Subwoofer for classical music listener

"So-called" classical music is not an elitist term.  Admittedly it is a vague genre. But it usually, but not always, indicates acoustic music. There is electronic (synthesizer) classical music and jazz-oriented classical music using electrified instruments.  The term is just descriptive to differentiate it from other forms (folk, ethnic, jazz, etc.).
As you say, it generally relies on natural acoustic instruments, but in a specific space (concert hall, auditorium, club, studio, etc). It is this variable of space that, I believe, makes it more difficult to reproduce on playback.  Spatial elements are more critical in acoustic music and therefore harder to reproduce.

" You , knowledge, wisdom, reason, manners and logic are mortal enemies "

You are obviously confused to believe that things like knowledge and wisdom are mortal enemies indeed a sound argument can be made that the absolute opposite in the case. However you obviously have some deep inner need to attack my commentary on this esteemed board and should you feel that my contributions here are not worthy of sharing space with someone as knowledgeable as you because they detract from your ability to share your wisdom I invite you to alert the moderators and seek to have me dismissed from this board. In the absence of action from them I will continue to speak the truth here especially when you assert such absurd notions such as your defense of so-called classical music as presenting some deep exceptional unusual challenge to your Music Reproduction System that is not the equal of any other kind of music which you apparently hold in some deep-seated hatred so that you can cultivate, display and promote your so-called superiority over others who you regard as ignorant. Have a nice day.

I don't think others are ignorant . I know you are .

So, rvpiano, are you going to get some Vandy 2wq's?

Yes!
Thanks to your recommendation and one other that was glowing, and a price I couldn't refuse, I bought a used one on Audiogon.
The only problem now is to find a crossover that matches the impedance of my amplifier.  I suppose I can use the sub just the way it is now without any damage.
I wrote to Vandersteen about obtaining one.
