As an old SVT/8x10 person I was concerned about going to the newer smaller gear. However, after a little trial and error I have settled on a pair of Bergantino 1x12 cabs (HT112ER & EX112ER) and a TC Electronics RH450 head. Combination really does it for me, being more than loud enough and also very flexible and portable. I recently added a classic 450 head which I chain up powering one cab from each head. The reason I got the second head is that I don't like gigging without a spare and as it has the same power amp section it seemed sensible to get one so I can use it. Having both heads in use gives a more solid and focued delivery, with much greater control of the lower frequencies.
