You don't lack bass, you have too much treble

@curiousjim Perhaps you just don’t like those instruments which produce sound at those frequencies. It’s not your system. I don’t like trumpets live or recorded and if I built a system to make the trumpet tolerable to me, it would be a misrepresentation of what a trumpet sounds like, along with every other instrument or vocal. For some reason, there are frequencies that don’t appeal to me (live or recorded) and I don’t like song that include those frequencies or have alot of energy at those frequencies. Do you enjoy those instruments/vocal live?  Does the trumpet bother you if it is at 75 db?  

Beyond that I would look at different speakers or dampening in front of the tweeter.

@curiousjim Well those are the non-speaker reasons for what you are hearing.  The other possible reasons are amplifier distortion or the speaker is compressing. That is, for whatever reason you are reaching the limit of the driver motion, and that seems odd at such low volumes.

I don’t know how to answer your question.  It’s not just a trumpet. It’s anything from a Saxophone to Joni Mitchell’s voice to an electric guitar.

I've had minor success, but one has to pick very carefully.... ;)

Lord knows I’ve tried,  but when she came home after spending a couple of weeks with her sister and found some Maggie 3.7i’s in the family room, it was all over for me!
