P-AUDIO LAUTSPRECHER PHT-409 HOCHTONHORN KOMBINATION The P Audio PHT-409 is a small format super tweeter designed for use in two way and three way sound reinforcement designs. The PHT-409 offers extended frequency response to beyond 20 kHz. The high sensitivity of the integrated horn/driver system make the PHT-409 an excellent choice for high frequency reproduction in foreground and background sound reinforcement systems. The 100dB one watt at one meter rating means the product is ideally suited for two way systems where conventional direct radiator tweeters suffer from a loss of sensitivity. The small format 1 inch (25.4mm) diameter diaphragm offers extended bandwidth and extended high frequency piston range performance. This diameter diaphragm is excellent for super tweeter applications or small format upper midrange and super tweeter response. The PHT-409 is constructed from a very rugged glass reinforced ABS resin that offers both a high degree of structural support but also excellent mechanical damping for the device.
