Center done, mains almost done – waiting on parts!
by on Mar.25, 2010, under RS150 MTM Translam
I know I owe you guys some sexy pics but this will have to do for now. I’m just waiting for some parts that will be here on Friday, and I should be done this weekend, woohoo!
I finished up the center channel which will be hidden in the entertainment center behind grill cloth. Here’s some snaps of the partial BSC crossovers for the RS150s and the 27TDFC. They’re on MDF, 16 gauge wire between components mounted with hot glue.
The crossovers are mounted with velcro connected with 12 gauge speaker wire (monoprice). The box has the dampening on the walls with a little bit of acoutica-stuff/polyfill/whatever it’s called in the enclosure.
I’m still waiting on the inductors for the RS150 crossovers for the mains, but I went ahead and put everything together. Both the front and rear baffles are floated with screws through oversized holes and washers to allow for expansion. Here’s a pic of the gasket before attaching the rear baffle.
The stands were finished separately: primer, black paint, polycrylic for the MDF and sealer with polycrylic for the BB ply. After finishing, the pieces in the center of the stand were glued together with wood glue to make one piece. It was then attached to the bottom and top pieces using screws. I didn’t want to use any glue on that part in case I wish to make the stands taller later on. The stands are attached to the speaker with 1/4″ socket cap screws threaded through the hurricane nuts already in the bottom of the speaker (see previous posts), with rubber grommets to create a small gap. Rubber feet on the bottom of the stands for the wooden floors.
The front baffle is attached with wood screws that are screwed in from the rear by reaching my hand through the driver cutouts.
As for the rear baffle, I would have done the same as the front baffle if I could do this over. Instead, I used socket cap screws visible from the back, but they weren’t very nice to the surrounding paint. One of the bolts has a large standoff that I was planning to use to anchor the speakers to the wall or the entertainment center. Now I’m not confident I’ll even use them, so that was a mistake.
Here they are in room. They’ll be a little farther apart than this when all is done.
And here’s with the pull-down projector screen. The center channel is behind all that grill cloth in the entertainment center.
