Howdy all, It's time for me to upgrade to a full stack. i love my avatar 2X10 as it has great mids and highs, but it lacks some bottom end, so i'm considering either the 1X15 or 2X12. i'm a college student so price matters. that being said the 1X15 seems like a better option, but here are my questions: What are the ups and downs of each? Would the 1X15 give me substantially for bottom end than the 2X12? I'm going to be primarily using these as a stack, so i'm thinking if i got the 1X15 i wouldnt need to get it with another tweeter horn...is this a good idea? or does the 2nd tweeter make a difference? any thoughts and expertise on this matter is greatly appreciated. thanks all.
