I received a referral from a local electronics store for Audio 3000. My 8” powered sub-woofer had stopped working and the original home theater installer was not responding. Upon contacting the original manufacturer I learned the subwoofer was out of production and a replacement would be over $800.00. I brought the unit to Dennis Sardilli and he replied back with the bad news that the power amp was fried, probably due to lightning. I asked if there was anything that we could do to salvage the speaker and housing, as they were in perfect condition. Dennis searched the internet and found some parts to re-build the unit and the result was just fantastic. For $300 bucks I have a brand new sub-woofer with a larger capacity amplifier and the sound is just awesome. Thanks Dennis!!!
