Not a tiny enclosure, and like the previous 3 members of the FH family - to which I’ve had some exposure - I’d opine they’d work best with a healthy amount of breathing space behind and to the sides of the rear mouth. Of course mileage and opinions will vary in that regard.

Nice. Do you have FR and distortion measurements?

I have experience with Fostex 203En-S, Lowther PM6A and Seas Exotic and like the open, microdynamic and coherent sound. I dont like the wizzercone recconance/distortion around 4000 Hz.

Do you think Alpair 12P is better here?
 
FR and distortion are in essence innate to the drive unit, except in the LF. Since the Frugels are boundary-loaded / corner horn designs, the specific loads vary somewhat with the room acoustic & the precise enclosure positions. That's why we don't provide anechoic measurements of boundary-loaded horns: they'd be more or less meaningless since the entire final part of the horn expansion is missing.
 
Hello guys, recently I have purchased diy cabinets with Alpair 12P. These are Pensils, the small ones but with extra bracings. Such a great drivers, so many details, however the quality of the cabinets is just so so... so I am wondering about making some new cabs :) it's been 8 years - if I'm not mistaken - since the drivers were manufactured... maybe there is something more interesting than Pensils these days? :)
