The Alto Professional TX18S is an 18-inch powered subwoofer that adds deep, powerful bass to your PA system. With 900W peak Class-D amplification and a high-output woofer featuring a 3-inch voice coil, it suits DJ sets, live performances, rehearsal studios and venue installations.
Built-in DSP provides EQ and protection, while Music and Live voicings let you tailor the bass to your application. Selectable 80 Hz, 100 Hz and 120 Hz low-pass filter settings help match the subwoofer with your main speakers. Polarity reversal provides another adjustment when combining speakers.
The internally braced MDF cabinet features a front-ported design, protective metal grille and durable textured finish. Two side handles assist with transport, while a 36 mm pole socket supports compatible speaker mounting. Shop the Alto Professional TX18S at TOFTrading in Egypt.
