The Bass trap


Parallel Sound rears it's head Wisconsin style!

Well the Wisconsin winters are cold and we need a place to hole up in, and so it goes, so it goes. 

With a few weeks to come up with a design that works in the basement, the frozen ground has been broken. Come late January I predict, we will be  rockin' Midwestern style, cheese heads and all.


As old concrete goes, it's pretty hard. Not the 6000 PSI stuff though. Another good thing - nothing is straight and square as construction goes. Pretty cool quarter bubble off.


Not sure how it's gonna' sound yet but it looks good on paper. Another underground concrete bunker with lots of Owens Corning to the rescue.  This is the moisture barrier going in on the outside world underground walls.

The drywall went up pretty easy except for a couple spots. I saw 7 ft. studs precut at Home Depot and scratched my head and as it turns out, the whole basement is about 7 ft high. Go Figger WI style.


Our underground view of the outside world. Ground level is at the bottom of the window which is nice.  The window is usually covered with ice when it's below zero.


This is gonna be the "room" room. Should be pretty lively and controllable and sound great, once all the stuff is in the control room and we treat the duct work.

Here's the bass trap before being covered up. It's about 16" deep and about maybe 5 feet across. It got pretty damn itchy after this doo-dad went in.
The drywall shell is done and primed with Home Depot oops bin green and this is the front wall framing in place. Standard 58 degree angling is a little short but it's what fits the space.


The drywall in place for the front wall. Tried to keep the window accessible a little for the summer months but in the end it's covered up.

The electric behind the racks gets a boost. Wall warts usually eat up all the outlets so I overdid it a bit. From experience you can never have enough outlets. We went with two 20 amp circuits, one for the studio and one for the "room" room with the guitar amps and stuff.

Here's the drop ceiling going in. Was a pretty tough install with the 7 foot ceiling. I didn't want to eat up the room so I ran it as close to the rafters as possible. This meant it had to be installed rail/tile as opposed to all the rails, then all the tiles. There's about an inch of clearance above the tiles - ugh!.


The dead end gets it's treatment courtesy of fake 703 from some office cubicle panels I've been hoarding for a few years. Finally found a use for'em. It's the old itchy fiberglass which needs to get covered up quick.

Well the wall treatment is done and looks pretty good. I covered up the insulation with budget Wal-Mart bed sheets and a power staple gun. The trim helps break up the wall and needs a coat of white wash.


This is the problem area. It's a little alcove that's kind of unexplained in the plan of the foundation back in 1947. Doesn't seem to be a real reason for it to be the way it is. I ended up making the back wall a small bass trap and we are going to put the slap machines in here.

I set up a test rig to see what the room sounds like. Just simple speakers and amp for now. Still have more diffusers to place but we need to blast something to the mix position for a while.

Well she sounded pretty good and in the gear went. Felt pretty damn good unpacking the boxes. Still got a little odds and ends to clean up but it's alive!


Lookin' towards the window to the room-room. The window turned out good and is a pretty tight seal sound wise.


The computer/speaker area is a little tight but it works.  I'm gonna swap the placement of the Tannoy's and the NS-10's to see what happens.

This is my buddy Matt's favorite view. We're thinking of installing a space shuttle style sleeping chamber in the cubby hole for those nights where absolute quiet is all that will do.



Behind the racks is pretty clean so far. Always a problem area, hopefully it will stay that way. We'll see how long it lasts.

Well all in all it was a pleasurable experience building the joint. It was a lot of work and still have a little to go, but the money pit is in place and we can rock. It's a little small sound wise but if we keep the volume below stun level (good luck) it'll be OK.
