Yes your speakers are a very weak link. Lots of distortion and can’t even play at 90 dB SPL without compression and the deviation from linearity plots look absolutely awful at 95 dB SPL. Also that nasty peak just above 2KHz screams that something is very badly wrong with this design. I would steer clear of Monitor Audio in future.
Best get rid of them as soon as you can. As an engineer these terrible measurements should be quite easy to understand. THD + N a mere 30 dB down in the mid range is appalling (my speakers THD+N are -70 dB SPL which is a target you should at least aim for within your budget constraints).

Speakers are the most important part of your setup - even with astronomical expenditures on the speakers and your audio room - the room and speakers will likely remain the weakest link in any setup.
