small-room bass solution?

Olpot -

The solution to room bass modes might well be a dynamic dipole system, instead of simply avoiding speakers with bass extension into the 45-Hz range.

You see, a dipole's figure-8 radiation pattern will only excite room modes in one dimension, rather than all three. And it is the interaction of room modes that generates large-amplitude peaks and dips. Because dipoles put 5 dB less energy into the room's resonant modes, the bass decays more quickly and naturally, with less overhang and better pitch definition. In addition, a dipole is free from boxy resonances and colorations.

I have a customer who had concluded that he "didn't like bass" because he couldn't stand any unnatural bass muddiness. He now owns a dynamic dipole speaker, and now enjoys bass.

You can read more about the advantages of dipole bass at Siegfried Linkwitz's room acoustics pags, link below. Or you can e-mail me - my familiarity with dynamic dipoles comes from my own experimental systems and from being a dealer for a dynamic dipole system optimized to work well in difficult rooms. Siegfried's commercial designs are manufactured by Audio Artistry, but I sell another brand.
