Eminence driver that can handle 1250 wattts RMS, with heat sink
type: item
description: I saw this at parts express: Part Number 290-434 Sells for around $350 each. (Already has a heatsink in the front of the cone, I think). It's an 18 incher with 97 db eff that can do 1250 watts rms. Xmax: 9.8 mm. Wonder what would happen with 2 of these and a suitably modified 12 pi cabinet. Should get 135 db SPL continuous you think? -akhilesh

description: That's the Eminence Kilomax, and you're right, it uses a small vented heatsink, probably why they were able to increase power handling 2x.

description: Wouldn't work to good, for one thing the horn cabinet would be massive, another thing it dosen't have the magnetic strength (BL) for good cone control in a long horn, the fs is to high so it would have trouble getting down to 30hz. The Qts is also a little high for horn loading, you want Qts to be like between .2-.4 preferably. It would probably be kick ass in a horn that was designed for 50hz though, but not 30. Try running some models in McBeans and see what you come up with. HTH Bill W.

description: HEYYY!. My new ALtec system is up in my family room, and guess what?! My wife thinks it looks cool! I think bringing in the A-7s was great to set the expectation bar really low in terms of WAF...she loves the "only 5 cubic inch" boxes I have now. -akhilesh
