$175 · Mach One Speakers (40-4024 Version)

These Mach One 4024's are in very good condition, They wood could use some oil to spruce them up a bit, but they have no damage at all. The 4024 version has the special foam that does not rot and were offered with a lifetime warranty through Radio Shack. They are also the most wanted, and valuable version of the Mach One's. I've included a link to a site that has some mods to improve the sound of the Mach One's if you are so inclined. These sound best when: - raised 10-15 inches off the floor (that's why they are on the milk crates, not included btw..lol..) - as much room between them and me as possible - close to the room's corners, but not right in them - angled ~35 degrees off the back wall towards center - not pointing directly at the listening spot (off-axis perhaps 30 degrees, or the horns "blare" too much) grills off, naturally... Basic Specifications Impedance: 8 ohms Response: 20-25000 Hz Crossovers: 1200, 4500 Hz Speakers: 15″ Woofer, Horn Tweeter, Horn Midrange Sensitivity: 94db 1w/1m Peak: 160W Weight: 65 lbs Dimensions: 28-5/8″ H x 17-3/8″W x 12″ D Original price: $400/pair (1977) From the net: "The speakers sounded best with a high-powered amp running at mid or higher volume. All speakers are balanced to sound best at a given volume (for example, studio monitors vs. concert stacks) and these sound right when turned up. They sound okay at lower volumes, but are really nothing special when heard quietly. Turned up, however, they pour out a wonderful sound." http://www.levlhed.com/docs/tier1.pdf https://sneezl.com/realistic-mach-one-4024-vs-4024a-vs-4029/
