Finished the building this week, and did some testing Yesterday. I didn't buy a suitable amp for the SKhorn. Originally I wanted a used Crown Itech 12000, since it later will be used in my Hometheather, together with the other Crown amps I got there, but the price is a bit high still. And Powersoft is just crazy expensive, even those with some thousand hours on them. I also looked at a SpeakerPower SP1-6000, but it does not have a good enough EQ/DSP, I think.
So, we did the testing with one of my old Crown Itech 6000. It does not get the IPALs going very high in volume, but high enough for a little test. Here are som pics and a videolink. Got two friends to help me testing, and it was fun (and still a bit too cold outside...)
