Alpha Center
Classy looks and smooth sound
• Alpha
™
Series
Infinity calls these speakers “a symphony of sight and sound,” and
it’s easy to see — and hear — why. The Alpha line benefits from
technologies developed for use with Infinity’s high-end Prelude
line. With solid, braced enclosures and Ceramic Metal Matrix
Diaphragm drivers (see box below), Alpha speakers provides big,
yet precise and natural, reproduction of sound. And, with black
ash or cherry vinyl finishes, these speakers look great too.
Infinity • Alpha 25ES
Dipole/bipole surround speaker
For enveloping surround effects in your
home theater, count on the Alpha 25ES!
A single speaker sports two angled
driver arrays, with a 1" C.M.M.D. tweeter
and 5
1
⁄
4
" C.M.M.D. woofer on each array.
If you have 25ES surrounds positioned
to the sides of your choice listening spot,
select the “out of phase” dipole setting for
a diffuse field of sound. If you place them behind
you, choose the “in phase” bipole setting for clear
off-screen effects. If you’re a multichannel music
fan, the monopole setting gives you directional
sound from a single array per speaker. Speakers
sold individually.
Specs:
acoustic suspension • frequency response 60-22k Hz
(±3dB) • 8-ohm • sensitivity 87 dB • handles up to 125 watts

Infinity • Alpha 40 Tower speakers
The Alpha 40 is a great reminder of why
people love tower speakers. You get sleek,
solid good looks and expansive, lifelike

below). This tower boasts a 1" C.M.M.D.

— you don’t need tons of watts to fill your
room with sound! — as well as biwirable,

What’s behind the Infinity sound?
Infinity’s C.M.M.D. drivers are the secret to their
open, detailed mids and highs and
punchy bass. The sandwiched
ceramic-aluminum-ceramic design
gives the drivers the stiffness needed
to reduce resonances, and the light-
ness needed for responsiveness.
