I have an old focal 5V2 polyglass 2 way component set from my car that is short one tweeter due to damage by a friend with his lacross stick. The speakers and single tweeter have been gathering dust in my closet for a while, so I decided to use them for a center speaker in my home theater setup. I built a vented enclosure for them using an online calculator for the dimensions. It's divided into two cavities so that each woofer has its own sealed cavity of the proper dimensions and port size.
The component set has a 5.25" polyglass woofer, passive crossover and TN45 tweeter. I can't find a datasheet on the tweeter but from online research it appears to be a 4ohm tweeter and not 8ohm like some of the newer Focal tweeters.
The issue I have is how to hook it up. My receiver is an Onky HTRC-260 requiring a minimum 6ohm impedance. Currently i have it hooked up so that one woofer and the tweeter go into a passive crossover and the crossover input is hooked up in series with the second woofer.
This setup produces decent sound, but the tweeter barely has any sound coming from it. I assume that is because at the high frequencies, the woofer has about 25 ohms impedance and the tweeter is only 4 ohms, so only 1/6 of the power is going to the tweeter and the other 5/6 to the woofer.
Would it be possible to use the second crossover and hook the woofer up to the low-pass and a 4 ohm resistor up to the high pass and then hook the two crossovers in series. Or is my only option to build a custom crossover for the set? I would like to run what i got if possible to keep the costs low.
I'm looking for any help i can get, cause i haven't found information on a setup like this online. Thanks.
