Eminence driver that can handle 1250 wattts RMS, with heat sink
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
Re: Eminence driver that can handle 1250 wattts RMS, with heat sink
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.
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.
Thanks Wayne & Bill. I figured you guys knew about it, i was just browsing thru the catalog and saw it, and with the memory of the shootout fresh in my mind, thought about psting it here. -akhilesh
Design one up you can build it in my garage but they'll be bigger than your A-7's then you can see the look on your wife's face when you bring them in through the door LOL. Bill W.
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
5 cubic inch, don't tell us you went bose on us.:) bill
I meant 5 cubic feet. LOL -akhilesh
I figured that's what you meant, I'd like to hear them at the next get together when ever that will be. Bill W.
Two people have volunteered to host a meeting, Leo McIntire and Jim Denton. So I'm waiting for them to set a date time and make an announcement. I'm glad too, 'cause it's been a while.
YOu don;t have to wait. Bill & Wayne, you are both invited to come by and listen before then. Let me know if you willbe this side of town, and we'll set a time up. -akhilesh
