Tweeter No.3
 
Hi all,
Just curious if anyone had had a chance to use Tweeter No. 3 yet? It looks quite interesting to me, with the closest competition being Vifa DQ25 and BC25.

Biggest hurdle I see using this tweeter is the Fs at 1.5kHz. This may require some additional crossover parts to get a good roll-off. The Vifa tweeters also have Fs in the same area, but the peak is lower. I may do some modelling to see how easy these are to use with only a few crossover parts. I'd be aiming for a crossover around 2.2-2.5kHz, 4th order acoustic (2nd electrical).

Anyway, just guaging interest in this tweeter, or is everyone waiting for the accompanying 6.5" woofer to make a Mark Audio 2-way?

Bob has threatened to get me a set of the protos to play with... i have seen the tweeter at Bob's. They were still working on XOs. It has some real potential.
