amps have a gain of 32 and 28 is normal. This should just affect the volume gain structure and not performance as you think/perceive. I'm curious if the Seaton subs have a ground on the IEC. Also if the pre/pro/AVR does and also if the Seaton subs use the same wall socket/plug.

This could tell me a thing or two about the design of the Seaton and/or the pre/pro/AVR regarding it's design and ground plane. BTW are you single ended or balanced? I assume single ended...



Im using Balanced cabled purchased from Bule Jeans, I also tried it with RCA and the same issue does not make a diffrence.

The Emotiva amps were fine with the B&W Speakers. Its just with JTR the sound is so screechy and hiss is abnormal. I have also grounded the Cable Link with a Isolator purchased from the US. Causes me headaches after 1 hour of listening to the JTRs

The Seaton Subs dont have a Grounding plug to the Plate ampl. I simply took out one of the plate screws and grounded it by rolling the wire arround the screw head.

The Hum has gone from the Subs. The Processor Onkyo has a grounding terminal at the back but grounding this makes no audible diffrence to the sound. The hiss is there.

For you to hear that tells me your between the ages of 20 and 45. A LOT of people over that age have Presbycusis. This doesn't mean their hearing is "bad" it just means that they simply can't hear the HF distortion you hear with SSsss etc. Some of these guys actually review speakers too ehh!

And give a thumbs up to speakers like the ones giving you issues.

:rolleyes:

I still don't know anything about your converter/transport. When you used the same playback device you imputted it into the HK AVR via HDMI or tos/link slash SP/DIF? I'm curious why you needed a balanced to unbalanced cable? Does your transport only have balanced outs? That doesn't make sense... somebody has been talking into your ear with BS as to how to fix the problem. That balanced to single ended cable is stupid if the device has single ended outputs and I'm most certain it does.

I like bluejeans but if you ever need pro cable assemblies like XLR etc then checkout Redco.com

Now this is just personal opinion and nothing more. I just want to get that straight first before I get FLAMMED by the vendor and owners of said gear.

OK


Dude... it's the speakers... Can you still return them? If not they get rid of them/sell them off!

LOL

Second... the subs...

Do you realize you could have got Brian Dings "Direct Servo" subs in a CUSTOM Salk Signature Sound cabinet for just over HALF the price Seaton is asking!

You could have got two BETTER subs for about a 1/4 less total $$$ WITH a Salk cabinet!

No offense JTR and Seaton just opinion and perhaps even FACT.

PS don't feel bad OP you could have done worse and purchase something like Axiom!

You can't replace it due to xover and other factors like the front baffle cutout etc. The tweet can't be removed either because it's apart of the driver design.

Your best bet it to sell them off to an unsuspecting Presbycusis suffering 55+ baby boomer that prob will think they sound great!

LOL

I'm not sure how large your room is but if it's not to big I'd take a serious look at the Ascend Sierra Tower and Sierra Horizon Center.

Comparing the Sierra Tower to those JTRs at a GRAND A PIECE or MORE EXPENSIVE that the $1800 Dave is asking for the NrT version is like comparing the Benchmark DAC to one of Audio GDs DACs.

The difference of the design and quality of parts is SUBSTANTIAL and what's even more CRAZY...

Ascends' and Audio GD's products are CHEAPER!!!

You have three choices IMHO for a decent solid-state amp.

#1

AB International

#2

Amplifier Technologies Inc.

#3

Emotiva Audio Corporation/Jade Designs
That is, of course, simply wrong on fact.

There are many, many makers of just fine amps. For example, there's absolutely nothing wrong with Bryston, Anthem, Crown, McIntosh, etc. (Sure, some are more expensive than others. Whatever. Some of those, such as the Anthem PVA-series, can be had for reasonable money.)

Emotiva's not one of 'em. They're too cheap to pay for an OSHA-approved NRTL to certify their electrical safety. If an amp doesn't have a stamp of approval from an NRTL on the back, a smart person doesn't buy it.

And the budget price is no excuse. Sherwood Newcastle stickered their seven channel A-965 for just 1500 USD through local dealers, and Jeff Hipps, et al., weren't too cheap to get the proper safety certifications for it. (They also otherwise engineered it better than one typically finds in cheap amps, with one of the blackest noise floors of any amp I've ever heard. In the same league as Anthem Statement, Bryston, and McIntosh.

