Room acoustics are at least as important as the speakers and deserve equal spending

An untreated domestic room wastes roughly two-thirds of the money spent on speakers by introducing comb-filtering reflections and resonance artifacts. The engineer must address two main problems: (1) early reflections from walls, ceiling, and floor create comb filtering that undermines tonal and level judgments in the midrange; (2) room modes (resonant standing waves between parallel boundaries) cause severe frequency-response peaks and dips at bass frequencies. A typical untreated room renders most low-end judgments unreliable. The professional solution is non-parallel walls, but in practice: acoustic foam at reflection points reduces comb filtering; mineral-fiber bass traps damp room modes; even DIY solutions on small budgets make a meaningful difference.
