Neither of those is well suited to a true horn, For the FE207 you would likely be better off -- and have a much simplier build -- if you used one of the modern designs specifically made for it (ie any of the appropriate Changs), The SEAS are sufficently expensive that it will be a while before plans start trickling out, and the AN, being David Dick's house brand, also don't get as much attention as the Fostex. Some of those would be better served with horn loading than the BR David Dick's recommends.

Just to point out, those are not coax drivers. They're FR / WR drivers. A coax generally implies a multiway with a tweeter firing through the centre of the larger bass cone.

I imagine Dave was simply curious about what drivers (specifically)the cabinet was originally intended for -there are very few such units he hasn't seen, & you won't find many people with the kind of experience he has with FR drivers generally.

Just to echo what he said, neither the FE207E, nor the Seas unit are especially well suited to horn loading -too high a Q / not enough raw motor power to be ideal. You would be better off with Fostex's FE206E, FE208ESigma, FF225K, or one of the cast frame Audio Nirvana units, which as Dave points out, are inherently better suited to back-horns than BR or sealed enclosures.

You have really lucked out Mark by finding this site when you did. Since enclosures are usually designed around a particular driver and not the other way around, it would be best for you to find an enclosure style like the Mellow Monster to build and use the driver it was designed for. I'm not trying to Boo Hoo your plans, I think you will find a more suitable design here.

Also, most if not all of the enclosures on this site have been designed and then tested and then modified as necessary. Some plans, even from the driver manufacturers, are OK but not evolved and corrected like the designs you'll find here. It may take a lifetime for you to notice or appreciate the differences but why not build a superior design to begin with?

I've been looking around a bit and the MellowMonster is a bit different concept than most of the horn-type enclosures I've found, with 'sideways' folding. Pretty interesting, and it might be a good point of departure for something worked over with modern software.

The MellowMonster does have the advantage of not being 5 or 6 feet tall, or being the 'most interesting' looking thing in the room, so might appeal to some folks on that basis.

Can you suggest some other compact horn designs I should be looking at for larger drivers like the 8"+ AudioNirvana speakers?

Thanks
John

Very good points. I'm sure the UberFanatics here are already adjusting some of its dimensions to better suit the current stable of their favorite drivers. I have yet to see any FR designs utilizing an 8" driver.
The Fonkens are rather cubic like and perform at the top of the class and ironically they seem to have the simplest internal mo-jo as well.
I wonder if the 8" has the ability to produce the HF without tweeter help.

I don't know about the AN 8", but I have AN10s and to my ears (and more importantly to a friend's who has some very nice audio equipment and whose ears are younger and better than mine) they do just fine reproducing the HF end of things.
Cheers

The cabinet in question is just a somewhat modified (& inferior, IMHO) version of one of Olson's Studio Horn designs from the 1940s. YMMV of course. The latter were the inspiration for some of my enclosures on the FH site.

I understand where you are coming from Mark, you've wanted to build a Mello Monster for years and it has been gnawing at you.

Since these will be more than just a couple of new end tables, how they perform is equally important I am assuming. It was an early design and I read on one of the pages.."But we don't mean to imply that it is theoretically correct". As mentioned above, some of the enclosures here are evolved variations of the MM concept that have corrected or improved apon its faults/weaknesses. It looks as complicated internally as most I've seen and not nearly as interesting or beautiful on the outside.

Scott-
I seem to have some problems navigating around the frugelhorn site- which of your designs are you referring to?
Thanks
John
