Hi Guys,
I just been sent some information about a new build project in Hobby Hi-Fi magazine published in Germany. I gather the article includes a full plan showing how to make this cabinet. Also, there's specs for the network and a full test set of results on this system.
I've made this thread in Full Range because its a DIY build project rather than stuff related to the newer drivers I'm currently doing. So I'll flag this project and leave it for the interest of the rest of the membership.
Maybe the forum's EU members can enlighten?
Here's the link the magazine site: HOBBY HiFi
Cheers
Mark.

the X-over is 2nd order at 300Hz. in addition a wealth of notches, impedance corection and the like to make the filter a nice beast
Berndt Timmermans is known for his exuberant filters, more than once he made a design where the filter outpriced the drivers.. but this filter is moderate (by his standards).

On 1st pass you'd think a bit higher could simplify things by tieing in BSC (based on a guess of the box width)

I have seen some that have more parts than some of my amplifiers.

A few links of previous discussions on the same subject, plus how else to make curvy boxes without flexi-ply :

Crossover discussion for AP5+10
It is not worth translating the article in English, IMHO. (I do have a copy.)
We can do better ourselves.
(I don't like all these complicated notch filters.)
Or have a look at the 2 Japanese solutions (including one from Linhof that we listened to in HK).
I am sure Mark will give you more details if you contact him.

for start is the dimension
206x380x319mm (wxhxd) Plans are of a rectangular monkey coffin, unlike the pictures.
XO has 22 parts!!
dave
yes, the designer usually goes a long way to achieve this.22parts?? is this for linearity perfection?
just to show that this has nothing to do with being German: Spectrum Audio has a kit with the Alpair5 and the CSS SDX7 that only has 4 componennts in the crossover
MACS 57 Bausatz im Angebot bei SpectrumAudio-Spezialvertrieb für Breitbandlautsprecher und mehr

At what cost?

A relief, I might have to pinch that as a starting point for a pssive XO on Tysen.

such a big sub behind

Hi Henry,
I already made a new thread for the MarkO as this design doesn't involve an Alpair 5:
http://www.diyaudio.com/forums/full-range/161828-alpair-10-marko-design-germany.html
It's going to be confusing to this thread if you post something not related to Alpair10 - Alpair 5 combo.
Cheers
Mark.

ALPAIR 10 BASS + ALPAIR 5 FINISHED!!
Hi mark,
its been long time since i bought the 10 and 5 at ur place. after playing the 5 with HENKJAN's TL, last weekend i decided to make use of the 10 bass + 5.
i followed ur recommendation, 14L vol for the 10, and about 1-1.5L for the 5 in sealed on top side. the port is square with W 204 H 30 L 254mm.
the dimension is W 240 x H 330 x D 315, the materials used was
15mm plywood (9layers -- although its not baltic birch) for all sides except the side walls which is 18mm MDF melamined.
the passive im using now is 1st order series with L 1.0mH and cap 30 + 3.9 uf with 2.2ohm resistor on the 5, with the 5 wired inverted.
its very detailed presentation, somewhat 3d, but abit rise and peak on vocals and extreme highs.
the bass is incredibly fast, can take explosives scene on movies very well, but cannot go deep and low enough.
any suggestion for the bass?
cheers
henry
