Fancy a driver suited for a sealed box on sale?

Then there is just the right kind at meniscus audio, Eclipse W6520R-8 currently selling for $41.82. Got the TSP almost like the vintage Dynaudio 17W75.

Risky. If a manufacturing error resulted in wrong parts being used, there is no guarantee that distortion performance will be good.

It seems to me that either the top plate hole is too big or the pole piece is too small
so that the gap is wider than it should be and the field strength is low. The Fs is
correct so the motor strength is probably low and the sensitivity is also probably low.
Not good.

It could also be that the top plate is too tall, which would result in the magnetic field becoming "stretched out", for lack of a better term.

Take them for what they are: cheap, and potentially pretty good if the new T/S suit.
