Hi Graeme,I agree with you 100% on the crossover point for compression drivers. I know some of the really old stuff was made to be used down low, but the new parts don't sound good to me when crossed over low. Plus they don't handle any power so you lose all the dynamic range benefits if you push 'em too low. And probably more than all of that, I just don't like having a crossover in the vocal range.
Your subwoofer sounds great. I'm interested to see it when you get it done. I've had a few new projects on my plate too, so I've been too busy to loook around and see what everyone else is doing these days. Please keep us posted.
