How to use resistance + capcitance to lower fs

[brianpowers27]

How do you use resistance + capcitance to extend bass?

Can I use a simulation to model this?

Answer: Use the PCD. Set a r-c filter in series with the driver after the crossover. Start with a filter around 250uf and 3 ohms of resistance. The capacitance creates a peaking high pass. The peak will give you a little extra low end. The rolloff below the peak will be steeper than before. You will also need to use the resistance to level out the high end.

You need to talk with Daryl.

Fs is a mechanical property. Altering it is accomplished by altering the mass of the cone and other moving parts and the compliance of the suspension. You can mimic a lowering of Fs by electrical means, but it's just that, mimicry.

Thanks for pointing that out. I will update the initial post.
