On Midrange drivers - the whys and whens

[system7]

2 WAYS are not simple, most of time they are loudness, there is a trap in the mid the measurement doesn't often show... and you can hear that in your room...
...I think the 3 ways is the solution for most all of us... but I'm sure there are very good designed 2 ways...

I think it IS possible to make a good two way! There are tradeoffs, mainly in the bass extension because you can't use too big a woofer easily. The time alignment also sucks on a flat baffle with a big woofer.

But let me reiterate this genius WLM La Scala loudspeaker which gets lots of bass from an 8" unit:

An externally hosted image should be here but it was not working when we last tested it.

How do I know it is good? Well, actually, I have something near as dammit running in my test cab...😀

That TW 70 cone tweeter is ACE. Why? well, let me quote Robin Marshall:

Atkinson: You say that you think a cone tweeter might be a better way of going about it?

Marshall: Yes I do. Because when a dome goes into breakup, it's utterly, totally finished. Uncontrollable. That's it. There's nothing more to be had. When a cone goes into breakup, all that's happening, providing you can control it, is that the radiating area is diminishing. It's much easier to control that.

...Marshall: Oh yes! That's where soft domes fall down, I think. They spit and sizzle at you, but when you look at the response you think, "I don't understand it. Why?" If you simply think about what the thing's doing, it's obvious, isn't it? This awful resonance in the audio band.

And it's true. The TW 70 cone has limited dispersion, but it sure sounds smooth and detailed. No spit and sizzle. As it goes, I have another project in mind for the TW 70, but it sure is GOOD in this application. 😎
