AS-B2.2 utilizes a 6.5” woofer instead of the 5.5” used by the smaller AS-B1.2 and the same 1” Teteron tweeter. The larger enclosure and woofer improves low frequency extension and increases power handling abilities. The bass reflex design takes full advantage of the enclosure size and extracts every bit of efficiency and extension possible for its size. The AS-B2.2 is perfectly at home in music or home theater environments.
