Alright.. After becoming a bit frustrated over searching countless threads from here and other websites, I STILL Cannot find the Information I'm looking for. So, if you all could kindly please post Any and All information you have about the different versions of Realistic Mach One Speakers including the Original 4024, 4024A, and later 4029 Category Numbers, that would be fantastic (Pictures even better!). This will help me out a lot and also I'm sure many others out there, too, trying to figure out if their speakers are the better ones. Ok, here it goes. Number One, The Surrounds. I've read from plenty of places that people say the 4024 versions had Rubber surrounds, others say they have the hard foam-like/styrofoam-like surrounds as the 4024A's have (that do not rot as easily). If there is Truly a difference with the surrounds of the 4024 and 4024A's, someone please confirm it here. Next, The Drivers... I already know the 4029 models have the 6ohm woofers, but do the original 4024 and the 4024A's use the exact same 8ohm woofer? I have the 4024A version and they have the 8ohm woofer, along with an 8ohm SH-2 Tweeter and 8ohm SH-1 Mid Range (all Japanese made). I've looked around on the internet and noticed there are 7ohm Tweeters, too.. Were these used in the 4029 versions? Now, the Crossovers. I guess this is really where having the most precise information is key.... Probably the biggest question I have out of this entire post is, are the crossovers for the original 4024 and 4024A versions the same? I have found no pictures or information anywhere of the original 4024 versions, But I will be so kind as to post pictures of two different 4024A Crossovers I have. The first notable difference is the layout. Now, both of these are 4024A versions, but one has a slightly larger plate. I looked them over very carefully and found no differences with values or numbers whatsoever. I will go ahead and post a picture showing what a 4029 Crossover looks like, but It's not mine and I do not own it. Picture only being used for referencing. Above: 4024A Crossover Above: 4024A Crossover with larger plate, and slightly different layout Above: 4029 Crossover Please! If anyone has a picture of the original 4024 (no A) Crossover, can you post it? Thanks a bunch! Now I suppose we can move on to the visuals... Yea, they all look the same.. Except for, of course, the woofer surround material (compared to the 4029), the L-Pads, and the printed information on the crossover plate. ALSO... I've read and noticed that somewhere along the lines in production, the 4024A versions had the bottom of the cabinets switched from being all veneer to being plainly Painted. The internet (after much digging through countless forums of different sites) has told me that this may be caused by cheaper costs of production. If this is true, then wouldn't there also be a difference and shift within the quality of the 4024A models during the time they were being manufactured? I suppose this would explain why the two 4024A crossovers I have look different. With all of that said, this raises more questions... Would this mean that these "cheaper and maybe more inferior" later-produced 4024A versions may Not be of the same quality of the earlier produced 4024A versions with the full veneer cabinets, and even more so Not be the same quality of the original 4024's? Would this cheaper line of 4024A's being produced, would that put them in the same category as the inferior 4029's? ... So, with this being known, does that mean there are actually 4 different versions of the Mach One Speakers ?!?!?!?! Has anyone ever thought of this? Maybe the 4024A's are not at all like the 4024's? Maybe I'll win the lottery tomorrow? Yes, I know there are many, many different threads out there about these speakers, but I'm still so full of questions and finally broke down to post a thread about it to hear about the specifics. Hopefully everyone with Realistic Mach One experience can post the true facts about these speakers to finally, once and for all, put the question of 'quality issues' to rest. I'd ever so greatly like to hear any replies to the information I have posted, or any New information that could help! Again, if anyone has more photos of specific differences, please post them, Especially a picture of the original 4024 crossover. Thanks a million!
