What's a good box product for reducing box volume?

Craft foam blocks? I've used books and sandbags in the past but they aren't great for permanent use-age. I want something that can be attached and left in place.

Wood?

Just install a wood panel to make a separate enclosed space. Use the secret compartment for a crossover or your weed or whatever. Good place to hide that extra pair of tweeters you didn't tell the wife you bought...

Great Stuff foam might work. May want to let it cure for a few days, not sure. Never tried.

Ceramic tiles glued to the sides adds mass and rigidity.

I glued old pieces of travertine tile to the inside of my Udique XL box. I was surprised that it made a noticeable difference. Loved the weight and heft of the speaker.

I have access to 2" blue styroam insulation sheets. Should work?

It's not the tweeters I have trouble hiding, it's all those Rival woofers that Gowa keeps selling me. My wife calls him an enabler.

I have used 4x4 cedar before since it doesn't add much weight.
