I have a close backed speaker cab i have used in my rehearsal space for 3 years. The speakers are jaguars and i believe them to be in pretty good shape. I will let you test and see on my guitar and amp. I can also send a video demonstrating 2 different heads.
It looks rough (not sure why the previous owner removed the protective front netting/cover, but this hasn't been moved much outsideof my rehearsal space.
The 2 speakers are each 8 ohms and routed parallel. So they sum to 4 ohms. Even though i used these for guitar, You could run a 100-120 watt bass amp without blowing them.
$50 obo, i can deliver for $20 within reasonable distance.
