## Description

The Krown Bass Master CBT-8US powered subwoofer pumps out lush, car-rocking bass through a design so cool you won't want to hide it in your trunk. The patented slim port design delivers deep bottom end while minimizing turbulence. Turbulence, or port noise at high volume, isn't just annoying; it's a signal that the port is no longer working and you're getting less bass than you paid for. The slim design is carefully optimised for the combination of woofer, amp and enclosure, and no other company has it. Now we assure that only time you'll need to stop is for gas. FEATURES: P.W.M Mosfet Power Supply RCA Input /High Level Input Phase Switch (0 or 180 Degree) Bass Boost 0- 12 dB @ 45 Hz Sub Sonic Filter (20-50 Hz) LPF Filter (50-150 Hz) Low Level Input High Level Input Protection Circuit: Thermal Protection Circuit Short Protection Circuit Over load Protection Circuit Amplifier: 65W RMS @4 ohm @100 Hz Slim woofer: 8", 4 ohms
