I'll start by saying that I know nothing about amps apart from guitar goes in one end and noise comes out the other. Saying this I have found these Harley Benton cabinets on Thomann which have 2 x 12" Celestion Vintage 30 speakers (verified by Phil McKnight of the Know Your Gear You Tube Channel). Now these cabinets are selling for $227 and it seems to have some people frothing at the mouth. So I guess my question (finally) is, what makes these speakers so special? Why are these cabs such a good deal?
