Default Detailed plans for 206, 207 or Jordan

I am interested in building a pair of fullrange speaker and have for the last couple of weeks red a lot on this and and fullragedriver forum. Since this will be my first diy project I want to keep it quite simple. For driver I looked at either at the Fostex Fe 206, 207 or the Jordan JX92S. The thing I am having problems with is to find a detailed cutting chart like this: http://hometown.aol.de/hphinder/homepage/ The only detailed chart I found is for the 206, 207 Fostex recommended enclosures but from what I read these are not always preferred for the above mentioned drivers.

As far as sound I have a fairly large living room and would like some volume as well as the good bas response.

If anyone have any suggestions and link I would be very grateful.

Regards

John

Fostex publishes detailed enclosure plans for each of their drivers.
http://www.fostexinternational.com/d...ec_enc_1.shtml

Also, Martin King has provided a ML-TL plan on his website. IMHO, this would be the best design to go with in your situation.

For the Jordan there are some detailed plans on the Jordan website. For a horn variation, try zHorn which has a horn design for both the Jordan JX92 and some Fostex models (with comments on how they each sound).

Finally there's a neat TL design and set of plans at the Tidy TL site.

The TL design on the web page models, well, not so good. I would go with a design from GM or MLK.

I have ordered the Fe207E and will start with the Fostex recommended small bass reflex enclosure just to get a feel for the sound and the woodwork involved, if it sounds god I will go on building a the Double bass or some other "bigger" enclosure.

Thanks for the help

John

Default Warning - patience is required!

John - DO NOT give up after you turn them on for the first time, foaming at the mouth.
They MAY NOT sound good, depending on your other gear and the music you listen to.
They WILL take time to run in
I understand the bass in a bass reflex is a compromise, compared to horn/ML-TL type designs.

Default Fostex enclosures

nice to hear other people expermenting with the same speaker i am working on.

I enjoy listening to the fostex fe207 in a bassreflex enclosure at the moment.

They do sound a bit middy but are absolute very good speakers

Did some simulations on this speaker and because the max x is only about 1.5 mm I think the best thing will be a horn enclosure.

beside that I wil use active velocity control..... (transconductance amplifier)

please report about the original recommended enclosure..
