They're for sale through WES components (who I'm sure you've heard of), and they are absolutely stunning. My home theatre sub used to reverberate a whole living space that was about 12m x 5m x 2.5m... and that's an awfully big living room for one little sub. The 10" in my boot is also very impressive, as the Shazzy Phantomchic can testify.Have a look at the range:http://www.d-s-t.com.au/caraudio/pdf/peerl...omotive_wes.pdfI think given your power needs & space restrictions, the 12" XXLS 4+4 sub might be an option. It's on the last page, and will suit those small spaces nicely (20.4L Vas).The trade off is that the Fs or resonant frequency is a high 50Hz, and you'd need to watch that parallel impedance (1.2ohms!!!). Now there's also the 12" XLS 4ohm on page 6, and the Fs on it is a much more acceptable 28.2Hz, and needing a 2ohm stable amp, you can whack in two and run it at 1ohm parallel! ...but it's recommended Vas is 80L, which you clearly don't have. Still, my 10" (4ohm XLS, page 4) has a Vas of 21.4L and yet it sounds just fine mounted free air where the factory sub used to be. Go figure.I think when it comes to getting it right, the numbers can only tell you so much. The best test is using your ears. Give it a go! If it sounds good, go with it.Incidentally, my subs cost around $290 a piece, so that may give you a ballpark on the 12" versions. To find out for sure, ring WES: (02) 97979866.

They were only plain old rectangular and I still managed to balls it up. You could charge $400 for what you've done there... Link to comment Share on other sites More sharing options...
Terebro Member 170 Member For: 19y 10m 1d Posted 15/06/06 09:50 AM Share Posted 15/06/06 09:50 AM Ive had my subs for about 6 months, but because Ive been concentrating on performance upgrades they've only had about 1 months use They're rated at 200W RMS, Single Voice Coil 4ohmThat fusion amp you're looking at will only deliver 125w to those 2 fusion subs at 12.6v Because they're Dual Voice Coil subs they'll have to be wired in parallel, drawing on a 4ohm load, and that Fusion amp only delivers 250w at 4ohm @ 12.6v.As mine are SVC, with that amp they'll draw a 2ohm load giving the subs they're rate 200W each Link to comment Share on other sites More sharing options...
