Great parts
I bought two of these to repair my SWR Silverrado Special cabs. I had blown both high drivers playing some music through them for practice one night. I pulled the horns and replaced the drivers with these which are a perfect fit and I have back my total sound from my cabs.

Foster & Fostex Speaker Diaphragm Part # D-420
I bought one of these a few years back from a different website to fix the horn on my Bassman 200 (took the darn thing to a football field and cranked it back in my teens and blew it out, then again at a gig a few years later) and it works great. Hopefully I'll be mindful of the horn and attenuate it next time I blast it on full.

Was looking for a diaphragm for a 2 Soundtech horn drivers. Didn't know if these would fit. Got them in the mail. (Delivery was excellent.)And they fit like a glove and work well also. Actually had looked everywhere else on the internet a had trouble finding a diaphragm that fit. My horn drivers are vintage. The cabinets they go in a made of wood not the new plastic. Price was cheap enough too. .

Professional bass player.
I needed to replace Diaphragm in my SWR Goliath 4-10 cab. After seeing very helpful video on how to do this, I ordered this unit. Received it in a very timely manner, replaced it, and I'm back in business working my show. Than you Simply Speakers.Well done.
