I ordered the sbs-01's and matching center.There has been so much positive feedback on both,Its a tossup.
As an SVS owner, I can tell you you're going to get more than your money's worth with these little speakers. Though small, they fill up even a moderate sized room and reproduce great sound throughout the entire frequency range. Plus, they're built like tanks - seriously, solid with excellent internal bracing! That said, they don't dig very deep into the lower frequencies, you would still need to pair them with a good sub to get the best overall effect. Congrats!
EDIT: As for pairing with a sub, if you do this - shoot for 80Hz on the crossover point - for me that seems to have worked extremely well within the limitations of the SBS-01's, and provides for a very smooth blend between them and the sub. Since you didn't mention what you really plan to use them for I'm just tossing this out as an FYI - they're great speakers, but still bookshelves after all - if you want deep bass you're going to need a sub.
