In Reply to: RE: anyone experienced with MCM's $24 compression driver ? posted by freddyi on January 18, 2017 at 10:14:46
I finally threw mine into the trash a couple of years ago. With 16 ohm impedance, it wasn't nominally efficient . I didn't have any horn that could go low enough to use its low Fs and it didn't go high enough on a circular waveguide or K-tube (maybe 2-3 KHz max). Also, my pair was mismatched from day 1 :)
thanks - the picture looks like China did a good job on the cosmetics - if not the mechanics of the thing. Partsexpress offers a phenolic driver with transformer with data on their 20" re-entrant horn - not sure if it would make it to 2K5 or not
Plot is terrible....falls bad way before 4K even. Stay away!.
If I needed low response, I'd stick with the Atlas one used on
