I spoke with Al at RAW Acoustics as well as Bob at CSS last week, they have a new ribbon called the RT2 which can be built into line arrays like my Omegas, all custom down to the binding posts and plate finish. My Omegas are 95db@1watt/1m, XBL mids with industry leading low distortion levels. The dynamics are crazy too, best I've ever heard. Of course you can't walk into a Best Buy and take them home but they are an incredible value for anyone wanting to experience ultra-high-end sound at a reasonable investment. I'll keep mine for decades, that is for sure smile.gif

Man that is a great looking set of speakers. Will there be issues with combing with a line array of midrange drivers? Do you have a in-room response plot to show us?

Good timing, I just ordered my MiniDSP Umik yesterday. By ear I don't sense any combing issues; these are by far the best speakers I have ever heard and they impress me every time I listen to them. Once the Umik arrives I'll get some response graphs posted to show everyone what they look like. Thanks!

So funny i just ordered the exact same mic myself yesterday!

What did those speakers run you? Im curious of those as an option for surround speakers in-wall custom made.

The line arrays? I'd reach out to Al at RAW, I bought them directly from Bob at CSS and now that they use the RT2 ribbon (less expensive but still based on a high-end Aurum Cantus ribbon) and a newer mid, pricing is quite different. PM me for his contact info if you want, he's a super nice guy with amazing build skills.

Hey Eyleron. Was wondering if you could add a speaker to the list to see how it stacks up? Its the Electro-Voice TS940D. One of my local theaters has them as stage speakers in two of there rooms and Ive been so impressed with them over the years watching countless movies on them. Its always a treat when I hear them. Here is some specs.

Specifications

Sound Pressure Level at 1 Meter,
1 Watt Input:
100 dB

Short-Term Peak:
1,200 watts
Crossover Frequency:
500 Hz
Recommended Crossover Frequency

section):

Crossover Slopes,
Recommended:
24 dB per octave
Minimum:

EVX-150A woofer; HMK-4 horn/drivermounting
bracket
Finishes:

mounting bracket, and black textured



Heres its spreadsheet link: http://www.rsem.com/pdf_manuals/electro-voice/ts940d.pdf

Heres a link where you can see a pic of them: http://www.rsem.com/equipment-details.asp?partnum=TS940D

These guys have always blew me away with there incredible midrange and dynamics. 2-channel preshow music is played thru them before the previews start and they always image so well. I had read an article by Tom Holman who use to judge cinema setups with stereo content to test imaging. Also from reading the specs Im a little confused on the crossover point from the CD to the low frequency drivers. Says 500hz but reccomends 1,150hz.
Thanks alot!

so how would the HSU HB1-MK2 compare in sensitivity to the Klipsch RF-62II. Does the HSU really have a sensitivity of 92 in the same way most speakers rate sensitivity? I am trying to decide between a Klipsch setup and the HSU. I currently have some ascend acoustics CMT-340 that show a 89db sensitivity anechoic that I m told is the same as the HSU because of them being meausred in half space which would drop the real sensitivity by 3db.

Klipsch has been known to over-rate their sensitivity badly. There is no way the RF-62 is 97 dB like they claim. 97 dB is more like pro-audio speakers. Klipsch are more sensitive than normal, but the only honest specs for their speakers are on the Heritage line and pro lines. No doubt the RF-62s are more powerful than the Hsu speakers though, but at least Hsu spec their speakers correctly. A lot of speaker manufacturers will spec their sensitivity to an 'in-room' rating without mentioning that fact, like 1/2 space, 1/4 space, or even 1/8 space. Hsu at least tells you how their speaker was rated.

Anyone use SLS Speakers? http://www.slsloudspeakers.com/SLS%20Audio%20Products.htm

 

Looks like stage, studio, cinema, home.

First, great effort on this thread. The challenge is that all of this data is flawed in one way or another. Second, its extremely challenging to model speaker behaviors on a spreadsheet.

There are speakers on this list that really exceed THX's and the SMPTE Standards, but if you are single factor weighting for high output, you will be disappointed.

I cannot say this enough, "Trust your ears."

Professional loudspeaker designers trust their ears, but they're just as emphatic as Mr.Reagan was in that they also verify, with measurements. Measuring tools have at least a hundred times the accuracy and resolution that the human ear does. The problem with manufacturer supplied specs is that very few show the single most important piece of data, a measured SPL response chart. In the absence of measured SPL charts manufacturer data should be considered unsubstantiated advertising copy.
