With twin 165mm bass drivers and a 46mm BMR in a 40 Litre enclosure, the S-400 is designed for more modest listening rooms and can be used with less ambitious Naim amplification. Low frequency response still reaches down to 36Hz however and the S-400 gives only very little away to the S-600 in terms of dynamics and maximum level. The S-400 gives nothing away in music making however.
For more technical detail please read the white papers available for the Ovator S-400.
