This is one I built for me. :)
The center section has torsion box construction bottom and sides, and the face frame is removable for the TV installation and for future resizing to fit a future TV. The upper frame hinges up to reveal the center speaker and amps that run the subs and seating vibrators.
The upper side equipment sections pull out to ease wire hookups.
The crown was attached to a piece of trupan and put on top in one piece.
The interiors are vertical grade black laminate applied to trupan. ( to keep the weight down as opposed to using black melamine )
The finish is natural Watco to ad some amber color, and after curing for 72 hours a topcoat of lacquer was applied.
Here are some additional pics of the setup.





The torsion-box assy.

The vacuum press may look innocent enough, but a 4’ X 8’ bag can apply more than 32 tons of pressure. :)
The corner units are to cover the home made subs and provide a shelf to hide the left and right main speakers. The subs are 4’ tall and each weigh more than 200 lbs. they have spikes that couple their mass to the cement floor. Each has it’s own 500 watt amp.

A shot of the corners with the fronts off.

Excellent Marshall. I really like the pull out electronics shelf as it makes it easy to get to the wires in the back. You’d figure that once installed, you don’t need to access the rear anymore, but I’ve been back into mine several times already. I see you’ve also built matching cabs for your corner speakers. Are there some in the rear too?

No, I have some small nht surround speakers. The corner units are to cover the home made subs and provide a shelf to hide the left and right main speakers.
I will add a pic of the subs before I hid them.

OMG, can I come to your house to watch movies?? Must be better than the theater…vibrating seats? LOL Very fascinating, I like the torsion box construction and the pecan/finish is beautiful. If you figured out all that wiring you truly are the king. I like the great storage under the equipment also seems you can never have enough of that. I have a couple of questions: First, the slides used for the electronics boxes, type (full extension I understand) and weight specs?? Second, What the heck is trupan?? Marshall, only saying this is an awesome project just doesn’t seem enough. Wow!

>First, the slides used for the electronics boxes<
The bottom pair are Accuride heavy duty full extension – 350 -500 lb load rating. and the top slides are KV 8400 standard duty full extension box slides- 100 lb load rating. The top slides are mostly for alignment.
>What the heck is trupan??<
I got this off the net. – -
TRUPAN
THE MERCEDES OF MDF
Trupan is a double refined medium density fiberboard produced from only fresh debarked Radiata Pine logs harvested from sustainable forests. By using only fresh Radiata Pine logs, no other species, or wood waste, Trupan is able to produce a very light colored medium density fiberboard. The use of Radiata Pine in the production of Trupan produces a fiberboard that is extremely easy to machine. The Radiata Pine content of Trupan tends to prolong cutter life. The double refining produces a board that is very consistent throughout its core, thus making it the perfect choice for edge profiling, moulding, and routing. Trupan is produced in Chile and imported into the United States.
TRUPAN ULTRA LIGHT—-weighs approximately 60% of a standard mdf or about 60 lbs per sheet of 3/4” 4×8. Trupan Ultra Light is the best choice for any use where weight is a factor. Trupan Ultra Light will machine very well.

Looks spectacular. It’s nice to build something for yourself every now and then.

that is amazing!!
I especially like the pullout area giving you room to get at the wires. A “surprise” bonus… Awesome

Marshall,
Since I will soon start to plan my home entertainment system, your post helps a lot with ideas. My mind already started working on how to plan mine.
Some technical questions:
Do you get any vibration in the wood frame from the subwoofers or the speakers?
What kind of cloth did you use for the front of the speaker cover. I know Rockler sells some special cloth for this purpose.
Do you use any ventilation for the receiver?
Great project,
Alin

Not yet. All of the raised panels at the cabinet sides, where the inside face is not seen, I apply a silicone bead around the perimeter of the panels. At the doors I put a bead in the groove. I also bed the glass in silicone.
>What kind of cloth did you use for the front of the speaker cover<
I have found that about any knit fabric that is slightly stretchy is acoustically transparent. This has been confirmed by several speaker building forums by people who know far more about this stuff than I do. :)
>Do you use any ventilation for the receiver?<
Actually, the hottest component I have is the DVR. I found a guy on e-bay that makes several different types of equipment and cabinet ventilation fans. Some have thermostats so the fans only come on when needed. I tried to find them on ebay just now and it looks like he is not listing them any more. :(
