We have 6 of these subs in the team now ( a live band ). They cover 90% of shows, either with 1 or 2 subs. The power to weight ratio is fantastic - which is what you get when you spend a bit more on a sub, as well as a great sound, thus saving your back! For smaller shows we use 1x sub and 2x 10" tops. For the larger shows, 200 guests plus/ larger rooms/ marquees, which account for 10% of shows we use FBT 15" subs or 4x of these fabulous 12" subs. They are really a no brainer.
