SPECIAL REPORT: Analysis of a Home Theater - Chicago Sony G90 CRT Projector StackI thought I’d post a write-up dissecting a
well thought out home theater that I recently
visited in the Chicago area, as it’s one of the
best home theaters I’ve been witness to. The
video system consists of two stacked
Sony G90 9”
projectors. Stacking is an application of two
projectors where both projectors are projecting
the same image on the same screen, thus doubling
the brightness of the image. The projectors of
course must be very accurately aligned so that
the images are exactly on top of each other. The G90s are driven by a
DVDO VP50 scaler,
and sources include a Toshiba A1 HD-DVD player,
an Xbox360, a JVC 5U DVHS machine, a Sony PS3 as
BluRay player, and an HTPC. Everything but the
Xbox360 is fed via HDMI to an NEC ISS 6020 via a
Moome HDMI card with gamma correction. The audio receiver is a Sony Sony 4ES 7.1
Receiver with true 110 watts per channel. All
main speakers are being driven with the amps in
the receiver, the 2
SVS PB12 Plus/2 Subwoofers
are self powered. The speakers are
Klipsch KLF-30 fronts with
matching center channel and 4 Klipsch RS-45
Surrounds (wired for 7.1 surround). The screen
is a custom built 10’ wide 16:9 ratio
SMX, which
is acoustically transparent. The L-C-R speakers
are located behind the screen in a separate area
fully accessible for tuning and maintenance. This system excels in performance in my
opinion, and is based primarily on how the room
is laid out and set up, and this is what I want
to concentrate on in my report.
