"So, was the horn you built yourselves any good?"
Actually yes -- frequency 'curves' were basically frequency 'lines' and off-axis was DAMN good - even the bass went to about 32 Hz -6 dB - which was measured by a government lab - and not just an 'ad spec.'

Soundhound,
Have you measured the S/N? If so, what does the S/N ratio measure on your modified 950? You measured the S/N to be worse on my unmodified red dot 950 than on yours. But the hiss was louder in your 950-based system because your speakers are horns and are more efficient than mine which are direct radiators. Anyway, I hope the modified 950's have consistent S/N readings rather than some being measurably better than others. I'm no expert in these matters though.

Not trying to offend, but .... actually it is the sensitivity (or efficiency) that causes the noise problem to be more obvious. It's a pretty easy concept and SH and myself have both explained it - did you miss that part?

Will: I don't have a replacement 950 yet. There was only one prototype that was circulated. I had it for a day, and measured/listened to it. My findings are in this thread from yesterday, I believe. It basically has a _real_ improvement of about 12db, which is quite big. I am familiar with the ICs and other parts they were replacing, and I can see no reason that there will be any variation between units to speak of. Why your's and mine measured so wildly different is anybody's guess. Once they get the units modded in Malaysia, We should get them, and live in blessed silence - aside from the car crashes, explosions, and other acts of wanton violence

Yet another reason I'm happy to no longer be a habitual 'early adopter'....
I wonder if the clones ever had this problem, and whether the 'fix' will eventually roll over to them?

Come on Charlie, we know you love to live life on the 'bleeding edge" Ah, the CLONES!! _That_ should be very interesting! I really feel bad for the Outlaws having to deal with this mess....I'm sure the clones had the same problems.... [This message has been edited by soundhound (edited November 25, 2002).]
