Nice Job
I have always wanted to hear the orion system but have never had the opportunity. The open baffle is of interest. I use active crossovers in my system as well and I am happy with the results. Certainly not mainstream on these boards but I assume this isn't of any concern to you as you built the Orion system.
I am familiar with the constuction of these speakers however, I have never seen anything like yours. Your baffle looks like it is constructed from a tube rather than one plate. I like the idea of plate rather than wood and if I ever build them I would probably make them from plate stainless steel. I am also confused with the subwoofer attached rather than built as as separte unit. Doesn't this interfere with the open baffle concept for all the drivers on the main baffle? The same goes for the tube concept of the baffle. Doesn't the back of the tube interfere with the open baffle concept?
I am extremly interested in your comments.
