Hey Joseph,
Just send the first two samples to Vance along with a giant prototype horn, should be reviewed in a few months.
Hey Allen, not yet. The patent should grant by the end of next year, at which point we can discuss it.
That's me! I have this info in my profile page, but it doesn't appear there's anywhere more visible I can put it. Any suggestions?
The 8Ω version is approved and should go into production soon. You'll have to decide how you feel about sound quality, I don't think it's appropriate for me to make a subjective comparison.
I hope they know what to do with this. If they review a giant horn I would be disappointed, I already know what one sounds like.
Bennett would you like to elaborate a little on that horn ? Will it go into production one day ? Size ? Usable lower frequncy ? Directivity ?
Regards
Charles
Hey Charles,
Sure, a photo of it is attached. It loads to about 300Hz, but we have no intention of making exactly this horn commercially available. I sent one to Vance because otherwise there's no commercially available horn that will allow the full capabilities of the driver to be tested.
Whether we'll build something for general availability is a topic of heavy discussion, given the following points:
- None of our main OEM customers will use any publicly available horn we build.
- Any horn this large will be quite expensive to build, and especially to ship.
- Tooling costs for a horn this size are enormous, so we don't want to design and tool a family of horns.
- Hard to decide what a reasonable pattern and cutoff would be, which could be catch 80% of customer demand outside large OEMs (who will build their own no matter what we do).

Hi Bennett
Thanks for sharing that picture. It looks very cool. A pity that it will not be available. But I understand the reasoning behind not doing all the effort for something that might not sell. I do also understand the reasoning for building a one-off that helps showing the driver's full potential to testers.

That's where some of the secret sauce is. Every manufacturer has their own way to design a horn that meets their objectives. Also if an off the shelf horn and driver is used it makes the loudspeaker very easy to copy. I've got the first cut of an OEM horn for this driver designed, I'm just waiting for a pair for testing.
I'd guess the DIYers who are not prepared to roll their own horn are a very small percentage of B&Cs market, especially for drivers like this.
If a driver sounds bad when first put on a horn, doesn't mean it's a bad driver. Nor does sounding good on a horn mean it's the driver I want.
That was a project on another forum a few years ago (not mine).
They made a small number. The price would probably drop for larger batches.

For an OEM there are 2 main objectives in the following order, reduction of:
1. Cost
2. Size.
Size is 9 out of 10 times a performance limiting factor for large format drivers.
(also) A little reductive, but still: the best horn is an oversized horn.

I run the BMS 4592ND midrange driver in the Volti 260 wooden horn and it is as smooth sounding as butter crossed at 400hz.
Really hard to beat at the price! Its a big horn and agree with your statement.

That's what I thought too, but I don't have this option.
