Dear all,

I'd like to showcase a project from a friend using the PWR_ICE125 modules.

This February Teufel (German speaker manufacturer) together with Klang&Ton (German DIY magazine) initiated a speaker building contest. A stereo set of chassis from the "Teufel Ultima 800" incl. passive crossover was handed out to 10 enthusiasts throughout Germany. Each participant was asked to build speakers using some or all of those chassis.
The Ultima 800 uses Wavecor chassis throughout (don't know the exact types):
1 x 30mm tweeter
1 x 3" midrange
2 x 6" woofers (4 Ohms)
4 x 6" woofers (~12Ohms, used as passive radiators with optional damping in the Ultima 800).
So all in all quite a lot of material to work with ;) Let's see what all the participants will realize :woohoo:

My friend decided to use the 4 x 12 Ohm woofers in a compound arrangement in a closed box in order to realize a deep bass (tuning frequency below 30Hz). Also the two 4 Ohm woofers are running in a closed box. He used the original passive crossover for woofer/mid and mid/high crossover.
The PWR-ICE125 module is used in the 2ch configuration (2 x 125W). First channel is powering the compound arrangement and the other channel the woofer/mid/high part of the speaker. The DSP gives some flexibility to do some EQ and to do the crossover for the build in sub (compound arrangement).

And now some impressions:

Before the actual competition speakers will be professionally painted once again and there will probably be some fine tuning of the EQ. Let's see how it will perform :woohoo:
