Onken for Fostex FE166En

ziocalepino · 17th October 2010, 06:36 PM

Hi people, any idea for plans to build Onken for Fostex FE166En? I've heard them sound and look great!
Thanks all,
Z.

You need FE167e (One Sixty Seven) for Onken style enclosure.

FE166En really wants a horn...

Hey Dave: remember I had pretty good results with a FE166e in my K-line (hybrid Karlson) so that is a possible option that is smaller than a horn. All the best Moray James..

Yes i remember that one -- i knew it was the subject as soon as i saw your name

... (someone said an HD crash ate your copy of the plans?). I also seem to recall you saying it did a bit better with FE167?

I've already built a horn for 166, Fostex' original, but after having heard Onken's one... well I'd like to try! As seen in few uncomplete picture on the net Onken seems similar to Solo-166 project. Isn't it? Anyway, has anybody Onkens plans?

Why? Driven with a high output impedance or adding some series resistance allows a F3 = Fs Onken without exceeding the vent length limit and you still have whatever 'sweetness' this driver may have over another.

Not such a bad idea if efficiency isn't an issue. I added 6 ohms of series R, but system eff. is down a little over 4dB. I also used n=5.7, just to make things easier.

Was looking for a few other options for my FE166ens besides the BIBs in which they are in. Googling brought me to this thread.

Did anybody end up building a Fonken with the FE166en?

Any feedback suggestions will be appreciated.

Thx, Zia

I just simmed one. F3 ~110Hz, F10 ~86 Hz.

Might as well put it into a butterworth 5.3 litre sealed box and XO to a woofer (150 Hz XO (3rd order acoustic)).
