Less than 20-inches in depth, it is also one of the smallest speakers in its performance category. Based on the proven KPT-904-LF dual 15-inch bass unit, the KPT-435-N delivers powerful bass from a shallow cabinet that is just 17.75 inches deep. In order to the reproduce critical dialogue range, this system also features the new KPT-335 HF/MF, which consists of a K-510 Tractrix® Horn, two-inch throated compression driver and the K-703 horn with a 1.75-inch titanium diaphragm. It is perfect for exhibitors who want to utilize a fully passive or bi-amp three-way system in their auditoriums.
