TH18 Tapped Horns and KV2 ESD12 testing

Testing my newly built TH-18 tapped horn subwoofers outside. Gear is as follows: -2x TH-18 tapped horns with B&C SW115 4ohm woofers -2x KV2 ESD12 passive mains -Crown Itech 6000 for subs (2 x 3000w at 4ohms) -Crown Itech 4000 for mains (2 x 2000w at 4ohms) Mains are high passed at 90hz 24db/octave butterworth, subs low passed at 80hz 24db/oct butterworth and high passed the same at 28hz, 5.8ms delay on mains, NO EQ! This is an extremely powerful system with the tightest and most musical bass I've ever heard outside! The KV2's sound very smooth and clear. The subs -3dB point is about 36hz according to my measurements. The track playing is Jim Keltner - Drum Improvisation. The SPL meter is positioned 5m away. You can see peaks of 116dBC on the kick drum hits which would be approx 130dB at 1m! My phone's mic is distorting. Could definitely feel a punch in the chest and met a neighbour a few houses away! Thanks to Martin/Xoc1 and the others on diyaudio.com for designing this kickass PA sub!
