Yes, Jim, you qualify. On the sub point, maybe you can describe in more detail what you're wondering about. Just throwing out some general points: maybe the calibration was about right, but you were expecting to "hear" more from the sub. Many set their sub level too high; the general idea is that the sub shouldn't be apparent as a separate source, rather that the impression should be that it isn't working, but the other speakers are putting out more bass. Other thoughts are that an 80Hz crossover is generally considered a good compromise and a corner is often the best location for the sub. Glad you're enjoying your Axioms.
