Bass traps’ inadequacy pushed Toole toward multi-subwoofer mode control.

Evidence

It is likely that this experience encouraged me, years later, when I had a bass resonance problem in my home listening room, to seek other solutions. This led to my first visually unobtrusive multiple-subwoofer manipulation of room modes, and Todd Welti’s subsequent work to be described in Chapter 14. — Toole, Floyd E, Sound reproduction- the acoustics and…, 1383
