Featuring a polished, piano-quality black finish, the MX5021 delivers big time in a powered audio system that not only sounds great - but looks terrific in your home or office. Two midrange drivers in each satellite produce extremely responsive sound, while the horn-loaded tweeter offers extra-wide dispersion of those crystal-clear highs. Not to be outdone, the woofer pumps out deep lows you'll feel in your bones. Add in THX certification for cinema-quality sound, and you've got an excellent alternative to a high-end audio system.
