Hello All,
I am trying to form a short list of wide bandwidth 1" compression drivers with very good sound quality that have good high frequency extension as well as the ability to play comfortably sub-1,000Hz. I would like to know the value/perfomance leaders in the sub-$400 and sub-$800 categories.
TIA.

You're welcome.
You might be hard pressed to find a better sounding driver, even at the 10x price range you are looking in. Very elegant sounding little guy, for domestic use (probably a little small for big pro sound work).
Another nice one is the DIYSG DNA60. A little better sensitivity, smoother on some larger horns, better power handling.
You're welcome.

I think you mean the DNA-360:
Denovo Audio DNA-360 compression driver DIY Sound Group
Performance is very good, with low distortion for a CD.
The BMS 4550 has a unique ring radiator plastic diaphragm which allows a steep slope 800Hz crossover. Download the long datasheet for tech info and SPL curves. This is Tom Danley's favorite 1" CD.
Google BMS 4550 on the QSC (same as PRV W35-25-B WG waveguide).
TD15M + BMS 4550 + QSC waveguide = az's "Spendy-Wave" build | Audiokarma Home Audio Stereo Discussion Forums
I use the Faital HF108 which has a plastic dome plus a very short phase plug for smooth 1.3kHz - 18kHz in a medium size waveguide like the PRV W35-25-B WG, Dimensions: 10.1" H x 14.2" W x 5.5" D. This PRV waveguide is said to reach 1kHz with a steep slope crossover. Just $10 at Parts Express.
If you have the room and the money, look at the large JMLC-350 horns for 1kHz. Big is Beautiful.

Used TAD TD-2001
Also:
Fostex D1405 Compression Horn Driver
-though I should say that I personally wouldn't use any of those listed so far without a high-pass above 1 kHz (regardless of horn, and even in under domestic use). Instead I'd probably go with a custom diffraction horn adapter (1.4 to 1) and a larger format driver (1.4).

new DNA-360 seems to be scace but the B&C DE250 seemingly was its root: B&C DE250 and "clones" | Audiokarma Home Audio Stereo Discussion Forums
Regarding Peerless - Tymphany DFM-2535R00-08 1" Compression Horn Driver:
Looks interesting, could you post some distortion (third harmonic at 2.83V) measurements, please?You might be hard pressed to find a better sounding driver

Have you tried the 2544R00 from Peerless? PE says it's new. Looks like a good option with a larger 1.75" vcPeerless by Tymphany DFM-2535R00-08 1" Compression Horn Driver 2/4-Bolt 8 Ohm

Thanks!Attached is the distortion measurement of the DFM-2535R00-08 on 18Sound XT120 horn.
Attached is the distortion measurement of the DFM-2535R00-08 on 18Sound XT120 horn. The measurement was taken at 0.5m distance, but with the SPL adjusted to 104dB at 1m.
Hmmm, over 1% (albeit mainly second order) everywhere.
Moderate level of second harmonic is intrinsic to all compression drivers. No big deal.
Not "all", but yes most of them.
That is one distinguishing factor of the DNA-360. Lower distortion.
Below is an image of the DNA-360 in a SEOS-12 horn, for example.

I don't by it, DNA-360 nominal sensitivity is stated as 108 dB 1W/1m (Denovo Audio DNA-360 compression driver DIY Sound Group), and on this picture nominal level is 98 dB - of course distortion will be very low with this 0.1 W driving signal. Try with 1W driving signal.
Comparing distortion measurements from different people using different equipment at different times is a good way to get confused.
Here is one from Bill small syns that used the Peerless, lower level again but is comparable to the other graph.
As Bill has both and has tested both he can probably give a verdict that can be relied on.
