So the story goes that I got a great deal on a GB streamliner amp recently and sold off my ampeg 15" combo. Went to audit a GB uber 1288 and 210 at the local dealer and got the 210 after trying for half a day-dealer dosent stock the 115 anymore. The 1288 didnt do it for me....or perhaps I was just blown away by the articulation of the 210s after few years on a 15". Now after a few days on the 210s, I kinda miss the sweet extension of the 15".... I was offered a return to exchange for the 1288 if I wanted to. Here comes the issue, I stay in a apartment and dont play anywhere else without inhouse equipment. How will the 210+115 sound compared to lets say a 1288 or a 2x12. Will a 210+115 produce a significant increase in db or spl? Will a 210+115 retain the articulation of the 210s and the warmth of the 15, or will everything just crap out in a mess? Thanks in advance!
