Motorola powerline tweeter drivers#

The pair of boxes in the making are low-cost ones for the neighbor's ambience music outside on the deck/near the pool. JBL Selenium Brazil did make lower cost 'copies' of the latter, such as ST200, ST-304, ST-400, and ST-350 (50°X50°), as well as Sammi (China?) HF 200A, and of 2405 as HF 250. Motorola's most famous being the KSN 1005A 3 1/2' Super horn tweeter, which I'm tempted to call somewhat of a 'poor man's version' (not a copy) of a 2402 for example. My understanding is they are deemed to be the high-end of piezos. Motorola Engineers published in the JAES about their invention or discovery in 1975 if I recall correctly, and their specific design is patented. They can't be all stupid in my view, though admittedly not high-end drivers, but can still do the job adequately. Motorola did sell tons of these not only for individuals, but also to some known speaker manufacturers, as well as less known ones, and still counting under other names (back on this later).Īmong known manufacturers who used these: Community, Peavey, Fender, Sun (piezo source). Though Piezos are not 'noble' and snobbed by some, they're still known drivers, of low-cost that can produce acceptable sound if they are properly accompagnied by a simple crossover network.

This simple project is a way for me of letting go some older drivers in good shape as replacements arrive. I have different types of drivers from various manufacturers since I like to try a number of things.
