#1 WHY SUCH SHAPE?
Shape of the enclosure has a vital role in the performance of the loudspeaker. Moving of speakers causes sound waves with very complex mixture in terms of frequency, amplitude, phase etc. If the shape is rectangular with parallel walls at certain frequencies two bad things may happen: the walls will start to vibrate due to interference and they will act as additional speakers, but without control. So the general sound will be unpredictable mix of the sound caused of the speakers and box’ walls. Second: standing waves will occur inside the cabinet which will raise enormously certain frequencies and will defeat other. This is why we use quite complex shape of the Aurora II enclosure. In addition to the shape the material we use is very solid and robust.
#2 WHAT DO YOU MEAN WITH UPGRADABLE SYSTEM??
Aurora II can be added to your system later. You can buy Terra or Luna speakers initially and then to add Aurora II. The connection time is for a minute. In addition you will not need a stand.
# 3 CAN I USE OTHER MANUFACTURER’S MID-
Generally you can do this. Anyway we recommend for best audible and visible results to use Terra or Luna.
