6. rk Tweeter should be connected to either woofer or mid range driver 6dB Oct o via dividing network Use as high quality components as possible e ooe for the dividing network If you used poor quality components for 9 2uF or less the network the sound would be drastically deteriorated and Input Attenuator 0 distorted We recommend using Fostex network components and attenuator model R80B If you use 6dB Oct network it is recommended to use a capacitor whose capacity 1s 2 2uF or less Use a high quality film capacitor Caution It is not good to connect a tweeter directly to an amplifier Doing so would cause a break of voice coil wire and buzz sound Please 12dB Oct connect a tweeter via the dividing network CASES ONE ERUEN eae 7 me 5 000Hz 2 2 0 3 7 000Hz eo 0 18 10 000Hz 1 0 0 14 Practical Application FE206En FT17H BK206En This is an example of the FE206En installed in the back loaded horn box BK206En adding an FT17H as plus one tweeter The network consists of one piece of film type capacitor connected in series and it offers 6dB Oct filtering We recommend the value of capacitor as 1uF Connect the capacitor to FE206En in phase Locate the FT17H on the top of BK206En enclosure and about 45 mm retracted position from the BK206En baffle board i e measure the distance at the flat surface of FT17H outer horn This positioning will make smooth association of main speaker and tweeter We recommend
7. the use of tweeter base when locating the FT17H Please refer to the tweeter base drawing below
