Speaker driver measurements: 2-4" midrange, full range

[Zuhl]

Have you looked at the Morel EM1308? I have it working really well with an SEAS L18 and an SEAS 22TAF/G.

I think I remember reading somewhere that it is essentially just an MDM55 with a metal faceplate? If that is the case the price isn't justified. The MDM55 has been tested by zaph audio already and his data can be loosely correlated with my results.

All the peerless measured as expected. The TC5 are kind of interesting; Tweeter-like response at the top end but much different distortion characteristic at the bottom end since they are an overhung motor with much higher xmax and lower fs than the average tweeter. They overload more gradually than the average tweeter. Would work great in an array - I'm thinking of how I can use a pair of them with a 7" woofer.

Peerless 830970 and Aura NS3 are close to unlistenable imo.

The Tang band has an excellent motor, I just wish they found a better cone for it. I've always said that TB need to put a metal cone on one of their better motor designs. This motor with a metal cone would be killer.

The RS52F is a bit of an upset. The RS52A I purchased years ago performs much better.

Great resource of results!

Regarding the Tang Band drivers and metal cones...

Have you considered listening or testing W2 800SL or W3 1285SG?

In my humble opinion these are two great motors and cones!

Both of those drivers are no longer available aren't they? The W3-1285SG looks similar to the W3-1335SB except with a phase plug. It would be good to see a metal cone on a motor with more xmax like the motor from the W3-2141 or W3-1878.

The replacement for the W2-800SL, the W2-2243S looks worth a shot. The only 2" TB driver i've tested so far, the W2-748SG, I would have liked to see a little lower distortion from 700Hz-1kHz so I'd be hoping to find a driver which can improve on that.

Really impressed with the Dynavox LY302F - probably the best 'full range' driver I've tested to date. The MCM 55-5650 would also make a fine midrange - and I suspect it is a close relative of the Dayton RS100

What about HiVi dome midrange drivers like DMB-A?

 

[TMM]

Zaph tested the DMB-A; distortion is only average and the faceplate is enormous. Maybe the DMN-A might do better.

2nd and 3rd is higher than I would have liked, and THD will be relativly high as a result. (..while the higher harmonics are fantastic).

-anyway, nice addition to the group!

 

[akarma 76]

Zaph tested the DMB-A;

I can't find the test.

DAYTON AUDIO RS100P-8 looks good. Very smooth.

Thanks! Looks like good offer for 70bucks. Wanna try it in my future design. The real drawback for me is huge flange.

sica has this interesting 3,5"

..bumping this thread,

-because the website is a fantastic resource.

Hi Timothy,

I note the presence of the TC5FC07 on that list; did you ever get around to testing that one? I didn't see it on your current small mid measurement list.

Thanks!

Amazing work! May I ask couple of questions?
-Dynavox LY302F - does this speaker look like can survive real full-range work? You mentioned that construction decisions are questionable.

-Dayton RS75 - is this driver suitable for real full range duty including 10+ kHz? Sound is just a bit metallic or the signature is too much expressed? How it is in comparison to RS100?
