DCR Checkpoints for SDA's

[Toolfan66]

I just finished putting my 1.2tl's back together. Thought I would check the DCR values, on the test data sheet in the SDA sticky under 1.2/1.2tl models under R1 and R3 it says 2.2 for both right and left speaker mine measures 1.5 any reason I should be concerned??

All the others are dead nuts or very close the 3.0 is on the money and the 3.6 is measuring 3.5 and 0.0 is just that 0.0


Thanks!!

Anyone???

Did you do the crossovers?

[Toolfan66]

Yes. I did them awhile back when I got the boards from Ray..

Hello Larry,
If you look at the crossover schematic for the 1.2TL the measurements are dealing with the 16mH inductor that is the first thing pin 2 is connected to. Both of the tests are measuring the path through this inductor. Was this one of the parts you replaced?

Yes with a Northcreek inductor, Funny you should ask as that was the first thing that popped in my head when I did the tests..

It is possible the DC resistance of the coil is less than the original. This is assuming the coils of the MW6511 are within spec.

Yes, that's North Creek's claim to fame: http://www.northcreekmusic.com/COILS.html
