Earl, I don't want to build loudspeakers, I just want to listen to them.

Actually I think we are ready fore a 3way, or at least a 2.5way

And I don't want to build speakers that I don't think will work well. You asked how you could "convince me". I'm not convinced and doing yourself - or paying me to do it - is what it would take. (You don't really want to know what a custom design would cost - trust me.)

We already have a 3 way system. Don't forget the subs.

Best, Markus

Why won't they work well?

Lets just say that I wouldn't expect them to work significantly better, yet be eight times as big and about ten times as expensive. Sounds like a real winner to me - NOT!

Any other specific reasons besides size and cost? Why is the magic number for directivity 1000 Hz and not 500 Hz or even lower where geometric acoustics still is a valid concept?

My understanding is that lowering the crossover frequency from 1 kHz to 500 Hz would necessitate adding a high frequency driver because (like Earl said) drivers which can go that low cannot also go high enough, and the inevitable compromises arising from the additional complexity would likely more than offset any advantages from maintaining constant directivity down to 500 Hz.

well, size and cost certainly are significant issues- I guess the other part of it would be that unless you were going to attempt full-bandwidth, you'd have to find a woofer that's directional at the XO while still behaving well, and there are a VERY limited selection of good 30" drivers.

Would love to see you do one with the ginormous fostex woofer and a 30+" waveguide though!
