If 80's and 60's are supposed to be identical excpet for how much louder the 80's will go and the 80's being a little deeper you could go 80, 60, 80...no?

My first upgrade was the VP150 which I had for a year before buying my 60's and QS8's. I am happy with the VP150 but like everyone else I think the other speakers are just that much better...
A big consideration has to be placement though as well. I did notice a slight improvement once I wall mounted my VP150 and aimed it to my position.
