"Disco speaker" crossover question

poynton · 15th June 2009, 09:29 PM

I have been given a pair of "disco speakers", by Soundlab.

They have fitted 4 3" bullet tweeters and 1 horn tweeter 9"x4".
These are all wired in parallel.

The crossover comprises of a series choke for the 12" bass driver and a series 20ohm resistor and 4.7uF cap for the tweeters.

Can the crossover be improved to split mid and hi frequencies?

Yes you would certainly think that could be done but it wouldn't hurt to have a little more info on the drivers before anyone could really help.

Unfortunately, the tweeters are all piezo no-name brand with no markings at all. The 12" is a Fane full range.

In this case leave it as it is. Unless there is some unbalance you need to adjust. Note: Prob. the 12" Fane is a woofer (or bi-cone?) and not a full-range.
