I don't have this combo loaded in any of my speaker cabs, but sold a pair of Heritage H55s to my buddy to pair with his V30 in a Savage 4X12 and they sound killer. I tried it with my old Engl Save 120 that he has now and brought my Gowner/Fortin KK++ over and all I can saw is wow!!! It is like like the best of both worlds with tons of low end of the H55s paired with the gritty mids of the V30s. I have a pair of the Heritage H55s left that I thinking of pairing with the V30s in my Splawn, but I am kind of lazy.

Currently have the G12H30 70th Annys in there and they sound great paired with the V30s!!
Another great combo that I have in my Marshall BHW cab is the Heritage H55s on the bottom and the Heritage H75s on the top!!
