My theater has pretty much been designed from this forum and past posts. The amount of knowledge and helpful people here is mind blowing.
The LCR's and surrounds have been ordered and I've picked up a bunch of the Crown amps that were on sale (again from a post on this site). Now on to the subs!
The guys over in the AVS speaker forum told me to go with DIY subs and check in here for help. My question is about the Stonehenge flat pack
, are they a good box for behind an AT screen? I thought about doing something like Popalock had before he went with 24"s and stuff 8 sealed SI18"s under the screen, but it looks like a ported sub would fit better. Assuming I go with the Stonehenge, are the SI18's a good choice for a driver? Or would the UXL18's be a better option? The new SI HST18's seem like a good candidate too, but I REALLY, REALLY, REALLY like the price of the SI 18's for the performance. They seem like the best value.
So if I go with the Stonehenges and the SI18's, do I understand the impedance correctly that if I wire them (as shown in the photo) I can use two 2 ohm subs and use a 4 ohm X4000 amp (1,350 watts per channel) and get about 675 watts to each sub? I know the SI18's only handle about 600 so I would need to turn the gain down, right?
Cost wise it's about $225 a sub (shipped) for the SI-18's, Stonehenge is around $260 (shipped) and the Crown X4000 was $300 (powering 4 subs per amp). That puts my cost per sub (including amp to power it) at $560 per sub or $4,480 for 8 of them. Is there a better way to spend $4,480 dollars on subs? I could get a couple Seaton's or JTR's for about the same money, but the pure volume of 8 ported 18" subs seems like a better way to go. Plus the thought of 8 ported 18"s hitting at once seems like something you would feel more.
Any help or ideas would be greatly appropriated.
