Home theater update: New placements, new wiring.

So I got the receiver and PS3 moved out of view, which is awesome; It reduces the number of non-presentation light sources.

I started with a 100ft spool of 16ga, but I was losing 30db between the receiver and the speakers. I just finished ripping that out and replacing it with 12ga copper.

New spool of speaker cable

wiring above receiver

Top two (copper) are 12ga rope-braided speaker wire. (Dayton SKRL-12-100 12) Pinned as a pair with 3/4" plastic cable staples, also picked up at Home Depot. They replaced some crappy 16ga I'd been feeding the front left and right channels, whose speakers consume up to 100W each. I was losing 30db across the 16ga; It's a 50ft run.

The bottom two are RG-6, using F-type-to-RCA adapters on either end; They're actually carrying headphone-level audio from the receiver to the subwoofer, whose internal amp has a built-in crossover. Once I get my receiver-side crossover set up, one will carry plain cable, while the other will carry LFE.

I did what I could to reduce cable strain.

The remaining crap isn't my wiring; It's network, power and cable.

Wiring leading to receiver and video source.

Top cable is HDMI, leading to the TV, pinned with 11mm round cable staples I picked up at Home Depot.

Next two (copper) are 12ga rope-braided speaker wire. (Dayton SKRL-12-100 12) Pinned as a pair with 3/4" plastic cable staples, also picked up at Home Depot.

Hanging grayish cable is a plug for the light in the room. I've got it stapled, but I'd *really* like to be able replace the light and wire it in directly. At least I've got it stapled, so it's not hanging down as far...

View in the dark

Main menu in the Ghost in the Shell menu.

Only annoying light is the power LED on the TV, and I can take care of that with some black electrical tape.

There's also some reflection off the ceiling. Not sure what to do about that yet. May try using a black diffuse covering if/when I put some R13 fiberglass up there.
