I recently purchased 4 Technical Pro Speakers and an amp, this is my first setup, and i must say i am very disappointed. I realize now technical pro makes low end speakers. I just saw them everywhere i went to buy speakers so i assumed they were alright. There are 2 VRTX 15's, 2 VRTX 12's and a TPro TA-4000. I hooked everything up and realized after removing a woofer there is a sound in what i believe is the voice coil and it sounds like a BB from a pellet gun is rolling arround. What could this be? How Could I Fix It?


Thanks, Matt
