CMMD Sound
Beta 20's 6 ½" woofer and 1" tweeter both feature the revolutionary Ceramic Metal Matrix Diaphragm (CMMD) technology developed for the premium Prelude Series. (CMMD) technology is not used in the newer Primus or Cascade Series speakers.
High Frequency Response Beyond 40,000Hz
Beta Series speakers feature Infinity's patent-pending Constant Acoustic Impedance (CAI) waveguide technology, which significantly enhances performance over other waveguide designs. CAI high-frequency drivers display increased sensitivity, creating more dynamic headroom and enabling seamless sonic transition between the tweeter and lower frequency transducers in both two-way and three-way systems. All of this helps assure uniform frequency response across the entire listening room, greatly expanding the optimum listening area. With CAI, the full potential of CMMD tweeters is realized, extending the frequency response beyond 40kHz and yielding exceptional fidelity, especially with today's demanding high-resolution, digital sources like SACD and DVD-Audio. CAI waveguides also allow for less complex crossover circuitry, resulting in a distinctly pure, accurate sound unique to Infinity Beta.
Sandwich For Good Sound
Infinity engineers invented and patented Ceramic Metal Matrix Diaphragm (CMMD) transducer material, a sandwich made up of layers of ceramic alumina (20% of the total thickness top and bottom) anodized to a metallic aluminum core (the remaining 60% of total thickness). Among the stiffest materials known, alumina and aluminum were chosen because sound moves through them faster than through conventional transducer materials and the CMMD sandwich responds to electrical signals very rapidly without coloring the sound at all. That's why every transducer in Beta Series speakers incorporates CMMD technology.
Infinity's CMMD technology is patented (nos. 6,327,372 and 6,404,897), so when other manufacturers claim that their transducers are ceramically coated, it's merely a cosmetic surface treatment. Beta Series transducers are made with 20/60/20% alumina-aluminum sandwich material first and foremost for the sound, not just the look.
Cabinet Resonances Neutralized
Infinity engineers use data from a scanning laser vibrometer to anaylze cabinet resonances and design effective bracing to neutralize them. Beta Series' ultrathick, contoured baffles provide a rigid, stable platform for the drivers while at the same time minimizing unwanted baffle-edge diffractions. The only sound you hear from a Beta 20 speakers comes from drivers, not the enclosure.
