We enjoy pushing the envelope of what is capable in subwoofer transducers so we have developed a 24 inch subwoofer with the musical characteristics of a 12 inch subwoofer but with an abundance of low frequency extension and massive impact. The HS series 24″ mkIII subwoofer is handsomely equipped with all of the features that you’re looking for including two Faraday rings to eliminate eddy currents and lower and linearize inductance, a 10” diameter two-layer nomex spider with double sewn-on flat leads, a 20 mm thick machined aluminum spacer/adapter between the basket and motor, and 4 AWG speaker terminals. Other elements are class leading 38 mm of Xmax and 65 mm of Xmech ensuring plenty of both linear, and peak, travel for deep bass requirements. This unique flexible subwoofer can be utilized in sealed, ported, or infinite baffle applications.
