    This is the nicest piece of equipment I have it is so cool looking and compact it's works great simple to use. The crossover is nice, you just flip one switch and boom you got bass, I really like how it's designed to run a subwoofer and a top box because I have a bunch of different speakers but not like a pair of any so this perfect for me my PXA-840 is running a Stellar Labs 15 inch subwoofer and then the Stellar Labs 10-inch top box also the Stellar Labs pole which absolutely incredible for only $5.I love Stellar Labs
