"Hi Guys,
heard them today, best staging and disperation I ever heard, low mid/mid and high is perfect...,and today I compared speakers up to 48000$. Best is they can play loud too. Was speechless about this performance. Had time to talk to Bönnings in person about the SLS.
Yes the mid/high are the tangbands-W31797S in parallel (2 Ohm!!) only with 1 MKP at 300Hz HP, the fullrange on the side makes 80 to rougly 6000Hz (no crossover!) and 2 Woofer with the Omnes DSP active at/till 80Hz. Fullrange/Woofer are all the same one, a Monacor loudspeaker, but I don't know which one but what he said they are 17cm and till 6000hz. Can somebody help, PLEASE...found it, it is the SPH-176 Monacor, fits perfect from RE 6.6Ohm=3.3 Ohm (see descrition), look, TSP for TML, measurements....
Wanna build them myself because 10000 is a joke, the chassis cost not more then 500$ and the sub section with the TML is not necessary for this awesome sound. The Tangbands and the side Fullrange Monacor rocks and from 80hz downwards I can also use a very good closed impulscorrected sub with 8 inch Woofers per side to have a good performance between 80 and 30Hz...
So I don't need the complex CNC-machined inside, the same outside design and measures are enough, which are already given. If I want I could even find this out because I have fotos from the inside, the cutout dimension of the speakers and the outside measurements. so if I zoom the foto till I have the correct outside dimensions I can even rebuild the TML."
