Jak w temacie TQWT/TQWP/BiB projekty, doświadczenia..
Zapraszam do dyskusji
Wklejania zdęć..
Na początek miły projekcik na:

Tweeter driver: Vifa D27TG-35-06 ; 25 mm dome (called HT-275D2 in NL)
L1 = 2,2 mH air coil
L2 = 0,39 mH air coil
C1 = 8,2 uF bipolar capacitor
C2 = 8,2 uF bipolar capacitor
C3 = 8,2 uF capacitor MKP
R1 = 5,6 Ohm/ 5 watt resistor
R2 = 2,7 Ohm/ 5 watt resistor
Technical details
Principle: Terminated line
Impedance: 6 Ohm
Sensivity: 88 dB (2,83 V/ 1 m)
