9rw,
the drivers are similar but both have been changed.
the esotar 330 had the suspension related amplitude depression moved lower in freq and deminished making it sound more linear and dynamic/less nasal. output went up and distortion down. the torque settings holding the face plate on were more correctly adjusted to the driver's needs in our speaker system. then a few years ago the drivers were made lead free and soon after we started taking them apart and changing the solder internally to the cardas trieutectic lead free we use in the crossover. comparing the sound of a millennium top end to the se and earlier is quite startling. the mme/mxe even more so.
the woofer, up until the se was the stock scanspeak 8545. in the millennium and later, the 8545-06. this is a driver that is made for merlin only. it uses a mueller latex compound to add mass to the cone which quiets the upper end resonances evident in the mids of se. latter versions of the 8546-06 were made lead free and shortly after that we started soldering them internally with the cardas lead free trieutectic we use in the tweeter and networks. the result is a more continuous and smooth transition to the woofer. this makes the speaker sound more coherent, like a one way.
crossover and cabinet tomorrow.
