3rd Demo - Dual W8Q-1071F Tapped Horn

One more excursion video of the dual Tang Band 8x12" 16Hz tapped horn. After discovering a loose screw on one of the drivers in the last video, I decided to re-test using Flight of the Phoenix at reference levels to see what changed now that the air leak at the front driver is gone. This is the result. Power provided by a bridged QSC RMX-1850HD (about 1100W), highpassed at 10Hz. Note that the SPL meter is set on its highest setting, recording peaks in excess of 126dB. This amounts to about 122dB peaks at my listening position. The distortion you hear is massive amounts of low frequency energy overwhelming the camera's microphone. This thing was literally vibrating the concrete floor around the horn mouth.

@2009thread1 Nice - hope it works out well

im building a much smaller tapped horn with two 6.5" kevlar drivers

@gnativerson 74" x 42" x 17.5" - it's a big one. I've redesigned it to use CSS SDX10 drivers - that will get the size down enough to make it a little more practical. It took almost 4 sheets of plywood to build this one, and the redesign cuts down the material needed to 3 sheets. As a side bonus, the new one will get even louder due to the SDX10 having higher excursion.

impressive - what are external dimensions? how much material did it take to build?
