Welcome to AK. It would be nice to see your wall unit. Glad to hear you're happy with the Mach for so long. I too have the 4024.I still have my original Realistic Mach 1's (4024 bought in 1977) in mint condition. Never replaced anything and they still "ROCK". Plenty of BASS! I use them for Music and Watching Movies and NASCAR. They still pound the house when I want them to. In my opinion, they are the best speakers made for home, even though they were made from Radio Shack. I have them placed on their side above my Wall unit I made back in 1980. No sign of wear on the Walnut case.
