The front view of the Mark I. The original SNR-1 is on top. The twin 10" aluminum woofers sit underneath.
Below is the rear view, showing the tweeter and mid-woofer connections on the back of the PW-1's cabinet. Note that the bottom section has a 3-way Class D amplifier. The speaker jacks on the bottom cabinet are amplifier outputs.
The SNR-1 were originally intended to be passive speakers but with an external crossover. In this case, the removal of the external crossover and connection to the PW-I was trivial.
The drivers are Dayton Audio RSS265HF-8. They are 10" aluminum and in this sealed cabinet would do 40 Hz alone. I had the choice of doing 1 10" woofer, ported to get to ~ 25 Hz, or 2 sealed and I went with sealed for the higher output, lower distortion, and lower group delay. It did need a little boost in the DSP, but I have so much output available in my modest living room this was trivial. Also, since this is now tri-amped I can afford to give the bass more power and still have another 250W for the mid and 100W for the treble.
