hey, im just running my speakers off my deck..which is find for me(winter beater)

it's just anything below 120 hz makes a horrendous racket


any high freq passive crossovers i've found use rca's....so im assuming you should only use them with an amp


so is there anything i can do putting something inline with speaker wire?
thanks

"bass blockers" are just capacitors you place in line with the + lead. i don't remember which value you need for what frequency. but if you look up bass blocker it should come up with what you need

Yep, I've seen this done in some home tower speakers in place of a more complicated passive crossover. Just a capacitor in line to the speaker.

I was gonna say I prolly only need a capcitor but I didnt wanna look stupid but hey hey hey


i got some googlin too doo

i did some googling 200 micro farad (uFd) @ 100V

should roll everything off at 135 with a 12/db slope

i thinker but should be gooder


thanks

If you only put a cap in line, it's only going to be 6dB / octave, not 12.

Here's some reading for you which also includes a calculator so that you can accurately choose Cap values.

andy600rr where's the reading materials?

indeed, the reading material would be much appreciated.. !!

Damn.... sory guys, forgot to add the link

Here you go..

And the calculator for 6/12/18dB / octave passive values...

i couldnt get the exact one I wanted but I bout a 4 pack of 50 v caps 2 were 220uF and 2 400 uF

i put the 220 in series and it did absoultly nothing...400 did nothing either...so I spliced that wire back together and tried the other (didnt know which one was positive)

but it still did ABSOLUTLY nothing...
