[santitrucco]

Hi friends , someone know which is the frequency response for one Fostex Fe206En in open baffle about 35cm x 80cm ?

Hi. This is a good place to start...... Electro-acoustic models

 

[santitrucco]

Thanks Scottjoplin , but i can not know which is the low freq resp in an open baffle with the info of the web..
Fostex 206en have only 1.5mm xmax.. and i dont know how to calculate the FRQ Response..

FE206En on an OB will have less bass than on an IB, and that is near none. Add a big *** woofer and biampif you want bass.

Which means, at least two efficient 15" woofers or at lest one 18" one. Ideally, two 18" woofers in H-frames. And no, I am not kidding. That appliws if you go passive.
If biamped and actice , you could probably do with one 15" but that would stress it if you want to play it louder..
I know, I tried my Fostex Fe206 e in OB and didn't like it. Forget about any bass out of it, the XO was around 400 hz, but I didn't like its sonic presentation, so I went back to Visaton B200...
P.s that is, with 15" woofer, biamped...

OK , and if i use the Fostex double bass reflex enclosure , with the 206en and then the sub only for 60 or 70 hz and down ?
Now i only have one Koda 12 inch active sub..

 

[santitrucco]

Of course , i could do new enclosures

Good luck getting any usable SPL from unassisted 206s in the neighbourhood 60-70 Hz in anything less than appropriately designed BLH / BVR. I doubt all the EQ and power you might muster could overcome the excursion limit you’ll otherwise encounter.

The factory DBR is not all that good. For FR use the FE206 wants to be in a horn.

If i use a good designed Back loaded horn + one sub ? would be fine ?

 

[planet10]

The lower you want to go, the bigger the horn is going to be. Dallas II, Kirishima, or Vulcan will all get you there. With the last… depending on your room… you may find the sub optional.

[santitrucco]

and what freq bass could have one big back loaded horn like Dallas II, Kirishima, or Vulcan ?

 

[freddi]

206 work well in a Karlson K12 ~24.5"H x 16.75"W x 13.75"D (I might not use the distributed slit vent but rather a single vent )

and what freq bass could have one big back loaded horn like … or Vulcan ?

Woden Design | Vulcan

In room can be lower than specified.

Optimally loaded, Vulcan is a very easy 40Hz. That 50Hz was over-conservative of me.

retaining the classic projective Fostex character..

How very polite.
