Gaumont Kalee GK 379

[Rajiv]

Hi,

I recently picked up a pair of Gaumont Kalee GK379 HF drivers.

These drivers are similar to the ALtec 288 but built using a copper top plate and a 20 slit radial phase plug, which seems to have been inspired by the Lansing 285 driver.The radial slit phasing plug is a close copy of the Lansing 285 of 1937/38.

The Gaumont 379 uses the half roll surround type diaphragm of all Lansing compression drivers preceding the Altec 288, which used a tangential surround.

I tested them out yesterday using them as HF drivers with my Altec 605. They sound very good. I will now have to get an adapter made to fit them on to my 400 Hz Le Cleach horns.

Thanks Rajiv for your advice and thanks to another dear friend for locating me a GK 379 pair. As suggested by you, I have enlarged the holes for positioning pins and could fit a 288 diaphragm. Sounds incredibly good. No fatigue and brilliant performance. Looks like not much information is available on these drivers and it is possible that very few GK 379 drivers came into India.
