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,

Bob

A bigger problem in using subs with the Quads (or any other planar) is getting them to sound "one" with the speakers. Dipole users complain that subs produce bass that doesn't integrate with their speakers, sounding detached, tacked on, and of a different character.

Dipole users have tried all kinds of subs with them, the Finnish company Gradient creating a dipole sub for use specifically with the model 63. A dipole sub is a great idea for use with dipole speakers, for the obvious reasons.

There is a VERY unique and excellent dipole sub available, but it requires a little bit of DIY. GR Research's Danny Richie and Rythmik Audio's Brian Ding combined their talents to create the world's only Servo-Feedback Open Baffle/Dipole subwoofer, and it's killer! Voted "Best Bass at The Show" at numerous RMAF's, details on it are viewable on both the company's websites. Highest sound quality subwoofer currently available, at any price, in the opinion of many who have actually heard it.

jzzmusician - In my experience they can be set and forget after the initial (week?) of set up.  I fairly recently got a pair of SVS SB1000.  Not the most expensive subs out there but they have greatly increased my level of musical enjoyment.  They seem to bring something a lot more complex than just "deeper bass".  While their contribution is significant, on another level it is "subtle" (for lack of a better word)....they are sort of figuratively "invisible".  Integration was not the nightmare some have experienced.  I suspect setting them up to round out the bottom end of full range floor standers (my use) would be easier than setting them up to work with limited range monitors.   I do have a complement of GIK room treatments including floor standing corner soffits on the wall behind the speakers/subs.

I set them up mainly by ear but also with some on-line tone samples and a Radio Shack SPL meter.  Maybe not the most sophisticated method but it gave me insights to necessary adjustments.  Gain, cross over and phase all continuously variable.  I don't find myself tweaking them constantly though I sure as heck can hear a lot more of the differences between recordings and even track to track. 

Not trying to contradict any of the good advice Erik is giving you.  Just reporting my experience.

My REL B3 took a week to get set up correctly and I've never touched it since (3 years) with the exception of connecting it to my new Accuphase. You would never know it's there besides the fact that it's big. I have to get on my hands and knees and put my ear next to it to know it's actually working. I couldn't live without it now.

The main problem people have with subs is they turn them up to loud. You should just be able to tell that a sub is in the system. I have set up subs for many friends with all kinds of speakers and have always achieved excellent results. No problems with planars. I do everything by ear.
