Hello everybody
I also have a pair of Batpure tweeters. They are connected to stacked QUAD 57 directly to it’s speaker terminals. The tweeter is mounted between the QUADs with no enclosure (wires and friction between QUADs only support). They sound so good that I just ordered another pair. I intend to use one pair per stacked QUADs. They also seemed to make the QUADs blend in better with my pair of Linn Sizmik 12.45 subwoofers .
