Default I think I want to build a set of horns...

Hey, I've been enthralled with horns since I heard a pair as a kid back in the 80s.

I'd really like to build a pair and I'm considering going with a pair of the Fostex FE166En and using the fostex suggested plans. I've built some subwoofer enclosures in the past, but I've never attempted anything on this scale.

I've been told that the Fostex plans aren't very good and that the Frugel-Horn 3 is better. I've also been told that the Lotus design would be better. I was also told that the 6.5 inch full driver may sound like a good idea but in reality I'd be better off with a smaller driver.

The more I read, the more overwhelmed I become. That's why I say I think I want to build a set of horns.

The room these will live in is 11' w x 19' deep. The wall that the speakers will be close to only has one corner on the right, the left side has an entrance opening...so corner horns are out.

I'm still a beginner and I'm trying to learn as I go here.

Any thoughts, comments, or suggestions are greatly appreciated.

There's a time-honored tradition of starting off with a simple ported box. It won't be your last speaker, but it gets you further down the road. And given your choice of driver, maybe check out these two articles:

I'm hungry for a burger...maybe I should eat a ham sandwich first though.
I know you're trying to be helpful, and I do appreciate the links and information, however I really do want to build some horns.

Been there done that. I've built a pair of A25 replicas, a small sound bar format L/R/C setup, and countless subwoofer enclosures (ported, sealed, bandpass, etc).

Agreed, but it's also not my first, but it will by my first horn.

h2oTom,

The FH3 is good. If you want more oomph and want to play louder, then take a look at the Frugal Horn XL.

If you are talking about the Lotus designed by Scottmoose - then that is a BVR (Big Vented Reflex).

The Fostex recommended horns are not among the best.

This driver may work in the Frugel-Horn XL with suitable damping changes -- the guy that installed the FE168eS (which requires similar loading) is happy with them.

Austin A166, Haruna, and Victor are well proven for FE166.

Smaller drivers are better in some ways, larger in other ways.

What kind of amplifier do you have -- it should be noted that these drivers tend to work better with amplifiers that have higher output impedance.

With designs like FH3 or FH-XL there are other drivers out there that can give a "horny" experience.

For Fe166EN Victor would work?

But that's a big one and does it need corners?

IMHO it is better to determine listening goals first, then choose a suitable design (taking into consideration room etc), and then going for the drivers.

Alright, you have the horn fixation. Nothing wrong with that, so just build the ultimate, the Austin. If that's too much work, a BiB.

Victor was designed specifically for FE166. They certainly needed no corners when i had them in my room.
