Awesome and good luck!!!!!
A few things all of which are my personal opinion..
I have sat down in front of half million dollar rigs that don't come anywhere close to giving the emotional connection that this implementation provides..
regardless of driver cost from lowther to feastrex, I do not believe a single driver can play 20-20 or 20-30 or 20-40 etc well.. it's all trade offs, and with every horn application I have heard, it's IMO tonality and emotion... sure I may have one driver with no xover in the signal path and have bass and treble extension and great attack but all at the cost of tonality and emotion..
needless to say that i am hooked and this isn't a gimmick 😎
My Office audio system : Demetri ML-Voigt with Fostex FE207e.
Great low-freq reproduction for the size! I plan on adding a super tweeter to help the 207e.
Thanks you Dave (planet10) !

An externally hosted image should be here but it was not working when we last tested it.
I use the foam for some (little but better than nothing) absorbing. I've put it only on the front wall as I am too lazy to attach it to the left and right walls where it will be most helpful in the early reflections.
Here is my main system (at home) ... the acoustic threatment and everything else is "work in progress".
Here I have Fostex Fe206eN (modded by planet10) in 208eZ horns, TNT Flexy rack, Apple mac mini with an external transport and DAC, early reflection absorbers and lots of bass traps (currently on the floor instead of on the ceiling so are not really visible in the pic).
I like the sound pretty much!

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?
Thetubeguy1954 (Tom Scata)
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.

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...
Thetubeguy1954 (Tom Scata)
Try a packing company. Or go to you local Apple service and ask if you can get, and recycle any spare service parts boxes.
dave
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....
