@jw944ts You have a very good setup. Ravel go down to 23 Hz at 3db. So you should get good low frequency response. First you need to measure frequency response of your system from the listening position using Stereophile Test CD or similar with test tones. You can use radio Shack meter to measure frequency response. This should give a very good idea whether you are getting a good bass response or not. Room modes play a significant role in the low frequency reproduction.
Also identify some source material that contains low frequency information. For example, I use Wishing Well track on One Night in Vienna by Peter Scott and Richard Schönher that has a drum in the middle of the sound stage that goes from start to finish. Another one is Wrecking Ball by Emmylou Harris. If your room is not shaking, then you have a low bass problem and may have to consider room treatment.
