Oh, that sounds interesting. Who doesn't want a little color? I love a bit of personality with my speakers. Thanks GM.

I wonder if an Onken falls into the same territory as a Karlson (never had the pleasure of hearing either) by having its own distinctive personality (with its fans and detractors).

A bit of personality is fun IMO. Seemingly in the same vein as the titular speakers, the old Philips Monitor 8 for 9710 also appears Onken-ish to me, and I know from experience that the driver does have personality. In my Karlson 12", 9710 did well.

Karlson vs Onken: at least one of them seems to have some at large acceptance...

Hi all

very nice project ! Thanks for sharing !

although it's an unusual sized driver (for me), I wonder what is the thinkness of the plywood you used for the enclosure ?
Just as "fit by eye" it looks very thin to me.. ( or the driver is so large

)

And an estimate on the hight - something about 80 to 90cm to put the tweeter "on top" - is that right ?

Have fun with your nice speaker !
Thanks

The design calls for 18mm high quality ply (MDF is insufficient -- makes good vent spacers thou). Once the braces are in it should be sufficient... i'll tell you whether i'm happy once we have done ours... if it doesn't satisfy me, i'll add more braces before i increase panel thickness.

correction, those who've seen Dave's cabinetmaking handiwork will understand:

or, i'll add more braces to the drawings... i'm not allowed to make cabinets any more (i use too many screws -- ie 1+)

I hope you like 'em Dave. I'll look like a right twonk if you find 'em seriously lacking

On the other hand I like 'em loads

What over drivers would work with this box?
I may give it a try myself.

What are they like off axis? Much beaming?

It is tightly tuned for the 12LTA.