A cheap amp is very expensive if one has a house fire and the claims agent uses the fact that one had a high voltage/current device that lacked the appropriate NRTL safety certification in the home to deny one's insurance claim.

hmm... I have seven of those monoblocks. They do perform a lot better with 6-8 ohm and the noise floor does climb as it dips to 4 ohm.
That's of course not the issue. The issue is that the Emotivas, in addition to lacking the safety certifications that would make them suitable for use in a domestic dwelling, want people to think their amps "sound better." That's how they get the rabid fans they have, after all, by sounding noticeably different from other amps. So they jack up the gain, and to hell with the noise problems that creates. For most inefficient speakers, it doesn't hurt anything, though it does limit their market a bit.

What you describe sounds like "syllabus" or "bright" as people describe it. It's basically high frequency distortion. When people talk does it seem the the letter S like in the words "sucks" sorta roll off with a SSSssss?
I suspect it's more like hiss, even with nothing playing.

PS: it's "sibilance."

Generally compression coaxial tweeters are RAGGED on FR plots and ARE NOT A DECENT TWEETER IMHO.
Incorrect. It's the diaphragm (dome, ribbon, cone, planar, whatever) mounted on a 180-deg waveguide (a.k.a. a flat baffle) that is simply incapable of high-fidelity music reproduction under the vast majority of circumstances.

Show me one "high-end" design for real meaning a "real" pedigree loudspeaker design for home use that uses a coaxial driver that would be considered "modern" as a design from the last 15 or so years.
So as to not repeat myself, KEF Reference 201/2

You won't because they don't exist....
Oh, what was that above?

Just for good measure, here's another from a different maker: Gradient Revolution.

and you know why? Because coaxial tweet/mid drivers generally SUCK on the highend as transducers. A simple look at the spec sheet will reveal this with ALL OF THEM.
Please show me the spec sheet that shows a compression driver on a proper low-diffraction waveguide.

Here, for reference, is what a Chinese clone of the B&C DE250 can do, on a low diffraction 12" waveguide:


Note not just the exemplary on-axis performance, but the properly controlled directivity. You won't find that with some 180deg waveguide.

You know what coaxial drivers are manufactured for most and in what application they are used? friggin PA speakers for musak etc in hotels and they are generally examples of the worst transducer design you'll ever see.
Such speakers typically have tweeters on a post or a bridge, not high-quality BMS ring radiators (judging by your stridently ignorant comments, a superior device to anything you've yet heard) firing through the pole piece of a cones designed to control their directivity. The JTR design also minimizes midrange cone motion by using a large midrange cone - which also helps increase the ratio of direct sound to reflections, unlike some stupid dome or ribbon flushed into a 180deg waveguide that indiscriminately sprays all over the front hemisphere - and by crossing it over to helper woofers.

PS sensitivity is a BS spec for home audio for the most part unless your a tard and use tube amps!
That reads as if it were written by someone who has yet to hear actual high fidelity reproduction.

Dynamics matter in real music.

Thermal compression matters in real audio systems.

Energy efficiency matters to civilized people.

hahah It's so funny to see people be concerned about it and let that spec make them decide the loudspeaker and then... because it doesn't sound right... LOL... they go and buy a 500 pound gorilla amp like an ATI3000 series to drive a 98dB speaker!!!
Well, that is a bit silly, I'd agree. With a speaker in the mid 90's, there's not much reason to go beyond 100W/ch. Unless it's cheap and can be done without noise.

PSS did you know that an amplifier will have MORE NOISE at 1W driven than at say 60% load! DUH!!!!!!
Not if it's a good one.

OK TANNOY's designs...

SURE LOOKS LIKE MODERN TRANSDUCER DESIGN TO ME!

:rolleyes:

no comment

You really should've just stuck to that "no comment."

Of course it doesn't look modern. That's because it isn't, and you're not knowledgeable enough to know that it isn't.

Tannoy retired that design long ago. Their current designs feature an improved phase plug (the "Tulip" radial design, as opposed to the pictured "Pepperpot"), and many other functional enhancements compared to the old Gold.

And some Englishmen still think they have an empire
Again, someone who knew something would know that Tannoy (like KEF, Quad, etc.) are now Chinese...

Indeed. I did several times reading your screed.

