Схема подключения crossover network power acoustik


The reason for going woofer to tweeter is so that the HPF is before the LPF for each bandpass speaker. See the Crossover Guide for explanations on the different types of these components (Mylar vs. polypropylene capacitors…). In the end, it is about how much money you want to spend, which should be no more than half the cost of the drivers. This is important, so take note of it. Remember that it is a base 2 logarithmic scale. The next step in designing the crossover circuit is to design the l-pads to equalize the different driver sensitivities. 2db needs to be removed from the tweeter, and 1db from the woofer. This is the complete circuit for the 3-way system.


Note, this sample crossover makes use of many of the calculators found on the menu on the left. Ordering foil inductors one at a time can get expensive. From the listener’s perspective, if all goes well, the sound quality should remain exactly the same. Any piece of wood will work as a mounting board. The combination of both sources results in a dipolar characteristic where the main energy is radiated along the walls as indicated by the dotted line. For many years, my stereo loudspeakers used 12-inch Altec-Lansing 419-8B biflex woofers and Altec 3000H horns in seven cubic foot (internal volume), custom built, bass reflex enclosures.

You also get four different mono and stereo output operating modes, all with individual crossover filter types (Butterworth, Bessel and Linkwitz-Riley) with selectable roll-off characteristics from 6 to 48 dB/octave. The Crossover Calculator was used to determine the crossover components. This last point is sweetened by the fact that it is the most extreme audiophiles, often with more money than electronics knowledge, who are likely to bi-wire and buy the most expensive speaker cables. All four amplifier channels are fed the same, full range, signal from the pre-amp.
