Nice one Karl.

Thanks!
It follows your projected plots quite well, doesn´t it?
Or is it perhaps even better?

Those are unbelieved frecuency responses!

There are a lot and good DIY loudspeakers systems but yours are in the very special side.

Maybe some one who knows better the software can tell us if something is wrong over there. Its there a 1/24 octave resolution?

In the other side, in the subjetive side. How do you describe the sound scenario?

The performance of the speaker makes a wide and deep soundstage?

I'm very, very happy with it.
It has a very clear and natural sound and it's best feature is the soundstage. It is impossible to tell where the speakers are in the room with shut eyes. When you play a good recording from a large room - you are in a large room.
Voices and string instruments are unbelievable.

Almost smack on with what MathCAD predicted.

I just happened to do a distortion measurement.
Unfortunately I am not aware of any standard reference level i db, I just measured it playing..well, loud.

Do you have spectrum charts? And what amplifier?

No, but I think I can do some.
Tomorrow. Wife is sleeping now.
What exactly do you mean with spectrum charts?


This is run through a passive Promitheus preamp and a Nuforce Ref9 amplifier.

A spectrum shows the amount of each harmonic. What you are showing is a THD measurement collapsed along the spectrum dimension (for the amplifier/speaker system) and it gives us very little meaningful information. Slicing the 3D chart at a frequency gives a spectrum vrs distortion amplitude chart that tells more. A 3D chart with spectrum, frequency and distortion amplitude would be even better.

What software can accomplish that?
I'm looking in the menus of ARTA, but I can't find those particular features. Which of course doesn't mean they are not there...perhaps I just can't find them.

This is the best i can do, I guess.
I've done this measurement outside which resulted in much lower distortion. These are on-axis measurements from 4 feet.
