Excellent build! The 10 seems to have the smoothest response of the Alpairs, how do you find it? Is the treble as extended as the plot suggests? Looks like quite a special driver

Your woodwoork is lovely. We have the same issue facing us with the bass on the MJK horn for the A10. The primeSize miniOnken for the A10 has good bass.

Awww, you say the nicest things.....

it was a straight winisd thing....BR is not really my thing but I needed some nearfields for the studio........the predecessors were mackie 824s and tannoy reveals so they've got their work cut out if they want to avoid the skip(dumpster)......

its 10ltrs with 47x177 port and with the port open they are frightening(bad). With the port stuffed they are the equal of their predecessors(so far) but I will start measuring in earnest tomorrow.

10 litres is a bit small... i settled on 13 litre (and then my hiR ports -- if i use a piece of PVC pipe i inevitibly end up putting a "sock" in the port. Sounds like soe judicial use of carefully cut open cel foam is required.

Dave,

Where would I look for some of that blue foam packing material?

I get it from the Apple Service boxes that i am reponsible for recycling. I usually use the waffle stuff for packing. There is some denser stuff in the same boxes that makes for good aperiodic port material.

That's odd, as the fr plot in WinISD looks pretty good for that tuning.

Ok, I should have been clearer. How can I obtain some for myself? In other words do you know where I can buy some?

Thanks...

Try a packing company. Or go to you local Apple service and ask if you can get, and recycle any spare service parts boxes.

Box is a tad small but try stuffing the ports with drinking straws cut to the same length of the port, This should add a bit more resistance and still keep the tuning. I've found little changes with the upper bass in this fix yet the lower registers seem to be much more controlled....
