The Ultimate Buying Guide for Subwoofers with Built-In Amps
Choosing the right powered subwoofer can really shake up your home audio. A powered subwoofer, which means it has its own amplifier built right in, is easier to set up than separate components. This guide helps you pick the best one for your needs.
Key Features to Look For
When shopping, you need to check a few important features. These elements decide how loud and clear your bass will sound.
Power Handling (Wattage)
This tells you how much power the amp can push. More watts usually mean louder, deeper bass. For a small room, 100 to 150 watts might be enough. For a large living room or home theater, look for 200 watts or more.
Driver Size
The driver is the actual speaker cone that moves the air. Common sizes are 8-inch, 10-inch, and 12-inch. Bigger drivers (like 12-inch) can move more air, giving you deeper, rumbling bass. Smaller drivers are great for tight, quick bass notes in smaller spaces.
Frequency Response
This shows the range of low notes the subwoofer can play. You want a low number here, like 20Hz (Hertz). A lower number means you can feel those super low movie explosions or deep music notes.
Enclosure Type
Powered subwoofers usually come in two main types:
- Sealed Enclosure: These boxes are completely airtight. They give you very tight, accurate, and musical bass. They might not be as loud as ported ones.
- Ported (or Vented) Enclosure: These boxes have a hole or tube (port). This design lets them play louder and hit deeper bass notes, often better for action movies.
Important Materials and Build Quality
The quality of the parts matters a lot for sound and durability.
Driver Cone Material
The cone material affects how fast the speaker reacts. Paper cones are common and sound natural. Polypropylene cones resist moisture and are very durable. Some high-end subs use materials like aluminum or treated composites for very stiff, fast movement.
Cabinet Construction
Look for cabinets made from thick Medium Density Fiberboard (MDF). MDF absorbs vibrations better than thin wood or plastic. A heavy, solid cabinet reduces unwanted buzzing and rattling, making the bass sound cleaner.
Factors That Improve or Reduce Quality
Good features improve your experience; bad ones hurt it.
Quality Enhancers
- Adjustable Crossover: This lets you set the exact low-frequency point where the subwoofer takes over from your main speakers. This blending is crucial for good sound.
- Phase Switch (0 or 180 degrees): This helps the subwoofer sound correct with your main speakers, especially if they are placed far apart.
- Auto On/Off Feature: The sub turns on when it senses a signal and goes to sleep when silent, saving energy.
Quality Reducers
- Cheap Amplifier Class: Low-quality built-in amps can distort the sound when you turn the volume up high.
- Thin Cabinet Walls: Thin walls vibrate easily, coloring the sound and making it sound muddy instead of clear.
User Experience and Use Cases
Think about where and how you will use your new sub.
Home Theater Use
If you love watching movies, prioritize power (wattage) and deep extension (low frequency response). A ported, powerful 12-inch sub often works best here to handle those big LFE (Low-Frequency Effects) sounds.
Music Listening
For music lovers, accuracy is key. Sealed enclosures with stiff cones are often preferred because they reproduce bass notes precisely. You need good crossover controls to blend the sub seamlessly with your existing bookshelf or tower speakers.
Setup Ease
Since the amp is built-in, setup is simple. You usually only need one RCA cable from your receiver or amplifier to the subwoofer, plus the power cord. Powered subs are generally plug-and-play.
10 Frequently Asked Questions (FAQ) About Powered Subwoofers
Q: What is the main difference between a powered and an unpowered subwoofer?
A: A powered subwoofer has an amplifier built inside the box. An unpowered subwoofer needs a separate external amplifier to work.
Q: Do I need a powerful receiver if I buy a powered subwoofer?
A: No. Since the powered sub has its own amp, your receiver only needs to send a low-level signal to it. You do not need high power output from the receiver for the sub.
Q: What does “Ported vs. Sealed” really mean for sound?
A: Sealed subs give tight, accurate bass. Ported subs give louder, deeper, rumbling bass, which is great for movies.
Q: How do I connect a powered subwoofer to my stereo system?
A: Most people connect it using an RCA cable from the receiver’s “Sub Out” or “LFE Out” jack directly to the powered sub’s input.
Q: What is the Crossover setting, and why is it important?
A: The crossover sets the highest frequency the subwoofer will play. Setting it correctly ensures the subwoofer blends smoothly with your smaller speakers.
Q: Should I worry about the subwoofer matching my main speakers?
A: Yes. If your main speakers only go down to 60Hz, you should set the sub’s crossover slightly above that, maybe 70Hz or 80Hz, so the sub handles the lowest sounds.
Q: What does the Phase switch do?
A: The phase switch adjusts the timing of the subwoofer’s sound wave compared to your main speakers. You flip it to 0 or 180 degrees to make sure the bass hits your ears at the right time, sounding louder and fuller.
Q: Is a 10-inch sub always better than an 8-inch sub?
A: Not always. A high-quality 10-inch sub will likely outperform a cheap 12-inch sub. Generally, bigger subs can play lower notes, but size isn’t the only factor.
Q: How much space do I need around the subwoofer?
A: You should keep the rear or side ports (if it has one) free from walls, usually at least 6 to 12 inches away, to let the air move freely.
Q: Can I use a powered subwoofer for music and movies equally well?
A: Yes, many modern powered subs handle both tasks well. Look for models that have good controls, allowing you to dial in tight bass for music and powerful output for movies.
