I have some questions, but first: I am thinking of going from a 4x10 to 2 1x12s. I plan on keeping the same amp (Ampeg PF-500). I have: Ampeg 410HLF Interested in: Hartke HD112 (x2) -If for a reason other than portability, why did you do it? -Were you dissapointed in any way? -Do you have any live experience with the cabs I have listed above and, if so, how did you like them? -How does a pair of 1x12s handle the low B? (Not worried about this for shows with PA support) Why? Half of our gigs, I am in the PA and half I am not. My plan is to use 1 of the 12s when I am, and both when I am not. I understand that the reality is that I will not be sure until I gig with them. They sound fantastic in the store, but we all know that isn't the end all be all.
