I purchased a cheap peavey 1516 cab with a distorted sounding 15 and i am looking to replace it. Peavey calls out a 1502 4 BW replacement. After researching the topic I have seen several people wanting to upgrade these cabs but I haven't seen any of the results after upgrading. So I am curious as to what was or is the best replacement driver. Should i Go with the peavey replacement or go with something different?
