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?

Thanks everyone.  I don't want to divulge the name of this dealer because I think he has been very helpful in other ways and nobody's perfect, right?  But I will use my subwoofer and I will not worry too much about needing to mess with it from record to record (or streamed album to streamed album in my case), knowing that all of you are enjoying subs every day.  
You don’t want to divulge the name of the dealer? He didn’t do anything wrong -- he has a view about audio and he’s willing to state it. You’re protecting someone who has a greater ability than the average person to defend a view about audio. Why do that? If it's because you suspect they actually can’t defend themself, then you should consider whether they deserve to be a dealer in the first place.
It's called 'Level Matching' (subs to mains).
All you need is a SPL Meter and external 'Test Tones'.
From what I've gathered based on the various subwoofer threads here at a'gon, seems it would be too complicated for the majority of members to invest the time to do it right - oh well...
@hilde45 -- look this was a private conversation with this dealer and I didn't provide him any indication I would be broadcasting any of his personal opinions by name on a public forum so I just feel weird about doing so.  PM me if you want more info privately.
I guess your dealer thinks that you like to play Record Producer instead of listening to an album as intended.
