.....all that is accomplished by moving the control knob away from 0, is the sub losing authority....comments?.....if anyone says moving the control toward 180 makes their sub smooooooth, I may throw up....what?....too highly opinionated?....KNOW WEIGH!!!....let's hear it......

Craigsub had a great response to this question maybe two weeks ago. I couldn't find it but maybe somebody else can. He roughly said to setup your SPL meter and find the stop that provides the highest volume and leave it there. Mine works best in the 0 position but doesn't make a huge difference either way. I'll be readdressing this question this weekend as I receive my PB12-ISD tomorrow. :D :D :D

Edit: I think this is it:

Even without a SPL meter, if one position clearly produces less bass, then leave it on the one that sounds best, which is probably the other one, "0" as it were.

Hope you will post your reaction after placing the sub and calibrating the system.

Oh I will. Both Buckeyefan1 and MacManNM are visiting the SVS factory today. I'll add my comments to their thread as this is one of the subs they were going to check out. I was going to wait to purchase my sub until after they got back but a black PB12-ISD showed up on the B stock page so I jumped at it. Just in case you haven't read any of my posts before I'm a big fan of B stock items. Buck should have some comments on the SVS B stock page as well.

I'm taking my existing 12 year old Mirage 12-90 along with the SVS to my friends house tomorrow to let him check it out before setting up the SVS in my HT. He has a HK 7200, an Infocus 7200 with a 120" screen, Niles in -wall HD speakers behind the screen, and a cheap sub,and needs more bass to match that big screen. So I may not have mine calibrated until Sunday sometime.
