What's the weakest link in my stereo set up? I live in a townhome, so limited on space.

While figuring out a new furniture setup to get larger speakers in your space, start auditioning some interesting finds, not to buy but to refine your preferences, listening to your Focals all the time.

Facebook Marketplace, this is speakers for sale, 100 mile radius of Baltimore, $200 to $2,100.

Don’t mistake loud volume with full range when you see large drivers.

Perhaps below are too big, but for example: I am a big fan of level controls to adjust tweeters and midrange driver levels relative to their forward firing woofer, in your space, to your and your wife’s ears, with a SPL Meter and Test Tones (no ports or like these front ports only), on stands that are slanted and toe-in away from side walls.

btw, after you finish chasing very low bass, especially in a space like yours, you realize it can be fun mud, I have my rear ports plugged in my current space, there was no wall behind them in prior space.

I live in an apartment and a REL Tzero is perfect for me.

You can adjust the volume if needed.

I would then get a MC cart.

Given the situation, I'd treat the room 1st.  Instead of one sub, 2 smaller self-powered ones.  Then swap carts if a new stylus doesn't curl your toes.

New speakers in that room shape calls for serious shopping and considerations/trade-offs and hopefully chances for home auditions...

At  least you're in a metro area that potentially has B&M shops....
Closest thing to a 'club' here is this:

Listening area is 'bout 12' w x 16'+ long, 12' ish ceiling.  Older Klipsch, SS amp, and a 2 table mix deck.....doubtful any 'slip-cueing' would be tolerated...😏

I'll check it out, but fear it's just going to be more loud chatting over the music since it's not 'live'.....which is typ. for any other bar & grill 'round here....🙄

"Don't you boys play any 'nice' music?"
"Turn it DOWN!!!"

'Joe's Garage: Volume 1", title track. ;)

+1 for adding a pair of REL subwoofers. I also live in a three story townhouse and my listening space is a mere 9x9x9 converted dining nook. I recently added a pair of REL T/5X subwoofers and the sonic improvement was substantial. Besides improved bass, I experienced better highs, mids, and soundstage. A pair of REL T/5X subs retail for about 1/10th the cost of my Dynaudio stand mount speakers which makes it the best bang for buck upgrade I have made. Feel free to check out my virtual system to see how little space the REL T/5Xs take.
