This design looks promessing...

Found this on the net. Looks promessing to me.
Years earlier, i had this idea of combining a front and back horns
(for P.A.) similar to what a Altec VOT and Jbl 4530 Frankenspeaked together
would look like.
Building a similar design enclosure with a Fostex Fe208 seems like
a good idea?.
I could not find who created those wonders, would have love to
know more about them.
Would that front horn increase high frequencies too?.

Interesting. I wonder what it would do to the driver being loaded on the front and rear. I don't know enough about the specifics to comment further but the design idea is certainly appealing.

yes its a cool idea- have a look at the Tannoy Westminster.

I had an idea for an single driver omni in a curved cabinet - a 300 hz flare fires upwards into a reflector and the back loaded horn exits below tuned to around 40 hz

That idea is better implemented as corner loaded horns, "á la Autograph"
The front horn increases mostly midrange. The back horn's mouth seem not too big for a floorstander...but I'm only guessing.

Good luck if you jump in,

Yeah! it does have a Westminster influence.
I wonder if the high frequencies would be "buried" under mids and
lows...

The Beauhorn Virtuoso also has that midrange horn "thang" goin on.

I suppose the advantage a two way like the Tannoy Westminster has, is the tuneability of both the crossover and the cabinet in the design stage.

I suppose you know that the Westminster is the heir of the Autograph about which I was talking before...it has the advantage of being corner loaded for the bass horn. You need good corners, though...

Huge improvement - the TV is rendered useless (like it had a use anyway...).

The horns are close to each other because the picture is taken at the day they are being installed. Now they are close to the corners of the room. More pictures at bgaudio.org

Good corners let alone good rooms are rare in my present domain...that old adage, High Efficency, Small Size, Good Bass, pick any two ...seems to rear its ugly head.

For those who have done their own research...is there any less complicated construction that has a high degree or return of the "physical reproduction" of the musical event...or is it still true that the last 20% takes 80% of the resources...
