Old Creative Computer Speakers

I've always graphed speaker that have been considered good or great by many audio enthusiasts.  Just for comparison I did a set small computer speakers.

I chose these little Creative speaker simply because someone I know has them in everyday use.

I didn't move the speaker around as I normally would and I did them fullrange in my QuasiAnechoic Chamber.

Well here we go:

  Tone controls adjusted for bass emphasis, Flat, and for treble emphasis:

Overlaid:

Time domain stuff:



This time I decided to make impulses of this speaker so that others might be able to get a glimpse of what these sound like by using the convolution process.  I accidentally bumped my microphone in the process so I rechecked to see my new measurement and then I'll compare it to the measurement of the impulse:


Pretty much identical if I could get them to size up exactly.

Anechoic Chamber


That's a waste high view from the entrance
It made of Roxul covered by local fabrics.  Approx 2meters cubed. 

ADAM A3 for first go round with stuffed ports


All well and good, but what's in measure in there?
