Trulli Audio TD6.5S Subwoofer

Clear and Loud 
 
Trulli Audio’s TD6.5S (TDS65) brings true sub-bass impact to spaces where traditional subs can’t fit. Built around Trulli’s patented perimeter-driven / ThinDriver™ approach, it’s engineered for fast transients, low distortion, and controlled output—so bass hits with definition instead of blur. With a shallow 2.23" mounting depth, 4-ohm load, and compact sealed-enclosure compatibility (0.1 cu ft / 42 Hz roll-off), it’s a high-performance solution for tight builds that still demand real low end.
