bfastr Posted May 2, 2018 Report Share Posted May 2, 2018 I finished the restoration of my old AR4x speakers today. This was previously mentioned in the topic of My Misery. a basic re-cap is these were my Dad's speakers. in the early 70's he bought four AR4x speakers for a multi room setup. somewhere in the late 80's he moved on to Advents and I snagged a pair of the AR4x speakers. Way back when I did the unthinkable and gutted the speakers and put in some Scanspeak woofers and tweeters. I knew better than AR right? The modified speakers served me well as extra units that I didnt pay much attention to. At one time I augmented them with a giant 15" subwoofer that would shake my house. the wife hated that. crank it up!! well time passes and I started to get interested vintage speakers. So I happen across a pair of AR2-ax speakers in really fantastic shape locally on craigslist. So after doing a little work on those ( also outlined on here) I started to think it would be cool to turn back the clock on my non original, but in very nice condition AR4x's. So, after sourcing drivers and tweeters off ebay I decided to restore these to original. Well, I did one at a time and after replacing the whole crossover board in the back ( I had gutted that too..) I cleaned up the mounting flanges and epoxied the holes I had drilled for the other speakers and refitted the original drivers. The original 20uf caps both measured around 21uf, but I decided to use new caps anyway. I also bought a pair of the phenolic ring tweeters, even installed one when I messed with the first speaker, I ended up settling on that tweeter and went back to the Scanspeak woofer. and there they sat for a month, one still as I had "improved" it back in the 80's and the other with an original crossover but still non AR speakers. I tried the old AR tweeter, but it just sounded weak, so I used the PR tweeter. for a month. that brings us to today. I decided the heck with it, I am going ALL AR4x on them. So the only thing new is the Solen 20uf cap, but both speakers are back to original AR speakers. The sound.. VERY Pleased! the woofers seem to have a lower bottom end than the Scanspeaks did, at moderate volumes they sound fuller, The original tweeters sound balanced and much like the AR2-ax speakers I have, with both speakers properly configured and playing I find the overall balance perfect. Playing alongside the AR2-ax speakers they are fantastic. I also noticed the AR tweeter sounds brighter with the new caps versus when I tried using the original wax cap. But the balance once built as designed is very pleasant. I am really glad to now have two variations of AR speakers as designed. Its amazing how good the old AR4x speaker really was, I can see why they were so popular. It would have been cheaper to buy another set of all original AR4x speakers off ebay than what I probably spent on speakers, caps, wire and all the other stuff I bought and didnt use. But thats the fun of doing this sort of thing, plus these cabinets were my dads.. worth more than the sum of the parts to me. Bob F Link to comment Share on other sites More sharing options...
