I’ve never found a speaker I really like in an X pattern with V30’s. But in a horizontal 2x12 and top/bottom 4x12, I’ve had some good mixes. I’m a speaker whore and currently have 43 raw frame speakers piled up in my garage……..Celestion, Eminence, Scumback, WGS, Jensen, and Weber. And those are just the ones I can’t sell.
In a 2x12, my favorites were pairing it with a Lynchback or Creamback 65.
Probably going to get a lot of WTF’s here…..but In a top/bottom4x12, I love the Neo Creamback top with Mesa V30 bottom. I have 2 cabs with that. One 1960a and a 1960b. Check out Zilla cabs mixing those on YouTube.
If I had to go X pattern, then it would be the Jensen Nighthawk/V30. They are identical in dB and fill out each others shortcomings perfectly when far out in front. But I just don’t like the variation when standing on one side of cab in close proximity.
Lots of in between, but what sounded like shit to me were Redbacks (hate that speaker) and G12-65’s (both vintage and modern Heritage).
