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.

The right tap is the one you like best. The impedance curve of the Sopra is pretty wild (but most modern speakers are) so no tap is 100% the best.  
You can gleam some insight into the Sopra 2 by looking at the impedance curve vs frequency (link blow)
Each lower tap is a different contact point in the auto transformer output and as you go lower you cut voltage and bring up the current. It is best to match the load but when the load swings like crazy it can’t really be matched. 

the short version is if you run the 2 ohm tap you get more power where the impedance is low but less power where it is high. With the Sopra being all over the place I am not sure it matters what you choose. 
But really don’t over think it. If it sounded more open on the 8 ohm tap just use it. The Mac has enough power to plow through it anyway. 
On a side note I think crazy impedance curves are why large powerful amplifiers sound better. Not because you need the power (again only using 4-5 watts) but the big amps just freight train right through these impedance curves. Where lower powered amps can really get tripped up over them and get hot and compress.

Where did you get the Kimber? Are they biwire ? Put some photos of those connectors ( amp and speaker and especially bi-wire ) in your virtual system page.

life is a freaking tone control, smoke Em if ya got em  until sorted out…,
Holy cow!  Proper phase connections.  Nobody (including myself) ever mentioned that...until now.  The very first potential problem to look for when there is an absence of bass is proper polarity, or, phase connectivity.  And it took this long.  @tomic601  good for you to advise on this to the OP.

As Homer Simpson would say... Doh!
I've had the kanta for awhile now and findings are such;
Utilized the sumiko speaker setup to get bass dialed in, once done, the extension is marvelous.
Utilized the 4ohm taps on amp.  I remember someone telling me that focal was disingenuous with it's 8ohm rating.
