Has anyone tried this? I'm about to set up my speakers and that and I was thinking of doing this to my main speakers. I got my front and rear speakers running off of the headunit and my sub running off the amp and I think the sound would be good if my main speakers had there bass blocked off.

I'm just wondering has anyone tried this?

They're just passive crossovers. They do an OK job, but if your head unit cost more than $250 or so, it should have the ability to filter the frequencies you choose.

this is just a crude high pass filter. just like what they talked about in that article with a sub having a crude lowpass.

only problem I have is their info is one size fits all and this can also cause other problems with phase and so forth.

but also if you are causing yoru speakers to bottom out you either have bad speakers for your needs or your doing something wrong.

High pass filter and low pass filter. high pass is for your bass. low pass is like treble. must head units have both and many amp's do to.

Just to let you know, you've got that backward. A low pass filter allows low frequencies to get to the speaker, so it's for the bass. A high pass filter does the same for high frequencies, so it is for the mids and tweets.

That's similar to my set-up, except no need for the passive crossovers. My headunit already comes equipped with the better option of using it's active crossovers.

I would prefer to filter the appropriate frequencies prior to sending them to an amplifier and then to the speaker (although many, if not most, amplifiers also come with active crossovers). Why have an amp inefficiently wasting energy boosting the complete audio spectrum when only a portion of it is needed for any certain particular speaker.
