      Advantages

      Disadvantages

      I have been testing Sub Woofers for sometime and have seen the changes in their design over the last few years. The pentagon shape that Sony has opted for in their new sub woofers is quite ingenious and does look quite striking in an ICE install. The test performed on this particular sub woofer was done in a simple sealer enclosure (designed for this particular speaker) and was run on a powerful 1000W (RMS) amplifier (this is used for all my testing). Sony has rated the speaker at 1200W peak power (350 RMS), which is quite respectable for an averagely priced speaker. The sound is tight and gives both a good punchy sound as well as smooth deep when it need to do your insides some damage. The increased rigidity of the pentagon shape does help in high wattage applications and the Injection molded Polypropylene cone is lightweight and seems quite durable. Overall, it is quite a good subwoofer for the novice enthusiast. Problems that I have had revolve around the design of the pentagon cone, which limits the excursion, and flex of the rubber surround. The creases that have been used at the points of the pentagon cause issues when operating at high wattage low frequencies. The design limits the efficiency of the speakers? ability to move back and forth evenly. Traditional circular designs have an advantage, as the rubber surround does not restrict any part of the speakers? movement from extreme back and forth movements. The natural resting position of the pentagon (not powered) is where the rubber is quite relaxed, low wattage is also quite easily run through the speaker without any real flex of the outer rubber edge. When the speaker is moving from one extreme excursion to the other, at high wattage, there is a definite problem with movement that can actually be heard and does inevitably cause distortion. Not all users will be using the sub woofer at this level and may not even notice this problem, but it is there. After some use and the &quo
      t;breaking-in" period is over there should be less of a problem, but I would not suggest this to anyone serious about Bass reproduction. The sub is well above average in performance, looks stunning but not really my cup-of-tea.
