JTR Speakers?

[poutanen]

I just noticed your post. The phone number is 847 area code on the JTR website... north shore Chicago, right?... are you from JTR speakers?

He might be helpful with setup, rmk...

He *IS* JTR Speakers! lol

Ah, I see. I thought you said you were using Crown amps to power them, and figured you were using the Denon as a preamp. I can imagine a 4-ohm 600 watt IEC speaker would struggle when being powered by a ~150wpc amp, and vice versa, and that probably isn't good to base any judgement on.

I'm interested in your listening impressions once they are correctly powered and setup in your room.

I can't say for the JTR Triple 8's, but my mains (Yamaha S115V, 8 ohm, 98 SPL/1w, 500-1000W) sounded fine being powered by my receiver at 120w/ch, they sounded better being powered by a Behringer A500 at ~175w/ch, they sounded like completely different speakers when running a bridged Behringer A500 into each speaker at ~500w/ch.

I have a feeling these JTR's would be similar, they need to be powered enough to give them the headroom to sing...

Yeah, these are 4-ohm with a 600 watt IEC according to the website. Sensitive, but, you still would want to impedence match.

The T8's were each being powered by Pro Audio amps putting out 1000 WPC with a Denon 3806 as pre. I don't think insufficient power was the issue. My System is powered by a Sunfire 400/7 and it is rated at 800 WPC @4 Ohms so they will be getting a bit less power than they are used to on Sat.

Methinks power was not an issue...

K, I'm completely lost then. I'll just wait for your review, haha....

IMO, volume issue was due to the AVR driving them. It will be interesting to see how they sound vs the Revels.

...I interpret "driving them" as "powering them."

 

[poutanen]

The power was mostly pro audio (Crown amps) and a Denon 3806 AVR was the SSP. Like me, he had a dual display setup with an LCD flat panel and a nice Epson 1080 PJ and screen.

He uses Audyssey (via the Denon) and initially he had it engaged. With Audyssey engaged, the volume easily maxed out on the Denon.

Hold on, he was running 1000w/ch and the volume on the denon was maxed and it wasn't that loud? I think something may have needed a little tweaking with the setup!

FWIW, I run my main amps with the gain around half (past that you start getting noise), and the YPAO decided to bump my mains up 7-8 dB compared to the rest of the system. When I turn the volume up past 0 dB on the receiver, it's VERY loud, and the lights on the same circuit start dimming (I'm not joking).

Any idea what the gains on the crowns were set at? What about the pre-outs? I'm not familiar with those amps, but with a proper signal getting to them, and the JTRs, you should have been over 110 dB in there when pushing it. I think you'd find that loud!

It's too bad I couldn't get a set of JTR's to test drive in my house! lol

Sorry for the confusion. Audyssey on the Denon caused the volume issue but I believe that the amps and other system components were running off of a single 16amp circuit. I'm sure that contributed to the problem so I guess you could say that power was an issue. That should not be a problem in my Ht as I have 2-20's and one 16 amp dedicated circuits in the room.

Makes sense now, I'd like to hear how the JTR's are in your room (where all other things are equal)...

On another note, why does this Audyssey mute the volume so much? I thought it was similar to Yamahas YPAO, and the YPAO just tries to self setup for phase, distance, gain, and parametric-eq on each speaker. I've always got it "engaged" and the volumes aren't a problem. Is the denon a different kind of system?

I have never used nor heard YPAO so can't comment. Many Audyssey users (me included) have noted decreased SPL with Audyssey engaged. As it is cutting frequency peaks I suppose this is to be expected but I find that for me it over treats the sound and the results are dead sounding. Audyssey has both killed and over emphasized LFE in my system. I am beginning to think that the cheap little mic may be the culprit.

After running Audyssey EQ at least 25 times on my Integra 9.8 over the last few months and noting highly variable results, I now leave it off.

How did it go? Or are you testing this evening?

I assume this was for me?

I did hear the JTR Triple 12LF's at another Forum (AVS) members house yesterday. The T8's are being brought to my HT by their owner and that is this afternoon. I will post my impressions this evening or tomorrow morning. For a teaser, the T12's are amazing.

JTR Speakers

So as not to clog up Forums with redundant posts, here is a link to my informal demos of the JTR speakers this week.

 

[cbraver]

Very interesting.

It seems that these are an option for some of the bass heads on here that need mains to match the output of their subwoofers. They need to be put behind a screen though. Those things are so ugly. If your Revels are on par with them, please keep those, your theater is so nicely done those things would make it look like crap in my opinion. If you built a false wall and used an acoustically transparent screen, go for it.

They really don't look that bad.

Am I a "bass head"..well it is what it is.

You are actually onto my new "master plan" and it will actually be easier than you described it as the wall behind my mains and eqiuipment cabinet is an empty attic space. Everything in wall and a BIG AT screen with a light canon PJ. If I do this, it will be a measure twice (maybe three times), cut once project that would be upgradeitis proof.

Sure, that's what they all say

Good write up, good to see them compared back to back with another speaker in the same room with all else being equal.

Also, good to hear your comments RE: pro-audio vs. home. I was beginning to think I was out to lunch!

Now, if only we could get Jeff to make the T8's in piano black, I'd buy 5 of them!

p.s. Angel by Massive Attack is one of my fave test tracks too, such a good deep bass at the beginning, good vocals, solid guitars. Fun!

 

[cbraver]

Massive Attack "Angel" is a great test... I like "Teardrop" from them also, especially the Mad Professor Mazaruni Vocal Mix.

Yes, they do.

Then those might be a great solution!! I took a look at your home theater again, I had not seen it in a while, and didn't remember all the subs... You are a bass head! Consider demoing Bag End as well. A lot of films have been recorded using them as monitors, and they have speakers for just about every application that sound wonderful. I'm a big fan, and for a big room that is what I would recommend. Of course, I haven't heard JTR speakers so I can't compare the two.

What a great project you have in mind. Please keep me up to date on it if you decide to go that route. I love the clean front wall look.

If you're looking for more bass, I might sell my Yamaha SW118's (come on, everyone loves an 18" sub!) all you'd need is a yamaha P7000S and these things would pump! lol

I'll get ya quote

They could for sure work visibly with some wood veneer and a grill cloth. Easy to do after you have the speakers. I just wouldn't order them with Line-X unless your planning on touring with them.

It would be cool to buy the sub unfinished and then put some black marble on top. Lots of options.
