I only did some "rule of thumb" calculations for the TML speakers and the rest was trial & error. Because of the small size I had to make some compromises and you can clearly hear that if you run the speakers off a normal AMP. With a 4-channel DSP AMP however you're able to tune everything and making them sound really great. That's basically the same what manufactures of small Boomboxes / Active Speakers are doing to get a better sound out of a small enclosure.
Speaking of the Amp/DSP, the ISUDAR DA408 arrived and since it's usually meant for Car installation I've started to mod it a little bit...
first of all I added a small power switch because obviously I have no ACC/ignition signal at home to turn it on/off...

secondly I modified the cable harness...

using some sleeves and GX12 connectors that looks much better for home use... as for the power supply I am using a second hand 12V 6A brick that I shot on ebay for 3,- EUR...

all wired up...

I also ordered a small wired remote control for the DA408... btw, the AMP supports Bluetooth, Chinch, USB and even Optical inputs

the parameters such as x-over, EQ, phase, delay, etc can be configured "on the fly" via PC (USB) or Android APP (Bluetooth)... unfortunately the Android APP does not work very well...

but the PC software does a good job and it's really fun to play around with while fine tuning the sound of the speakers... It also allows to program 6 different presets to the Amp which then can be activated using the remote control... very nice!
