    Note: If using this diaphragm in a Roland tweeter (KC550, KC500, etc) you will need to cut/notch the horn to install this diaphragm correctly. The original Roland diaphragm had the terminals on opposite sides, and the new diaphragm has the terminals on the same side.

    Reviewer: Shawn Garner
    We ordered these as spares for our rental collection. Perfect match and OCS is very responsive and reliable for having parts we need in stock.

    Reviewer: Dan Quigley
    During the online purchase, I (by my own mistake) had purchased the same item twice on two different orders. I was promptly notified in email and by phone, to ask if this was correct. When I told them it was not, they quickly credited my account and sent the correct item. Wow. You don't see that attention much nowadays! Great service, the part arrived quicker than I expected and I was extremely happy with EVERYTHING! Thanks Orange County Speaker!

    When I changed computers and lost my bookmarks, I nearly panicked. But fortunately, I found this company again and was able to buy parts again. Love this company.

    Reviewer: ken nakamura
    I bought this for my Roland KC500. Delivery was very quick. Now I had taken my amp to a repair shop a couple of years ago for the same problem and they charged me $90. For $20 and a quick and simple repair my amp is as good as new. I would recommend this to anyone. Thanks Orange County Speaker.

    5 out of 55 out of 55 out of 55 out of 55 out of 5 Perfect replacement for the horn in my Roland KC-500 (1.21.2013)
    Reviewer: Anthony Aue
    The highs on my KC-500 all of a sudden sounded incredibly distorted. I pulled out the diaphragm but couldn't see any cracks, but there must have been some really small ones. I ordered this replacement, stuck it in, and now the amp sounds great again. The ~$20.00 I spent on this gamble was certainly better than the $100.00 it would have cost to have a tech do the exact same thing.


    5 out of 55 out of 55 out of 55 out of 55 out of 5 Excellent Replacement for Roland KC 550 (1.13.2013)
    Reviewer: CillySunt
    Received this very soon after my order. I'm impressed. I bought this to fix the tweeter that was not working any more in my KC 550. I never knew that tweeter replacement was really this easy. The video on the website explains everything perfectly. Replacing this was easier than I expected. Because the diaphragm is not laid out the same as the original Roland one for the speaker, the plastic housing on the tweeter needed a little modification to fit the diaphragm. About 10 minutes later, with a pair of snips and a file, I was set to install. I had actually forgotten how good the KC550 was. The tweeter fix reminded me why I bought this amp for my V-drums. One little tip I can give you first timers is to pay attention to which wire goes to positive and which one to negative. Doesn't make much of a difference either way but it is something to look at when you remove and reinstall the tweeter.

    Reviewer: Basil McJagger
    I purchased a similar diaphragm from an online auction-type site. The price was lower but the diaphragm sounded terrible. I ordered this item from Orange County and was much more pleased with the sound. Similar items look identical. I don't know what the difference is exactly, but with Orange County, I know that I'll be getting a quality part that will sound good.

    The best part of all is the shipping. It's fast. Real fast. Usually about 2 business days. I love that.

    Reviewer: Joe Guimond
    Blew out a Foster Tweeter driver at a gig on Friday night. Got online ordered the parts from OCS and had it repaired and fully operational for the next gig. It can't get any better than that.
