Stimpy Posted March 17, 2016 Report Share Posted March 17, 2016 As a former Teledyne Avionics employee, one of the (few) perks of the job, was the option to buy products from our sister companies. As such, I quickly exercised that option to buy new, direct from the factory, AR90s. While I've always babied my speakers, and have never over-driven them, other users weren't always that courteous. Specifically, two of my wayward brothers weren't very respectful of my 90s. One brother blew an UMR driver, and another brother, for reasons I can't fathom, decided to polyurethane my speakers. Both cabinets. So now that I have the space and time, I want to get my 90s refurbished, and pristine again. First, the blown UMR was replaced for free by AR, when the original mid was blown. But, unknown to me at the time, AR provided a 200032 mid and not a 200028 mid. Something I just realized, when pulling the drivers. Luckily, I have a spare 200028 UMR, so no issue there. The LMR's and woofers are already refoamed. I did that before the speakers were put into storage, when we were having our current home built. The refoam went fine, though now after reading many of the refoam posts again, I wonder if I used the correct foam for the speakers? From memory, I think I used foam from Simply Speakers and Parts Express. Did the foam have the correct compliance, as I used the generic 10" PE foam? Should I order the JBL 125A foam, for a redo of the woofers? Now, polyurethane? Help! While I'm fine with sanding and touch-ups, what's the best way to remove the polyurethane without damaging the veneer, since I definitely don't want have to re-veneer the speakers? Also, the black paint. Sand and respray? But first, should I remove the acoustic blanket and speaker label? If I do, how hard are they to reapply, and look nice (stock)? Or refinish and just leave 'em Naked-and-Afraid? Finally, capacitors? My last dilemma. I have PE Saved Carts for a NPE recap, a Solen poly recap, a Dayton poly recap, and all of those plus adding cascoded bypass caps to each too. None of the Carts are too expensive. But, every time I 'think' I have my mind made up, I read, "don't use Solen's, they're harsh", or "use Solen's, they're great!" and then another, "don't use Dayton, they're harsh", and then, "NPE's are good enough". Now, to be honest, I personally do think recapping helps a speaker's sound quality. I've recapped brand new speakers, that had perfectly functioning caps, and heard improvements afterwards. Even my wife did as well. So, I guess it's really up to me to decide this one, and make a choice. Thanks for reading, and all opinions are greatly appreciated!
