La Scala II problem

Just a few days ago I received my new La Scala II's unboxed them and set them up. I noticed that from one speaker there was only a faint music signal coming from the HF box and nothing from the LF. I verifed connections and swapped the speakers - the issue followed the speaker. I pulled the jumpers off today and once again on the HF taps - only a faint sound and when on the LF taps no sound. Tech support has suggested that this may be a network issue, but aren;t these things tested prior to leaving? The boxes were shipped via a dealer so there were no UPS or FED-EX abuse issues.



Any thoughts or suggestion would be much appreciated.



Thanks
