[dassy]

Hi,
Im gonna be investing in a MESA BOOGIE RECTIFIER HEAD,

also im gonna be investing in some cabinets/sepakers for it of course, (2 speaker cabinet)

but i want CELESTION speakers, are these pretty much the best speakers for mesa heads and what kind of CELESTIONS are the best,also can i buy CELESTION already in a cab so i dont have to buy other speakers im just gonna take out to replace,

what do you suggest?
