    Product Description

    The Monoprice CSW‑8 is an 8” 100W powered compact subwoofer that is small enough to not dominate the room and still has ample bass output. This diminutive, ported subwoofer can be placed anywhere in your room without taking up a lot of square footage—in the corner, beside your sofa or TV stand—and not have it dominate your décor. Hook-up is a breeze through the RCA inputs or high-level speaker inputs and easily set your output with the volume, crossover, and phase controls. Fortunately, you will not have to skimp on bass output, as the CSW‑8 has been specifically engineered to take advantage of its compact enclosure.

    Reviewed in the United States on May 1, 2024
    I had been looking for a compact subwoofer to fit inside my entertainment stand, which I know might not be everyone's preferred sub placement, but my space is limited regardless. Most of the options I found that would fit were cube shaped 6-6.5" drivers and I wanted a little more punch. Turning this unit on its side so the driver is down firing made it fit perfectly. I added rubber feet + foam pads to the included feet which gives it nearly an inch of clearance.
    The sound fills in the low end of my Kanto Yu speakers perfectly, and can shake the floor at higher volumes without noticable distortion. I had to turn the volume knob a little higher than expected to get things audible. The auto power feature works perfectly. Also I did not see it mentioned on any product pages but this did come with a stereo RCA cable.
    I highly recommend this subwoofer! I think it would pair great with any set of bookshelf monitors with a sub out. If you have beefier speakers I'm sure the 10" version is even better.
    Reviewed in the United States on April 10, 2024
    for the low price of this sub it blows away sub costing much more money.the frequency response is great and the bsss is tight.the auto off feature after 2 minutes of no signal is a plus.just place it in a corner and enjoy the experience of good tight bass.
    Reviewed in the United States on March 1, 2024
    I've had other Monoprice subwoofers in the past that work awesome. Needed another one for a different setup; works great!
