Monoprice 60-Watt Powered Subwoofer - 8 Inch With Auto-On Function, For Studio And Home Theater Black
  • 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.

Your Guide to the Perfect 8-Inch Home Theater Subwoofer

Are you ready to feel the rumble? An 8-inch subwoofer can transform your home theater experience, adding that deep, powerful bass that makes movies and music truly come alive. But with so many options, how do you pick the right one? This guide will help you find the perfect 8-inch subwoofer for your setup.

1. Key Features to Look For

Power (Wattage):

This tells you how loud the subwoofer can get. More watts usually mean a more powerful and impactful sound. For most living rooms, 100-200 watts is a great starting point. For larger rooms or if you like it loud, look for 200 watts or more.

Frequency Response:

This shows the range of low sounds the subwoofer can produce. A lower number means it can hit those really deep bass notes. Aim for a subwoofer that goes down to at least 30Hz (Hertz) for that satisfying boom.

Ported vs. Sealed Enclosure:
Ported:

These have a hole (port) that helps boost the bass. They often sound louder and punchier, which is great for action movies. However, they can sometimes be a bit less precise.

Sealed:

These have a completely enclosed box. They tend to offer tighter, more accurate bass. This is often preferred for music or if you want a more refined sound.

Connectivity:

Check how the subwoofer connects to your receiver. Most use an RCA cable. Some might have speaker-level inputs if your receiver doesn’t have a dedicated subwoofer output.

2. Important Materials

Driver Material:

The “driver” is the part that makes the sound. Common materials include paper, polypropylene, and treated wood pulp. High-quality materials help produce cleaner, more detailed bass. A cone that is stiff but light is usually best.

Enclosure Material:

The box the driver sits in is just as important. MDF (Medium-Density Fiberboard) is a popular choice because it’s dense and doesn’t vibrate much. This prevents unwanted buzzes and rattles, keeping your bass clean.

3. Factors That Improve or Reduce Quality

Amplifier Quality:

The amplifier built into the subwoofer powers the driver. A good amplifier delivers clean power without distortion, even at higher volumes. Cheaper amps can sound muddy or weak.

Cabinet Construction:

A well-built cabinet is crucial. Look for sturdy construction with good bracing inside. This reduces vibrations and makes the bass sound more controlled and accurate. Poorly built cabinets can make the subwoofer sound boomy and unfocused.

Driver Design:

The design of the driver itself matters. Features like a robust surround (the flexible edge of the cone) and a strong magnet help the driver move more air and produce deeper, more powerful bass.

4. User Experience and Use Cases

An 8-inch subwoofer is perfect for smaller to medium-sized rooms. It’s ideal for enhancing movie nights, making explosions rumble and soundtracks soar. Gamers will love the added impact it brings to their gaming worlds.

For music lovers, a good 8-inch subwoofer can add depth and richness to your favorite tracks, especially in genres like hip-hop, electronic, or rock. It fills out the sound and makes the listening experience more immersive.

Setting up is usually straightforward. You’ll connect it to your AV receiver and then place it in a good spot in your room. Experimenting with placement can make a big difference in how the bass sounds.
