SO ive been a long time reader of this and other home theater forums. ive decided to take the plunge and dive into the world of DIY HT subs. ive done plenty of car stuff in the past. my HT rooms a basement room about 30x15x8. power will be provided by an inuke3000dsp.

ive decided i want to use the new SI HT subs. i love SI as a company and used to love there subs in my car audio projects and i currently run 2 BM mkIII's in my truck.

ive decided on either 2 sealed HT18's in 4.5-5ft3 each

or a single F20/lil wrecker with a SI HT15. im leaning toward the lil wrecker since i have the room and i like the low end capability over the or f20.

with the good price of the SI subs and the high prices of building materials i think im looking at around the same cost to do either. $500 + amp

Just wanted to get some opinions on SPL/SQ capability's of the 2 setups 60% movies / 40% music

It has been my understanding that with the F-20, you will get gobs of output from like 50hz and up, but it doesn't extend very low, probably 20hz or so with some lower dbs at that point. I would go with the duel sealed SI 18's. You might not get as much output but they will extend lower. I am not sure about that lilwrecker or what ever it's called, and I may be wrong about all of this, so I am interested in hearing some other opinions on this. I would imagine that if you did go with the F-20 variant, using a high quality Stereo Integrity 15" driver would be better than the Dayton DVC15, right?

You've got it backwards, the f20 hits plenty hard in the 20-50 range.

I don't think the SI15 works in the f20 enclosure. And while it models well in the lilwrecker, it has yet to be tried.
