...was my response when my wife asked "You didn't just build a subwoofer for the end table base, did you?"
have gone with a veneered cab to blend better with the existing end table top, but this build was quick and dirty. Needed to augment my earlier UM12-22 build at the other end of the couch in our family room, not the ideal location but gave me the space needed for another UM12-22 in a ~4.2 net cuft box that models around 19Hz.
This is what I was dealing with. Look at all of that wasted space.
This cab will be 19"W x 23"D (total, with 1/2" outer baffle) x 22.5"H. It will replace the legs/shelf of the end table. Port built and attached (remembered to hold it 3/4" from the front this time
), back and first side attached to bottom.
Bracing, front and other side all in place
Mounting hole and port opening cut out, top attached. Almost there
Used a piece of 1/2" thick ply for the front baffle. Cut outer driver hole and rounded over that edge with a 1/4" bit. Applied to front with glue/clamps and 18 gauge brad nails, routed out port hole with a flush trim router bit and shot driver edges and port with rattle can black paint. Rounded all outer edges with the 1/4" bit, filled all edges and nail holes and sanded . Rolled on Duratex after this.
Removed legs, cross supports and shelf from the existing end table, and placed some of those self-sticking felt strips on the underside of the top
Easy-peasy, just place the existing top over the Big Black Box (as my wife has come to call them
Not sure how long before she tires of the look, but I have no issue with it. I have always liked very contrasting textures/colors in builds, so this will probably stay this way for quite some time. The legs and shelf are stored in the basement so I can move this at any time, and put the end table back together as it was.
The 2 UM12s flanking the couch sound great in the MLP. I still have work to do to get them dialed in, but so far I'm really liking them. They hit hard on the lows but lack mid-bass punch, but I'm replacing the front L/R with something that should provide some of that. Like I said, this is our family room, so nothing crazy.
Figured I would give others that may be in a similar situation some ideas. The space is there, sometimes we just have to look hard for it. Have fun!
