Hello, Mark. There were many things I was unimpressed with. First off, the room wasn't the best place for a debut....especially for those speakers. The room was built in an old Tweeter model conference room to which the floor was actually raised 3' up above the concrete substrate below. This made for an extremely "boomy" experience, as the lower waves radiated and bounced around considerably beneath the raised floor. Add to that, apparently Sandy's preference that night was to have the bass boosted and not running flat. It wasn't boosted slightly either. It was boosted well beyond that which was acceptable and when you added the raised substrate....the end result was bloated, one note, boom-boom type bass and I personally can't stand boom at the bottom. Full frequency reproduction, yes. Boom, no.
With keeping all of the aforementioned in mind, the speaker didn't seem to blend well at all between the individual drivers. The sub consistently hit harder on the lowest of frequencies than others and one almost had to strain to hear any mis-bass, especially mid bass with any sort of clarity or impact. It reminded me of an improperly implemented car sub with one [low note] bass. The top end was chopped off and what was left was rather tinny and not very detailed. Harsh at times, if you will. I actually made a comment to a friend of mine that I was surprised that Sandy stood beside these speakers with a sense of pride. To be completely honest, I would have been embarassed to stand by these speakers at any price point. Especially in that room that night. I didn't know about any tweeter change with regards to these speakers, so the only comment I say say is that I observed whatever tweeter came out with the speaker when it was introduced to the public.
Basically, I was thouroughly unimpressed with this speaker. It would be a great HT speaker but when Sandy mentioned that it was built for 2-channel, I thought to myself that it would be best to just keep my mouth shut. That's when I went to leave and Sandy asked for my observations. Awkward, to say the least.
