Frequently Asked Questions
How much RMS power do I need in a subwoofer?
For a small room (under 2,000 cubic feet), 200-300W RMS is sufficient. Medium rooms (2,000-4,000 cu ft) benefit from 300-500W. Large dedicated theaters may need 500W+ or dual subwoofers for even bass distribution.
Sealed vs ported subwoofer: which is better?
Sealed subwoofers offer tighter, more accurate bass and are easier to integrate with room correction. Ported subs play louder and dig deeper for the same driver size but can sound less controlled. For music-focused listening, sealed is often preferred. For home theater impact, ported excels.
Do I need one or two subwoofers?
A single sub can sound great, but dual subs dramatically improve bass evenness throughout the room by reducing room mode peaks and nulls. If budget allows, two smaller subs typically outperform one larger sub in overall room coverage.
What frequency extension should I look for?
For home theater, look for -3dB extension at 25 Hz or lower to capture the deepest movie effects. Music-focused listeners can get by with 30-35 Hz extension. The deepest movie content goes down to 20 Hz or below.
