Dan Wiggins posted the results in this HTT thread , but I'll paste 'em here for anyone interested:
Whoa! I didn't realize that the Dharman was THIS good a performer? If I remember correctly, don't these performnace numbers equal or possible exceed the performance of the SVS 20-39cs sub tested by Tom N? If so, the Adire Dharman is an incredible deal... Under $600 for a powered sub that kicks butt! At least, this gives us consumers another top notch performing, inexpensive subwoofer, in another form factor, to choose from....
There was (is?) a thread on HTT that got a little nasty between TV, Mike Knapp and the guy from Adire. The Dharman was... mentioned

Nousaine numbers for Dharman
Average SPL 25-62 Hz: 107.9 dB
Average SPL 20-62 Hz: 105.9 dB
Bass Extension: 20 Hz @ 96 dB SPL
Maximum Output: 114.6 dB SPL @ 32 Hz
Here's the 10% THD limit SPLs Tom measured in his large 7500 cubic foot room:
20 Hz: 96 dB SPL
25 Hz: 102 dB SPL
32 Hz: 114.6 dB SPL (system at maximum)
40 Hz: 111.8 dB SPL (system at maximum)
50 Hz: 108.1 dB SPL
62 Hz: 103.1 dB SPL
Wow! That's stunning for a
good numbers,not unexpected from adire of course.
I'd caution against comparing them to the 20-39s numbers though. The 20-39 Nousaine measured was built and shipped to him almost a year and a half ago...the improvements weve made in the meantime have been extensive.Just like HSU has upgraded the 1201 driver to the 1202,and upgraded the driver and amp in the VTF-2 recently.
This would be like us comparing whatever subwoofer we're building in 2003 to the numbers TN just measured on the adire.
Along with the good SPL numbers,the adire freq-extension(response) was 49hz...the 1.5 year old 20-39cs was 25hz...a full octave lower...and the HSUs were both in the 30hz range if memory serves.
Didn't anybody click my link?
On that list, are the 20-39cs numbers from the T$S review, issue #86? I can't find a [email protected]%THD measurement in the review.
Jack, to make you feel better, I did click on that link. Took me a while to get through it...
Jerry, from the numbers above, if you're looking at the DUAL 20-39CS, then that package beats out the single lonely Dharman. But the numbers on the SINGLE Dharman looks better than the SINGLE 20-39CS to me.
Tom V, what would be the expected performance data for the current 20-39CS? Thanks.
My passion is 2 channel music. While certain numbers (such as flat frequency response) count, they provide very limited information as to how a product sounds. In fact, it is well known that equipment can measure well but sound lousy. While I realize that the needs of HT are somewhat different from those of stereo, I refuse to accept that this basic tenet doesn't hold for HT as well.
As such, I find it odd that published numbers would arouse such passion.
IMO, contrarly to most music and HT gear, a subwoofer the one component where measurements DO tell the whole story. It is a much less complex piece than say a speaker or a receiver.
Jack, you took the words right out of my mouth!
I entirely agree, the ones posted do not tell the whole story, but more data can (group delay etc...)
Holadem - I am tired of agreeing with ya!
Well then, I agree with you too
Hehe, I see Holadem and I are really on the same page, today.
Dan Wiggins of Adire has posted the group delay measurements for the Dharman (as measured by Adire, TN does not measure this) and explained the frequency response rolloff HERE for anyone interested.
For those that insisted on objective numbers on this product, there are now objective numbers. For those that want subjective opinions, there are subjective opinions galore....everyone should be placated now.
