Short answer: the JTR Speakers Growler (2015). Its 12-inch ported driver reaches a 130.2dB CEA-2010-A average, nearly matching the class leader for less money than the Chase, which delivers 125.2dB from an 18-inch sealed cabinet. The Growler trades sealed-cabinet room modes for ported room interaction at 45 kg (99.2 lbs), while the Chase is a passive design needing external amplification.

Buy the JTR Speakers Growler (2015) only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the JTR Speakers Captivator 215PRO instead.
