Alpair-10 with Alpair 5, German combo

markaudio · 06:31 AM

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.

Sure be nice if they had an English eEdition.... frm the copies i've seen at Bob's they sure seem to go overboard with the filters.

Any idea where they are putting the XO?

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 :

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.
