I say, buy them really cheap and post a you tube video of you smashing them up with an axe and setting fire to them.
I often do a hammer test to cabinets that I gutted and found that they couldn't even be repurposed, even as test cabs. I never thought of recording it.
I have taken my short handle 3lb mini sledge to a great number of cabinets out of curiosity and counted the number of swings it takes to level them into 6 pieces of wood. Then I can reuse them to make test cabs but I make sure to start on the correct path right away so I'm not going back to reinforce or stop rattles.
So far the worst was a CERWIN VEGA that was a 12" 3-way in the typical medium stout cab, drivers out, 1 swing with my arm inside the woofer hole aiming at the left side with a right hand swing. It went flat to the driveway and it was like scooping up a deck of cards. Not 1 screw or nail, backing blocks flew off and the 2 that remained popped off by just sliding the boards together.
2 swings for JCP MCS 10" 3-ways, I thought it would have been better?
Various others from Radio Shack and white van stuff held up pretty good other than my hammer going straight through the wood since they were chipboard and only ⅜" to ⅝" thick.
Panasonic floors dual 8" 3-ways proved to be indestructible and no sides could be loosened even a tiny bit. They would have been saw dust with all corners and seams still forming a frame. Of course I stopped trying after 3 big swings. They became a set of testers that I'm still using right now while I contemplate exactly how I want to design final cabs.
Some speaker makers start off on the right path but seem to think that a great cabinet (sturdy and quiet, built to be tank service ramps in a pinch) will make their drivers they sourced from some Chinese or in their case Malaysian no name company will magically sound great even though they lack any type of planning or testing prior to starting production. Using 2 different 8" drivers that run in series, somehow doesn't really need cabinets with 2" tops and bottoms and 1½" motorboards with drivers that resonate at 80Hz! Then they rate them at 200W-400W and the tweeters burn out in 30 seconds, funny how a single tiny cap lacks filter properties to protect a 30W rated driver from burning the voice coil lead wires like a fuse on a firecracker even at 100W.
Sorry for going off track as usual, l came to find out if these were real speakers since I like the size of the cabinets, I was considering using them for a project. Sellers asking $40 and I can't even get a sheet of wood that's big enough to make a cabinet this size let alone make it look like something without spending another $100 on glue, screws, paint and sandpaper + 3 weeks time to plan, fab and finish!
That's based on the sheet being Medite ((now priced at $55 a sheet, preBiden price was $35/sanded oak veneer 10 ply ¾" sheets went from $55 to $99 (Birch is even more) 4'x8' sheets)) chipboard is still $20 or so a sheet. Unless someone can confirm they are not chipboard then I'd be ready to go pick up. I think a gal is selling them so asking her to identify the wood type is probably not going to happen.
Double parentheses!
I'll look for more Panasonic towers.
