ok so i have decided to leavee the 12 inch world and upgrade to a single 15 for next years comps. the only thing is i cant decide which one would do better for a comp and also do good as a daily driver. My choices so far are a nightshade Hdc315 or the new alpha. the amplifiers being used would be 2 1500 sundown amps strapped for comps and a single 1500 for daily outa of the three which would be better
