We build the AV 30s with the same quality materials and precision electronics as our acclaimed M-Audio professional studio speakers. The audiophile-grade Class A/B amplifier architecture, ferrofluid-cooled silk cone tweeters, polypropylene-coated woofers, and dense wooden enclosures add up to big, defined sound that defies the speakers' small size. Clear, cohesive sound The AV 30 speakers use proprietary OptImage wave guide technology—originally developed for the professional M-Audio speaker line—to deliver superior clarity and detail. Each speaker also features a precision-engineered crossover, which ensures that the sound emanating from the low-frequency driver will blend seamlessly with the sound from the high-frequency driver—so those deep lows transition smoothly into crystal-clear highs. Extended low end If you crave bass, the AV 30s have you covered. With wooden cabinets and bass reflex design, the AV 30s kick out serious low frequencies—perfect for producing hip-hop and electronic music, or enjoying your favorite CDs, MP3s, DVDs, and games.
