Klipschorn: corrected per a review

Others (e.g., a French magazine) have obtained a figure of about 98 dB when there was no corner. That may have been out in the middle of a room, or in an anechoic chamber (unspecified). I think the highly respected Heyser of Audio magazine also got 98, but then wrote that 1 watt probably would produce 104 (or 105) in a room corner -- an educated guess on his part?
I corrected with a note that the speaker is intended to be used in a room corner where one will get more efficiency in bass.

Added!

Consolidated and sorted marketing data focusing on high output speakers

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."
Thanks. And yup, it's a big challenge. Consider this more of a, "Consolidated and sorted marketing data focusing on high output speakers."

Completely different than, say, data-bass.com with its measured data on subwoofer performance.

As always, a prospective consumer should look up trusted reviews, get input from real owners, and try to audition the speakers, in theirs or someone's equivalent space, if possible.

The utility of this spreadsheet is in presenting the marketing data, adjusted where possible, such that their spaces are being compared to eachother. And you can discount speakers that even the lying bastards in the marketing department don't claim good output.

For instance, if Paradigm's Series 7 Center 3 was advertised as only having 90dB anechoic sensitivity, and 93dB in-room, and able to handle 175w program, we can figure...
  • 100w from a typical receiver would only get you 102dB
  • That 100w is about 2/3rd of its own program watts rating
  • The 212w it'd take to reach 105dB from 12ft is above what its published rating will allow. You're right, that's probably thermal. It's much worse in terms of distortion.
  • The higher SPLs, if they can even be generated, are probably full of distortion.

So this is not a high output speaker, as pitched by their marketing department. If you want to listen at -5 or have a large space, this is not the speaker for you.

Danley Sound Labs: Jericho J3

Added the Jericho J3.

Low frequency: 6 x 15"
Mid frequency: 8 x 6"
High frequency: 4 x 1.4"

Specs aren't complete, so I extrapolated based on the 4200w program for the low frequency, which is supposed to be 153dB, and I assume outdoors at 1m. Subtract 3dB for 4ohm.



Hope that helps someone towards their...outdoor theater dreams?

2 Pro Audio Tech added and Surrounds

Quote:

But there should be more of them, I agree.
I've added the SCR-15sm. This will get you 115dB from 12' away without dipping into peak watts. This would be reference level without straining/distortion.
  • 92dB sensitivity (LF)
  • 1 x 15" woofer
  • 3" compression driver on large constant directivity horn
  • Requires own active amp, 1400w LF / 220w HF
  • Price?

Selfishly, since I am looking for some in-wall surrounds speakers to go with SEOS fronts, I'll find some surrounds to add to the list.

I've added the SCRS-26im in-wall. This will get you 109dB from 12' using 560w program power. Less than half that will get you reference level with less distortion, which is fantastic for in-wall surround speakers.
  • 90dB sensitivity (LF)
  • 2 x 6" woofers
  • 1" compression driver on elliptical constant directivity horn
  • Fits in 2 x 4 stud bay
  • Requires active amp, 560w LF / 120W HF
  • Price?

Tough to find surrounds that can keep up
Does anyone have some good suggestions for other surround speakers >= 94dB sensitivity?

I was looking at those that fit in a 3.5" stud cavity, but that depth restriction is sure limiting. I have a narrow room, but in the rennovation I was able to move a load-bearing wall a few inches and am now at 12' wide. I think I can get away with a little bump-out of a column of a couple inches. This would maybe enable some of the diy speakers that need 5-6" depth.

SLS Audio: Cinema System 50 ribbon

SLS Audio specializes in pro ribbon speakers.
The Cinema System 50 (CS12) is for smaller cinemas, typically used behind an acoustically transparent screen.
  • 12" woofer
  • 3 or 4" ribbon
  • 98dB sensitivity
  • 119dB from 12' when sending its 800w rated program watts
  • 34w will get you reference level from 12'

Reaction Audio Speakers

http://reaction-audio.myshopify.com/...ions/speakers/

Added three coaxial speakers from Reaction Audio, which I first heard about for their subwoofers.

These could be alternatives to Tannoy coaxial driver speakers, that image as a point-source due to no driver spacing between high and low frequency drivers.

The CX-8 is an 8", the CX-10 a 10", and the CX-15T a 15". Sensitivity in the low to mid-90's as they extend a little deeper (70, 70, and 35Hz respectively).

Sensitivity on the CX-15T's is rated 99dB and I can tell you that they are every bit as sensitive as my JTR 228HT's. And in room response is at least down to 30hz. We ran them full range at a little GTG that I hosted yesterday and anyone that was there will tell you how impressive they were running full range. No sub needed for music use that's for sure.

Vancouver GTG round 2.


reviews of the speakers are slowly trickling in. All of the speakers at the GTG would be considered high sensitivity & spl speakers.
I personally really liked the new CX-15T's and think I'll be going to those over my JTR 228HT's in my theater room.

Ah I see y'all already put it through the paces!

I think out of habit I assumed the sensitivity was in-room. If it's half-space then I'll keep as they've listed it. I've corrected the spreadsheet.

Thanks!

Oh, I'm definitely settled for a while . Does it get any better? Well, I don't know for sure. But if it does I definitely want those speakers, lol. The M2's set a very high standard, that's for sure.

Meyer Sound: Acheron 80

Meyer Sound is a big name in pro audio, furnishing installed sound, touring speakers, and cinema speakers. They're based out of California.
Here we have the Acheron 80, intended for small-to-medium theaters and screening rooms.
An active speaker, it has a huge 4" compression driver, huge horn, and a 15" woofer. Powered by its own 1685w program amp, active cooling, it'll yield 139dB peaks with distortion not exceeding .02% (program or peak watts?)

Here's an AVS thread discussing a few years ago

The JBL Eon 612 is an active powered, portable stage speaker. 57-20kHz, 126dB peaks. $450.
A good speaker in that Mackie, Electrovoice, etc. pro speaker range, but with a lot more output.

These here http://www.sourcespeaker.com/OD8211.html aren't bad, they can also be ordered with custom veneers.

They even make a sound bar that puts out 120db

Correct. I was suggesting that it be added to the list as it meets all the criteria as far as I can tell.

The EON seems to be a 97.5 dB sensitive speaker so yes, it belongs here too.

Surrounds- Dual stacked BFM W10's

Belongs here? There are a few speakers with sensitivity in the 80's on the list.

@Eyleron

FYI, my "unofficial" sources say the J3 runs about $25K per speaker. Not sure where the $1,250 figure came from.
