How to calculate cab size/volume for an 8" speaker ?


Supporting Member
Hello all !
I like small and powerful so my next project is building an extension cab for my Henriksen BUD amp, which has an Eminence 8" speaker built in. The new cab should also have such a speaker . Could I just make a copy of the Bud's cab , regardless of which speaker I put into it or do I have to calculate the exact size for each particular speaker ?
