These and particularly Bernie's locust and VG Fir enclosures for the 12s and FF85WKs demonstrate the inadequacies of photos to do justice to the sensuality of this enclosure shape.

As much as they're a bit more complicated build than rectangular versions, I dare say the "T's are still a much simpler build than the Octagons - what's next, a dodecahedron?

$hit, now someone's gonna ask for drawings for that

you're welcome Dave,

Count me out, had a tough enough time putting together the standard Kens . The reward though is in the listening that follows later.

Maybe not next, but plans in place for a 2.1 dodecahedron system, i have the 4" woofers, just need to collect the required number of Foster 35mm drivers for the sats (ie what use is an old eMac?)

Maybe not dodecahedrons (yes, I DO know what one is!), but a cylinder would be great. That would fit right up to the face of a sphere and the slots would be concentric. Can't you just see it now?

Oh the dode's been done before -wasn't there one by Design Acoustics or some such - as well as



It just struck me as a perhaps needlessly complicated design from a fabrication point of view

Hi Dave. Sent an email to planet10. Slightly off topic but did not want to start a new thread.

Anyway need a new project and was thinking of the 22 litre bipole. Can't see those drivers still for sale on your site. Do you have suggestions for other drivers for that design. Have you tried some small woofers mounted in that cabinet for augmentation at all. Just a thought. It may already have some nice tight bass.

Not against a bookshelf style project either with say a 10 inch alpair. I'm in Aus so i have not heard any of these speakers. I'm also new to making speakers but have enjoyed my attempts so far. The other project i need to get up is a pair of woofers.

Anyone have some favourite designs they think i should pursue. Into vocals, R&B etc.

Posting because i'm not up to speed with all thie knowledge floating around on this site so trying to do that and have a project at the same time.

Cheers Craig

The 22 litre sealed would have been the sealed one for the CSS FR125/WR125. With hindsite i would recommend a smaller enclosure. 14 litres would be fine. Personally i;d go a bit smaller and make them aperiodic.

Bob is currently cleaning out the last of the WR125 16 ohms at 1/2 price. Add a pair of the ERT26 tweeters and XO with a single cap.

If you go ahead i would change the aspect ratio such that the box is wider than it is deep. This helps reduce the on-axis bipole dip.

Dave,
Is that still one of your favourite designs or do you have something else to suggest. What is the difference in the two css drivers.
Any comments re a woofer setup.
Those Alpair 12's you have for sale, what would be the approx post to Aus ,any idea?

[planet10]

We have built a lot of better speakers since those were done. The WR is extended range and likes help above 10k. The FR does not need a tweeter. WR has a bit more bass potential.

In the bipole-bipole we had FR one side and WR + super-Tweeter on the other.

If you wanted something in the same vein, i'd suggest looking at the microTower or Coniston^2, you can get the EL70 from Darcher in Tasi.

The Mar-Ken12s would have life-threatening postage. Given that max weight by post to Oz is 20 kilo you'd be looking at 2 15+ kilo packages at at least $160 each (actually i'm surprised it is that cheap) for slow boat.

Thanks.
Was just reading about the mar-ken12's. They sound nice to me. How would you compare that style of box with either the 10 0r 12 alpair? ie difference in the two drivers. Are the 10's a bit quicker etc. Alpair in general good with trebble ?
Cheers
