Cheap fix for blown tweeter horn
I bought a used KC550 last week and thought it sounded great. Got it home and found a funny sound when I used it with a Hammond XK3 and digital piano. Pulled the horn and sure enough, though it was producing sound, it was not as clear as I knew it should be. I got online and found Simply Speakers was selling the diaphragm for $16.95 and decided to give it a try. The unit arrived this week and I went to install it in the horn. Unfortunately is is not a simple installation. I have a shop and tools but had to create a wider opening in the plastic horn base to accommodate the two connections. Roland had each connection, positive and common on opposite sides of the plastic horn. Once I created the opening in the horn, I only had to make a jumper for the common connection from the amplifier. I tested it and it works great! Just a warning though, that this is not a simple fix for non tech types. Response from Simply Speakers: You have the newer version with the terminals 180 degrees apart. Normally we replace the entire driver for these, but very glad to hear you were able make the new part work.

Mr
This Voice Coil worked perfectly to repair my KC550 tweeter. Watched a you tube video on how to replace a voice coil and had it repaired in no time.

Review tweeter voice coil.
Item works perfectly. Had to file one tab to fit the push connector but not a problem. Thanks.

Roland: KC-500, KC500, KC 500, KC-550, KC550, KC 550, and many more!
For Roland KC550 confirm terminals are side by side and not 180 degrees apart before ordering. Will not fit Roland SPK-KC550 models made in China with terminals on opposite sides.
