5 of 5 8 ohn horn purchase January 16, 2020
Reviewer: satisfied customer from Michigan  
The horn diaphragm arrived well packaged and in excellent condition.  It was easy to install (cabinet was already in truck loaded for a gig but I was  able to install it in about 20 minutes R & R).  The horn now works properly.  As to durability, since the horn diaphragm has only been in use for about a week, it is hard to rate as this time.  I gave an excellent rating stictly based on initial operation and quickness of delivery after purchase.  So far so good on both accounts.

4 of 5 So far so good March 12, 2018
Reviewer: Thane Glenn from Bryn Athyn, PA United States  
I was able to replace the blown diaphragm with this one, and it works.  I haven't yet had an opportunity to give the speaker a real work out.

4 of 5 Replacement Foster / Fostex Diaphragm November 8, 2017
Reviewer: Norman Woo from Pickering, ON Canada  
Pleased to find a decent source for these diaphragms. We have gear over 25 years old still out in the field pulling their weight.
Great service - ample stock, reasonable prices, volume discounts, free shipping. What more can you ask for?

Definitely re-ordering.