Do you realize you could have got Brian Dings "Direct Servo" subs in a CUSTOM Salk Signature Sound cabinet for just over HALF the price Seaton is asking!
Seaton's sub is much better. That flake's servo system compromises something material (top-end bandwidth) for something useless (lower 2d order distortion).

Salk's cabinetry is gorgeous, though.

I'm not sure how large your room is but if it's not to big I'd take a serious look at the Ascend Sierra Tower and Sierra Horizon Center.
Are you seriously suggesting a non-matching front trio?

Whatever respect I had, now officially gone.

There are two ways to do front speakers:

(1) identical speakers, at identical heights, in identical orientations
(2) flawed

You know very well I wasn't talking about a compression tweet on it's own. I was talking about coaxial designs and that's why I mentioned Tanoy and cheap PA ceiling address drivers.

So you're suggesting Emotiva's products are not certified?

You think Bring Ding is a FLAKE?

Yes there are many great cost affective amps out there. I only mentioned the three to tier them according to price and market. I thought that obvious...

Sibilance I stand corrected and thanks for making me feel stupid.

Do you agree that in a coaxial design the midwoofer acting as a waveguide as it has excursion has an affect on the tweeter's Fs !?!

Every coaxial design I've ever tested exhibit this property and it's SIMPLY PHYSICS

PS so what if Tanoy is made is Asia the point I was making is it has a British history and the technology used even today is British

It's not so much the tweeter as it's the entire coaxial design and the tweeter is apart of this.

I adequately addressed that. To put it simply, you're all wet.

Modern coincident and Dual Concentric drivers are capable of much higher fidelity to source material in real rooms than any ribbon or dome on a 180deg waveguide, because their major flaws are in a region where the human ear is insensitive, and if done right they offer consistent midrange directivity.

By contrast, a tweeter on a 180deg waveguide will offer nothing but a "mushroom cloud" of excess energy at the bottom of the tweeter's passband, and thus poor fidelity to the source material.

So you're suggestion Emotiva's products are not certified?
I'm not "suggesting" anything. I'm outright saying it. Here's a random picture of someone's Emotiva amp, from a Google image search.

PLEASE POINT OUT THE STAMP FROM AN OSHA-APPROVED NRTL THAT I'M NOT SEEING.

That is, fine one of these stamps not the back of it.

"CE" is not the recognized mark of an NRTL. It's a meaningless self-certification. See here.

Yes, non-NRTL-approved products are allowed to be sold in most states. But an intelligent consumer will refrain from buying them in favor of products from companies that aren't too cheap to get proper safety certifications.

You think Bring Ding is a FLAKE?
Yes, Brian Ding is a feckless flake.

Not only is his servo design an answer to a question nobody asked (how do I reduce levels of 2d order deep bass distortion from perceptually irrelevant to...lower than that), but also it comes at the cost of compromised performance above 100Hz (important in a modern multisub system).

Mark Seaton's sub may use similar-quality drivers, but his amplifier is considerably better (much more powerful, considerably more efficient, and a good bit more flexible in terms of processing options), and he doesn't have the servo junk to muck up the top part of the sub's response.

But that's just misplaced design choices. Ding's a flake because he thinks "interconnects" affect the sound of his subwoofers. He's gone so far as to recommend trying different "high end" brands of wires to people who have expressed dissatisfaction with the way his subwoofers performed.

WOW I wasn't aware of Emotiva's lack of CSA or UL. I just stupidly assumed they were. Why won't they pay for testing? Any idea?

As for the coaxial designs I'm just speaking from personal experience and manufacturer Fs publications.

I've never read Brian say such things about hookup wire. I've heard/seen arguments regarding amp power.

Who can argue Seaton doesn't haven't a very nice plate-amp and DSP.

BUT

Can you explain what he's hearing and also why it wasn't the case with his B&Ws? Can you explain the grounding issues with the Seatons with both brands of receiver and separates using the same mains socket.

Don't digital amps dump a lot of noise? Is that plate-amp grounded?

BTW the Sierra Tower and Sierra Horizon use the same drivers across the board.

What is your opinion on Keele's CBT arrays?

PS I don't give a **** about timbre matching the LCRs as I'm going to have Keeley LR CBT and CLD Scanspeak HDS/W4-1337WD center.

