Much like the engine of a new automobile, a new subwoofer must go through a short but important process of "break-in" before it is run under harsh conditions. The "break-in" process will ensure the subwoofer is able to perform as it has been designed to. This process involves subjecting the subwoofer to no more than low-to-medium volume levels for a number of hours in the enclosure.

3-4 hours is generally sufficient for the subwoofer's suspension to loosen enough to prevent the voice coil(s) from overheating and causing failure. The break-in period is also effective in extending subwoofer life. Over-driving the woofer before it has been properly broken-in will usually result in premature failure and poor performance. 10-inch subwoofer, Built-in class A/B amplifier, MOSFET power supply. Soft turn-on circuit, RCA (low) & speaker (high) level inputs.

Thermal, short and overload protection circuit. Green LED power status indicator, red LED protection status indicator. Subwoofer level control, switchable phase shift selector switch: 0 or 180º. Variable subsonic filter: 20 - 200 Hz, variable low pass crossover: 50 - 150 Hz. Variable bass boost, variable input gain control, speaker impedance: 2.6 ohms.

S/N ratio: 98 dB, frequency response: 15 - 120 Hz. Systems with a built-in amplifier do not require the addition of an external amp.

They already have the power to play louder. High and Low Level Inputs. High-level inputs accept speaker output signals and low-level inputs accept pre-amp output signals to allow for the addition of amps and processors to standard factory or aftermarket source units.

Metal Oxide Semiconductor Field-Effect Transistors quickly switch from full to non-conduction for high efficiency output. Our Class-A/B amplifiers feature specific linear circuitry that increases sound quality and power output while reducing distortion and improving efficiency.

Variable low-pass filter gives you control over the frequencies that pass through to the subwoofer. Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it. Phase control lets you switch the speaker phase with the amp if your speakers or subwoofer are hooked up "out of phase". Automatic shut-off protects the amplifier if it gets too hot or if speakers fail causing a short.
