I'll be building a slot port variation of the VBSS to fit behind my couch for some punchy nearfield bass. A pair of them will run the full length of the couch, each cabinet coming in at 55" wide / 27" tall / 12" deep. A single run of 3/4" walnut will top the twins for use as a shelf behind the couch.
These will be for a living room, 50/50 music and movies, not obsessing too much on critical listening or HT dynamics. I will be building a pair of DIYSG MTM Apollos for front channels (thanks Eric, those drivers are beefy), and a 15" Ultimax to cover the low bass region (builds for both coming soon
- a relative term with a 3 month old). Because the room is fairly large and opening to other rooms, I wanted to bring in some nearfield bass. A little research and a sale a parts express dropped me on the doorstep of the VBSS.
The twins will be run in parallel (4 ohms) off one channel of a NU6000DSP, and the Ultimax with the DVC wired in series (4 ohms) off the other channel. Because the cabs are so wide, 5'x5' baltic birch made the best cut sheets - 2 sheets per cab @ $35/sheet and I'm at $140 total for structural lumber. Add in the walnut cap and the build starts to stray a little from the value part of VBSS, but still an amazing value for the aesthetics and performance.
Each cabinet has a net internal volume around 7.7 cu. ft. and are tuned to 27.5hz. I went with slot ports because I could shape them to fit the 12" depth easily and also because I can push them all the way down to the lower edge of the cab so they will fire into the space under our raised couch.
Here's some modeled screen grabs to give you guys an idea of what's to come. I also got in contact with
to have him give the design a once over, so there may be some edits.
Hope you're all well.
