If you want a bookshelf speaker with bass, listen to the Generation 4 by Watkins Stereo.

If you like the Atalante 3s but want deeper bass, larger soundstage, better imaging etc you can add a pair of subwoofers to your setup and that should do the trick.  You could spend half of what some of the recommendations cost and get excellent subs that would likely give you what you want.  I added a pair of subs to my system and it did all the things I mentioned above. If you don’t want to entertain the idea of subs then forget I mentioned them 😀

My sound signature is warm with great bass, not to bright or harsh. I listen to all genres of music.

I realize driver size does not make a speaker. I was also intrigues with the Trenner & Friedl ART speakers.

When I say high end, I mean quality parts handcrafted type of speaker. Not a mass produced Chinese manufactured speaker.

Gershman Studio xDB have an 8" woofer, but are relatively compact stand mounts speakers that will go down to 23 Hz.  They convey a lot of detail, have great imaging, project a huge soundstage, and manage to be a bit on the warm side and very easy to listen to.  Made in Canada by a smallish boutique company.
