There's a lot of good stuff on the FullRangeDrivers forum and more on DIYAudio Forums-Full Range. I lurk at those two and here at Audio Round Table.

I have played with the original AN6 drivers. I put them in my FT-1600 cabinets (MLTL's). They sounded terrible in comparison to the Fostex FE167E's. They lacked the detail and smoothness of the 167's and were overly bright to boot.

I just completed a pair of FB-20 cabinets (BR's) loaded with AN super 8's. They compared fairly well to the FE207E's I normally use. The difference here is probably more one of taste than good/bad. Even with a healthy application of BSC and a modified zobel, the AN8S's are a bit too bright for me. Perhaps if you are using a tube amp with rolled off highs, the AN8S might be a better choice. I still prefer the FE207E's. Well, actually, I prefer Lowther DX3's, but that's an entirely different league.

Basically, I think that the build quality of the Fostex drivers is better than the AN's, even though they both come from Chinese factories. I particularly question the refrigerator magnet material used in the AN's rather than real ceramic magnets. The AN's are heavier, but they need more material to get the same flux density as the Fostex.

Oh, well. It's your choice and the only way you can make an educated decision is to have both side by side.
