What would be the advantages and disadvantages of each? I like the idea of having two separate cabs so that I wouldn't always need to lug a single huge cabinet around every time I want to play somewhere. The GS212s together would be more efficient than the 412 too, correct? However, the 2 212's would be more expensive than the 412, so I'm not sure which to go with. Is there anything significant I'm not taking into account here? What would you do? Also, I have one other question about Aguilar's cabinet specs. The GS212 specs say "Frequency Response: 41Hz to 16kHz" ...is this flat, -3db, or what?
