Overview
Key Features
This is an 8" powered subwoofer capable of producing 60 watts (RMS) output. The subwoofer has a frequency response range of 50 to 250 Hz with a lowpass crossover filter, which can be adjusted from 50 to 150 Hz. Gain and frequency knobs on the control panel allow you to adjust the crossover filter and the power output for the optimum blend and balance of bass output with your stereo or surround speakers.Waterproof : No
The subwoofer has multiple input options, which allow it to be used with any existing stereo or 5.1 (or greater) amplifier system. For each input there is a corresponding output.
High-level inputs accept a full-range signal from the amplifier's stereo speaker outputs. When connecting the unit as part of a 5.1 system, these would be taken off the Front Left and Front Right outputs in parallel to the standard pair of front speakers. The subwoofer provides its own power and includes impedance matching circuitry, so this will not reduce the power output to the front speakers or affect the overall impedance load on the amplifier.
Additionally, the subwoofer has a set of right/left Line Level inputs. If using a standard stereo system, without a special subwoofer output, you can connect these to the left and right line level outputs on the amp. The subwoofer will then combine the signals to process the mono bass signal it needs to drive the speaker. If you are using an amplifier with a single mono subwoofer line level output, simply use an RCA "Y" cable to split the output and send it to the two line level inputs on the subwoofer.
The subwoofer is housed in an attractive black wood cabinet that measures 13.75" x 11.75" x 11.75" (H x W x D). The driver and a 2 3/4" sound port are located on the front, covered by a black cloth speaker grill.

Pros & Cons
👍 Pros
- Built-in amplifier eliminates the need for a separate external amp
- Multiple input options (high-level and line-level) ensure compatibility with virtually any receiver or amplifier
- Adjustable crossover and gain knobs let you fine-tune bass output to match your room and speakers
- Compact 13.75" x 11.75" x 11.75" cabinet fits easily in tight spaces
- Corresponding outputs for each input allow pass-through signal routing
👎 Cons
- 60-watt RMS output may not fill larger rooms with sufficient bass impact
- Frequency response starts at 50 Hz, which misses the deepest sub-bass content below that threshold
- 8-inch driver is modest in size and may struggle to deliver visceral impact at higher volumes
- No wireless connectivity — all connections are wired only
Frequently Asked Questions
Does the Monoprice 108248 subwoofer require a separate amplifier?
No, this is a powered (active) subwoofer with a built-in 60-watt RMS amplifier, so it does not need an external amp to operate.
How do I connect this subwoofer to a stereo receiver that has no dedicated subwoofer output?
You can use either the high-level speaker wire inputs (connected in parallel to your front speakers) or the left/right line-level RCA inputs from your receiver's line-level outputs. Both methods work without affecting power to your main speakers.
What does the adjustable crossover filter do on this subwoofer?
The lowpass crossover knob lets you set the cutoff frequency between 50 Hz and 150 Hz, controlling which bass frequencies the subwoofer reproduces so it blends smoothly with your main speakers.
How large is the Monoprice 108248 subwoofer?
The cabinet measures 13.75" high x 11.75" wide x 11.75" deep, making it compact enough to fit beside furniture or in a corner.
