This is my goto sub. i have the xl122r and it is over the top in all areas of spl andsql i am a clarity nut and i like my bass to sound organized! muddy crappy loose sound bass wil not be tolerated. i will by these subs as long as they make them. just look at any other sub of the similar t/s and efficiency at over 92% and it wont be a budget sub! its a massive sub!
