My Sister-in-Law took advantage of the holiday EMP deals and purchased a full 7.1 system from them including the new ES-1010i subwoofer E55Ti towers, E56CI center, E55WI surrounds and some RBH TK-615 in-celing speakers. I convinced her to get two 1010 subs b/c she is in a large open room and...

I have these speakers and use them with a Velodyne MiniVee sub for my computer system. People are amazed anytime they hear it. For a small room and a nearfield monitor to be used with a sub, I haven't heard better! $300 is a great deal provided you use them as noted by myself and others in...

I will inquire when the weather warms up this spring.

Aperion Audio is giving away a pair of their award winning Verus Grand Bookshelf Speakers ($598 MSRP) to one (1) lucky entrant! Perfect for use as front speakers in a small home theater or as surround speakers in a larger home entertainment center, the Verus Grand Bookshelf Speakers will bring...

Little can be discerned from those measurements. 98dB in room 1 foot away from the sub isn't particularly loud.

Agreed. I went to install my sister-in-law's LED display to her home theater yesterday and found that these TV's no longer come with RCA connectors on them. Instead they have a dongle that breaks out for component video. The dongle is so flimsy that if any tension is placed on it, it will...

b/c you are effectively making one big panel infinitely smaller by adding more bracing, thus raising the resonance frequency. The RBH method is overkill but its for a $50k pair of speakers so one would expect them to over design it. I've written about this before and here is an excerpt:

The point of this article was to show the modal effects of panels under various loading and bracing conditions using the industry's most sophisticated modeling tool (Finite Element Analysis) used by Structural Engineers which David Waratuke is. It makes no pretense on audibility, that wasn't...

Jim told me the crossover design was not his own and after I found this issue he said he was discontinuing the product. Perhaps he has a redesign now. I have no way of knowing. I tried to review 2 pairs of speakers from Salk and both pairs had issues and there is no room in my schedule at...

I apologize for not seeing "Salk" in the filename of that graph. I thought I deleted all references to brand in that measurement. I have just fixed the graph so it no longer shows a name. The speaker in question did in fact measure that way. I measured both speakers so it wasn't a simple...

Guys, as promised, we just published what is likely the most detailed look at cabinet bracing ever done by any publication or loudspeaker company for that matter. David Waratuke is a Structural Engineer that designs buildings for a living. He used Finite Element Analysis and heavy math to take...

Crap I replaced the trace with "Sweep" but didn't see it where the filename called it out. I will change out the image. It wasn't my intent to give Salk a black eye, especially since they no longer make that speaker. [edit] I fixed the image and my apologies to Salk.

I didn't want to mention names but the speaker in question is no longer in production after I took a look at it and found the impedance issue. I measured both speakers and they both measured the same so it was likely a design issue. The speakers sounded very good but they just couldn't play...

The Scan Speak 9500 has one of the lowest resonance frequencies I've seen in a tweeter (around 600Hz I believe) and yet nobody I know of uses a first order filter on it. But if that is B&W's claim then so be it. It's weird that I see no resistor pad down on their tweet in the schematic. I need...

It also needs to be conducted by a panel of listeners NOT without familiarity bias. The listeners should be able to repeat these listening sessions over a course of several days to see how their opinions change over time. Seriously how crazy do we really have to get with listening tests. Any...

Harman is right on the money with this! I don't buy into "we use 1st order networks or NO network at all to yield better phase response, or keep in the magic pixie dust to better preserve the fidelity :) That being said, you can use lower than 4th order networks if the drivers are robust...

Without seeing the schematic, the 1st example looks like 2nd order networks to me. Each driver has an LC element connected in the crossover though I may be mistaken. Some companies will claim to use 1st order networks but upon closer inspection they are often higher order or most complex...

Very true on all accounts! I proposed to EMP a business model like Build a Bear where you can customize your speaker by choosing a series of upgrade options in drivers, crossovers, etc. You then get a speaker with a birth certificate with measurements and a statement they were custom built...

I meant dull in the context of comparing a tonally neutral speaker to a bright one. I have heard many speakers over the years that have an elevated top end that at first listen appear to sound more revealing but overtime very fatiguing and unnatural sounding.

The bottom line is you have to spend a good amount of time with a speaker to ultimately determine if you like how it sounds. A bright/bassy speaker will initially sound better than a neutral speaker in short sighted or blind tests. Try living with a bright speaker over a course of a few...
