Default article in german magazine

I have learned that there has been an article in a german DYI magazine (Kang & TON or hobby HIFI) about construction tips for wall hanging speakers.

Does anyone know about this article ? And maybe have a link or copy ?

Hobby HiFi, issue 4 , 2005.

Three types of wall speakers were presented:

- small fullranger in case made out of Ikea bamboo plate.
- Manger Sidekick
- Flat TML using a Tang-Band driver

Regards

Charles

For a lot of the "Hobby Hifi" and "Klang+Ton" projects
you´ll find the plans somewhere on the net.
The Tangband TML from that issue nr.4 is here for example:
http://wt.parsimony.net/cgi-bin/view...ragsnummer=149

Here´s one wall-speaker from Visaton:

Would anyone be prepared to get me a copy and send to me, of the Issue 4 2005 as I'm interested in the Ikea bamboo plate project. Thanks. I can pay by PayPal.

As I understand the bamboo can be realized with 6 different speakers but I´m not quite sure if all 6 are complete projects with different filters.
If you want the Vifa10BGS version here´s all you need to know:
http://img58.imageshack.us/my.php?image=bamboo14fr.jpg
http://wt.parsimony.net/cgi-bin/view...ragsnummer=164

Now you just have to find out how the given parts are used in the notch filters.
High-pass-filter is given on the page with the frequency responses.

Seriously I might get somebody to scan the rest for me as well.
Otherwise I could try to get a copy sent.

greets
PS.: The main dude from Hobby Hifi BTW is quite famous for doing overkill crossovers so that the response is beaten up to +-1dB variation no matter how many parts it costs. You could probably go with just the high-pass looking at the frequency response of the Vifa.

Thanks for the information. My main desire is to find the plate in Ikea as I have several speakers that could be used. The second link says the Ikea article number is 300.251.36 but I can't use this on Ikea's UK search system. Is it the 45cm dish Hultet?

I can´t either but it´s gotta be the 45cm version.
Estimations would make you think that and according to this thread from a german forum the "lid" for the bowl is made of 430mm diameter MDF-circle.

The other five recommended FR speakers are:
Fostex Fe 87E, Veravox 3, Visaton FR12, Visaton BG13, Visaton FR13
There are no SPL measurements for these drivers, only bass simulations (aj-horn) and HP component value recommendations from these simulations for all drivers. The author states that the bamboo filter network should work quite well for the fostex and veravox drivers too.

I dare to enclose a picture of one of the most elaborated filter networks I have seen so far (for just ONE driver!).
