Not that I'm selling mine, but since you already have a pair of Peavey 12" mains...i've got a couple Peavey 18" Black Widow cabs that go pretty cheap used..I'm pretty sure I saw a pair just like mine for sale recently for like 300 USD (for both). They ain't light though...definitely ain't light
(They have a current model of 18" for just under 300 USD a piece, but I can't vouch for them...mine are like 20 years old)
