The professional sound reinforcement loudspeaker Pro X 6 offers absolutely uncolored sound and very precise sonic dispersion patterns. At the same time, the physical appearance of the speaker is as unobstrusive as possible, and extremely compact.
The multifunctional housing and the rotatable 90° x 60° horn together offer new opportunities to solve even the acustically most challenging sound reinforcement problems. The sides of the cabinet are angled in such a way that it can be mounted as a cluster at any angle from 120° to 360°, or using it as a floor monitor.

To handle the low frequency range, a 61/2" LF driver was developed specifically for this cabinet. This woofer has an extremely long, linear stroke which enables it to reproduce even very low frequencies at high sound pressure levels with minimum distortion. The high frequency driver was developed, as 1" tweeter which significantly extends the usable range both upward and downward. This range is starting at 1.6 kHz, and is projected precisely by the horn at angles of 90° and 60°. A ring-shaped diaphragm produces a wealth of sonic detail with extremely low distortion even at high levels.

In an extensive series of tests using advanced computer simulation and measurement techniques, KLEIN + HUMMEL has developed a constant directivity horn possessing no diffractive edges and yielding a dispersion of precisely 90° by 60° above 1.5 kHz. The highly refined horn geometry plays an essential role in reproducing superbly balanced music and intelligible speech. The cabinet of the Pro X 6 is constructed of 8-ply birch plywood and is coated with a scratch-resistant, dark grey or white paint. Each cabinet has a great variety of mounting adapters.

The Pro X 6 is available in a low impedance version N (16 Ohms), which permits the connection of up to 4 units to a 4 Ohms amplifier and a 100 V version H, featuring a high quality transformer with a full/half power switch. When lower frequencies are needed, the Pro X Sub S subwoofer together with the Pro X 6 form a high quality, very compact PA system. This can be driven passively with a crossover network built into the subwoofer itself. One can opt for active operation by using one of KLEIN + HUMMEL's high performance power amplifiers with optional controller modules. These system specific modular cards can handle functions of limiter, system equalization and active crossover.
