I know this topic has been covered in regards to the Goliath JR (2x10) but I am looking for info about the 4x10. Here is what I would like to know: A - I have the 8ohm version of the cab. What is the individual speaker impedance for this cab? B - Based on A, what drop in replacements should I be looking for? These PAS speakers seem to be hard to find and I need a functioning cab for shows whilst I get my bad speaker re-coned (at some point). Basically I'm looking for a well available speaker that is drop in compatible. Thanks!
