Hello,
I tried SPX-32M on small reflex box, 4-5 ltr, tuned about 80 hz. These are somehow similar to SPX-30M. Bass was quite insufficient and upper tones were to bright. Theres need to try SPX-32M on TQWT box if it gets better:

Try OB. This his another difficult possibility...
Alignment for a good (response) BR might be difficult but with simulation help might be close to what you expect. I don't know about TQWT, but don't expect to much under 50 Hz either way (from sims).

I'm actually very interested in open baffle. How easy is it to get sounding "good"? I don't need bass as I'll be using them with a subwoofer but I like the idea of designing a front baffle and just leaving the rear open etc. Is it that easy?
It is that easy and for this driver I guess... is better with your config.
Choose a good baffle.
The front panel is in direct relation to the LF, in your case more flexible for the mid-bass, than for lower frequencies FR drivers. The dimensions of this front baffle (and type of U/H frame for the acoustic short circuit) are in relation to the lowest freq. not critical for your first auditions and experiments.
Usually a sub added to the FR makes a tweeter necessary, what for this project (Monacor SPX-30M @15KHz), might not be the case. Have that in mind, you will end up with a 3-Way type loudspeaker.
I don't design OB (note), just fun (I will do it one day...) 😀
