Based on what you are looking for (more mid-bass and bass), you'd probably need a bigger woofer. Here are some recommendations for you:
(1) Philharmonic BMR large stand mount speakers can be bought new for $1,950 to $2,100 depending on finish. They have a ceramic 6" woofer, a 2.5" mid, and a RAAL ribbon tweeter. Bass extension to 36hz. Best speaker under $2,000 I've heard, excellent mid bass and bass too
(2) Buchardt Audio S400 MkII (Not the MkI) can be found used for around $1,500. It has a 6" long stroke woofer, and a 5" x 8" passive radiator, with a .75" tweeter in a round waveguide. They claim to go down to 33hz, but I think 38hz is more realistic; still great for a small stand mount speaker......I've owned mine for about 3 years, excellent speakers
(3) Mofi SourcePoint 8s - $2,100 per pair, 8" concentric driver with 1.25" tweeter. Excellent sound, but I've only heard them twice at Axpona shows.....so I'm going off of memory
If you could stretch to $3,000
(1) Fritz Carbon 7 SE MkII - $2,900 per pair, and are brilliant speakers for the money. 7" carbon/paper woofer with 1" dome tweeter, go down to 38hz; very easy to drive as well; incredibly well thought of speakers
(2) Revival Atalante 3 - $3,100 per pair, and again are brilliant speakers....some of the best stand mounts I've heard. 7" woofer with a 1 1/8" tweeter, and claim to go to 44hz.....but they sound like they go deeper
Best of luck
