If there's one thing any world-class musician will tell you about performing, it's that you need to find the right balance for your stage setup. Not only should your gear be a balance between what you want and what you need; it should also strike the right balance of strengths for your playing style, genre and venue. And that's the great thing about this selection of 2x12 guitar amplifier cabinets: they're a nice midway point between the convenience of a 1x12 cab and the output of a 4x12. They'll give you enough volume and power for almost any venue, and if you want more "oomph", you can combine them with other cabinets in a customized stack - so their flexibility is on-point, too!
When you look through the lineup here, it makes a lot of sense to take your amp head into account. Mostly because you need to make sure the head is a good match for the cabinet, but also because you just might find a cab that's actually designed especially for your amplifier. Take the EVH 5150 212ST 2x12 Guitar Speaker Cabinet for example: it's a natural partner for an EVH 5150 III 50W head. Usually, amplifier makers will also choose speakers that can really take advantage of their own heads, such as the Celestion Vintage 30s loaded into the Friedman 2x12" Ported Closed Back Guitar Cabinet.
Of course, there's no obligation for you to match up your amplifier head and speaker cabinet exactly the way the manufacturers intended. In fact, some of the greatest-sounding setups have been put together by crafty guitarists who know how to mix and match to great effect. So feel free to get creative with your choice of 2x12 guitar amplifier cabinets - as long as it's capable of handling your amp head's output wattage, any one of these cabs could be the best addition to your stage kit.
