Shouldn't be that big of an issue with ~285mm long vents. I'll play around with the box dims for a bit.

Cool!

Ok, so after a bit of futzing around we have a box. Internal vol. is ~20L + 1.5L for the vents, minus ~1.5L for the brace and driver motor (guessing here). Included is a crappy layout drawing.

Cool x2 and I'm sure a lot more.
Blimey, thanks Jeff - I only got it working at 25+ litres.
I could and just might make a cardboard mock up of this on saturday, time permitting.

Great. In the mean time, I'll do up a better drawing.

Hi all - so built a mock up of the 20ltr onken type thing, supplied by Jeff. (see attached images). and hooked it up to a daytona T100a and an iphone.
Bear in mind....it's cardboard + I have no testing equipment save a mulitmeter (is that usefull?)
There is promise here. Although the speakers are so new - and do sound a little " 1 dimensional" (run them in?)
Maybe I am too used to multi ways with their discreet fequencies.
Definitely some "shout" in theses, especially when listening to Joni Mitchell (shout scream wai!l).
good for ennio morricone.
great for the stranglers.
good for zappa.
Would be hoping for more bass response + "punch" with wood.

er...now what?

Togril.

Nice work. I'm sure the speaker would bloom with a stiff wood enclosure, lifting the lows and mids in relation to the highs. If the highs are still an issue there are simple ways to attenuate those. Aesthetically, those Onken style enclosures are tops. Love to hear one sometime.

Build another box of course. Run them in for a while using the cardboard boxes. Then decide if real wood boxes are in order.

BTW, nice work with the cardboard.

That is way kool. Probably almost as much work as a wood set. the damping needs to be considerably thicker.
