Report Ricci's Skram Subwoofer & Files in Bass Projects Posted July 30, 2019 4 hours ago, Timon said: Hey guys, my friends and I are totally fascinated of the Skram and for now we want to build two of them. At first we'll build it with the suggestion of 18mm birch ply and after we want to do some changes for the second pair. We want to make it out of 15mm (birch ply and in the core of it one layer of poplar to make it lighter) in addition we would like to add some braces out of carbon and epoxy resin. It should be as stiff as 18mm birch ply. Do you have any concerns with this plan so far? We are not sure which kickbass we want to use. Maybe some of you have another recommendation? We are planing to build one Cubo Kick 12 per Skram with the 18sound 12ND830 and a little bigger cabinet, so it gets down to about 90hz and up to 200hz. The other consideration is to build some sealed boxes as kicks but I worry if this will be very harmonic with the Skram. But it should be the purest and punshiest kick, isn't it? There would be I guess 2 drivers per Skram (depends on the driver). What do you think? What would you do? As Mid Tops (from 200hz with a bit different AMT) there will be one Mundorf AMT (with a horn in front of it and an active cooling system) and two Wavecore WF259PA01 per side.. Mostly we are playing Techno, etc. but the system should be able to let you enjoy all kinds of music... It would be great if you guys could help us with your knowledge! Thanks a lot, Timon I would advise against the combination of hardwood and plywood, as both have a different CLTE. If you're really limited on weight, you may try to use Banova Ply. You could do the outside panels with regular BB ply and use the Banova for all inside panels (and be my guinea pig at the same time 😉) Other than that, I'd personally prefer to keep the speaker count at 2 (i.e. one or multiples of the same sub playing from 20/30Hz to 60/100Hz depending on taste and a (line) array of the same capable tops). I had a quick look at the tops you're using and I don't see the need for a kick bin here. The dual 10" tops should capable enought to cross them over between 80 and 100Hz, and the Skrams are capable enough to be used in that configuration as well.
