yes the original K -- the only differences will be the internal wiring cabinet materials and drivers but the cabinet shape is exactly the same. Indeed, Peter would have preferred to have had the original drivers over the VIFA ones he's using with his AN-K's Rubber is an atrrocious conduit for sucking the life out of bass resolution and he could not get a driver maker to replicate the K's driver to his spec -- he would have to buy them in 10,000 unit alotments and the K isn;t quite a big enough seller.

The AN J gets considerably more bass than the original Snell Type J -- I have not heard the Snell J but the AN J sould remind the listener of and electrostatic openness in the midrange but not the narrow sweetspots of panels and it should have horn dynamics that presents a massive scale and power especially on horns with a front to back dimensionality that is rather spookey --- and at the same time be all day listenable even at louder levels. If the Snell J was not doing anything close to this then I would be surprised with all the raves Stereophile heaped on Snell and all the dealers carrying the line (These guys were huge in the 1980s). Indeed, Peter was a dealer so Snell stood out for some reason.

The one negative aspect however with all of these speakers using foam surrounds is that in humid provinces or states and countries the foam could need replacing every 5 years. In B.C. 20 years+ but in Ontario = 5 years and when the foam begins to go the sound is ****e.
