Apologies to Ked
Well when i was a part of a sound system (Exodus), we ran a mix of sealed boxes, w- bins and scoops for bass.
When i researched the best subwoofers to run outside in my amphitheatre and complementing my EAW thx-spec full range cabinets the consensus on the pro sound forum was either the Danley Labhorn or EAW's bh883, aka Big Bertha aka Levan, the mahoosive bass horns that underpinned the Ministry of Sound's rig at the time it was considered the best dance rig in the world
So i hoped that horns could provide the sound i am looking for, but maybe supplemented with sealed boxes.
Which the Velodynes are, of course
Also the Pnoe have a further advantage....weighing 60kg or thereabouts, and with high efficiency and good power handling, and with a minor structural rejigging chez gav, the Pnoe could also double as outside speakers for the amphitheatre.
Where they are now sited is just in front of patio windows, the other side of the glass is a small patio commanding the amphitheatre so it wouldnt be too hard to shuffle them out of the patio doors, turn 180 degrees and i have sounds outside.....without going to the considerable trouble of building outside enclosures for the vending machine sized EAW 4973f's, and without requiring the 14 channels of pro sound amplification, plus crossovers plus dsp, to drive two 4973f's and four bh883's
