...vs Pyramid? I think Boss is better than Pyle and Pyle is better than Pyramid. I heard Pyle, Pyramid, Lanzar and Legacy are all made by the same company. Also include other brands as Sony, Audiobahn, Dual, any other low-end brand in the compairson. I have a Boss amp and 15's that I think are okay; I want 18's though and Pyramid and Pyle only have them. I'm looking mostly at the Pyle PL1890BL 18 inch subwoofer.
