The OW42-M features a proprietary, high-excursion 4" woofer to provide bass down to 100 Hz and 1" Titanium tweeter for smooth response to 22kHz. A James designed network provides a seamless transition between the woofer and tweeter for excellent on and off axis performance. The OW42-M is constructed of aircraft aluminum and includes an aluminum perforated grille to provide years of trouble free use. The OW42-M makes an excellent addition to the SPL3 series of LED TV speakers as a matching surround speaker. It also can be used as a standalone on-wall or bookshelf with or without a companion James subwoofer.
