teknofossil Posted December 7, 2019 Report Share Posted December 7, 2019 Hello. Does anyone possibly have a schematic for this module that AR sold intended to upgrade the performance of the AR1 and 1w to a AR3 levell? I'm sure my responses will say it is the same as the AR3. Does the module duplicate the whole crossover or just the the high pass filter to the midrange driver? Thank you! Tom Quote Link to comment Share on other sites More sharing options...
genek Posted December 7, 2019 Report Share Posted December 7, 2019 There were two add-on modules. The AR-3st contained the dome tweeter only and the AR-3t added both the mid and tweeter. Don't have schematics, but here's what they looked like with their backs open. Quote Link to comment Share on other sites More sharing options...

Tom Hi Teknofossil, DonT long ago published on my request the AR3-st scheme, under the photos You find the thread by typing: original AR paperwork I have! I also used AR-1MS to make a medium / high section only to the AR2 woofer (I still have to attenuate the small AR-1MS with appropriate resistances!), Find the thread in the Mods section (moved there by moderator Genek!) Under the title: AR-2t I hope I've been helpful Giorgio Quote Link to comment Share on other sites More sharing options...
