Sopra 2 Bass

New member, first post, and newbie in terms of diving into the world of nice things. This world is insane! I've already been spiraling for a few months researching what to buy, AB'ing countless speakers and amps. I now own a McIntosh MA9000 that's driving my new Focal Sopra N2s via Kimber 12VS. My "dilemma" is with the lack of BASS. I demoed the N2s, so I know it's possible, but absent in my home. I have to use the tone controls (this is where you tear me apart) to bump the low end. I do not know if it's my room, lack of bass traps, or equipment, but I'm failing to get down a little lower without tone adjustments. I stream Tidal Masters to my wired Bluesound NODE 2i (optical to the MA9000 dac). My room is 11'x20.5' with a low, 7.5' ceiling. I have tried as many speaker positions as possible with little change. I already know I need to eliminate room echo in the center of the room and have been researching various acoustic treatments. I feel like I'm off to a good start, but now stuck, not totally satisfied. Yes, it's the best I've ever owned and mind-blowing amazing, emotional, etc, but just short of perfect for me. In tracks where I expect a punch, I get an unmoving transition... Can I get "there" with different wire? Should I consider a sub? Why do folks on this site use two subs? Do I need to hire someone to properly sound-treat the room? Is my room a lost cause for what I own? Reaching out because I'm stuck, afraid to waste money chasing dead ends. My budget is thin after the McIntosh and Focals. Any help would be so appreciated! I hope to learn, grow and pay it forward some day. Thank you.
