    Higher impedience will also have a higher BL. The BL is a measure of the "control" of the woofer movement with higher being tighter.

    Visibly, there is a difference in the thickness between a D130 and a 130A so they do not use the same cones, even as replacements. (There are also internal differences such as wire material.)

    I've also found that "flat" may not be the most musical nor the most intelligible. While the overall curve should decline slightly, I like a bit of "brightness" in the 1-4 kHz area and it only...

    I would suggest that you be very careful handling the "horseshoe" clips. While they are silver grey in color, they are ferrous and will be drawn toward the magnet, right though the diaphragm, and...

    Current State of the Mermans

    This is the current crossover configuration. Unconventional, but it seems to work well.

    Like I said, Wurlitzer uses reeds and Rhodes uses wands/tines to produce the sound and I think that the reeds have more harmonics. Both have a sustain pedal.

    I also did more work on the Memans and decided that with 4mH/30 mfd on the 2241, I could get a better better blend between the 2241 and 2251 at the higher end of the range (~900 Hz),...
