1st order crossover?

The speakers I have, have a 2 inch dome driver that has crover points at 1,000 and 2,000. In the owners material and set up a lot of attention is given to phase and time. Each driver is in it's own cabinent and a measuring device is used to align each cabinent after measuring the seating position from top of sub and floor to ear distance. Can the crossover points for that 2 inch dome be 1st order "6db per octave" when it is not even covering an octave. It has been said that drivers for 1st order crossovers have to cover such a wide frequency range. That is not the case here. Hope to learn a few more things on 1st order crossovers. Thanks

I will list all of the crossover points. 120,1,000,2,000,and 6,500. I like the speakers a lot. I am just curious about the 1,000 and 2,000 points. If there are knowledgable folks out there that can shed some light on this matter I would appreciate it.
Thanks Jeff

They are Essence 10As. Yes I have asked but Dale keeps the specifics of his designs to himself. The owners material does say the crossover is 1st order and "This is the only filter that is both phase and amplitude coherent." Have owned the speakers for 12 years. Had them updated once. Have always been wondering about that 1,000 to 2,000 part of the crossover. These are my favorite speakers. I also like Vandersteen and Green Mountain. I know that just because the crossover points are far apart does not mean that it is 1st order but when it is this close can it be 1st order?

Yes it is the same Dale. He makes great products. Have not heard any of his Intuitive Design products, but really liked the Essence stuff he made. Thanks for your input guys.

Hi Honest1. It sure is an unusally small range. What ever it is he did he did well. They are Essence 10As.
Thanks Jeff
