I wonder how these sound compared to the Juggernauts.
After hearing the video Josh posted, I'd say that the Juggernauts have a much smoother high end. They 'purr' more. They have a weight in the mids, and particularly in the low mids as opposed to the Impluse set, where the tone seems to be very even from high to low. Far more 'bite' in the highs than the Juggernauts.
