Stopped by the local B&M this morning looking for a small footprint, 8 inch, tight musical sub to compliment Paradigm Atoms in a small room. Use will be 90/10 music/HT. They showed me a PSB Alpha SubZero. While it has only 50 watts it sounded pretty decent to me in a fairly large demo room. List is $300, and they would sell it to me for $250. I only need bass extension to 30 Hz or so and real loud is not a big factor. Musical integration with the Atoms is the most important factor. I am seriously considering getting it. Does anyone own one or have comments on this sub? Thanks. Regards, Nick PS Another alternative would be a Paradigm PDR 8, which as of yet I have not auditioned. Comments on the PDR 8 or other recommendations are welcome too.
