Bass Blockers?

Okay, installed new pioneers to the dash and rear pillars. Which bass blockers should I purchase? 150hz/4ohm, 300hz/4ohm, 600hz/4ohm, or 800hz/4ohm.

Re: Bass Blockers?

R u just running the speakers off the HU? Also did you use 3.5's? If your just powering with the HU id go with 600hz if you have an amp or something providing more power possibly the 800 hz but the 600hz should work fine.

Re: Bass Blockers?

Well, the 800 hz are for a higher powered system. I think the 600 hz would work fine. But if there isnt a price difference and you know your going to add the amp just grab the 800 hz. Not much of a difference either way though.

Re: Bass Blockers?

I wouldn't say that the power of the system has anything to do with it. The capacitor blocks the frequencies below the level indicated. If the full range of the audio signal is 20-20k Hz, then the 800 capacitor will only allow the frequencies in the 800-20k range to reach the speaker. It blocks everything from 20-800. I would go with the higher value (probably even higher than 800), so that the speaker works in a narrower range. A speaker that small isn't intended to pump out bass or mid-bass frequencies.

I didn't do much searching, but this site shows that their caps block at 2.8k for a 3.5" speaker.

Re: Bass Blockers?

800 hz will work fine for ya. It will keep the frequencies ya dont want out. So, dont worry about it ya made a purchase that will work out fine for ya. I have a higher powered system and I only got the 600hz and I get a good crisp clean sound out of my smaller speakers with little bass coming through. So, no worry of distortion.

Re: Bass Blockers?

If you plan on putting an amp on them - go with the 800Hz ones. Bass Blockers (in line non-polarized capacitors) only provide a 6dB/Octave crossover. Which means that every frequency octave below 800Hz will be successively 6dB quieter. They dont just block the frequencies below the crossover point.

So they are not really bass blockers..they are sound limiters...interesting?

I went with the 600hz/4ohm with the unamplified stock head unit.

So it's just tapered off instead of a sharp cutoff at 800. That makes sense. I'd wondered about that, thanks for the explanation.
