I'll be getting a BBE BMax and PLX power amp soon and will be looking into replacing my SVT410HE. it just doesn't have the bottom end or volume I'm looking for. The mesa cabs seem to have a much smoother sound to them. I am looking for a lot of punch too. Just found out my manager has two roadready R5410(1x15 + 4x10) in her garage. they belong to the bassist of one of her old bands and she is going to ask him about selling one of them. What can I expect in diference of sound, tone, volume between the mesa and the SVT. basically what is everyone opinion of this cab. thanks.
