Hi Guys,
long time no see.
It is time to do something new.
I have two pairs of alpair 10.3m lie around.
I looked at all the recommended enclosures and think the FHxl would be fine.
but the footprint of these is to large. I would like something in my favourite
100 x 25 x30 cm.
I also would like to do some dual driver as I already have them on hand.
A larger micro tower would be fine or a double MarKen wich I have seen already, but I did not find any plans for both of them.
So I'd like to develop something by my own.
playing around with hornresp I came to following approach.
It's kind of transmission line loading into a horn.
What do you think?
Is this a way to go?
thanks in advance

There is no larger microTower (but it is certainly doable), most of the Mzr-Kens are in paid plansets.
For 2 drivers take a single driver enclosure and “double” it.

But it is almost 40% of the total SD of both speakers.
The Sd has nothing to do with it.
dave
If the opening to the horn is not dependant on sd. What else ?
Vas, Qt, how low the box is tuned, the volume of the box, the driver’s volume displacement will put a limit on how low or loud they can go.
There are no real easy answers, these really need to be modeled.

You are right chris.
But to see if there is something totall wrong it was sufficiant for me.
The log graph gives basically the same results.
Green line starting at 37hz.
The alpairs are wired in parallel.
Amplifier is a magnat tube rv2

So,
during long listening sessios I adjusted the damping. As always., less is more.
Everything glued together.
I oiled the birch ply with linseed oil.
The oil is in dark walnut colour. Looks quite good.
With the dual binding posts I can run the drivers in parallel or in series.
Binding post panel is sealed with self adhesive foam.
Last thing missing is the removable clothed front grill.
