The box is tiny, you need to put it on a desk or shelf. You could put on the floor for even some more bass gain but the sound will come like, well, from the floor 🙂
If you have some foam core, try it out as it is very easy and cheap to make. Listen to the polar dispersion and see what it is all about.
Sorry, but I don't think it sounds very nice. It has the hollow and peaky sound that results from standing waves, which are the hallmark of this design.
I really would tell you I liked it if I did, believe me.
The angle turns out to be 32 deg, but I just go by the fact that the baffle board goes up 4 in and inch and in 2.5 inches.
Hope you build it.
Fair enough - we are all entitled to our opinions. Lots of people think it sounds good though. I am not sure what you mean by hearing peakyness and standing waves?

thanks, fortunately most of angles is same at or nearly close to 60 degrees.
do u recommend horizontal as pictured earlier message or vertical brace for FE83?, great drawings by the way.
Hi Greg
this drawing was really more of a response / question for ChrisB, who as I understand it is the primary Maker behind Planet10 and, as such, can safely be anointed with holy water. My instinct is horizontal, on the basis of a greater impact by reducing the span of any un-braced walls... the horizontal brace cuts all four main walls in half -- whereas the vertical brace leaves the sides unbraced between the floor and the driver brace. But I am but an grasshopper egg, and eager to learn. Haven't gotten a response from master C.

u r very modest, hopefully CB will chime in, your experience with horizontal brace was very positive though...
hey XRK971 -- your clip has excellent bass - who is the singer? - it sounds fine to me but I've not heard the original cut.
Are you talking about this clip?

If so, that is Rebecca Pidgeon - "Spanish Harlem" in "The Raven" Album, Chesky Records
Very pretty clip, can you tell me the details? The bass is nice... but I get a lot of lower-midrange smear, like a resonance -- almost to the degree of an echo. Room effect? Is that a Karlsonator with an FE83?
No, that is an XKi with a Dayton RS100P-4. The impulse response is clean, the echo is in the recording itself - probably recorded in a mildly echoing hall.

it sounded good on my rather run of the mill surround headphones -in general are a no-no for listening to recordings of speakers as they add a "room" besides their own problems- - hope the Beta 8cx XKi turns out that good.
is this the direct recording? - guess its the NS1000 - - X's speaker acquits itself quite well in comparison to the Yamaha and the direct track(at Amazon) https://www.youtube.com/watch?v=i5qAKZy_420&x-yt-cl=85114404&x-yt-ts=1422579428#t=22

hi mwhsmith,
driver placement dimensions are not included in this picture. is that not important?
do you get enough bass with this wine box?
thank you for providing all the info!
Hi Narmex
The Wine Box was good, but it's better with a little more internal volume. Here is a drawing of my 6th experimental box for the FE83! Also, the uFonken, with a 66mm wide port spacer, is quite good. I've found that any cabinet I've made without the driver brace suffers from a subtle "honking" tendency, and has less of a coherent presentation. The driver brace improves the sound significantly by reducing resonances, including a mid-low bass resonance around FS. Also, lining the interior of the cabinet to dampen reflected and standing waves is very important (I used a medium-density PolyFil felt from the guts of a retired, inexpensive sleeping bag).
Have a ball with this one!

An externally hosted image should be here but it was not working when we last tested it.

one should be able to cook up a little RJ vented reflex in foamboard or cardboard and duct tape - perhaps not try to truncate the cone area but instead run an Eliptoflex style opening like this Russian example below the picture
of my slimline R-J 12.

MWHSmith, that drawing you had of the improved box for the fe83s does not load, could you re-post it?
thank you mwhsmith for the reply!
any words on driver placement on the wine box?
i tried to open the attached pic, it didn't show.
i'm a noobi, please don't laugh at me. is a driver brace to be set tightly against the driver magnet?
what software(s) are you using on the FE83?
i did a cardboard box mock up of the winebox.
i may be wrong, but i got a feeling that the FE83's highs are projected up front too much, near field listening drives me crazy. some distance away it's much better, maybe the highs roll off some, and get more balanced with the mids and lows.
i tried a few other boxes for it, none worked, the overly pronounced highs are too annoying with this driver. and i didn't get much lows either. in the worst case, the sound became rather muddled, not clear at all. maybe i need to give it some time to break-in?
or it may just be i don't know what i'm doing. please keep the forum updated about your work. thank you for sharing all that!
