Martin Posted September 16, 2018 Report Share Posted September 16, 2018 This is what an A40XL crossover looks like. I've owned these for 40 years & have never opened them up. Figured somebody, somewhere may be curious, although these are rarely seen. Sounds like an A25 with extended high end and with greater efficiency & power handling capacity. Just replaced the cap & like what I hear very much. Quote Link to comment Share on other sites More sharing options...
Dogsled2 Posted January 28, 2019 Report Share Posted January 28, 2019 Apparently one can see a coil in series to the woofer in the A40xl. Interesting...The A50's also had a coil (6dB high pass) to the woofer. Quote Link to comment Share on other sites More sharing options...
Pete B Posted February 10, 2019 Report Share Posted February 10, 2019 That inductor is across the tweeter, follow the yellow wires to black (ground) and white tweeter wire on the selector switch. Quote Link to comment Share on other sites More sharing options...
