No... I got the 600 through the outlet and buying the 800 would mean no 10% discount and thus an extra $900. Since this is my first nice sub I'm not sure the gains in going deeper and louder will be noticeable to me. So many people seem very content with their 500's and 600's that I figured I'd just give this a go first. I'd be interested in others opinions.. is the difference between the 600 and 800 worth another $900?
