RobHolt Posted January 4, 2015 Report Share Posted January 4, 2015 Something I'm considering as an experiment, here's why:Over the years it becomes apparent that the classic 2 way paper driver ARs adopted an ultra-simple crossover with just a single tweeter capacitor of around 6uf.One has to ask why, and I can come up with a couple of reasons but primarily I keep returning to questions of cost and simplicity, particularly in the lower priced smaller models.But there is a price to pay IME, since all of the capacitor only 8" bass driver models suffer some upper mid energy excess and cupped-hands colouration on vocals. This is the inevitable result of running the bass unit high, and a less than optimal power response from this relatively large driver operating into the upper mids, then crossing to the much smaller tweeter cone.So I'm wondering if the older designs which rolled down the woofer earlier and crossed the tweeter a little lower were in fact superior from a pure performance POV, though obviously more costly to produce.Therefore, given the AR6 and AR7 in their later mid 70s incarnation used the same drivers, I'm going to experiment with the AR6 type B crossover on the AR7.Anyone else tried this, or interested in the project which I'll happily document with measurements?Rob Quote Link to comment Share on other sites More sharing options...
