would like to add 2 subs to compliment bookshelf speakers, but need to hide them under the couch for WAF. low couch, i've only got ~7" of height to play with. but the couch is 38" deep and 80" wide. so if i go upward firing, 0.5" plywood (lots of bracing), and only use 1/2 the depth of the couch, i can get at least ~4.5 cu. ft. of internal volume. so box volume isn't a huge issue. But driver depth, and how much space i need to keep behind the driver may be.
was wondering if anyone had thoughts about a traditional woofer, something like a peerless 8 inch or 10 inch SLS subwofer, that would only be 0.7-1.5" away from the "back" wall of the enclosure. Or looking at shallow mount subwoofers (which seem to be marketed mainly for car audio), like the Dayton Audio LS10-44, Dayton Audio LS12-44, Pioneer TS-SW2502S4 10-Inch, Pioneer TS-SW3002S4 12", JBL WS1000 10", or JBL WS1200 12".
anyhow, would be putting them into a separate simple sealed boxes. If i can make a small enough box, i might be able to squeeze another one towards the front of the room (3 total). I have a Mini-dsp unit to allow for EQ-ing if necessary. Although i live in an apartment, so i'm only looking for extension down to about 40hz before falling off (anything lower = way too annoying for neighbors). Listening levels don't get high, so even with EQ power levels will likely be very reasonable.
thanks for any input/thoughts/comments/suggestions!

Downward firing would be better than upward under the couch, unless you are looking for something other than sound from them.......
downward firing is also possible, just requires chopping out that much more useable volume. how much space do you have to keep between the driver face and the floor?
similarly on the angled idea, how much "breathing" room does the driver need?

Have a look at this little subwoofer, it might help answer a few questions for you Pluto + subwoofer
+1, though for 'sub' duty, I flipped it upside down, so it's angled into the carpet or at least a large scrap of damping material, old accent rug or similar to preload the driver a little and add a bit of an acoustical XO slope order increase.

Something like this scaled to fit your dims may also load nicely. You could copy the design concept from the pics and maybe go with some 8" subs etc

When I saw GM's post it reminded me of that box, and how it could probably fit the bill quite nicely if the dims could be made to work out etc.
Just a thought but maybe you could put some extension feet on your sofa to get it up a couple more inches.
Or he could take it a tad further.. Build a platform riser full of subs, perch the couch on top (well secured), add a couple of stairs to get you up to it quite comfortably and wallah! This is for a WMATF .. Wife Must Accept This Factor 😀
So many problems solved without that pesky WAF
lol..
Ha! Yeah, Don't think that would fit into the mid-century look she's got going. The real reason I'm looking to only use 1/2 the depth of the couch is that you won't be able to see the sub back there unless you're on the ground 😛 .
Thanks for the suggestions guys. I like the angled idea, and will play around with that.
No one has said anything about shallow mount woofers. Does anyone know if anybody has done any testing with them? Do they actually perform worse?
oh and yeah, peerless makes some too:

Probably ~100hz, although if I figure a small box for the front of the room I might mess around pushing that up to 150
I use four 10-inch Neodym-Drivers in a small closed box as couch subwoofer.
Half of it under the "armrest" , the rest of it visible between the Couch and the wall next to the couch. Subs are firing towards the couch.
The table is used for drinks or the remote control.
I think my wife has not yet realized that there are speakers inside.
