Hello All,

I have a pair of BeoLab 1 speakers and the top and bottom bass isnt playing anymore.

How do i find out which parts to replace...?

The service manual says its probably the bass speakers both it could also be the NTC transistor or the cooling profile.

When i put my ohm-meter to the speakers it says 0. When i measure the speaker cable going to the top speaker it measure 4 ohm.

Help!
