How to wire 6.5 and tweeters with no crossovers

Recommended Posts

Alright so I recently purchased some component speakers off ebay. There Morel Maximo 6.5s.

One of the crossovers is defective and the person wont exchange it or give me a refund, even though on the ad it says theres a 1 year warrenty. Can some one help me figure a way to wire the speakers without a crossover thanks.

Do you have an active capable amp?

yeah im running a kicker 650.4 on them, I also have a question about the amp tuning the speakers seem to have a muffed sound if that makes any sense.

Just a thought here: Why not try to repair the broken crossover? Many times there is just a broken solder joint on the circuit board due to rough handling during shipping; inductors are heavy components and a hard hit that causes lateral motion of the board can shear something like this off. Over the years I have repaired many pro audio type speakers used in concert audio reinforcement with this type of problem. Sometimes it is just a defective solder joint that once touched with a hot soldering iron it re-flows and gets a solid connection to the circuit board again. Marginal quality solder joints sometimes happen during modern electronics manufacturing and sometimes still manage to get through the QC process. :blackeye:

 

A quick look at the Morel website for this model gives the specs as a crossover point of 3500Hz and a -12dB spec for the woofer and tweeter, which (I guess) would make this a 2nd Order type passive crossover. Given that, I would suspect that the crossover is quite simple containing only a capacitor and inductor for each of the drivers. There can be an impedance-correcting network for the woofer that is called a "Zobel Network", but since there's nothing mentioned in the Morel literature I assume there isn't one in these crossovers.

 

Here's a web page that shows some passive designs with various crossover "orders" and how they are wired. Crossover Design Chart and Inductance vs. Frequency Calculator(Low-pass)

 

Hope this helps you somehow!
