wow, I don't even know how to respond to this post. For a start he has only one sub and you would have him spend a couple of hundred on a minidsp for 2 aligning two or more subs. Second, he knows exactly where the null is. Third, less EQ is always better than more EQ.
Placing the Subwoofer in the seating position isn't outdated at all. It's still one of the best ways to position your Sub correctly.
Not at all.
You can get a dramatically better, smoother response with one sub using a miniDP2x4HD.
In subwoofer world, in no way is less EQ better than more EQ. A subwoofer, unless in a perfect room in a perfect room, with perfect placement, will have peaks and nulls. The peaks can be just as detrimental to the sound of a subwoofer as the nulls; because the peaks will drown our the accuracy and lower bass frequedncies which don't generate the same ammount of SPL.
I've had DRAMATIC increases in sub performance, accuracy and sound with a minidsp2x4HD even when running one subwoofer.
Doing a subcrawl only shows you the position your subwoofer generates the most perceivable SPL. Its essentially a guessing game for performance. You won't know how your sub performs at 20, 40, 60hz.. and your sub might even be encountering multiple nulls and just having a bloated big boom from a few frequencies instead which is perceived via the sub crawl as 'good bass'.. its not!
You're not going to get the tightest, best sound following a cheap subcrawl.
MiniDSP2x4HD is a buy once, cry once addition to any decent setup which wants a good level or LFE.
Likewise it also opens up the usage for BassEQ and custom filters for films and videogames.
Its not one of the best ways. Its a crap, cheap way. Measurements and seeing the response curve are far far far far more advantageous than moving the subwoofer around a room. A sub crawl is a very cheap method for finding the part of the room where your sub generates the most SPL and thats all. Its not going to provide you with a smooth response curve, its not going to allow you to pinpoint which frequencies are there for peaks and nulls, its not going to educate you on if and how a second subwoofer will perform in the same space etc.
What is your expeirence in subwoofer calibration and optimisation in a home theatre context to allow you make such bold claims that a subcrawl is one of the best ways to position a sub? Its a cheap method but its far frar far far inferior to any method which allows measurements of the response curve. What setup do you have? What subs have you owned? Which rooms have you had them in? What measurements and use cases do you have to prove your subcrawl is performing at all a smooth response for sub performance?
How do you using a sub crawl ensure your subwoofer is putputting the smoothest bass response across MULTIPLe seats and listening positions?
whether its worth the investment for a PB1000 is probably a different argument and comes down to your own cost analysis. in my experience, its dramatically improved even cheap subs like BK ones so I'm sure it'd work some magic on a PB1000.
