1987 - 2017: Thirtieth Anniversary!

Replacement/repair part number PRO 002 A
$43.00 each (plus core charge or trade in)
This is an exact replacement tweeter for the following Genesis Physics loudspeakers:
And an improved replacement for the tweeters in these models:
1, 10, 110, 20, 210, 320, 410
11, 22, 33, 44, 66
Some of the later production of these models will use it, too:
The improvement is subtle but noticeable - the aluminum dome I use results in a more extended frequency response, lower distortion, and slightly higher output. It is, however, slightly less forgiving of abuse - the square waves generated by amplifier distortion will sometimes actually buckle the dome, whereas the old phenolic/linen dome would survive until the tweeter's voice coil burnt out completely.
Its internal reference number (on the sticker, if it has one) is STB, STH, STG, or STL.
In sales brochures it is referred to as H50B (or not by name at all).
I will want you to return the old part(s), to recycle the chassis and keep them out of landfills.
This part may be ordered prior to the return of your old part(s), by paying a small deposit, or "core charge," which is refunded upon their return. If you no longer have the old chassis to send back, of course, this means it will cost more.
If you do not have your old parts to rebuild, or if they are in poor condition, I make a new drop-in replacement that does not require a trade-in, the PRO 002 MG.
