Overview

The Monoprice 115698 6.5" Fiber In-Wall Subwoofer is designed for homeowners who want impactful bass without a bulky enclosure taking up floor space. Its aramid fiber cone — made from materials similar to DuPont Kevlar — is stiffer and more resilient than standard polymer drivers, which translates to tighter bass response and less distortion at higher volumes. With a 300-watt peak power rating, it can fill a mid-sized room with satisfying low-end without breaking a sweat.

Installation is straightforward thanks to the included instructions, and the subwoofer fits into walls with as little as 3.6 inches of depth behind the surface. Once mounted, the removable, paintable grille lets it blend into virtually any room. Whether you are building out a dedicated home theater or upgrading your living room's audio, this in-wall subwoofer offers a compelling balance of performance, aesthetics, and affordability — though you will need a separate amplifier to drive it.

Key Features

Easy Installation: The subwoofer includes easy-to-follow installation instructions. You can install it into almost any wall with at least 3.6in of space behind the wall.

Aramid Fiber: The Aramid Fiber driver uses materials similar to what is used in DuPont Kevlar fiber products. The sturdy construction holds its form better than polymers, which minimizes distortion.

300W Peak Power: The 300 watt peak power capacity means that you can fill your room with deep, earth-shattering bass.

Paintable Grill: The paintable grill allows you to match the color of your walls to make the speaker virtually invisible.

Looks Good, Sounds Good: The combination of the low profile, in-wall design and the powerful subwoofer itself make for an excellent addition to a standard home theatre.

Pros & Cons

👍 Pros

  • Aramid fiber driver minimizes distortion and maintains cone shape under heavy use
  • In-wall design keeps it completely out of sight for a clean, uncluttered room
  • Paintable grille lets you match any wall color for near-invisible installation
  • 300W peak power delivers surprisingly deep bass from a compact in-wall form factor
  • Requires only 3.6 inches of behind-wall depth, fitting in most standard wall cavities

👎 Cons

  • Sold individually, so outfitting a room with multiple units increases cost
  • In-wall installation is permanent and requires cutting into drywall
  • 6.5-inch driver size limits the lowest bass frequencies compared to larger freestanding subwoofers
  • No built-in amplification, so a separate amplifier or compatible receiver is required
