Re: Unity Patent

That's the same driver compliment I'm using. The compression driver is obviously easy. Appropriate 12" woofers are not too hard to find - I'm going to use EVM12L's, although it looks like they've now been discontinued. The mids are the tricky part - I'm using $10 MCM woofers as detailed on my webpage. The Galaxy Hotspot drivers look like they would be better, but the 4 I bought were all vastly different than the specs indicated giving them approximately the same performance as the MCM's for 3x the price.

I think the TD-1 is spec'd as having a 75hz low end. As you go lower, the horn will lose control of the pattern depending on how large and what angle you make the mouth. I'm shooting for around 75hz so I can crossover directly to a sub.

I wish you could have heard my prototype at Lima, Mike. We did only have it running for a few hours, though...
