FE206En based BLH speakers

[jackgreen]

I have currently FE166En back loaded horns at home:



I'm planning to build FE206En based encosures, based on drawings at Fostex site. Are thay good? Any personal experience?



Do You recommend to add also Fostex super tweeters? I see, that FE206's frequency response is pretty good at 10-20kHz region.

Yes, I have built them using 206En. It is pretty straightforward, if you follow the measurements as given in the Fostex design. You need to dampen with felt/glasswool for best responses...

Have You tried them also with Fostex Super Tweeters, as Fostex recommends?

[gopib]

No I did not add the tweeters. I was very happy without them. I listen to mainly Jazz and some classical...Since the imaging and reproduction is very good for me I did not feel the need to experiment further...

The Fostex horn is designed for ease of build more than for getting the most performance out of the driver. If you like your speakers, then you'll likely like the fostex box, but be aware that a few other box designs may be even better in the low frequencies, sometimes at the cost of ease of build. For example, Ron Clarke's Dallas 2 horn is said to be exceptional.
Between designs, if the horn length is similar, then a different design may give you a somewhat different quality of bass, but likely not a much different quantity.

I'd wait until Planet 10 releases the latest version of the Sachiko cabinets for the FE206En driver.

This was also my concern. Construction looks sturdy and easy to build, but this is far from "perfect exponential" horn, rather there is a series of opening parallel tubes.

I've found images of the enclosures with much better horn intersection, some without measures.

I have not long built a pair of Woden Designs Vulcans which I must say I'm very happy with, they took a while to break in but sound great now, though it wasn't till after I'd built tham I realised I had 206e's.

I thought i read somewhere that this cabinet was just ok, i would pm dave at planet10 or scott m. i can't find the thread, but read it recently... JP

I built a pair of the factory horns last summer, They are the best sounding speakers I have heard - indicating I may have limited exposure to good speakers

I have started a set of the Sachikos for my next project. From what I have read I may soon be the only person to have both for a side by side compare.

For my money the factory designs are not a waste of time.
