Short answer: the Danley Sound Labs DTS10 for output, the Chase SS18.1 if weight matters. The DTS10’s dual 12-inch tapped horn delivers a 129.6dB CEA-2010-A average and remains in current production, but it needs an external amplifier and weighs an extreme 129 kg (284.4 lbs) in a very large cabinet. The 18-inch Chase delivers 125.2dB from a lighter 41 kg (90.4 lbs) sealed cabinet, though it too is passive with sealed-cabinet room modes.

Buy the Danley Sound Labs DTS10. It is rated higher for sound quality; the Chase Home Theater SS18.1 is no longer sold new.
