Thumbs up What to do with a large broken JVC Loudspeaker cabinet?

Found this large JVC loudspeaker cabinet outside and wondering what to do with it.

You can see all the drivers have been mutilated and there's only their driver frames left:

The back MDF panel has a large hole in it:

I am wondering whether I can re-build a single cabinet from it and put my Logitech subwoofer driver in it instead of its current enclosure. Also wondering whether there's a good way to repair that MDF hole or if it's preferable to just make a new MDF panel to go with it.

Suggestions are most welcome.

You should have left it "outside" where it belongs.

The question is what can I build with it now that I have it, at least as a partial MDF enclosure.

Strip the drivers and parts and chuck tha box away IMO
The driver frames make good places to hang invoices and bills from using a second magnet in reverse{ tweeters}

You're lucky you didn't pay for it. This way you don't have to pay a lawyer to get your money back.

Measure the Logitech's TS parameters and then simulate so you know
if it would be worth repairing.

Making a new panel would seem to me too much of a trouble. Take a piece
of panel larger than the hole, set it over the hole and make a marking so you
know where your router should go. Make a rebate for flush mounting a new
panel. Your new piece would have to be less thick than original depending
on routing depth.

I don't know if that makes any sense to you.

Well, the boxes are salvageable inasmuch as you could patch them up. But if you're planning on dropping your Logitech sub in them, a number of points come up:

-You'll need to ascertain if the Vb of the patched up enclosure is appropriate for said sub, and adjust the tuning appropriately.

-You'll need to fabricate new front & rear baffles assuming you want a vaguely attractive finish.

-Again, assuming a vaguely attractive finish, you'll probably spend more time & effort patching up the clapped-out JBL boxes than you would building a new cabinet. Especially since (if you have any specs. for your Logitech unit) you will have more flexibility to adjust volume & tuning, and can probably build a better / stronger / stiffer cabinet.

-With the above in mind, frankly, I'd break them up, unless you just want to have a bit of fun experimenting with the Logitech in a different volume. The balance sheet comes down in that direction. You might be able to salvage some of the material so it's not wasted.
