Different subwoofer settings for different albums?


So a dealer I know told me that he doesn’t use subwoofers and doesn’t know anyone who does (!) because he finds that every record has different levels of bass and would require a new subwoofer crossover point to properly blend with the main speakers.  Anyone else have this experience?

Not my experience.  If a Clapton album was mixed so that the bass and drums are down in the mix a little and the focus is on the guitar, that's what you're "supposed" to hear and a sub(s) won't accentuate that if you have your levels set correctly.  If Deamau5 wants to make your liver quiver with the bass, then your subs should do that at the same settings.
Oh man.  Oh man oh man.

Subwoofers integrated correctly are glorious. 

If you find yourself raiding their gain, you probably didn't set them up correctly, and should consider actual tone controls.
Set your sub or subs properly (not by ear in my book) and forget. The sound recorded is what I'll listen to, and with three subs down to 25Hz I'll only hear what is on the program, nothing more or less. Having that clean tight ultra-low last octave adds a lot, but only when it should. Mine are 100% sonically invisible.

If I have a recording that is just too lean, or being played too low in volume, I can use a 'loudness' type button to help add a subtle bit of low end curve. I use it for low volume listening mostly. I never touch the subs once dialed in.


In days past we didn't have subwoofer control. Your system just played the bass notes as they were produced on the album. Some albums had little bass and some had room shaking bass. Your job was to get your system to sound right and correct playing unamplified music to get the bass balance right. Once set, that was it, and you just played your albums as they were. 
Today, I find myself adjusting the bass all the time but mostly because of the Fletcher Munson Curve and the loudness level I am using at the moment. As I play louder, the bass gets turned down and gets more natural.
