A DIY episode. I made this as I replaced the foam surrounds that where rotten on my Realistic Mach Two Speakers from the mid 1980s.
They are 8 ohm, 160 Watt, speaker cabinets with a dual radial superhorn tweeter, a 5 inch midrange woofer and a 15" ferro fluid cooled subwoofer.
They where made by Tandy, and sold at Radio Shacks.
