testing a crossover

The best way I know of to test a crossover is to generate an impedance graph. You can use DATS V2 (or is it now up to V3) or you can build a jig and use Room EQ Wizard’s app for this.

But... if you are bi-amping it is possible the two crossover sections are not properly separated. If the voltage in one section can touch the voltage in another, at all then you can cause the amps to fight each other. If the internal crossover is completely separated, including separate grounds internally then no problem.

OTOH, if the ground is not separated internally and 1 amp has reversed outputs or balanced outputs then you run into the problem above.

@likklegerry - Anymore info from you? Are you using internal passive crossovers?

Hi Guys,thankyou so much for all your help,but i still dont see a solution to this problem,in my opinion there is shorts in both xos,please see below-

             LEFT SPEAKER                                  /
 RIGHT SPEAKER
                speaker terminals with everything connected on both speakers

     MID/HIGH        0.0 ohms                             /
    MID/HIGH    0.0 ohms
       BASS           7.9 Ohms                             /
       bass          6.8Ohms

                                      DRIVER TEST DISCONNECTED FROM X OVER
          TWEETER 8 OHMS                                 /
    7.9 OHMS
              MID 6.3 OHMS                                   /
         6.2 OHMS
             BASS  6.1 OHMS                                /
       6.0 OHMS

     CONTINUITY TEST ON X-OVER WITH DRIVERS REMOVED USING DIODE FUNCTION
                                             between positive and
negative on x over
         HF                  000.2 {dead short}
         /       000.2 {dead short}
         MF                  000.5
              /       000.5
         LF                     OL.
                /        OL.
MID HIGH INPUT IP     OL.                                 /
                OL.
   BASS INPUT            OL.                                 /
                   OL.
                                                  OL. BEING NO CONTINUITY

                               TEST TESTED AT/ON X-OVER SPEAKERS CONNECTED OHMS

         HF 0.0002 OHMS                                      /
              0.002 OHMS
         MF 0.0001 OHMS                                      /
               2.0 OHMS
         LF   6.4 OHMS                                          /
                   6.3 OHMS
ive also now removed one lead from all the caps on one xo,and tested them with a cap meter,all caps are the correct uf ,within spec,can anyone tell me where to go from here,
thankyou again for all your kind help.regards Mark

i am using internal xo,which came with the speakers
all tests done with power amps disconnected.
the problem{ going pop{broken}only happens when the speakers are driven in bi-amp config,and its the amp which is driving the high/mid drivers that blows up .
when using only one amp,in bi-wire config,everything works,all be it the sounds quality is slightly off,but i would have thought that to be ok,that why i bi-amp,for better sound quality.
to add to this,i changed out the xo caps for better ones two years ago,and after fitting them ,i tested the input speaker terminals for the correct ohms reading and all was good,but something has changed.
regards Mark

i would also upload some photos, but as this is my first ever use on this site,im not sure how to do this, any help appreciated,
mark
