so my friend/bass player is possibly going to buy a 70's V4 cabinet to use with my sunn concert lead (or possibly my beta bass once it's fixed) for bass.

is this advisable?

i've used my v2 cab with the same head for bass with no issues (it has the original CTS/utah square magnet speakers.)

a very good tech told me that the speakers would handle bass fine, but i've seen threads about people switching the speakers for bass use.

so what's the word?
