I have for sale a pair of k141 drivers. These are 600ohm and were taken from on vintage silver k141s. There's a myth that these are the same drivers that are used in the lp sextetts. Well, that is a myth. These are not the same drivers. Infact, they're not even the same size. They are quiet a bit smaller and doesn't fit into the housing. I bought these based on that myth. But They can however be modded to fit by simply using a sealant/glue to seal the space between the baffle and driver. The drivers are in very good condition and I now regret trashing the beat up set of k141s they came out of because they did sound pretty good. So these are good for k141 replacements or for modded projects.
