Both my brother and I had some Boston Acoustic speakers that we love, but the foam had wasted away, causing the speakers to sound like they had been blown. Took 'em in to Austin Speaker Service, and 8 years after the repair, they still sound brand new. Saved me a ton of money. I don't know how I could give a better review than that. True artisans! Highly recommended! (Not sure about the person who wrote that they were rude, but my experience is that generally, you get back what you project.) They were great with me, explaining what the problem was, how it could be fixed, and how I needed to let the glue dry completely before using. They know their stuff.
