Subwoofer for classical music listener

Just be happy you can hear the overtones of say, a Bach fugue , all you need to glory in the music .

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

Gallo TR3 is 799$ new, used ones don’t show up on here(a good thing). One sub is all that’s needed to play the odd organ piece and relieve mains from
burdens below say 80Hz which brings more clarity which is always needed .
I’ve heard Vandy subs but IMO Gallo beats them.
If your Oppo is less than a 105 a Cambridge CXC transport(449$) might do more for system than sub .
Might do more if it is a 105 .

Some say two subs evens out bass in room. I've found one is enough IF you get the placement right .

The Gallo TR1 or TR3 is perfect for Classical , fast, clean and very good tone .
Works in any room and any system . And they are cylinders which look nicer than a box .
Don’t believe the old BS you can put them just anywhere.
They work best dead center between speakers with front of cylinder 1/8 "
in front of face of main speakers .
Rest, do what teo says . In my room crossing over at 80Hz is best for my
Totems, Rega’s Omega’s, Gallo’s and Meadowlarks .
 My listening is 70% classical, 20% jazz and 10% Celtic and other folk
music .
