Hi all, I've always had a head and separate cab setup so haven't run into this before, but I have an Ashdown ABM 300w combo with built in 15" speaker and wondered if I added an extension cab at a later date are there any hard fast rules?
I understand that a speaker's size doesn't necessarily dictate how much bass/air it moves, but could I add something like a 2x10, a 1x12, 2x12 or 1x15 etc without any worries such as comb filtering as there's no horn/tweeter on the combo.
Also, the combo has a slit port across the whole width along the bottom, I presume it would still work as intended if the combo was sat on top of an extension speaker, or would I need to put the extension on top of the combo?
Cheers
