Is it my crossovers fault?

rukkes · 27th April 2004, 05:26 PM

I have built a pair of speakers with vifa pl18wo and pl27tg drivers,
the sound of them is clean and natural, but there is something wrong with them, they sound tiresome and hollow, maybe it has something to do with the crossover.It is a simple crossover just three parts,the lowpass is a 0,60 mh coil and the highpass is a 4,7 uf cap and a 0,4mh coil, i fear that the x-over creates a "gap"
in the response curve, am i right? any opinion?

Have you tried reversing the phase of the tweeters?

Have you checked polarity of the drivers??

I have made that mistake 2 or 3 times (I'm very lunatic sometimes), one driver was out of phase and this result in bad imaging and weird sound...

You can check them out with a 1.5 volt battery, if you connect the battery + with driver +, the driver should move "out" of the enclosure...
