Now I've seen it all. To get the amp out you need to remove a speaker to
release the speaker wires internally. But its a dummy speaker, presumably
the 2 in the model name means 2 speakers. Basket , suspension , kevlar
looking skirt, and cone , only. No pig tails or holes for pigtails or Voice
coil or magnet. So if these were off a production line, how were they
further processed? 4x3 sets of holes in the basket for what I would have
thought were screw holes for a magnet , but sealed off by the seated cone.
Would they glue in VC to the cone and magnet glued in to the basket with
some sort of active monitoring of sound output , while posistioning in the
uncured glue?
Problem is the otherwise Ashdown Bass amp common symptom of loss of output ,
returning a few minutes later, but this one will then continue for an hour
or more with no drop-out. Not had a chance to power up yet , to investigate

Normal passive has no coil, but it might be there to damp, mostly over and
under resonance. Most effective below resonance, so the cabinet does not
cause overextension below driver resonance.
