Are there in-line HPF's?

[justafifteen 10+ year member]

Well my front-stage amp doesn't have a HPF, only a LPF. I don't want my front speakers playing below ~80hz, so is there a high-pass filter that I can buy that will just plug into the RCA's or something?

Speakers & amp are in my signature down there

I would think an electronic xover would fix that

A Harrison Labs FMOD is exactly what you describe, but yes, an adjustable electronic crossover is the better solution...

Well it's a 2ch that's 60 x 2 so I'm pretty sure it's meant for speakers, but it can also do 300 x 1 i think, so both. It only has a built-in LPF and not a HPF //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

even cheaper - you can just put a capacitor in series with the speaker - also known as bass blockers. but it's only 6db/octave while the FMODS are 12dB/octave and are before the speaker amp. if you use a bass blocker, you need to go a bit higher in frequency - like around 120Hz since they will still have some output at 80Hz. With 12db/oct you can go to 100Hz or 80Hz.

but pony up the money for your speakers - including their amp and crossover. You shouldn't spend more money on bass than you do for speakers, in fact, it should be the other way around.

You can go the non-polarized electrolitic capacitor route but in many cases if it is just the right size for the amount of wattage you want to run and you slightly clip the signal it will blow like a little 22cal. bullet, so if you do go that route find one meant for up to 220v in it's application
