KPT-904-B
The KPT-904 is a mid-sized screen and stage loudspeaker system, especially suited for stadium seating. Higher frequencies are handled by the KPT-904-HF, which uses the KDE-75-8P 3-inch titanium diaphragm compression driver mated to the K-691 horn, while bass punch is provided by the KPT-904-LF dual 15-inch low-frequency cabinet. This advanced Tractrix horn geometry and compression driver technology create a large soundstage with well-defined imaging for a genuine, lifelike sound. The B version is the bi-amp configuration without a passive processor.
