i finaly ordered my sytem, got all audiopipe! went with the new audiopipe tsvr 15's with an audio pipe ap15001! ordered through vminovations! the subs are not beasty but they are efficiant, and tons of cone space with the new updated cones and surrounds! i think ill be happy with them as this will be my daily set up! after talking to audiopipe these driver's are suppose to be great for low end extension!
