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.....

Success! The Iso-puck 76's work much better than those crazy 'purple' cushion things I made. Radical enhancement of clarity in the entire frequency range. I wish another Lascala owner would try this so I can see if this really helps other as much as it improved my speakers. This may have been the Achilles heal in the Lascala all along. The rubber feet between the upper and lower Lascala bins were heading in the right direction! 

I've ordered 6 Iso-pucks 76's to place between sections to see if this helps even more. As soon as I install and listen I'll report back since I know there are many Lascala owners in the family here. Crazy how much clearer these babies have become with this little tweak! Makes me wonder about all the speakers that are sticking all the speakers into one box. Could the bass reverb be disturbing the mids and tweeters? Surely. But if they're all locked into one box then there's no way to unlock them from each other. The bass seems it would be the main "disturber of the peace". This would make separate sub out very helpful. This gets that energy out of the main speaker body hence improved clarity throughout. But thats just me thinking out loud. 

"I might have to try something similar to what you’ve done with the LS." ozzy62 Please post here as to what you discover by isolating the HF from LF bins. I used the purple seat cushion on a whim since cross disturbance from vibration is what manufacturers attempt to minimize by adding deadening material within speakers. (And other tricks) Even Klipsch doesn't just plop the HF bin upon the LF bin but provide 4 rubber feet. Admittedly, they are more stable than the 6 IsoAcoutics Iso-puck 76's I've got on the way. (3 per speaker)  So Klipsch wouldn't want to be liable for breakable and unstable pucks. The top section weighs 72 lbs. (Klipsch Forum) I had all but decided to sell the Lascalas to ascend to greater audiophile heights but this tweak has so clarified the overall presentation I'm sufficiently blown away to sit happy until my OCD finds fault once again. Terrible affliction (OCD Audiophile) 

The Iso-pucks lift the top high enough so the rubber feet aren't touching at all. I've built gloss black rods to fill in the gaps where the two pieces look sweet together while these black square rods (aprox 1" X 1" X 24") do not touch top but fill in gap for cosmetic effect. Big clarity enhancement. To James633...I've thought about the total suspension of HF bin by exterior support system but haven't thought of way to do so in an artistic/non-intrusive presentation yet. I'm very curious how much improvement would come from  total true isolation. Honestly (as I mentioned) I really didn't think the Iso-pucks would make much difference. Boy, was I wrong.
