Overview: The Infinity Beta 40 is a 3-way, dual 6-1/2"
floor-standing loudspeaker featuring Infinity's patented CMMD drivers.
Ceramic Metal Matrix Diaphragm
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 dual 6-1/2" C.M.M.D. cone woofers virtually eliminate coloration due to
cone flexing, resulting in less distortion and superior accuracy. For a smoother
response and improved durability, each woofer uses a rubber surround.
Midranges: The speaker use a
5" C.M.M.D. cone midrange for increased vocal and midrange clarity.
Tweeters: Each speaker has a 1"
C.M.M.D. dome tweeter, which offers superior stiffness and damping compared to
traditional metal domes.
Constant Acoustical Impedance
Waveguide (CAI): The 1" C.M.M.D dome tweeters are mounted in a Constant
Acoustical Impedance Waveguide for improved high-frequency dispersion anywhere
in your listening room. The CAI Waveguide design is ideal for both stereo or
Bass Reflex: There
is a single
port tube opening on the rear of
each speaker's rigid, well-braced enclosure for increased and extended bass response.
Generally, bass output will increase as the speaker is moved closer to a wall or
corner due to its rear port.
Binding Posts: Each speaker has two sets of
gold-plated 5-way binding posts connected by gold-plated jumpers. By removing
the jumpers, you can separately use the two sets of binding posts to bi-amp or
bi-wire the speakers. Bi-wiring will improve resolution and dynamics. For even
greater improvement, you can use two amplifiers (bi-amping).
Rubber and Spiked Feet:
The speakers feature four non-removable rubber feet that enable the speakers to
be placed on a smooth-surfaced floor, such as tile or hardwood. Each
speaker also comes with 4 metal spiked feet. The spikes can be used to stabilize the speakers
to floor surfaces such as carpet, and they help provide better defined bass response by coupling the speakers to the floor. The spiked feet screw
into threaded sockets on the bottom of the cabinet's rubber feet. The spikes add
a half inch to the speaker's overall
Magnetically Shielded: The Beta
40 speakers are magnetically shielded for safe placement adjacent to your
