I have a space behind my couch which is really just a void. I’d like a room filling, responsive woofer. I wonder what frequencies I’m missing and wondering if I can get some tactile feel and chest thump with a large woofer and more powerful amp.
Currently: 10” Onkyo HTIB type SKF 540, ported, “130” watt wamp. Two Infinity Crescendo’s 3006, cheapo Sony surrounds (5.25”/tweeter) and a BIC FH6 Center channel above TV, powered by Yamaha RX-V675 AVR.
The subwoofer does it’s job, I guess. But my issue with it is that it feels underpowered and far from “responsive”. It really does seem to be all that active to me, either because of an early drop (maybe around 35+hz or below)
Box size exterior could be 6x17x60” (WxHxL). I get roughly a 3.5 cu. Ft box from that, if I calculated right, more if I length to box to 72".
I could go a little longer 60+, a tiny bit wider 6+ and a tiny bit higher 17+. Wider or higher would require me to move my couch further out. I see that a Dayton Classic 12” is 5.5 inches from the inside of the frame to the edge of the magnet. I assume I’d need at least an inch behind it? This would mean the interior would have to 6.5 inches and with two ¾ mdf I’m looking at 8 inches total width
The room is 17.5x9.5x9 so about 1500 cubic feet, the room is entirely enclosed, one door in, one door out. Windows on three sides, brick wall on other. Concrete floor with thin vinyl plank flooring.
I don’t want to spend more than $400, the cheaper the better honestly. I have woodworking skills and all the tools that this job would require (well my father in law does at least). I do not care what the box will look like as it will be hidden.
I don’t now, but may eventually get an AVR with Sub EQ. For now I’d like to avoid a DSP/miniDSP/iNuke sub. I strictly want to stay with a plate amp.
Any ideas? Port could go out either side or up, whatever is best. Sub, presumably would have to fire at the couch. I guess the real question is, how much clearance from the magnet to the rear of the box is needed first and any major downsides to having the couch close to the excursion point of the woofer?
-Maybe a crazy idea, but what about two of these guys? Or start with one, see how it does and if it's lacking get another? Monoprice SSW-10 (~$150.00)
-Scrape all of this and go with an SVS PB-1000?? My wife will hate me and I may be forced to sleep on the couch.
-Build a sonotube with either a 12/15" to put in the corner in place of an existing speaker stand (would have to be 36" max height).
