Hey, I'm hoping to find plans for Ghorn and Othorn, can't seem to find them anywhere. Thanks in advance  ^_^

 

Files posted. I've been meaning to do that for a long time.

Hey Ricci, do you do any builds of these for other people, or offer flat packs of any sort? I'm not too far away in Nashville, could easily come to you.

Hhahahahaha! Sorry I'm not laughing at you at all. It's just that I can't even get time to build my own cabs anymore. I pay someone else to do it.

That said there are people out there who can do this type of work and will for the right amount of money.

Anyway welcome to the forum. :)

Just out of interest (who knows what the future brings), how many man hours did you have to pay for the horns you had build? With these plans on a first build.

It was never billed out in man hours to me for any of the cabs I've had built. We just negotiated a labor price on top of the raw materials costs up front. I never searched for someone to build any of my cabs either. It just kind of happened that I know some fellow DIYers who were willing to work on them for reasonable prices.

I had the Othorns, Gjallarhorns built by one guy. The MAUL's by someone else and the Skhorn's most lately by member DSL1. I covered materials+ shipping+enough extra to cover some labor each time, but I probably got quite the hookup on some of the labor charges. In fact I know that I did.  Just the wood, duratex, glue, wire, screws, handles and shipping on a pair of any of these is substantial. The labor hours are also substantial. You can save a LOT of money by doing it yourself but be prepared to put the hours in. If you would rather have a pro or someone with a full on cabinet shop and all the tools build them, it will cost. 

If you need to discuss in more detail we should take it to PM.

And then whatever number you come up with for dollars or hours, double or triple it. :)

These designs seem to be different than what was tested on the measurement / analysis - bench-marking page. Can anyone help me locate performance specs of Ricci's designs?

Both appear to be fantastic, but I want to building these (with 21" b&c's) as low end support for bass shows at a venue with all ready existing 15" drivers... which makes it seem like the g-horn might fit the need of the space better given the existing system. 

 

Thanks guys, 

Andy

 

EDIT: it appears the data is for the version 1 ?

Yes data is for version 1. I never built and tested v2. It should offer some minor improvements but they are incremental not game changing. Acoustic performance differences should be relatively minor. I'd suggest the Othorn or Skhorn for live sound or reinforcement.

I'm feeling abit confused right now about the Othorn plan, cos I was told I probably have an older version of the plan. Is there a V2 plan?

A few days ago I ordered two 21SW152-4 so I would like the latest version of the Othorn plan.

If anyone is interested to see some building pics I gladly share. The two finished Othorns will be powered each by a bridged Crown I-Tech 6000

The file attached here is the most up to date. V2 has doubled bracing as shown in the attached print. The original had less internal bracing.

Thanks Ricci, in the end of this week me and a friend, who owns a cnc, will have a look at the plan. We will decide where to put handles and casters.

I was reading that the bottom part of the Othorn, where the hatch panel is, is one of the Othorns weak spot. I was thinking to "solve" this to put a dolly at the bottom of the box. But would this effekt the sound in a bad way letting Othorn stand on the blue wheels while playing?

Can't wait to fire those up 😃

That should be fine. The mouth or driver acc3ss hatch is always the weakest spot with most traditional tapped horn folds. Usually they can sit on that panel in use.

When you say driver access hatch, do you mean where the driver is mounted?  Would it help to place a 2-3 milimeter thick metalring to be a part of the access hatch, having the cutout size of the driver and screw them together?

I do not think that would help. Just make sure to brace the hatch. Or just sit the cabs vertically with the hatch on the ground.
