Product Information

capacitor 1 = 0.1125 6 × 3000 = 6.25 × 1 0 − 6 F = 6.25 μF \text{capacitor}_1 = \frac{0.1125}{6 \times 3000} = 6.25 \times 10 One solution to this problem is to split up the signal coming from the amplifier according to the signal frequency. Then, for example, low-frequency signals will go to the woofer and high-frequency signals to the tweeter. A combination of the right capacitors and inductors creates filters that only allow the right range of frequencies to go to the correct speaker (or driver). Has a wide choice of filter characteristics, including Butterwork, Bessel, Linkwitz, and Chebyshev.

In the 2-way mode, the calculator uses the impedance of your tweeter and woofer to produce a 2-way speaker crossover design. By choosing three speakers, it becomes a 3-way crossover calculator, in case you also want to incorporate a midrange speaker into your design. Enter the crossover frequency(s). For a two-speaker setup, look up the frequency response ranges of the speakers and choose a frequency that is covered by both speakers.If you are new to the field of hi-fi speaker design, you might be wondering, why we can't just use one speaker? After all, you will probably find devices around your home that only have a single speaker, such as a small portable radio or your mobile phone. But do they sound great at all frequencies? capacitor 1 = 0.1125 tweeter impedance × crossover frequency capacitor 2 = 0.1125 woofer impedance × crossover frequency inductor 1 = 0.2251 × tweeter impedance crossoverfrequency inductor 1 = 0.2251 × woofer impedance crossoverfrequency \small

However, it still allows signals to go to the wrong speaker (due to the low filter slope value), so the damage could yet be done to the tweeter if it receives a significant signal with a lower frequency than it can handle. For a 2-way crossover design, you have a low-pass crossover filter and a high-pass crossover filter. A low-pass filter lets through frequencies less than a certain amount, while a high-pass filter only lets higher frequencies through. The crossover frequency is where the low-pass filter starts to fade, and the high-pass filter starts to increase the amplitude of the signal. A typical value for a 2-way crossover frequency is 2000-3000 Hz.Let's say we have a tweeter impedance of 6 Ohms, a woofer impedance of 4 Ohms, and a crossover frequency between the two of 3000 Hz. You would then calculate each component as: The solution is to have two or three (maybe more, but these are less common) specialist speakers inside each speaker unit. A speaker that outputs high frequencies is called a tweeter, and one that produces low frequencies is called a woofer. When designing for three speakers, you'll need to set a low and a high crossover frequency using the same method. Note that you can only choose a spread between these frequencies of either 3 or 3.4 octaves.
