I called a couple of hours ago, and Dr. Hsu actually answered the phone , and was advised that they are discontinued and no more will be ordered, brought in. He suggested the 2.3 which is only 1 - 1.5 dB lower that the 3.2. HTH
I believe this is true. I needed a maple sub to fit into our room and was looking for a 3.2. I was told the maples were gone and would not be available anymore. When the blacks were gone that was it as well. I ended up with the 2.3. The $60 seemed like not much for more power but now it appears that it is no longer an option in either finish. I really like my 2.3 and feel it is plenty of power for my tastes.
