Thanks for all the input so far! Although I feel I may have asked too general of a question and caused unnecessary arguments lol. I don't want the fridge because of the weight. Never used 12's and am curious if the 15's can fill medium venues with no pA support. I know it's hard to compare this stuff with many different companies putting out cabs with all kinds of capable drivers. There has been some great suggestions so far though! Also there isn't a whole bunch of options at my local store to try. Basically Mesa, GK, and Traynor. (I'm from the great white north, if that matters in any way)
This is one large reason why I chose my Xsonics 215cf. 2 15" speakers, 900 watts, loud - fills venues easily, weighs 48lbs, has tilt-back wheels that don't rattle, nice smooth tweeter, clean articulation, and has excellent tone. You can also get it with an additional 5" speaker (2155cf).
Greenboy knows what he's talking about regarding driver response, and I can tell you that these 15's are NOT slow to respond. (Somehow, I bet all of Greenboy's designs wouldn't include 15's if they were inherently sluggish.

) With my 215cf, the articulation is absolutely on the money, and as I play upright a lot of the time, articulation cannot be muddy or sluggish. The articulation with the 215cf is clean and authentic. I've played 4x10's, 2x12's, 1x15's, and this cab outperforms all of them for what I am trying to achieve.
The great thing about modern bass playing is that there are more high-quality choices out there than ever before. I personally like Xsonics the best, and I encourage you to try one. But other options out there (like fEARful designs) are available. You have to decide exactly what you want, and seek the cab that meets your needs. If you don't want a fridge, don't get one. If weight is not really an issue, so be it, but if weight is a concern/need, don't compromise. Meet your needs as a player. Lots of great suggestions in this thread. Glean out the information that helps you, and choose what fits your needs. Good luck in your search!
You can lead a horse to water but you cant make it drink.
You can hold its head under water until it stops moving though.
But then you have a dead horse. You can beat a dead horse, but it doesn't get you anywhere, and you're right back where you started.
