Blocking Treble

Post by tuberadiogeek on Sun Dec 01, 2013 1:00 am

I have a 4 ohm subwoofer I would like to hook up to my Onkyo receiver. Mainly to have to watch movies so I can get the super low tones to rumble nicely. I just want to block the highs going to the sub and have no clue how to block them. Is there a type of cap or resistor I can use? I know to block lows going to tweeters I can use non polar electrolytic caps. Also just to clarify my receiver can handle 4 ohm loads.

Likely, four ohms is a bit too low resistance for the modern equipment. The only thing you can do to block some of the highs is to disconnect the tweeter.

My receiver isn't modern. It 1980's and rated for 4 or 8 ohm. It is full range and I do not want highs getting to the subwoofer possibly damaging the voice coil.

O.K. Didn't know it could handle four ohm. But, not sure I know how to block the highs, and, not positive they would ruine the sub, either.
I'm not sure on that one, but, not sure how it could.

The block of Highs is related to the reactive impedance of a capacitor and or inductor.
A small capacitor in series will allow High frequencies to pass, and of course a large value capacitor will allow lower frequencies to pass, If you put the small capacitor value in parallel then it would short the High frequencies and if you did the same for a large capacitance value in parallel then it would short or bypass the low frequencies.

It would be just the opposite for using inductors.

There are formulas for achieving what you want.
