I use 3/4" melamine backed hdf cause I get it for free.
That's what dude uses for anything lighter weight or prefab, Idc either way.... I brace accordingly. Hdf can d the job if FACTORED in, II still swear by Russian Birch... .6875" thickness and all... anyways....
Amazing how sum 6.5" slam. Prefabs... Sure Wilbur
HDF boxes btw...
I'm NOT a small sub guy but will admit they can do the job. He did a dual Xfl-12 box that pushed 150db with that Hdf so it's solid, but materials always factor in the design.... Ima geek like that... sorry. Rise and all.... lol, We use 6" lag bolts /w/ resin and PL down here in Az to hold OUR boxes down (less rise).
100% #Facts... we got a bridge for sale on the border too.
Given larger more capable subs for instance I insisted on a 2 ply triple baffled design for a single Zv5-15... on 5K... Sanded pine...
Or nailing it with a 2py , triple baffled Russian birch design... this thing was crazy I was told.
Materials go out the window once you go 4-15's wired down on 16v.. I heard this one did 156+ out the gate on 4K clamped or so
... but these guys are THOSE guys... crazy what testing can do isn't it?... I heard it was 158+ on 4K last report clamping the same... tuned 28hz this thing is peaking low... Hi voltage-low wired-dead cabin (or setup)... a pair of budget amps shouldn't put out THIS well.
Man... I do kinda miss the shows (and the people) until I remember driving 100-300mi to sit in 100+ degree heat, watch god knows who cut in line and if I won I'd walk away with a license plate for a trophy and be on "the list"... lol.
Az list?.. i think I made the Usaci 3K stock list somewhere along the way as well. Certified Spl ... fuk all these crazy numbers coming outta smaller shows, a regional or final where its not a collection of buddies metering you. Gee... I wonder why I just stopped competing?
I saw some shady stuff... but I digress.
I like that Hdf
