Anyone have any experience with these 410 cabs ? They are heavy, but apparently sound great. Very little info out there on them. I have a line on one cheap Its one of these: View attachment 2965164
I played with a pair of MBC 410's. Loved them, but, as you said, very heavy - 91 lbs each. Finally got rid of them to avoid back problems.
I had this cab coupled with a 1-15 box, same series. I learned that 4 10s wasn't my thing and sold it. Got the 2 10 version instead. The weight was a killer.
