800 Hz Low Pass 4 Ohm Crossover

Is it possible to wire this in series to a woofer?

Currently i have it wired in parallel on a 4 ohm woofer with another 4 ohm coaxial speaker in parallel producing a 2 ohm speaker which is undesirable
Asked by: TomSwanberg
Unfortunately no, these can only be wired in parallel.

Frequency matters so,

How low can the frequency go?I want my woofers to be able to be low frequency.
Asked by: tylou
Low frequency can go sub sonic, or below the range of human hearing. The general audio range for us humans is accepted as 20hz to 20 khz. however this is a best average. Life in a noise filled world damages our hearing and can reduce our overall range or other frequencies.The crossover you have picked will allow very low sounds to pass into your woofer. The speaker and your cabinet design will shape what your system produces.

Question About Crossover Frequency

Could I use this for a home theater subwoofer?If not then can you point me to one or the parts to build one.Thank you
Asked by: msm123
Technically yes although 800 Hz is generally far too high of a crossover point for a subwoofer. I would recommend the 80-100 Hz low pass instead.Keep in mind these will not take more than 250 watts, if you need something that will handle more power I would recommend simply going with a subwoofer plate amplifier.

Would two of these, wired in parallel, make it 2 ohms?

And, what would the effect be on the frequency? would it change to 400 or even 1600 hz?Thanks!
Asked by: nathin93
No. That's not how crossover components work. You can use a crossover calculator to determine the parts you need based on the drivers, impedance and crossover point you want. The bigger question is why 2 ohms. This is not good. Designers seek to build 8 ohm speakers to be easy for an amplifier to run. The only exception, for whatever reason, is for subwoofers in car stereos. And in those cases, the amps have electronic crossovers built in. Feel free to elaborate on your design if you need more help.

Would this LPF equate to 400 Hz in an 8-Ohm subwoofer application?

PS, sorry I believe I may have inadvertantly asked this question under the 800Hz 4-Ohm High-Pass Crossver. My Apologies.
Asked by: TheGDog
No, the crossover point would shift UP by one octave if you apply this product to an 8 ohm speaker. For a 400Hz 8 ohm low pass, a 4.5mH inductor and a 35uF capacitor would be indicated. I've linked the appropriate items below for your convenience. Wire the capacitors in parallel to achieve the desired 35uF capacitance.
