No. 2
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 Awesome Sound: Choosing an 8-Inch Home Theater Subwoofer

Want to feel the rumble of explosions in movies or the deep beat of your favorite songs? An 8-inch subwoofer is your ticket to a richer home theater experience. This guide will help you pick the perfect one.

1. Key Features to Look For

Power (Wattage)

More watts usually mean a louder and more powerful sound. For an 8-inch subwoofer, look for at least 100 watts for a good punch. Higher wattage can fill bigger rooms better.

Frequency Response

This tells you how low the subwoofer can go. A good range for an 8-inch might be from 30Hz to 200Hz. The lower the number, the deeper the bass you’ll hear. Think of it as the “deepness” of the sound.

Driver Size and Type

You’re looking at an 8-inch driver, which is a good size for many rooms. Drivers can be front-firing or down-firing. Front-firing speakers send sound directly at you. Down-firing speakers bounce sound off the floor, which can give a more spread-out bass effect.

Connectivity

Make sure the subwoofer can connect to your home theater receiver. Most have RCA inputs. Some also offer wireless options, which means fewer messy wires!

Adjustments

Look for controls like a volume knob and a crossover frequency dial. The volume control lets you match the subwoofer’s loudness to your other speakers. The crossover lets you set which sounds the subwoofer handles. This helps blend the bass smoothly.

2. Important Materials

Cabinet Construction

The box (cabinet) matters a lot. A sturdy cabinet made of thick MDF (medium-density fiberboard) is best. It stops vibrations and makes the bass sound cleaner. Cheaper materials can make the sound muddy.

Driver Material

The cone of the speaker driver is often made of paper, polypropylene, or a mix. These materials are chosen to be light yet strong, which helps them move quickly and create clear bass.

3. Factors That Improve or Reduce Quality

Build Quality

A well-built subwoofer feels solid. Check for tight seams and good finishing. A wobbly or poorly made cabinet will hurt sound quality.

Port Design

Many subwoofers have a port (a hole in the cabinet). A well-designed port helps the subwoofer produce deeper bass. A poorly designed port can create unwanted noise or “chuffing” sounds.

Amplifier Type

Subwoofers have a built-in amplifier. Class D amplifiers are common because they are efficient and don’t get too hot. A good amplifier makes sure the subwoofer has enough power to sound its best.

4. User Experience and Use Cases

For Movies and TV Shows

An 8-inch subwoofer adds a huge impact to action movies. You’ll feel the rumble of engines, the crash of thunder, and the boom of explosions. It makes watching movies much more exciting.

For Music

While larger subwoofers might be better for very deep bass in music, an 8-inch can still add a nice warmth and punch to your favorite songs. It’s great for genres with a strong beat, like hip-hop or electronic music.

Room Size

An 8-inch subwoofer is ideal for small to medium-sized rooms. It provides enough bass without overwhelming the space. In larger rooms, you might want to consider a 10-inch or 12-inch subwoofer.

Placement

Where you put your subwoofer can make a big difference. Experiment with different spots in your room. Often, placing it in a corner can boost the bass output.

Frequently Asked Questions (FAQ)
