double Horn for FE167

[Spassgeneral]

I have got a pair of Fostex fe167, not fe167E!

would they match into chili as well? Or do I have to change the cabinet? I have almost finished my Olivias. Changs are very easy to build and look great.

TSPs:FE167

Impedance : 8 ohm
Minimum Frequency Response: 50Hz
Reproduction Frequency Response: fo - 22kHz

S.P.L. : 95dB/W (m)
Rated Input : 33W
Music Power : 65W

Fs : 50Hz
Re : 7.2 ohm
Qts : 0.33
Qms : 4.53
Qes : 0.36
Vas : 30.2 L
Xmax : 0.6mm (0.024 in)

The TSPs are not too different to these of the Fe167e, I think.
Is a double horn recommended, or woult a TQWT design a la Kings No2 or Metronome suite better?

thanks in advance

Should be fine.

[Spassgeneral]

thanks, Scott.
then chili will be my next project.

Which enclosure would be better:
chili or iris?
iris will be much harder to build, but I would if it is worth sonically.

[Scottmoose]

Blunt answer is that I don't know. I haven't built either of them. The newer boxes should be better than the older range, but there's only one way to find out for certain.

[Spassgeneral]

there are too many enclosures for the fe167.

double horns: Iris, chili
Martin King's Project2 (which was my first intention)
Demetri
Metronome

I am sure the results will be compleely different.
My fullrange experience is limited to fe168ez rec, Martin King No.5, and untuned olivias.
I liked the mid-bas and midrange of the fe168ez very much. Hf extension was too limited, deep bass below 45hz not existent. Tey were able to reproduce details I never heard, neither with my sennheiser headphones. the soundstage was so three dimensional, that every detail could be well defined.
Kings No.5 was totally different. They played with much authority. Bass was very! deep, but not so accurate. Don't get me wrong, the bass was very clean, but not as exact as of the 168s. Voices were knife-sharp defined, Hf with well extension. The olivias are very delicate. They build a very three dimensional sound stage. though they are not broken in fully.

I like the authority of kings No.5, the detailed mid bass and mids of the 168ez recs, the reproduction of voices of Kings No.5, the detached sound of olivia that let You forget, that there are actually speakers in front of You.

So what will be the right solution for my FE167?
one thing is for sure, that only a single driver solution is to be considered.

I know, these are three wishes at once.
nothing to be left desired.

thanks in advance for your opinions.

Hello,
do you know my solution
POSAUNE
a double horn,
and because 0,6 mm is not
enough for 0,5 Watt impuls,
take two, one invers.

So,
here they are.
The first pair of kimChi, I think.

The cutted curves look pretty good.





everything in the right angle



the inner corners sealed with much glue



damn, I cutted the angle at the wrong side
I glued the cutted piece and made the angle at the right side.



first run.
I lined left, back and bottom of the chamber with some velt.
They are not completely sealed so far. But they sound very promising. the mids and hights are incredible. sound is a bit thin at the lower end. Will be better, when the sides are glued. I did not, because I have to buy sand for the caves first.



What about bsc? I think thy have to be correctet only at the very lower end beneath 300 hz ? . May be bs is not so dramatic because the 'front horn' beams the lf?
any opinions?

thanks in advance.

[Scottmoose]

Oooh! Looking good there!

BSC? None needed. The radiation from both sides of the driver is focused so it's not an issue.

I'd give them a pair of terminal panels though, rather than running the wire out of the mouth. It doesn't do the looks any favours at all, & it interferes with the vent / horn / waveguide (bit of all three) action.
