best speakers on the market in my opinion...for the price.
I have a 2x12 with the vet30 and green beret (GB clone)...sounds wicked. i've also been wondering about that et65 as they claim its the perfect match for a vet30. I think your better off with the vet30 and et65 as it will raise your speaker wattage to 120w (if you running a rm100). my combo is only 90w , however with a rm20 its fine. GB speaker is a little harsh i find, however, i would be interested in how the et65 sounds.
