Sorry to repost this question again but I would like to hear from the owners of these cabs and get thier opinions on which one has the better bass response. I know the UL 410 is a bigger cab and bigger cabs tend to have more bass response. And I have tried a UL 410 and liked it. But I have yet to try an AE410. My situation is that I play in a real loud rock cover band. And I need to push low end because sometimes we use our own P.A. system at gigs and I do not go through it. So its up to my amp to move the air. I am using a Mark Bass Little Mark II right now going through an Ampeg SVT 410 HLF. Which weighs about 110 pounds. And it is brutal on my back. So I need to get a light weight cab that is 4 ohms. Any help would be really appreciated. Thanks.
