Depends on which series of A2 you are referring to. I owned a pair of A2x speakers for a couple years. They were 20+ years old at the time. SoundLAB does not currently produce any new A2 speakers. The A2s that I owned had two seperate, but integrated panels. One panel for bass and midrange and one tweeter panel. They sounded best when using a conventional subwoofer to add dynamic range. The tweeter/midrange was excellent!
