i want to get a celestion V30 for my peavey valveking, but i read somewhere in a review that it will not fit because the coil is too big and like hits the tubes? does anyone know about this or how i can get around it? thanks.

Measure
Easy.

Find the measurements and see if it will fit.

And BTW, Eminences are IMO much better speakers for the price. They're better quality, and cheaper. (Made in US, 7 year warranty, Celestions are Chinese.)
