Troels Gravesen is not very impressed by the Lowther EX3... I do agree with him.

With my lack of knowledge on the subject,

It seems that a driver with a rising frequency response would work fairly well in a front loaded horn that displayed CD properties ???

Or any driver needing HF attenuation for the desired response. I used this to achieve the transfer function I was looking for in my 2 way, as the phase was best matched without an electrical filter on the woofer.

Lowther EX3

I don't know about you guys, but the distortion graph provided by Troels Gravesen looks absolutely horrible! even for the cheapest speakers you can get from walmart!

My guess they sound good due to the price tag

Listen to what he says and look at the off axis response.

I have not listened to these speakers, but I have listened to many speakers with different harmonics distortion profiles. So looking at the harmonic distortion of a certain speaker gives me a good idea of what it'll sound like. I think what Martin King and others find so magical about these speakers is due to their high ( IMHO unacceptable) 2nd order harmonic distortion.
I think Troels Gravesen did not like Lowthers, because he is used to using high quality scan speaks and seas drivers which generally have very low harmonic distortion.

Did you do this blind. As in before you saw the distrotion curves?

Geddes studies have shown the distortion needs to reach some serious levels before it is audible.
