What Our Clients Hear Now
Finding Tim was a lifesaver. I spent a month’s salary on some amazing speakers in the 1970s. After decades of wear, they sounded muddy, but Tim expertly salvaged the original drivers and precision-upgraded the crossovers. Now they deliver incredible imaging and punchy bass. For honest, transformative audio work, Tim is truly the best.
Bill F. – St. Louis
“My B&W Matrix 800s were missing their tweeters and crossovers. I found Tim, and he matched a great set of Morel tweeters and replicated the original crossovers with improvements for the tweeter and phasing. I couldn’t be happier.”
Mike M. – Las Vegas, NV
“I brought Tim my 55-year-old Pioneer CS-63DX speakers. He replaced all the capacitors with modern, long-lasting ones. I was surprised how affordable it was, and they definitely sound better than ever!”
Dave H. – St. Peters, MO
“Tim built me a custom audiophile speaker with high-sensitivity pro parts in 1986, and I loved them for years. When my 500-watt amplifier failed, it took the speakers with it. I brought Tim my cabinets back and he built another custom 15-inch, 3-way pure audiophile speaker. I can’t believe I own speakers of this quality.”
Tony B. – St. Louis
“My parents have a beautiful pair of JBL L100T speakers and I wanted them upgraded. Tim replaced the foam and did some updates—WOW, these things sound great!”
