801D4 - you can add subs at any point later on if you find you need more bass.
Although the 802D4 shares the same midrange enclosure and tweeter as the 801D4, Bowers has done some magic on that xover, midrange driver, and woofers to separate it enough from its lower sibling. The 801D4 when i auditioned it had a much effortless and fuller sound. Besides the deeper bass it was the midrange that stood out enough.
