speakers on a grand scale

These must be the perfect match for those tiny contest amplifiers:

Wow! That IS a bit overkill for a home scenario. Usually I have seen theatres with large horns like this. The problem with this set up though is that horns need a BIG room. I been working with theatre sound and horns before and you DO need to get some distance out in front of the horn to hear it properly.

I had a small night club contact me in regards to a bass problem they had. They were using 'W' folded horns for their bass and they had a pretty small 40 x 40 dance space. You FELT the bass, but didn't hear it too well. Yet, the bass in the lobby AND even outside the club was overwhelming.

I noticed this effect when setting up theatre sound systems in which standing right in front of the horn, you don't hear much in terms of bass, but you FEEL the pressure. But then get about 20 feet or so back from the horn and you are blown away by the bass.

It has to do with the wavelength. I am not an engineer, BTW. But while this guy seemed to know his stuff in terms of horn construction, I think he overlooked the fact that his space is probably too small for a horn of that size to be effective.

Now if you have a 40 or 50 foot (+) long room...then yeah, a large horn would probably work nice.

For those of you that have the larger Klipsch horn speakers probably noticed this effect too and that they sound better in a larger room.

To me, what this guy did is clearly overkill for this application. But I think he could make a nice pair of horns for the local theatre!

Wow, that is a serious set up. I would be afraid my cat would crawl in there and come out scrambled.

Quite right. When I was setting up horns for a school one time and I leaned against the front of the horn (to reach something over to the stagehands) while it was almost at full power, I could see (and feel) the air pressure move my pant legs.

One time a nutball of a videographer, decided to set up his camera right next to a horn. Naturally the bass output 'shook' the video image on his camera.

So horns can pack a punch. While my examples were of a 1200watt amplifier on a set of 4 18" Cerwin Vega L36P folded horns, it is still not a good idea to have a pet crawl into a horn even on a 10 watt system. I have seen some very well designed horns that can hit 110db spl at 1w/1m. That could certainly damage a pet's hearing if they actually got into the speaker.

I do have to give kudos to this fellow's crafsmanship. If I had a theatre with mostly wooden accents, I certainly would like this guy to make a set of horns for me!

For the average home though a much smaller folded horn that takes up much less space can still work wonders.

Somewhere once long ago, I remember seeing somebody who had engineered his horns into the floor of his home, with the drivers above ground and in a closet, feeding concrete horns that wre poured as part of the slab! The mouths of the horns exited at floor level on eitherside of the listening area. That is dedication!

First time I see this pic

That's... either brilliant or absolute lunacy

Cheers!

You must be referring to Roberto Delle Curti's "Varese", the largest (?) subwoofer in the world.
