[QUOTE="mat3833, post: 8831000, member: 587645"] LOL, meme lumber. While I definitely appreciate that comment for what it is, this is not meme lumber in the slightest. One of the builders i work with at the granite shop just switched to it this year for certain cabinets. It's expensive, but it's zero void, 19-22 layer, full birch plys. I was going to double baffle 4 of the panels to 1.5" with the cheap 7 ply 3/4" and make the top 2.25", but Dan showed me a sample piece of the 1" vs the 3/4" 15 layer they use. At 24" the 1" was deflecting 1/8th with 500 pounds in the center. The 3/4 started making cracking noises at 400lb after deflecting about 3/8ths. This stuff is freaking strong, and the plys are 45 degree layout, not 90 so you get alot more uniform strength. I don't know all the math and whatnot and I don't know wood that well. But if the main custom cabinet guy switched to it over 1.5" glued panels(cheaper for him) for outdoor kitchens with granite countertops, I'm inclined to listen when he suggests it. I think I'm going a full 2" thick on the top panel. The front/sides will still just be 1". I don't see myself running anywhere near full output on these for very long, and I won't be getting more power either. So 5k on a 14 cubic foot net sealed enclosure for 2 18's. Matt [/QUOTE]
