Just to give you an idea, here is an iphone video of the VSI60 driving my new power hungry Studio2's in a HUGE room. This amp is not even half broken in yet and the speakers had only 5 hours on them when this was taken. The amp really only runs out of gas at ear bleeding levels.....or on very bass heavy stuff or orchestral works....
