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?

I don't have a problem with applying EQ. 

Using the subwoofer's level adjustment or anything else though.... Ugh.
@mijostyn - for now, not doing the DIY thing, but I am curious… maybe someday

@m-db - what is this software you describe?
I have had excellent results with setting up my new pair of REL carbon subs using Anthem STR integrated with ARC room correction. I tried the High level connection but I am much more please using the bass management in my integrated amp. It is not only about the crossover of the subs but also how it aligns with the roll off of your main speakers. My Focal Sopra 3s go down to 30Hz which is also where the subs start to fade but the bass is much better overall by setting my speakers to crossover to the subs below 75hz. I believe a Bass Management/DSP system is very helpful in getting the sub integration right.
