bass cab blown, Shell worth anything?

I doubt you’d get much for either cabinet.
Replacing the speakers with ones of the same frequency response and resistance is a common practice. If you get neodymium speakers you cut down on the weight a lot.
You can usually find specifications of the original speakers in the owners manual, which is often posted online.

 

Of course, frequency response and "resistance" are not as important as other parameters in determining if a driver will work well in a cabinet.

 

Note that his reply is misleading, you can't just slap a driver into a box and expect decent performance.

 

For selling, you have to compete with this: https://www.guitarcenter.com/Used/Hartke/115XL-200W-8Ohm-1x15-Bass-Cabinet.gc

That's retail, functional, returnable and with a warranty, so cut that price in half if you got it working with a good, used original speaker. IMO you're more likely to loose money or end up keeping it if you put anything that works well into it. If you put anything other than original in it, that should be disclosed when selling. Personally, I would take them to goodwill or set them out for a young aspiring musician to take home and try to fix.You could always try to sell the pair as is for $50. Just put, "All drivers suspected blown" on the ad.

Advice on what might work in these will likely be for speakers that cost more than the cab's are worth, especially modified.

And welcome to TB!

 

You're welcome Raven. It's always best if someone gets them with the intention of doing something with them. If you are a house dweller, you might be able to put a price on them and still set them out. If they get stolen, you still didn't loose money.

I have Monday morning trash pickup. I'll put something out by the trash pickup, often put a note on functionality of not obvious. It's almost always gone by that evening. It helps someone, somehow and beats ending up in the landfill. I almost never sell anything, just too much hassle dealing with other humanoids as soon as there is money involved.
