購入ガイド: 400w Enclosed Subwoofer Systems
📋 目次
1Is 400W RMS or peak power more important for real performance?
Focus on RMS (root mean square) wattage, not peak — 400W RMS delivers consistent, deep bass, while peak power is a short-term burst. A 400W RMS enclosed subwoofer system ensures reliable, distortion-free output during extended listening sessions.
2What enclosure type is best for a 400W subwoofer system?
Sealed enclosures offer tighter, more accurate bass and are ideal for smaller spaces, while ported (vented) boxes boost low-end output for larger rooms. For 400W systems, ported designs often maximize efficiency and volume without overworking the driver.
3What driver size should I look for with a 400W system?
12-inch drivers are common for 400W systems, balancing power handling, cone movement, and room-filling bass. 15-inch drivers offer more output and depth but require more space and are better for dedicated listening areas or vehicles with large trunks.
4Do I need a built-in amplifier or separate amp for a 400W subwoofer?
Most 400W enclosed subwoofer systems include a built-in amp, which is convenient and space-efficient. If you want more control or higher output, a separate amp can better match the sub’s power needs and improve sound quality, especially in car audio setups.
5What kind of crossover settings should I look for?
A built-in adjustable crossover (typically 50-200Hz) lets you fine-tune bass integration with your main speakers. Look for a high-pass and low-pass filter with slope options (e.g., 12dB or 24dB per octave) to avoid muddiness and ensure clean, layered sound.
