I'm speaking here from an imprecise understanding, (FWIW), but my
sense of 'bass slam' is as dependent on the harmonics as on the
fundamental -- they both have to be present, appropriate in amplitude,
and undistorted. You may have issues with the harmonics which could be
high enough in frequency to be muddled by first reflections. Have you
tried putting centering your speakers on the long wall well away from
the end walls. Your room is big enough to not feel cramped with this
arrangement.

By the way, many moons ago you recommended Obligato caps, and led me
to try them in the parafeed positon in my S.E.X. Amp. I like the
result very much. I meant to mention this to you in Dallas, but
the opportunity didn't arise. Thanks,
