Small-room acoustics constrain bass quality below the Schroeder transition frequency.

Evidence

Deep, clean, tight bass is universally desirable but very often prevented by the small rooms in which we listen—all of which are different in structure and in arrangements of loudspeakers and listeners. Section 5.1 explains the distinctive sound fields that exist above and below the transition/Schroeder frequency. — Toole, Floyd E, Sound reproduction- the acoustics and…, 592
