FREQUENTLY ASKED QUESTIONS

What is a subwoofer?

A subwoofer or sub, is a specialised speaker designed to reproduce low-frequency sounds, typically between 20 and 200 Hz. These deep bass sounds are essential for adding depth and realism to music, movies, and games. Without a subwoofer, audio systems often lack the full range of sound, missing the impactful rumble of explosions or the thump of a bassline.

Subwoofer Mistakes!

A few myths often come up around subwoofers:

“They’re only for more bass.” A quality subwoofer adds detail and balance, not just volume.

“One big sub is enough.” In most rooms, two or more smaller subs deliver smoother, more consistent bass.

“Music doesn’t need a subwoofer.” A well-integrated sub reveals low-end detail in all kinds of music, not just movies.

“Placement doesn’t matter.” Subwoofer position is critical – the wrong location can make bass unbalanced or boomy.

How many subwoofers do I need in my room?

One subwoofer can add plenty of bass, but using two or more often gives a smoother, more balanced result. Multiple subs help spread bass evenly, reducing “boomy” peak areas, or “null” areas where bass disappears altogether.

The right number depends on your room size, shape, and performance goals. Smaller spaces may do well with a single sub, while larger or dedicated cinema rooms benefit from dual or even four-sub setups.

At Hifi Hunter, we design subwoofer systems tailored to your room so you get deep, consistent bass wherever you sit.

How do I choose the right size subwoofer for my room?

The ideal subwoofer depends on your room size, layout, and how you plan to use the system. However larger rooms generally need bigger drivers or multiple subwoofers to deliver even, powerful bass. The general rule is bigger and power powerful is better – you can’t cheat physics. Smaller spaces can achieve great results with more compact models, especially when carefully placed.

It’s not just about size – room acoustics and system design matter just as much.

At Hifi Hunter, we assess your space and recommend the right subwoofer setup so you get deep, controlled bass without overwhelm.
