Why not horns?

Are properly implemented horns that rare? Perhaps, but I would argue that properly implemented high end systems are rare. I've seen a lot of systems in peoples homes that despite their best efforts just don't sound all that good. Most people don't understand the interaction of the different components and selecting input and output impedances that work well together, picking the right amp for a particular speaker, how to integrate it all into the room, and the list goes on. It's not easy. I think it would be very easy to audition a number of horn systems and come away blaming poor performance on a particular aspect of the system when it was actually something else.

Like I've said before, it is a shame everybody can't get a chance to audition everybody else's system. These threads are fun but they settle nothing until you can hear what the person is talking about.

Herman, well said.

Unsound, Herman and I agree on something :)

Herman, The reason the Trios and probably Duos have such an impedance curve has to do with the way the crossover works. Let's use the Duo as an example, but this is only an example, my experience with the Duo (even though a lot more of our customers use them than Trios) is limited.

So we have the main horn and let's assume that it is 8 ohms. Then there is the tweeter horn and it is 8 ohms too. Now if there is a cap to keep lows out of the tweeter, what happens is that at low frequencies the amp sees the 8 ohms of the main horn. Since there is no choke to keep highs out of the horn, the main horn will be in parallel with the tweeter at tweeter frequencies. So the impedance drops to four ohms because the amp has to drive the main horn and the tweeter too. The Trio uses an expanded 3-way version of this scenario.

If there is a crossover offered that has more than caps in it I think it will be a big step forward for that speaker!

Atmasphere, we may haven taken different paths in the woods, but we're in the same woods.:-)

With a frequency response of 300 Hz. up to 14 Khz. from a single distortionless driver, it seems like a no-brainer that everyone would want this performance. Why don't you use horns?

Because I get this and more (useful 60hz - 14,000hz) from my single driver speakers with no horn reflections/ colorations in a much smaller package to boot.
