Interesting. You could make a stand that spans the width of the lower cabinet and support the top cabinet from the floor. This would completely isolate the two. It would only take a few minutes with 2x4s to “prototype”. If it works make something nice out of hard wood. gershman acoustics does something like that with their black swan speaker. The top part spans the woofer cabinet and looks like one speaker.
Klipsch Lascala II bin separation
A unique feature of the newer Klipsch Lascala II and AL5 is there are two bins, top and bottom (or HF and LF bins). Recently I put a cut up Purple seat cushion between the two sections and the clarity jumped significantly. Everything is better, very much better. Has anyone ever tried to seriously isolate the two bins? Is this a thing I just never heard of or is this a commonly known deal? The improvement is so huge I thought someone out there would have sounded the trumpet long before now. Sorry if I'm late to the party.....
