Fuctional Difference Between Front And Rear Speakers?

[Eric Cheung]

I read from the FAQ that front speakers are 5.5 inches and rear speakers are 6x9. Are the front and rear speakers fuctionally the same or different?

I would have thought that the front speakers are more specialised for human voice and the rear speakers are more specialised for bass due to the bigger size of the rear speakers. Are I correct in thinking this way?

Yes

[Eric Cheung]

Yes

Thanks for the confirmation. I am thinking of putting in crossovers for the front and rear speakers.

They are not normal 4 ohm speakers and as such will need a new amp if you are replacing them with aftermarket ones.

Thanks for the note. My car did not come with the stock amp when I bought it. The speakers are powered by a Sony head unit without external amp. That is why I want to put in crossovers to separete the frequencies for the tweet, front and rear speakers to improve the sound clarity.

The sony head unit should have a crossover in it. The front & rear outputs are not driven with the same signal. Unless that's just ike a 10 year old + headunit, even the cheapest crap ones are all multi-channel.

Don't the stock tweeters have a crossover coming off the door speakers? sk? I don't remember.

Bro if you want sound clarity. Time for new speakers. ;)

The tweeter had a minor passive crossover made up of a cap and a resistor to raise hrz but that was all.

Oh really? I didn't know that. I thought the front and rear outputs were the same. No wonder the rear speakers seem to sound more bass even without the external crossovers. Thanks for that.

I have finished putting in the passive crossovers:

- a 4.5k Hz 2nd order high pass for the tweets (by-passed the original built-in 2.2uF cap of the tweets which act as the 1st order high pass crossover)

- a 800Hz-4.5k band pass for the front speakers

- a 800Hz low pass for the rear speakers

- a 250Hz low pass for the sub

I'm not sure if this is a good arrangement. But now it does sound with better clarity.

That's cool.
