Hello fellow bassist, In my quest of a stand alone cab ,i have read many post here on TB , The more I read the more confussed I get, so let me ask a few questions, Frist I'am not an Engineer of Acoustics, but from what I'am gathering is your going to have to give up something in every case. If you go compact your going to give up cab volume. And if you go to a bigger cab your going to gain low end. I was looking at a bag end sd15 cab ,The cab is no bigger than the speaker,really compact, but am i going to loose low end. Another cab i was looking at is an Aguilar Gs112 nt ,it's a 12" speaker but it's in a bigger box that's going to give me more low end. So is more cubic inch or foot in a cab is going to increase the low end or is there other things involed in the tuning of a cab. I 'am used to useing 15s but it is looking like I may try the 12 what do you guys think am I going to get better low end response fron the Aguilar 12 than the Bag end 15?
