No drivers and the main amplifier is not communicating with the slave speaker (to be clear, one amplifier works)

Beyond my skill set but have had a look to see if it’s anything obvious, no loose connections or bulging capacitors.

The input 3.5 jack is temperamental and loose but the USB input seems to work fine.

This listing is for the cabinets only with the issues described and no drivers.

The cabinets are very well built and in overall good condition, could be useful for a pair with damaged cabinets etc.

Q150 LS50 R100 drivers will also fit 5.25 inches.
