With the 703 S3 3-Way Floorstanding Loudspeaker you get what is basically a slimmed down version of the 702 S3. You get the same great external tweeter, the exact same high tech midrange driver and two of the Aerofoil woofers instead of three. They are a big jump from last year's model as that one had the tweeter mounted internally.
The cabinet is slightly smaller and in this model the port is rear firing. These have the same sensitivity as the 702 S3, but our same comments would apply for power.
