M&K Sound bowed 10-, 12- and 15-inch THX-certified subwoofers in the X+ Series line. The 700-watt X15+ ($5,999) is certified in the THX Dominus class, whether used as a single subwoofer or in a pair; the 600-watt X12+ ($4,999) is certified Ultra; and the 500-watt X10+ ($4,499) is certified THX Select, said the company Tuesday.
