Common mistakes to avoid

Where buyers of monitor sub monitors go wrong.

• Mistake

  Adding a sub to a half-treated room

  A sub in a corner of an untreated rectangular room creates a 6–10 dB bass node where you sit. Treat corners first; otherwise the sub makes mixes thinner on consumer systems, not fuller.

• Mistake

  Crossing over too high

  Most main monitors handle down to 50 Hz cleanly. Crossing the sub at 80–100 Hz wastes the mains and muddies the kick. 60–70 Hz is closer to right for most pairs.
