Yes all 4 bass units working!Yes try them all and if you get sound out of all 4 bass units then we can assume the bass units and amps are ok
And no sound out of the other unit only movementAlso when you do the test you should get no sound out of the other bass units although the cones will vibrate.
No the dealer configured them to aktivDid you convert the speakers internally, it need the crossovers resolvers to a different configuration
Does this mean it's a faulty bass card or just don't use the external speaker terminal links?Also when you do the test you should get no sound out of the other bass units although the cones will vibrate.
Sound is normalgood we are getting somewhere. It looks like the Aktiv mod has been done or you would get sound out of both bass units at the same time. I presume the sound is normal, not quiet or distorted etc?
I'd removed the lower bass driver and remove the crossover to check if I were you. The aktiv conversion is clearly labelled on the crossover connectionsThe dealer said that they were configured Aktiv
It looks like a faulty aktiv card. The LK85 is more than capable of driving both bass drivers at the same time. You could try reconnecting the card in them making sure the connector is the right way around. It should only go in one way....
Thanks I've had the card in and out and apart from a brief spell of hum and crackling no bass. So I should get another bass card and not use the external terminal connecters then?It looks like a faulty aktiv card. The LK85 is more than capable of driving both bass drivers at the same time.

Are the Ninka cards just the same? Or could they be better as often might be newer?Yes. Definitely looks like the card or cable is either the wrong one or is faulty. You can leave the links on the speakers for now rather than complicate things
If you're running passive you must take out the link between the bottom two speaker connections, the bottom ones are for active only.
