Default Spawn Olson/Nagaoka Horns the Next Generation

No not yet, but really close...

Thr 3 optimized horns for the Fostex FE126En, FE166En, and FE206En have been approved as drawn. I have a bit more tidying to do before official release.

They could have been called Saburo v2, Hiro v2, and Sachiko v2, but that is a bit boring. They will be known as Kongō, Haruna, and Kirishima.

Here is a preview of Kongō. As can be seen differences from what preceeded are only in the details.

Not to be greedy but are there any plans for a half-Kirishima?

I'm afraid not. You can't just saw one of these boxes in half; it would require a new design. Since there are already several designs for the 206 with a single terminus, I've no plans to do one at the moment.

Never mind smaller, how about bigger? Am I right in thinking that horns, broadly speaking sound better the bigger they get? Hence the Kleinhorns and such. How about a design that used the length of sheet material as a limiting factor, so 8ft/2440mm.

Awesome!! Are there any plans for double mouth front exit horns for the bigger MA drivers? I thought I remember there being one for the A12 before but I could be mistaken.

Broadly speaking, yes - up to a point, but don't ever forget the room as the biggest variable in the equation. Just cause you could shoehorn something as large as a pair of Kleinhorns in a space doesn't mean everyone would appreciate how they'd sound.

I heard this system at VSAC2008 Click the image to open in full size. .



in a very long executive suite, playing vintage Jimi at "realistic" ( very loud ) levels, on an evening when there happened to be a thunder and lightning storm going on - obviously very memorable. These were one of the hits of the show, but simply too over the top for me - maybe this perspective gives a clue as to the potential WAF

If you count, you'll see 4 front loaded horns, and a big-a$$ sub woofer

clearly these boys, or Nelson, laughed at the constraints of 4x8' materials or real world domestic considerations

Scott

yes, there were, but the revision to drivers required redesign of enclosures, and Scott got busy with other things

Sort of. Depends what is meant by 'better.' When it comes to horns, more is more: for a given tuning frequency, the larger the cabinet, the less compromised the horn expansion is likely to be, assuming it's well designed and efficiently uses the internal space available. However they're also general DIY designs, so they need to have at least a chance of domestic acceptability for a reasonable number of people, and they're already at the top-end of that in size-terms.

Thanks. We did some initial designs, and a couple were prototyped, but a lot more work would need to be done, partly to refine the boxes, and partly because all the drivers have changed. Maybe in the second half of this year. Possibly.

Crazy as it sounds, I think it's called life outside of audio?
