Who can build F.Wiechen for me?

Hello guys, next week I get my Sinfoni. So nice and good. but according to some people (I personally have no experience and zero plan of Aktiv Betrieb) say that my HU (9812) does not provide full turnouts to actively operate my scans at the Sinfoni. So now I have made myself smart like the scans at the “best” to operate. Quotation: Have separated my scans at approx. 2500Hz with 6.8μF / 0.27mH / 10μF (i.e. 18dB), then in series still nen 2.2 Ohm MOX around the same practice increase of the 2904/60000 from 10kHz to contain something. Skin also great. Zitan end Would someone be willing to build such a turnout only for the HTs? Please. Of course for small pay. Greetings oli
