Home Speaker Asylum

General speaker questions for audio and home theater.

RE: The challenge I found

The frequency level pots help.

Sorry, they have no effect whatsoever on the directivity of a driver.

Dispersion collapses when the wavelength being reproduced (3 inches) is shorter than the pistons size. If the tweeter had a similar profile, it would likely not be noticeable. In this case, however, the five inch midrange transitions to a wide dispersion tweeter sitting in the middle of its sweet spot in vivid contrast.

Current versions cross the midrange at 2.2 kHz, not double that.
