I am looking for a crossover with the lowest frequency possible. What are the makes and model numbers of the crossovers with lowest frequency possible? I have a Coustic right now, and it goes down to 32Hz. Thanks for your help.

You can adjust almost any crossover to below human hearing, either by turning off a subsonic filter, running low pass or full-range instead of high pass, or removing a capacitor. If there's nothing blocking or filtering the lows you'll get freqs as low as your music source is capable of playing. What is it you're trying to do? Are you looking for a subsonic filter and not a crossover?

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

but stev is right! your coustic at 35 HZ its not soppose to let any thing higher than 35hz pass what ever your disc or head unit. is if YOUR HU OR DISC goes down to 10 hz then so will the x-over... in theory

Basically, I am doing a project on low frequencies. I just need a crossover with very low frequecies to accomplish this. That's all. Nothing special.

Most amps have built in crossovers, so as long as you set it to low pass, it will pretty much allow all frequencies below the crossover point to pass unharmed. If it has a subsonic filter (blocks all frequencies below this point to protect the speakers being driven) you'll need to turn it off. That being said, your speaker system will need to be able to withstand the abuse you put it through.

I hope you're not trying to recreate the MythBusters experiment.

My ex once told me I have a perfect face for radio.
