P-AUDIO LAUTSPRECHER HT-411 HOCHTONHORN KOMBINATION The PHT-411 is a rectangular geometry high frequency integrated horn and driver that features a 100 degree horizontal by 40 degree vertical radiation pattern. This design features a constant directivity style horn and offers a rated bandwidth of 2kHz to beyond 16kHz. The PHT-411 offers a very high sensitivity of 105dB when measured with a one watt input at a distance of one meter making the device an excellent mid range and ultra high frequency device in two way sound reinforcement systems. The PHT-411 is ideal when used with a 12 inch or 15 inch low frequency transducer in a two way design. The integrated horn and driver is used in many professional two way designs. The PHT-411 utilizes a small format 1 inch (25.4mm) diameter diaphragm assembly that is optimized for extended piston range response The PHT-411 is ideal as a high frequency device for portable high performance sound reinforcement systems. The device is constructed of a very rigid glass reinforced ABS resin that offers both superior structural support as well as excellent mechanical damping.
