Different subwoofer settings for different albums?

redwoodaudio, Now you are on to something! You can get that kick ass bass at home. You are missing it for two reasons. Speakers are specified in an anechoic chamber at 1 meter, not in a room a 3 meters. Most speakers start losing it at 80 Hz or higher!  And, of course they do not go low enough so you are missing all the low frequency transient information you get at a live performance. I have seen Dave Holland 3-4 times at our local jazz club. His Quartet records like Not For Nothing and Prime Directive are recorded with his exact stage set up. His bass is beautifully detailed so, I frequently use these discs to evaluate bass.
To get the best result with less farting around you need at least two subs, 12" or larger, up against a wall or better yet in corners, digital bass management like with the MiniDSP unit, amplifiers greater than 1000 watts into 2 ohms with a damping factor higher than 500 (I use QSC commercial units) and passive subs. Passive subs are very inexpensive if you can build your own. Parts Express (Dayton) has some excellent kits and their sub drivers are some of the best. They make drivers for a lot of other brands. Dayton's own drivers are such a good value because they are not marked up two or three times. Check this out https://www.parts-express.com/Dayton-Audio-15-Ultimax-Subwoofer-and-Cabinet-Package-300-7097  These are a breeze to build. If you decide to go this route message me and I'll be happy to help you get the best results. The only tricky part is putting a finish on them. This can be done professionally if you are queasy about it. If you prep the cabinet correctly it is not that expensive and you can have a piano finish put on them which looks killer. 

You can inform your dealer in 2003 a Digital Drive servo subwoofer was introduced which allowed detailed automatic and manual frequency interaction with a main speaker system. The accompanying six customizable frequency presets may have satisfied his concerns.
By 2011 the software was expanded to a Plus version.

The main speakers are responsible for analog playback to the point where their design begins its low frequency roll off.
At the beginning of the speakers roll off the digital software used by these subwoofers allows the user to begin designing an optimized crossover region using a Frequency Response and Parameters tool that makes multiple adjustments of Individual Parametric Filter EQ, Parametric Filter Frequency and level, Q (Bandwidth) Parametric filter, and gain all by using a simple visual drag and drop while listening. 
The result is, for the most part, an unnoticeable crossover and a sub frequency presentation that more closely matches the main speakers low frequency presentation. 

Since these initial equalization settings are subtly blending with the main speakers its suggested they be used on all six presets down to the frequency the user would like to increase, flatten, or decrease bass gain to accommodate the rooms demands and/or the music to the users personal taste.  

These software adjustments allow a blending in of multiple crossover parameters rather than a typical subwoofers hard crossover setting at which point the basic sub simply turns on at its full predetermined gain which may or may not match the media being played. Possibly leading your dealers complaint regarding subwoofers.

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.
