7.1 Vintage JBL Surround Sound (4412 and 4312c)

[Mr. Widget]

Well, a pair of JBL 4645B's followed me home yesterday, so I guess that answers my sub woofer question.

That’ll do it.

Congratulations!

Long time, no update. I got the three doors installed, not ideal but they will do for now. I have been enjoying the theater, the current biggest problem with the audio quality being the lack of acoustical treatments. (Also it sometimes serves as a catch all for items which don't belong in there...)

To help address the acoustics of the room, I have been making wood framed cloth wrapped fiberglass sound absorbers which I still need to finish. I did however manage to finish a small skyline-style PRD out of douglas fir 4x4 scraps I had leftover from a project. It is almost 24" deep to scatter the bass frequencies down around 150Hz.



I plan to build some more acoustic treatments out of leftover wood scraps from various projects.

I also set up a basic two channel system with L100T speakers driven by a MAC1900 receiver, for when I don't feel like powering on the 7.1 system.

Here are some older photos, just before the doors were installed. These show the new amp and blueray player stand (solid chunk of douglas fir, 12x24x48), the new speaker wire routing system (insulators on the wall), and the new subwoofers installed. Also this was back when the room was still clean.
