- 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.
- 100 watts RMS, 200 watts peak power output
- 8" paper cone driver with rubber surround
- Three input options: dedicated LFE, line level stereo, and speaker level stereo
- Adjustable low-pass filter, volume, and phase controls

Choosing Your Deep Bass Hero: An 8-Inch Subwoofer Buying Guide
An 8-inch subwoofer is a fantastic choice for most home theater setups. It offers a great balance between deep, rumbling bass and a size that fits easily into your living room. Finding the right one means looking closely at a few key areas. This guide will help you pick the perfect speaker to bring movie explosions and music rhythms to life.
Key Features to Look For
When you shop for an 8-inch subwoofer, certain features really matter for sound quality and performance.
Power Handling (Wattage)
This tells you how much power the subwoofer can handle without breaking. Look for the RMS (Root Mean Square) rating. A higher RMS number usually means louder, cleaner bass. For a standard home theater, look for models offering 150 watts RMS or more.
Frequency Response
This shows the range of low notes the speaker can play. Subwoofers focus on the lowest sounds. A good 8-inch model should reach down to about 30Hz or even lower. Lower numbers mean you feel deeper rumbles.
Enclosure Type
Subwoofers come in sealed or ported (vented) boxes. Sealed boxes give tight, accurate bass, great for music. Ported boxes move more air, resulting in louder, deeper “thump” for big movie effects. Choose based on what you watch most often.
Important Materials Matter
The materials used directly affect how the subwoofer sounds and how long it lasts.
The Cone (The Speaker Part That Moves)
Look for cones made of stiff, light materials. Polypropylene or treated paper cones are common. Stiff cones prevent distortion when the speaker moves a lot of air. Heavier, less rigid materials cause muddy sound.
The Surround (The Ring Around the Cone)
The surround connects the cone to the speaker basket. A durable rubber surround allows for long, smooth movement. Foam surrounds can dry out and crack over time, reducing performance.
Factors That Improve or Reduce Quality
Good design makes a big difference in bass quality.
Amplification
Most 8-inch subs are “powered,” meaning they have their own built-in amplifier. Ensure the amplifier matches the speaker. An underpowered amp will strain and distort the sound when you turn up the volume.
Cabinet Construction
A sturdy cabinet reduces unwanted vibrations. Thick, dense MDF (Medium-Density Fiberboard) cabinets sound much better than thin particleboard. Poorly built cabinets vibrate, which colors the sound and makes the bass sound weak.
User Experience and Use Cases
Think about where and how you plan to use your new subwoofer.
- Movie Nights: If explosive action is your priority, choose a ported enclosure with high peak power to deliver those chest-thumping lows.
- Music Listening: If you listen to music often, a sealed enclosure is often preferred. It provides more precise, musical bass that blends well with your main speakers.
- Room Size: An 8-inch sub works best in small to medium-sized rooms (under 300 square feet). In very large rooms, a 10-inch or 12-inch model might be necessary to fill the space with enough bass.
Frequently Asked Questions (FAQ) About 8-Inch Home Theater Subwoofers
Q: Is an 8-inch subwoofer big enough for my home theater?
A: Yes, for small to medium rooms, an 8-inch subwoofer provides excellent, impactful bass. It fits easily without taking up too much space.
Q: What is the difference between a sealed and ported 8-inch subwoofer?
A: A sealed box gives tighter, more accurate bass notes. A ported box uses a vent to move more air, resulting in louder, deeper booming sounds, which many people prefer for action movies.
Q: Should I buy a powered or passive subwoofer?
A: Nearly everyone should buy a powered (active) subwoofer. It has the amplifier built in, making setup much easier. Passive subs require a separate external amplifier.
Q: What RMS wattage should I aim for?
A: Aim for at least 150 watts RMS for a satisfying home theater experience. More power usually means cleaner sound at higher volumes.
Q: How low (in Hz) should the frequency response go?
A: The lower the number, the deeper the bass. Try to find one that reaches 35Hz or lower to ensure you feel the lowest movie effects.
Q: Can I use my 8-inch subwoofer for music as well as movies?
A: Absolutely. A good quality 8-inch sub, especially a sealed model, blends very well with music, adding depth without overwhelming the mix.
Q: What does “Thump” vs. “Rumble” mean when describing bass?
A: “Thump” usually means a fast, punchy bass (good for drums). “Rumble” means a very low, sustained bass sound (great for earthquakes or deep movie effects).
Q: How does cabinet material affect the sound?
A: Thick, dense MDF cabinets stop the box itself from vibrating. Less vibration means you only hear the sound coming from the speaker cone, resulting in cleaner bass.
Q: Do I need to match the subwoofer brand to my main speakers?
A: No, you do not have to match brands. However, you should try to match the *style* of bass. If your main speakers are known for tight sound, pick a sealed sub.
Q: Where is the best place to put the 8-inch subwoofer in my room?
A: Corners often provide the most noticeable bass boost, but they can sometimes sound boomy. Experimenting by placing it near the front wall usually works well for a balanced sound.
