Product Description

Break Your Subwoofer In

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 low pass crossover: 50 – 150 Hz Variable bass boost: 0 – 12 dB, variable input gain control, speaker impedance: 2.6 ohms S/N ratio: 90 dB, frequency response: 30 – 150 Hz

Built-In Amplifier

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.

MOSFET Power Supply

Metal Oxide Semiconductor Field-Effect Transistors quickly switch from full to non-conduction for high efficiency output.

Class A/B

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

Variable low-pass filter gives you control over the frequencies that pass through to the subwoofer.

Variable Bass Boost

Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it.

Phase Control

Phase control lets you switch the speaker phase with the amp if your speakers or subwoofer are hooked up ‘out of phase’.

Short Protection

Automatic shut-off protects the amplifier if it gets too hot or if speakers fail causing a short.

Water Resistance Level: Not Water Resistant
Built-in Amplifier – With a MOSFET power supply you get improved switching speeds, better performance with less power from the driver, lower gate-to-drain feedback capacitance, lower thermal impedance for higher switching frequencies
PWM – Pulse Width Modulated design simplifies power supplies. It controls the output voltage and current precisely by removing the output current sensing loss & eliminating all secondary feedback circuitry. It’s efficient & reliable
Variable Low-Pass Filter – A low-pass filter is an electronic circuit that removes all the notes below the filter’s frequency setting. You will use the Low-pass filter to primarily keep high notes out of your subwoofer(s)
High Level Inputs – Speaker level inputs are commonly referred to as high-level inputs. It will be used to connect the US10 to your factory radio or an aftermarket radio that does not have low-level (RCA) inputs
Low-Level Inputs – Line level inputs, also known as RCA inputs or low-level inputs, use RCA interconnect cables to link the US10 with the source unit. Most aftermarket radios have multiple pairs of RCA outputs that can connect to multiple amplifiers
Variable Bass Boost – Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it
Phase Control – Phase control lets you adjust the speaker phase with the amplifier if your speakers or subwoofer are hooked up “out of phase”
Specs – 12.2” x 8.85” x 2.95”. 8.2 Lbs. LED status indicator. Thermal, short and overload protection circuits. High performance voice coil. Rubber surround. Aluminum cone. The all-in-one combo makes this ideal for spatially challenged vehicles
