As you all know, twelve midwoofers per speaker is just not enough to get you all the way down to 20Hz, so Goebel decided to use an additional two meter woofer tower with sixteen more drivers.
Having a total of 40 (!) woofers requires some serious amplification. This was not an issue as Analog Domain Audio brought some of their top amplifiers bursting a few thousand Watts each. As a source, a full stack of MSB electronics Diamond series was implemented, controlled by the omnipresent during the show iPad. Cables were naturally Goebel’s own Lacorde series.
Sound on Billy Idol’s “Sweet Sixteen” was as expected big but bass was too overwhelming and showed the limits of the room in terms of standing waves, in other words boomy.
