Fostex FT17H Horn Super Tweeter

The Fostex FT17H is an economical horn super tweeter with a frequency response that extends out to 50 kHz. The FT17H horn tweeter has a high sensitivity, rated at 98.5 dB / 1W / 1m. The nominal impedance of the FT17H horn tweeter is 8 ohms making the horn tweeters easy to drive even with small amplifiers. The FT17H horn tweeter uses a shielded magnet. The overall weight of the FT17H tweeter is 340 g (0.75 lbs). Included with the horn tweeter are mounting screws and a datasheet.  A gasket comes affixed to the tweeter housing.

The build quality of the Fostex FT17H horn tweeter is good for the price range.  The horn super tweeter offers a crisp high frequency response that extends out well past the audible range.  Provided that a crossover point in-excess of about 10 kHz is used, the performance is very good.  The FT17H is ideal for mounting in an enclosure - front and rear firing.  The FT17H offers high cost performance and is well suited for added that last little bit of sparkle and air to high sensitivity speaker systems. From the Fostex FT17H datasheet a crossover frequency of 5 kHz or more is recommended.  We have had good results with this tweeter using a first-order crossover in the 10 to 15 kHz range.  You can use an L-Pad attenuator to match the tweeter level to your speakers.  The low cost FT17H is ideal for use as a rear mounted super tweeter.
