Fostex: FE164 vs FE166en

robber222 · 3rd November 2010, 08:52 PM

I own a pair of Odeon Rigoletto speakers. The Rigoletto comes standard with modded FE164 drivers.... the mod is basically just the removal of the whizzers. I have also "Mod-Podged" the cones and added phase plugs fashioned out of small vacuum tubes. This might be too general of a question (without more info), but I am wondering if replacing the FE164 with the new FE166en would bring anything positive to the table. Does someone have any thoughts on the subject? Thanks for your help!

What range do the FE164 cover?

They are much closer relation to FE167 than FE166... 166 is more efficient and needs different box loading.

Hi robber222,

I have those same speakers! Speaking strictly as a newb, the biggest improvement was just disabling the tweeter and taking out the crossover, which it sounds like you've already done.

If you want to roll drivers, just be aware that the chamber volume needs to be carefully matched, and you'll be in "trial and error" territory unless you simulate the enclosure.
