Resonances are the primary problem in loudspeakers

Evidence

Hearing bass is advantageous, so exaggerated room resonances can benefit a loudspeaker with deficient bass output, even if the combined bass is colored. Some contemporary music styles, studio recordings, demand substantial bass output. Inadequate bass will be criticized and excessive bass rewarded. — Toole, Floyd E, Sound reproduction- the acoustics and…, 549 (#qualifies, via linked claim)
