mfaz28 Posted March 13, 2017 Report Share Posted March 13, 2017 I'm sure I accidentally fried my midranges after a complete overhaul. What is the current best recommendation for replacements, including an upgrade to AR5 status? Thanks.... Link to comment Share on other sites More sharing options...
genek Posted March 13, 2017 Report Share Posted March 13, 2017 The 2ax and 5 have very different crossovers. It's probably not impossible, but it's a much bigger job than just swapping out the drivers. Original cone drivers show up on ebay all the time, cheap.

Aadams Posted March 13, 2017 Report Share Posted March 13, 2017 Upgrade to AR 5 would require difficult and practically irreversible cabinet mods as well as completely different crossover. Also, AR 5 midranges are not as numerous as 2ax midranges. Link to comment Share on other sites More sharing options...

From one newbie to another, doing my first overhaul, what did you do to fry them, so I'll know not to do that? Rob Link to comment Share on other sites More sharing options...

Rob good question! as others have said, 2ax mids are fairly plentiful and I see no less than a half dozen on the bay for sale right now. get guidance before just buying some but generally $30-$50 per driver. try to get a set that comes from a set as opposed to singles of different life journeys. posting a wanted to buy in this forum is an option as well. good luck and don't be afraid to ask questions, this is a very helpful, like minded bunch! welcome Link to comment Share on other sites More sharing options...
mfaz28 Posted March 13, 2017 Author Report Share Posted March 13, 2017 Thanks for the info. Fried via volume knob exuberance. Just bought an original pair from E@ay. Still would like to increase durability of the midrange with potential new replacements, as in the future the supply is inevitably going to dwindle. I've been very pleased with the new tweeter recommendation per the expertise developed here. Link to comment Share on other sites More sharing options...
genek Posted March 13, 2017 Report Share Posted March 13, 2017 Surprising that you fried the mids but the tweeters are still working. Link to comment Share on other sites More sharing options...

My experience with a number of these drivers has shown DC resistance to fall between 6.3 and 7.2 ohms, but that is just a working guideline to check your "new" pair.

lARrybody Posted March 14, 2017 Report Share Posted March 14, 2017 Ar2ax's were produced and sold in large quantities. Like the Pioneer SX-780. Lots of stuff out there. The tweeters are the delicate driver in this model, thus the higher prices for them. Mid ranges not so much. Link to comment Share on other sites More sharing options...
mfaz28 Posted March 14, 2017 Author Report Share Posted March 14, 2017 I will apply all advice offered ASAP. Including meter check on the incoming pair. Just surprised that an appropriate replacement hasn't been explored. Tweeters were already replaced, hence the next vulnerable component was the mid's? ........Thanks.

mfaz28 Posted March 14, 2017 Author Report Share Posted March 14, 2017 Ahhhhh....The old "25 ohm resistor" trick.......That I just read...Looks like I missed that one! Always enjoy getting smarter....Thats why I married a teacher...!! If this keeps up I'll need a HD pillow..... Link to comment Share on other sites More sharing options...
genek Posted March 14, 2017 Report Share Posted March 14, 2017 There's never been a pressing need to explore 2ax midrange replacements, because there's a never ending supply of them on eBay. Link to comment Share on other sites More sharing options...
mfaz28 Posted March 14, 2017 Author Report Share Posted March 14, 2017 Thanks...Think'n I missed the resistor mod to the L-Pads and thats what surrendered. I'll know in the nest couple of days. After the snow stops in western NY, and I can park the snow blower. At least I'll have a spare set of mid's.....Stay tuned...Different bat time......Same bat channel.....

mfaz28 Posted March 17, 2017 Author Report Share Posted March 17, 2017 While I've been waiting for my stock replacements to arrive. Ive been pondering my possible mistakes. The only difference (so far) that I can come up with. Is the re-routing of the wiring from direct, to through my sub via the high output connects. Possibly increasing my amps output so that the mid's and tweeters are seeing much higher output? I say this because I never exceeded the previous highest volume level used.

mfaz28 Posted March 23, 2017 Author Report Share Posted March 23, 2017 Installed the replacements. performance is better than the originals. Now I'm thinking they were half cooked when I got them 6 months ago. Thanks to all for guidance. On to the next project....... Link to comment Share on other sites More sharing options...
mfaz28 Posted March 24, 2017 Author Report Share Posted March 24, 2017 Is there a recommended place (or places) to have the originals restored? Link to comment Share on other sites More sharing options...
mfaz28 Posted April 2, 2017 Author Report Share Posted April 2, 2017 Now that I have my original replacements. the polarization comes into question. Yellow dot opposite the yellow wire ?? no way to battery test cone movement. How to polarize ?? Thanks... Link to comment Share on other sites More sharing options...
