Awesome looking build! Im in the planning stages of a Radia Pro 1.9 build so im very interested in how this turned out for you.

Still some work to do, ready are 3 of 4 subwoofer. one hast to be repainted. I also user FA 502 hypex plate amplifier but i have to admit i did not hear in front. Today i will configure the FA502, at least i will learn how to do it

I suggest you use a 350Hx lower XO point. That way your RD75's will last a longtime. Yes I know others have used XO points as low as 150Hz but that not the best idea if you want the panels to last.

Thanks for the hint regarding the higher XO Point. The subwoofer i have build should easily do it. For me to build them was the easiest part but how to measure and configure the XO will be the hardest part. I still not know enough.

Another Step further..starting to install the FA502 Module , should remove the dust on the bottom plate😉

Another Step forward, finally all Hypex Plateamplifier are installed. Now the Cable for the subwoofer...

looks nice are those originals ? since i am in the progress to make something similar, be it more of a carver style. and single ended. because the top end looks nicer that way 🙂
