Compact 8-inch powered subwoofer

The Monoprice 144514 is an 8-inch 100-Watt powered subwoofer designed for home audio systems needing low-frequency reinforcement without a large footprint. Its ported enclosure is engineered to deliver ample bass output while remaining small enough to avoid dominating the room or décor.

Flexible placement and connection options

The compact dimensions allow placement in corners, beside a sofa, or near a TV stand where larger cabinets would not fit. Hook-up uses either RCA line-level inputs or high-level speaker inputs, so it integrates with both dedicated subwoofer outputs and amplifier speaker terminals without extra adapters.

Adjustable output with standard controls

Volume, crossover, and phase controls sit on the rear panel for tuning the subwoofer to the listening position and main speakers. The built-in 100-Watt amplifier drives the 8-inch driver within the ported enclosure, providing bass extension for music and movies in typical living-room listening scenarios.

Questions about this item

At what point does the 100-watt amplifier hit its limit during long listening sessions?

The built-in 100-watt amplifier will reach its maximum output when the driver can no longer move cleanly, which you hear as compression or distortion at very high volumes.

How much heat or fan noise does the subwoofer produce after running all day?

The compact ported enclosure relies on passive cooling, so it stays warm but silent; no internal fan means zero mechanical noise during extended use.

Which existing speaker connections do I need on my amplifier or receiver to use the high-level inputs?

You need standard speaker-level output terminals (left and right) on your amp or receiver to connect the subwoofer's high-level speaker inputs.
