Owner's Manual
Congratulations on your purchase of the
Definitive Technology C/L/R 2500 Shielded
Center/Left/Right Audio Video Loudspeaker System.
This revolutionary loudspeaker utilizes state-of-theart components (cast-basket homopolymer-coned
bass/midrange drivers, moving coil ferrofluid-cooled
dome high-frequency radiator, long excursion subwoofer, infinite power source amplifier, uniphase
crossover networks, etc.), a non-resonant monocoque
cabinet and low-diffraction construction in order to
achieve the most lifelike sound possible in your listening room for many years to come.
The Definitive Technology C/L/R 2500 is a compact high-definition loudspeaker system designed for
use in audio/video systems of the highest quality.
Because of its low profile, wide range, high power
handling and articulate clarity, it is ideal for use as a
center channel in conjunction with all surround sound
decoding systems, including Dolby ProLogic*, Dolby
Digital AC-3*, and DTS*. In addition, the C/L/R
2500 is ideal for use as an LCR (left, center right
speaker) as well as a rear surround speaker in all surround sound decoding systems, including Dolby Pro
Logic, Dolby Digital AC-3, and DTS, or as the main
speakers in a high quality stereo system.

Unpacking Your C/L/R 2500
Please Inspect For Shipping Damage
Each loudspeaker leaves our plant in perfect condition. Any visible or
concealed damage most likely occurred in handling after it left our plant and
should be reported at once to your Definitive dealer or the delivery company
that delivered your loudspeaker.
all cartons and packing materials in case you move or need to ship your system. Record the serial number found on the back of the C/L/R 2500 in the
appropriate place on your warranty card.
Please unpack your system carefully. Save
Speaker Break-in
Your C/L/R 2500s should sound good right out of the box; however, an
extended break-in period of 40-60 hours or more of normal playing is required
to reach full performance capability. Break-in allows the suspensions to work
in and results in fuller bass, a more open “blossoming” midrange and
smoother high frequency reproduction.

Since in most cases the C/L/R 2500 will be used as a center channel, we
will give hook-up instructions as such. If you use C/L/R 2500s across the
front (or a pair in stereo) simply hook-up each C/L/R 2500 by repeating
similar hook ups for the left and right channel C/L/R 2500s to their appropriate channel as for the center.
Connecting Each Speaker with One Pair of Speaker Wires Only
When the C/L/R 2500(s) are hooked up using simply one set of speaker
wire per speaker (with no separate low-level input for the subwoofer section) a special circuit takes an infinitesimally small signal from the speaker
level input and converts it to a low-level signal which then drives the subwoofer power amp.
With all the gold jumpers in place, (see diagram # 1) simply connect any
of the red (+) terminals of the speaker to the red (+) terminal of the center
channel speaker level outputs on your amplifier or receiver, and any of the
black (-) terminals of each speaker to the black (-) terminal of the center
speaker level outputs channel on your amplifier or receiver. It is essential
that all the speakers (center, left, right and rears) be connected in the same
way (in phase) to its own channel of the amplifier. If you experience a great
lack of bass, it is likely that one speaker is out of phase with the other.
