In search of great-looking, great-sounding Infinity Alpha speakers? These sonically appealing, visually attractive Alpha 10 bookshelf speakers are waiting for you. They offer natural, uncolored sound and small cabinets — perfect for discreet positioning amidst your decor.

The Alpha Series takes advantage of Infinity's long history of speaker design, pulling technologies like C.M.M.D. (Ceramic Metal Matrix Diaphragm) drivers from much more expensive high-end lines for use in these speakers. That's why you get such great sound! The Alpha 10 bookshelf pairs a 1" C.M.M.D. tweeter and a 5-1/4" C.M.M.D. woofer in an small, sleek video-shielded cabinet. Dynamic, lifelike mids and highs, as well as significant mid-bass, flow from these little troopers. The Alpha 10s are a good choice for surround speakers; they can also be used as front and rear speakers in a smaller home theater system, or simply paired with a subwoofer and used as stereo speakers!

Recommended center: Alpha Center.
Recommended surrounds: Alpha 10.

Why choose bookshelf speakers?

Bookshelf speakers may be small in size, but they can deliver surprisingly big sound. Some ultra-compact models even fit on a desktop. Most are right at home in tight spaces like shelves, so they're usually good choices for your home theater's rear channels. For the best performance, try placing bookshelf speakers on solid speaker stands to help the sound really "open up." If you want full bass impact, add a powered subwoofer and enjoy punchy sound that's as deeply satisfying as that of floor-standing speakers.

Features

Ceramic Metal Matrix Diaphragm (C.M.M.D.): Infinity's C.M.M.D. technology delivers accurate performance with dramatically reduced distortion for incredibly lifelike sound. Additionally, the C.M.M.D. drivers can withstand extreme temperatures, moisture, humidity and sunlight.

Woofers: The 5-1/4" C.M.M.D. cone woofer virtually eliminates coloration due to cone flexing, resulting in less distortion and superior accuracy. For a smoother response and improved durability, the woofer uses a rubber surround.

Tweeters: Each speaker has a 1" C.M.M.D. dome tweeter, which offers superior stiffness and damping compared to traditional metal domes.

Bass Reflex: There is a single port tube opening on the front of each speaker for increased and extended bass response.

5-Way Binding Posts: The gold-plated 5-way binding posts will accept pin connectors, spade connectors, banana plugs, dual banana plugs and bare wire.
