How many acoustic panels do I need?

A general rule: cover 15-30% of wall/ceiling surface area. For a 200 sq ft room, use 30-60 sq ft of panels. Focus on first reflection points (mirror test), corners (bass traps), and parallel walls to reduce flutter echo.

Where should I place acoustic panels?

Priority order: 1) Behind speakers (5-10 panels), 2) First reflection points on side walls, 3) Ceiling above listening position, 4) Rear wall corners (bass traps). Use the mirror trick—sit at listening position; where you see speakers in a mirror = panel placement.

🎯 Acoustic Treatment Guide

The 20-30% Rule: Cover 20-30% of wall/ceiling surface with absorption. Too much creates a "dead" room; too little leaves echo.

First Reflection Points: Use the mirror trick—sit at your listening spot. Have someone move a mirror along the side walls. Where you see the speakers = place panels.

Bass Traps Are Essential: Low frequencies gather in corners. Place thick panels (4-6 inches) in ceiling corners and floor tri-corners for bass control.

Common Mistake: Don't just cover the wall behind speakers! Focus on side walls and ceiling first reflection points—that's where most problems occur.

Panel Thickness: 2" panels = 250Hz+, 4" panels = 125Hz+, 6" corner traps = 80Hz+. Thicker is better for low frequencies.
