To start, audio quality of the sound bar portion of the system is very good, and inclusion of the the surround effects tweeters are a nice touch, as they definitely serve to widen the front sound stage - make it the sound bar a good match for TVs that may have larger screen sizes - as well as filling the room with fuller sound.
On the other hand, one aspect of the ShockWafe Pro that is innovative is the inclusion of tweeters on each end pointing outwards. Nakamichi refers to these as "surround effects tweeters" and actually do their job well in not only widening the front sound stage but projecting sound well into room.
The additionally provided surround sound speakers performed well when provided the needed audio signals. The surround speakers projected directional sound or ambience cues well into the room, providing a surround sound listening experience that can't be achieved by the soundbar alone. Also the blend of sound from front to rear was very good, made better by the presence of the front sound effects tweeters incorporated into the sound bar.
Using the Digital Video Essentials Test Disc (Blue-ray edition), I was able to hear a faint bass signal beginning at 30Hz
