FE206e Question

[toen]

Hi, i am a beginer in this field.
I like to build one speaker using FE206E.

a.
I like dry transient bass, no slow trambeling woofers.
Wich type is recomended for modern jazz?

1. Quarterwawe
2. BIB
3.Zigmahorn

b.
Is it possible to direct the sound from the mouth, example BIB,
using 45 angel opening (like a bended duct) . In order to focus sound energy to the listener?

a) There isn't a Zigmahornet for the 206 AFAIK. The BIB will kill the others in the LF -large cabinet volume has its advantages, if you have the space.

b) Not a good idea. The BIB is a corner horn (though a rear-wall works fine) & uses the room to complete the horn flare. Remove that, you've only got part of the horn & ripple will increase due to the 'mouth' (which is really only a terminus) being under-sized & the acoustic-impedance mismatch. Part of the beauty of the BIB is the very spacious, almost dipole-like sound it gives to the LF anyway.

You may want to look at these:

Hint: Use a descriptive question so we know your subject like FE 208 etc. etc.

Also on that page you can click on Rons Horns and see the DallasII horns that many regard highly...

The BIB would be my choice just for fun, but they'd be mighty tall.. LF from the BIB's are killer and I'm only using fe108's.... Dave

That might kill the effect of the upward firing mouth. However an angled mouth forward would work.

Exception, i would not want to live above a BIB, unless you want a foot massage.

Gee i exceeded my 30 min limit on an edit.

I am not a big fan of directing an exit wave directly to a 90 degree reflecting surface ,as in the upward firing BIB. Energies that are reflected re-enter the mouth and can cause a cancellation/re-enforcement of the exiting wave in a time /phase/energy alteration effect. This can cause a lumpy FR curve.

Something like these corner pieces (albeit sealed, not spaced out from the corners) might be an interesting way to help the expansion & reduce reflections back down the horn path.

Thanks´s for your answer. A lot of impressing knowledege out there.

The spawn family looks really nice.

I found a really nice picture from scottmouse in this forum, i think it was some variant from frugel, with rounded back. Really good looking, called Bruce or something.

I have another question regarding horns like the frugel.
a)The soundwave from the speaker must travel shorter way compered to the wave traveling inside the horn. Will this causing any strange effect due the sound hits the ear with some delays?

b) Is the frugeltype the best option if i want a dry fast transient bass with FE206?

Scott, that looks like an interesting idea! My BIBs are in a room with a low ceiling. Thanks for the suggestion.

True, and the best sounding bass-horn systems I've auditioned were ones that were designed to have complimentary 'ripple' to the room's to yield a ~flat in-room response.
