Here is the system in a 60 litre box filled with 40% damping material, using a port of 100 mm diameter, length 464 mm. The gray maximum output level is is based a guesstimated Xmax of 5 mm. A baffle step from a 300-by-400 mm baffle is included.

Seems possible enough...

I don't have any experience with using car subs in a house, but if you just going to use them for general use and nothing special, I bet a W0 would sound fine. I've had good experience with JL's in the past. As for the amp, I can't see how a properly sized/matched amp could possibly hurt the woofer.

I suggest using a sealed box to preserve the sound quality on a lower end sub like that. Just my opinion. Good luck.

Thanks Guys I figure if I get the box right they should sound great I mean if you go to the JL website It looks like they are putting the JL W7 in thier subs and charging $2000+ for it. So I guess I will be trying this.

P.S. Svante How much is the program in U.S. dollars?

Given the xmax (23mm) of the W7s, I'm thinkin' put the W7s in a sealed box (push-pull), with linkwitz transform , and a massive amp.

I'm sure you would have a killer sub.

I think I am going to use the WO's (3 of them) for now and leave the W7's in my car. Because I don't think I want to spend quite that much money on the amp it will take like roger said "a massive amp" to run those W7's.
Roger and or anyone else what kind of box for the 3 W0 setup do you think and I need some input on a amp also.
Thanks for the help guys!

The vented box Svante modeled looks promising. Of course, if you had 3 w0s you would need 3x the volume which would be over 6 cubic feet. (Are you married? (this is a joke, sort of...)) In terms of power I figure buy as much as you can afford. You can always turn down the gain if you have to much. For a more definitive answer look toward modeling.
Regards,
Roger
