I own the VP 100 and have never heard the VP150. I think the 100 is great it sounds virtually like the same as my M22's and QS8's. I have a realatively small room at 12X16 with the end open for another 10ft. I sit about 12ft away and it centers the dialogue perfectly when watching movies.
Check out my pics at www3.telus.net/public/jklasher/. I think you will have no 'what ifs' once you here it. Relax Axiom doesn't sell anything that does not sound as good as any speaker they produce. No upper or lower ends as other companies do.
