Fostex FE208E Sigma

bbr81 · 21st February 2011, 08:53 PM

I have recently purchased a pair of FE208E Sigmas and I am looking for a smaller cabinet design than the recommended version from Fostex.

I came across the below website and found this one but do not have any dimensions. Has anyone ever seen this and can direct me to dimensions or know of a good smaller design?

???? FOSTEX 208??(????) Yahoo! ????

Thanks

The smallest box that will get decent performance out of the 208eS is likely the RonHorn Dallas II

Why would you buy a large driver that is obviously meant for use in a back loaded horn cabinet and then try to find a small cabinet for it? Any enclosure that will make use of its strengths will be huge, especially by UK standards.

Hi bbr81,

You could do an MLTL (mass-loaded transmission line) but my wild, unscientific guess is that the cabinet would be about the same size or larger assuming you want as much bass as possible.

Interesting that no tweeter is apparent.

It's a great driver. I'd put it into a pair of BIBs and stick them into the corners. But that back horn in the link is very cute indeed. I think it's worth seeking out the smallest back horn. At least you will get that horn sound but without the greatest bass extension. Smaller backhorns like in the link probably go down to 70hz or so and can be supplemented by a powered sub.

Not sure if this is smaller at all, but it's kicked up a notch although more $$$ to build..

How big would a BIB have to be for this particular driver??

Love those BIBs... also love the poster of the fish down the center of the room.

Here's a link to the BIB calculator.
