I need some advice on which cab would be the best for my situation. I play in a pretty loud rock cover band. And I have been using an Ampeg 410hlf for a couple of years now. But because of a recent lower back problem I have to find something lighter. I own a Mark Bass Little Mark II. And I have tried the Mark Bass cabs but don't like them. Plus they are 8 ohms and I need a 4 ohm cab. So I have narrowed it down to 2 cabs. Either the Epifani UL 410 or the Bergantino AE410. Which cab do you think would handle high volumes, produce lots of low end, handle low frequencies well(we do a lot of songs in drop D and C and I also play a 35" five sting) and last but not least not break my back. Thanks in advance for your opinions.
