Agreed... "My perception of sound" and all that it encompasses to attain it... at that point, if you like what you hear, thats all that matters.

The 1” foam I’m using is from Parts Express. Sonic Barrier 1” Acoustic Foam. It has an adhesive backing but it didn’t stick very well so I used a few 1/4” staples (the original foam was stapled as well) to secure it. I may leave it as I now have it because it’s much better than what was originally inside. Easier to add more if needed. Thanks everyone for your thoughts and suggestions.

I’ve decided to update my Chorus II's - Crites Crossovers & tweeters already done, I’ve made new component gaskets , sealed all inside joints and updated the damping with 1" acoustic foam on the sides and tops of the cabinets - (I bought them with pink fiberglass insulation already in the cabinets and will be removing it). Instead, I was thinking of adding denim insulation above the woofer to fill the top area. Is that too much? Can you over do it with sound damping and significantly affect the sound in a bad way? Thanks!

Thanks for all the information everyone. Since I had previously updated the crossovers & tweeters and now have the Passives out (and like many others now spending more time at home) I’ve decided to complete the updates on these speakers. I’ve taken all the components out and made new gaskets, sealed all the inside joints. The cabinets are in excellent condition and are seemingly very solid (no bracing needed at this time). BUT - the previous owner added pink insulation in the top of the cabinets which I can appreciate sound wise. However, I’m not a fan of the fiberglass fibers laying around inside so I’m looking for other options (foam?) to possibly replace the insulation with. The original grey foam (one wall covered and a partial wall and the top covered) is still intact. I was looking at melamine foam but it’s very expensive especially for the amount I would need. Any less expensive suggestions would be appreciated. Thanks again!

Thanks for the info. Hmm hadn’t thought about dynamat to the horns. I have sealed and braced the cabinets to my stacked NLAs and it made a huge improvement. I’ll have to look for pics of bracing on the CH2. Thanks again!

Im working on updates to my CHORUS II's. I have added Crites crossovers and titanium tweeters, fiberglass insulation in the top of the cabinets and dynamat on the woofer baskets. Would I gain any benefit from putting Dynamat on the basket of my Passives? Thanks!
