Capacitors

Oh, OK, this makes more sense.  The 26 uF is on the mid range.

Be VERY careful replacing the 8uF that is in parallel on the mid. I'd need to do a full analysis, but if that has 2 Ohms or so of ESR, you don't want to remove it.

Best,

Of course, ideally you measure the ESR of each cap before replacing.

You can do this with a DATS unit or using Room EQ Wizard with a custom jig.

The 26 uF in the high pass doesn't make a lot of sense though. Are you sure?

Depends how old, and where.

In series = Safe
Going to ground = Dangerous
Old = High ESR
Newer = Low ESR


If you are replacing a series cap, relatively ( < 10 years) new, you are fine.

If the cap is old, it probably has higher ESR, and that should be taken into account, but in series it's not much of a problem.
The problem is in shunts ( 2nd component in low pass)  where loosing a couple of ohms can dump the speaker impedance to 2 Ohms, and cause you to loose amplifier output.
