Default New 4 way active system finished

Here is a 4 way active system I finally finished. The sub contains two peerless sls-8 driver in ported enclosure. Ports are at the back. Filter for the sub kicks in at 100Hz. The upper part is open baffle. For optical reasons the back of the drivers is covered by 10mm basotec in a wooden frame. Frequency range from 80Hz-250Hz is covered by a PHL2460 which is one of the most neutral drivers I ever used. Above 250Hz works a Thiel SCS3 coaxial driver. Tweeter takes over at 2000Hz.
The upper part with the Thiel can be replaced by two other versions. One containing a Manger MSW and a third one with an Eton 5'' and a 25mm Visaton ceramic tweeter. But in fact the Thiel delivers the best trade of between liearity and imaging in my opinion.
Crossover is implemented in a Najda DSP and music is coming from a heavily modified Sony CD player or most of the time streamed from a Raspberry PI 3.
Sub section is powered by two IRS2092 module and the open baffle section by 12 LM3886 (6 modules with 2 LM3886 in parallel each). The Thiel is nominally rated 4 ohms but comes down to 3 ohms partially. Therefor I decided to use LM3886 in parallel. In the future I plan to build 6 CFA amps
for the open baffle section.
