EPI 500
My EPI-500's had been sitting in storage for the last 20 years due to deteriorated foam surrounds. I ran across your website and ordered the kit. It was fairly simple and easy. Took me a total of 1.5 hours. Time and money WELL spent! I had forgotten just how awesome these speakers sounded. My 16 year old son was very impressed that speakers older than him sounded so good.

EPI Time/Energy 360 EPI 4" Foam Speaker Repair Kit FSK-4
Original owner of a nice pair of EPI Time/Energy 360's that are great sounding speakers but the original Base and Mid Range foam had dried and needed replacing. So I bought the EPI 4" Foam Speaker Repair Kit FSK-4. Kit came with everything needed and repair was very easy. Speakers sound like new now and am very happy with both service, shipping and Foam Speaker Repair Kit. Thanks to Simply Speakers I'm enjoying my speakers once again!
