Best 3" Voigt pipe plans?

[Glowbug]

Hey all...just picked up a set of Logitech "computer" speakers for next to nothing, and they have these neat 3" full range drivers with aluminum phase plugs. Not bad for $5 each. My plan is to junk the plastic cabinets and build a set of "real" enclosures for them, add BSC if necessary...basically see if I can get some decent sound out of these If I can't, oh well, I haven't lost much.

What would you guys recommend? I'm kinda looking at the Fostex FE87 recommend backhorn as a starting point, but English unit plans would help a lot What about Voigt pipes? I've got space for just about anything but open baffles

Thanks in advance.

You can't divide by two and a half?

That's exactly what I'm looking for, but there are no dimensions given, and the link doesn't work to the plans

I thought these speakers were big, is there a dimension measurement?
is there a way to find out if the tangband W3-871S would work?

thanks

6x6x29in (external). It'd be easy enough to investigate an ML TQWT like these using similar dimensions for the aforementioned drivers.

Now I have another thread to subscribe to.

Here or elsewhere I fielded a question about the noogies and
and the tangbands. This seems to be a fit for the Voigt pipe
question but I have no idea on how to do the measures.

Made them but with 4 inch units.

What a guy (link to plastichead). He does glue-ups in his living room.

Ya gotta love it.

I tried some floor standing experiments with TB's using
PVC. After that I decided they belonged on the
desktop and so the Voigt/Noogi looks like a better
solution. It's better for the following reason: most
Voigts, while eclypsed by other designs for floor-standers,
are always described as 'forgiving' as far as a build goes.

At 30 inches or so and with the drive down a bit, it
puts the listening height pretty much in the zone for
desktop.

Not voight pipe but I used logitech 5300 speakers to make TB3 bipole by Salas. Really like them, small and easy to build. Search for TB3 in this forum.

Hi Glowbug. Have a look at my thread: www.diyaudio.com/forums/showthread.php?s=&threadid=89314

I don't know if they are the best, but they are much better than the original cases.

Have fun.

If somebody want I have the Limes Plans and the Suono Magazine article.....

i would like those plans...

if you could forward them to me some how, those plans would be an educating read.

the noogie is a is 1/3 scale abby, so think 2 feet tall. the driver is the ff85k, which to my knowledge is the greatest flux density to cone weight ratio driver fostex or anyone offers in the u.s. with a rising response in the upper range, it gives an effect of a super tweeter that makes 100hz. so above low bass, it can describe near infinite detail, it seems. I have had a blast playing with those drivers.

another thing to look at is the zigmahornet. plans on singledriver.com

Better plans here http://www.planet10-hifi.com/boxes-fostex.html

Zigmahornet is intended for 4"

oh right....

I forget. I tend to think of what most people call a 3 inch, a 2 inch, and a 4 inch a 3 inch. 4.5 goes to 4, and 6.5 goes to 6. 8 is just 8.

I just measure the actual cone.

sorry to not use the same language here.

3 inch, or rather 2 inch drivers probably dissappear the most out of any driver. especially in the nearfield.

You can download here the Limes article in the Souno magazine (Italy),

Voigt, please, Voigt. P.G.A.H. Voigt you know.

An F-81 variation would be interesting...

It's on the author's site now, though the drawing is a dead link. You can try emailing him, but with the last update being in 2002, one has to wonder if he's still around: http://xoomer.alice.it/0galavot/limes.html
