Well, I hold diminutive stripling rock shows in my garage, experience shack and backyard occassionaly, and i provide the mics, mixer, and PA for the band. I use a Tapco Mix 120 http://www.tapcoworld.com/products/mixseries/index.html

and I use a unify of 20 technologist yamaha bag stereo speakers for my pa system, and they are bag stereo speakers, so they cannot handle much, and dont get blasting enough, and so I am looking into buying a unify of radioshack 150 technologist 15” Pa speakers

and whatever of the reviews said you wil need a mixer with 150 theologian :just to get the bass going” and i dont undergo how whatever theologian my mixer has, and im worried it wont work with them, So if anybody knows, that would be awesome. and if it wont work, please tell me what speakers would? keep in nous im on a dripless budget. thanks alot!
Oh and here’s what im using them with, i hit two microphones that i provide for the bands, i hit a rule that I wont mic anything amp over 30 watts, because the pa cant handle it, it can exclusive handle vocals and medium volume guitar amps with mild distortion.
