When people think about great sound, they usually focus on clarity and detail. But there’s one part of the experience that makes everything feel real: the subwoofer.

A subwoofer gives your system depth, power, and emotion. It’s what makes explosions rumble during a movie and bass lines hit with energy. Whether you’re upgrading your stereo or building a full home theater, a subwoofer brings your system to life.

What Is a Subwoofer?

A subwoofer is a specialized speaker that reproduces low frequencies, typically between 20Hz and 100Hz. These are the deep bass notes that you feel more than you hear.

Your main speakers handle most of the sound, but they often can’t produce those low, room-filling tones. A subwoofer fills that gap, creating a sense of fullness and realism. When properly integrated, it blends seamlessly into your system and simply makes everything sound more natural.

Why You Need a Subwoofer

• • Movies Feel Cinematic: Explosions shake the room, car chases feel more intense, and sound effects have real impact.
• • Music Sounds Fuller: Kick drums feel tight, bass guitars have texture, and every song gains new dimension.
• • Your Speakers Perform Better: By handling the heavy lifting, the subwoofer lets your main speakers focus on mids and highs, improving clarity across the board.

Choosing the Right Size and Power

• • 8" to 10": Ideal for small rooms or setups where space is limited.
• • 12": The most versatile size, offering deep, accurate bass for most systems.
• • 15" or larger: Perfect for large rooms or listeners who crave big, thunderous sound.

Most subwoofers today are powered models, which include a built-in amplifier. This design makes setup simple and ensures the sub has plenty of clean power. Passive subwoofers, which require an external amp, are less common for home use.

Sealed vs. Ported Subwoofers

• • Sealed Subwoofers: Tight, controlled bass with great accuracy. A favorite for music-focused systems and smaller rooms.
• • Ported Subwoofers: Louder, deeper bass that extends lower in frequency. Excellent for home theaters or larger rooms.

Placement Tips

• • Start with the subwoofer near the front of the room, between your front speakers.
• • Avoid placing it directly in a corner, which can cause bass to sound “boomy.”
• • Try the subwoofer crawl: place the sub where you normally sit, play a bass-heavy track, and walk around the room. When you find the spot where the bass sounds smooth and even, that’s often the best location.
• • For larger spaces, consider using two subwoofers to achieve more balanced bass coverage.

Connecting Your Subwoofer

• • Home Theater Systems: Use the “Sub Out” or “LFE” output on your AV receiver and connect with an RCA or XLR cable.
• Stereo Systems: If your amp doesn’t have a dedicated sub output, use the subwoofer’s speaker-level inputs.
• Wireless Option: With accessories like the Emotiva VSUB Wireless Kit, you can connect your subwoofer without running long cables.

How to Choose the Right Subwoofer

• • Room Size: Larger rooms need larger drivers or more power.
• • Listening Style: Movie fans often prefer ported subs for deeper rumble, while music lovers might lean toward sealed designs for accuracy.
• • Budget: Great bass doesn’t need to be expensive. Emotiva designs products that deliver high-end performance without high-end prices.
