Question for sub woofer users


I'm kicking around getting a sub for my Quad 2805 speakers.  Here's the question;

Are subs "set and forget," or do you have to constantly fiddle with output volume and crossover point with different recordings?

Thanks in advance,

One thing no one seems to mention but that I think is very important  is phasing the sub properly. Soundoctor.com has plenty of info on sub setup.
He is the tech support guy at JL Audio. They know a thing or two about subs.

Great site!  Thanks!
Technically they are supposed to be set and forget. But I find they need tweaking depending on the program material. Nothing to do with the other equipment, just variables in the recordings.
