I just started auditioning my new pair of S2EXs (swapped after demoing S1s)....my Marantz AV7705 Audyssey declared them full range! I did a lot of listening and while adding the sub back into the mix was clearly better - the S2EXs held their own for an awful lot of music in a medium sized room. I've got a lot of listening still to do, but bass extension here is impressive so far.