Cost-cutting, I assume.

It makes me wonder where else corners were cut to make them down to their current prices.

Can't have that much experience, if your poster-child for the modern coax is a 1960s-era Tannoy Monitor Gold that has no parts in common with any modern Tannoy Dual Concentric, or any other modern coincident/concentric driver. :)

I've never read Brian say such things about hookup wire.
Go to AVS and search under his name for "Kimber PBJ." You'll find a thread where he makes such idiotic comments and I call him out on it.

Can you explain what he's hearing and also why it wasn't the case with his B&Ws?
It's obvious. The Emo amps have too much gain. Like most high-gain amps, they hiss a bit, because they faithfully amplify all of the hiss ahead of them in the signal chain in addition to having their own noise.

Since the OP's previous speakers were inefficient duds (B&W, right?), the noise wasn't at as high a level. But it was still there, just not perhaps objectionable at the listening position.

(As an aside, now that he has competent speakers, the OP can start turning his room back into a room, rather than a padded cell. All the padding that was needed to make speakers with poor midrange directivity control like B&W's listenable is just killing spaciousness with real speakers.)

Can you explain the grounding issues with the Seatons with both brands of receiver and separates using the same mains socket.
Ground loops that need to be fixed are often just a practical fact of life. The cable TV is often a culprit (glad we don't have it.) That's one reason I prefer to have all of my electronics on the same outlet, rather than having plate amps plugged in around the room.

Don't digital amps dump a lot of noise? Is that plate-amp grounded?
To the first, they can, yes. To the second, obviously yes. Otherwise it wouldn't work.

BTW the Sierra Tower and Sierra Horizon use the same drivers across the board.
I wouldn't know. I don't keep up with makers/marketers of uninteresting low-fidelity speakers.

What is your opinion on Keele's CBT arrays?
Theoretically they have merit. Very interesting concept. Very convincing measurements, though I'm not convinced that such broad horizontal directivity is a good thing. And of course Don Keele is one of the dean emeritii of modern high performance audio, so if he's throwing his name behind a concept smart people will look twice at it.

I have never heard one, however. I would like to. Rick Craig showed an especially interesting one at AKFest this weekend, that was half height. Might be short enough to have three up front, without making the TV too high.

PS I don't give a **** about timbre matching the LCRs as I'm going to have Keeley LR CBT and CLD Scanspeak HDS/W4-1337WD center.
That will sound like unmitigated crap together. Consider a high fidelity solution instead. Like three CBT's, or three identical speakers that will fit your intended space.

No connection whatsoever. I also don't use any of their products.

My subs all use Aurasound underhung neo-radial-motor (NRT) drivers that are IMO more advanced than those used by JTR or Seaton (or Rythmik or SVS or...basically everyone but Nathan Funk, who has used the Aura drivers and whose current bespoke driver seems to take a lot of lessons from the Aurasound drivers. Before you ask, yes Mr. Funk made the cabinets for my reference mains, but I'm otherwise unaffiliated.)

(Of course, one couldn't sell a sub at the prices they charge with these drivers. My three commercial subs with these drivers stickered at $3500 for the two with the 12"/3" coil woofer, and $5000 for the one with the 15"/4" coil woofer.)

I currently power my multisub system with an Electrovoice CPS 8.5 bridged to 4-channel, which I assume doesn't use the Pascal modules that Seaton's amp uses. It's made in Germany; Bosch apparent owns EV now. Perhaps it's related to Camco amps. I don't know.

Though I did manage to recently pick up an NOS pair of the JBL-for-Revel "SUB 1500" drivers, which I will likely make into a dual-opposed sub like the Submersive. I know, they're overhung, but still.)

Every commercial loudspeaker I've bought in the past dozen years or so has been a KEF, NHT, or Tannoy.

So no, no connection.

Also I'm curious why your user name resolves on the vBulletin DB to DS1121. Is that username an alias for another and how can you have an alias like that if your not admin or have admin access or have admin do that for you?
Sorry, I know nothing about computers except that I prefer Macs to not-a-Macs.

I've picked my username because the Citroën DS "Goddess" is the finest automobile ever conceived. A 1969 DS-21 Pallas was my first car (owned for about 15yrs now) and she will be my last car as well. When I bought her there were three known ones in my home state. Now I believe she stands alone.
