So for a while I've been planning the conversion of our small single garage into a small cinema room, and today I finally got a chance to start work. I've already had the up-and-over door blocked up a while back, so the next job is to construct a baffle wall for the front speakers to fit into as well as the subwoofer. Here's the first piece of timber glued and screwed onto the ceiling, with the left, right and bottom lengths measured and cut ready to go. Click through to see the progress today!
Once the other lengths of timber have been glued and screwed in place, you can start to add more frame work to support speakers, and add strength to the wall. It's really important to make sure your left and right timbers are vertical, so keep checking everything with a spirit level to make sure your wall will be perfectly straight!
Now I've started to add some upright bits into the frame, as well as make an area in the bottom left for my subwoofer. The speakers will rest on part of the framework that I'll add in later. As my subwoofer is wider that the space between the upright pieces, I've used a shorter bit of timber to make sure all my speaker positions are correct.
So here I've added the last two upright sections, which make a nice symmetrical framework ready for my LCR speakers. The subwoofer section is plenty big enough and thanks to a few extra pieces of wood doesn't affect the LCR positions. I've also started to add the pieces that support the front speakers, starting with the left one.
After adding the rest of the LCR supporting timbers, I've cut, glued and screwed pieces of MDF to the framework to sit the LCR speakers on. This gives me a bit more depth, and will allow me to slightly angle the left and right speaker into the room.
So here's the baffle wall constructed. You can see the LCR shelves in place, as well as a similar piece for the subwoofer in the bottom right. The most important thing is to screw everything down nice and tight, using glue wherever possible. The reason for this is to make sure you don't get any nasty rattles or vibrations when watching a movie.
The next step will be to run speaker cables for the left, centre and right loudspeakers and power and signal for the sub, then add some absorption material behind the baffle wall.
