Guest jlaplante Posted May 23, 2008 Report Share Posted May 23, 2008 I replaced the mids and tweets in my AR-2A speakers with AB-Tech 2AX units years ago, and just now have found this forum only to discover that I may also need to tweak the crossover.Anyone know what crossover changes were made going from the 2A to the 2AX?

Here are some pics of my 2ax crossover:http://www.classicspeakerpages.net/IP.Boar...?showtopic=4466The xo schematic is here:http://www.classicspeakerpages.net/library..._schematic.htmlYou just need 2 pots or L-pads, one 6uF and one 4uF cap and one #7 or #5 inductor coil per speaker. If you use L-pads you may want to add the resistor as shown to the mid.Please be sure to let us know what the xo in the 2a is comprised of.ThanksKent Link to comment Share on other sites More sharing options...
