I have just seen your reply on the forum : needless to say I'm more than interested in what you can tell me, first about the oris 150 second about the 10pi. I must visit bert doppenberg on Monday 22 : I will discuss the option of the Pi as a bass speaker and let you know what he says if you are interested!!! Have you tried other options before the 10pi, like the cabaz, onken, scala... suggested by Bert?
Have you tried the 10pis alone or not? Why did you decide on using them together? Any shortcomings in either speaker??? Your experience would help me make up my mind!
what gear do you use to drive them? Advice welcome since I'm starting a high efficiency system from scratch.

Looking forward to your reply

Gilles.
