Why not horns?

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.

As I have said, horns do Dixieland jazz superbly, but I can't listen to Dixieland all the time.

Thanks for setting us all straight on that crucial statement, I will now have to sell 99.9% of my collection.

Thanks Ralph, that makes sense but I wonder how it affects the sound? I have the high impedance drivers so the mid and tweet in parallel won't go below about 8-9 ohms at the high end assuming a resistive load. So it seems to me all my amp has to be able to do is maintain the output voltage into 8 ohms. That seems easy enough.

Getting ready to spin my copy of the Dukes of Dixieland "Barn Burner" since I now know it is the only thing that sounds good on my system.

Glad I don't have planar speakers. I guess the only thing that sounds good on them are flat instruments like the washboard and the gong.
