There are ORION owners and DIY builders in many parts of the world:
Argentina, Australia, Austria, Belgium, Brazil, Canada, China, Croatia, Cyprus, Denmark, England, Finland, France, Germany, Hong Kong, Hungary, Iceland, India, Indonesia, Italy, Japan, Kuwait, Latvia, Lithuania, Malaysia, Netherlands, New Zealand, Norway, Philippines, Poland, Portugal, Rumania, Russia, Singapore, Slovenia, South Africa, Spain, Sweden, Switzerland, Thailand, Turkey, UK, USA (AK, AL, AR, AZ, CA, CO, CT, FL, GA, HI, ID, IL, IN, KY, MA, MD, ME, MI, MN, MO, NC, NE, NH, NJ, NM, NY, OH, OK, OR, PA, SC, TN, TX, UT, VA, WA, WI).

Note that for privacy reasons I cannot give you the name of someone in your area, who you might want to visit, so you can listen to their ORION system. Check out the list of people who might be willing, or try to make contact via the ORION/PLUTO Forum.

Here are examples of their work. A few builders have chosen to change the ORION's cabinet shape to fit personal preferences. This leads to measurable deviations in on-and off-axis frequency response from the target response for which the cabinet was optimized. I cannot tell you to what degree these speakers are audibly different from the ORION, but their builders are very satisfied with the sound.

What you hear is not the air pressure variation in itself
but what has drawn your attention
in the two streams of superimposed air pressure variations at your eardrums
