After stumbling across this thread (after stumbling across the BEQ threa), I finally decided to pull the trigger on a BOSS setup. My seating is 3 Fusion Lagoons on front row, and a riser with 4 theater rockers in the rear. Immediately my plan was wrought with setbacks due to my layout and seat design.
First problem was I could only accomodate a riser of about 3" and I really didn't want to do that because my rear riser isn't very tall (10-12 inches). Plus the metal frame on the seats was such that the woofer could not extend ANY into the underside of the chair. So that plan was out pretty quickly.
After some quick measurements of the frame, I figured I could direct mount a shallow sub. But still it was tight. I love the Fusions and they are well-built, but their beefiness doesn't lend well to space for a BOSS. I ordered a 10" MB Quart sub (just one to make sure I could get it to work) and started measuring the space for a mounting board. After cutting the board and test fitting it, I could NOT get it past the metal frame of the reclining mechanism. I trimmed, cut notches, everything.
Then it occured to me that I could pre cut the board and if I could squeeze my impact driver in there I could reattach it with pocket holes, then pocket hole the whole thing to the frame. It was a long shot, but it worked! (pics below)
Hooked it up to a cheapo used NU1000 I picked up and we're off! Only had a short time to play around with it, but so far it's great! I have no comparison (other than Archaea's thoughts) to a platform type BOSS setup, but my guess is this is going to be more of the "punchy hit" bass than the "wobbling" bass some of you nuts are getting with your hovercrafts!
I'm still playing around with crossovers and levels so I'm still getting it dailed in and figuring out what I like and don't like. So the plan is to do direct mount on each front recliner and nothing on the existing riser.
Ordering the remaining 2 subs today. Can't decide whether or not to get 12's or 10's.
Currently have a LPF set on my MiniDSP at 60Hz. Comments welcome and thank you to everyone for their innovation and input!
