Subwoofer and Lower Center Channel Speaker Here's a better photo of the subwoofer with the lower center channel speaker
to the right of it.
The new Velodyne Digital Drive Subwoofer is very cool. It is adjusted by
a remote control. Housed in the subwoofer is a tone generator, a real-time analyzer, and an 8-band parametric equalizer. The
subwoofer has outputs for audio, a measurement microphone and video. These outputs are connected to your preamplifier and
monitor. Through the use of the remote control the subwoofer then generates test frequency sweeps through your mains speakers
and subwoofer. It then plots the real-time frequency response of the room at the location of the microphone. Using the remote
control you adjust the parametric equalizer to smooth the frequency response.

Closeup of Polk Audio SDA-1C Speaker
The screenwall and shadowbox assembly is constructed on a stage that is
filled with 1,000 pounds of sand to reduce vibrations. The main speakers in turn are sitting on 15 inches of solid concrete
block. The block is covered in black carpet to protect the speakers from abrasion. This raises their tweeters so they are
vertically centered on the screen.

Side Surround Speakers
I use Polk Audio f/x500i speakers for my side surrounds. They are set
for dipole operation. These speakers are concealed inside columns. Also concealed in the columns are compact subwoofers.
The full range side surround signal is sent to the subwoofers and to external crossovers where the bass below 80 hz is
filtered from the Polk dipoles. The net result is full range surround channels.
This arrangement was setup to take advantage of my Lexicon processor's Bass
Enhance feature.

Surround Back Speaker
This is one of the two Polk Audio LC265i In-Wall speakers that handle the
surround back channels. These are Polk Audio's top-of-the-line In-Wall speakers, and they are mounted inside Polk's
performance enclosures. The enclosures are quite large, 55" high x 14" wide x 4" deep.

Acoustic Treatments
The entire front wall, the soffits and the first four feet of front side
walls are all covered with one inch of rigid fiberglass. The remainder of the room has fiberglass from the floor up to ear
level. One inch of polyester batting is placed above ear level. The fiberglass is used for sound absorption. The polyester
batting is less absorbent so it permits more reflection and diffusion of the sound. Fabric is stapled to the furring strips.
The plywood fixtures with the circle in the middle permits attaching fabric and anchoring sconces.

These Middle Atlantic Slim 5 racks are on casters. They can be pushed from the
back wall to gain access to the rear of the equipment.

InFocus ScreenPlay 7205 Projector
The InFocus ScreenPlay 7205 DLP projector has a bright image and the
colors are very accurate. All in all I'm very pleased with it.

Buttkicker Tactile Transducer
This is a photo of one of the two Buttkicker tactile transducers that are
mounted inside the seating platform. They are very powerful and do a good job of shaking the rear row of seating down
to infrasonic frequencies as low as 5 hz.

Jaymar Cinema Seating
These cinema style recliners are very comfortable. The motorized reclining
mechanisms are a considerable improvement over manual recline.

Jaymar Cinema Seating
Here's a better view of the first row of seating. I'm a big fan of
the Buttkicker brand tactile transducers. The problem is that they are rather large and will not fit inside the chairs
without interfering with the reclining mechanism. I got around that problem by installing a transducer inside each of
the wedge arms in the front loveseat. The wedges are rigidly attached to the center chairs and provide lots of vibration.
In fact the vibration is so strong that even though the end seats are not rigidly attached to the wedge arms, the vibrations
still carry over and provide a very satifactory effect.

Wet Bar
In the rear of the theater we have a small wet bar. To minimize noise I installed the very quite Echelon
model U-Line refrigerator. I used Techline cabinetry. They were the only manufacturer I could find
that offered dark gray contemporary cabinets.

Sconces
Here's a closeup of one of the five sconces. These are made by Justice
Design Group and they are literally works of art. The globes are hand-blown French glass and the bases are glazed ceramic.

New Wave Contemporary Rug
This hand tufted contemporary wool rug inspired by the art of Gustav Klimt
works well with the Art Deco theme of the theater. Along with the sconces and seating, it adds a colorful departure
from the dominant monochromatic grey and black color scheme. The wool probably aids in the acoustics by helping to absorb
sound reflecting off the floor.
