I recently bought a Yamaha YST-SW40 active woofer. I

Can anybody recommend a track I can use to check it; that
has a bass line that uses different notes?

Small subwoofers are pretty much inevitably one-note wonders -
suitable for home cinema, but not music. There is no substitute for
size, I'm afraid.

Your issues are probably equally to do with your room though. Walk
slowly along the room as you listen, and you will probably find that
different bass notes are stressed in different places.
