I previously owned Thiel 2 2 speakers. These speakers are time and phase coherent and thus needs proper placement and seating to get the best out of them. I now own Thiel 3.6 and you can refer to one of my previous posts for details here:https://forum.audiogon.com/discussions/how-far-away-from-your-speakers-are-you/post?postid=1917078#1...
Thiel speakers use first-order cross over networks and drivers are vertically aligned so that direct sound waves from the three drivers arrive at listening position at the same time. Thiel 3.6 user manual says chair/sweet spot should be at least 8’ from the speakers for this to happen.I would assume 2.4s would require similar set up.
Once you move your speakers 2 ft from front wall, your seating position is almost close to the back wall assuming you are seated at least 8 ft from the speakers. So you are going to get back wall reflections in addition to the side-wall reflections. Depending on room height 8 to 10 ft, there may be even reflections from the top.
I suggest you look for room treatment. Another option is a toe-in if you have not done already. I suggest you keep both speakers same distance from your seating position. Seating height is another factor to consider. Your Thiel 2.4 manual should give you a pretty good description of how to set this up. These speakers need room to breath and muscle amplifiers to drive to their capacity.
My final recommendation is to try a good solid state amp with plenty of current capacity at 4 ohms. From Stereophile review:
Good luck!

My final recommendation is to try a good solid state amp with plenty of current capacity at 4 ohms. From Stereophile review:
its impedance plot (fig.1) indicates that the CS2.4 demands a lot of current from amplifiers. Not only does its impedance drop to 2.73 ohms at 600Hz, but it stays significantly below 4 ohms from 100Hz to 50kHz, and there is a difficult combination of 4.5 ohms magnitude and –45° electrical phase angle at 80Hz. Thiel CS2.4 owners should make sure they have a good 4 ohm–rated amplifier to drive this speaker. that the CS2.4 demands a lot of current from amplifiers.
