    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?

    First off, your two assumptions are incorrect. Bigger box doesn't necessarily mean deeper bass. Also, bigger speaker doesn't necessarily mean deeper bass or louder volume.

    Both the Aggie and the Bag End will give you loud, deep bass, but the amp you're using also has an effect on the quality of that tone.

    Acme uses 10's in small boxes and put out some of the cleanest, loudest bass out there...but Bag End's tend to have 15's as their ideal driver. It seems that the 12's in the Aggies are what most people have. It's all about the drivers used, the ideal geometries of the cabinet for a particular driver, and the quality of the amplifier.

    You're correct. The technical term for what you're trying to describe is Hoffman's Iron Law. If you want to go lower your options are either to use a larger box or more power, or both. The problem where we're concerned is that there are finite limits to how much power a driver can handle before it runs out of excursion, at which point the only way to go lower or louder is to go larger as well.
    As far as comparing any two cabs is concerned that can be done by either trying them side by side or by comparing their complete specifications, including the all important displacement limited output versus frequency chart. But since no manufacturer makes that information available it's a option that's not available.

    What amp are you using? What size venues will you be playing? FOH support? Loud band? Loud drummer?

    Since the manufacturer's specs are built for sales brochures, you really need to hear a cab with your amp before buying it to really find out what it's all about. It may sound different with a different amp so what you're hearing from other TB members may not always apply to your situation.

    That being said, here's a few links that may enlighten you:
