Bhull,
From your description, there is a possibility that your VP150 is faulty. Among the things that can happen (rarely) in shipping are dislodged push-on speaker connectors inside the enclosure. If it were the latter, the driver(s) would either work or not, and you could easily check by removing each driver from the front baffle and ensuring that the connectors are secure. Once in a while the crossover board may develop a crack from blows during shipping and that might lead to intermittent operation of some of the drivers. It's really rare, but it has happened.
There have been reports of channel failures and shutdowns of Emotiva amps on these boards and elsewhere, and I have one acknowledgment from a professional engineer and reviewer that the Emotiva amps have had "issues" with channel failures in the past.
If you return the VP150 (arrange that with JC), we can do a forensic examination at our lab and determine if there was an inherent problem with the drivers and/or crossover.
I really regret you've experienced this with your first home theater system and I assure you Axiom will set things right at no cost to you.
Regards,
