I am looking for a fr set up + a cheap tweeter for my apartment at college next year. I was hoping to use a fe206/207 in a BIB + the dayton nd20 to cover the top end. I tried to search but couldn't really come up with too much. The apartment would be like 25 ft x 18 ft x 8 ft, or so im guessing. Any input or research as far as implementing a tweeter with a BIB or other type of FR box designs would be greatly appreciated.

At 92 dB that tweeter isn;t efficient enuff to keep up with the 206 or 207.
As well you would be better off with the limited dispersion of a horn.
Keeping the theme of cheap, this is one we've tried that works not bad

The Fostex FT17 is the usual suspect

Scroll down to see how i added a rear firing tweeter to my BIB. The Fostex tweeter would work great for this application. My BIBs are for sale to anyone that wants to pick them up from my house on Long Island, New York.

I was just looking at the ft17h in my madisound catalog, after seeing it in a another project on here. What would the x-over involve for everything?
Thanks for that link as well

So far people are following the Fostex recommened single cap for the most part. I am working on something a bit more complex.

I've been thinking about this also. The problem with the single cap approach is that you wind up with rather raged dispersion. A actual cross-over in the 6kHz range might be a better solution.
Hmmmmm.

My thots exactly -- well not quite, i was thinking 7-7.5k. Here is my 1st pass of the topolgy i want to try. Need to get a set of boxes together to actually explore it, will probably do curvy Changs. 1st order on the 207, 2nd on the FT17. Doesn't include Zobels or resonance traps which may be needed.

Dave,
Exactly!
A full-ranger like the FE207E is made to order for a series XO. The reason I'm thinking of XOing lower is to perserve dispersion, i.e., get off of the 8" as early as possible as still preserve the full-range sound. You may be right though. I'll be getting to this in a while -- I'd like to have it worked out prior the the LSAF in May.

- fe206/207 + dayton nd20 or similar?
