Silent Pound Challenger Speakers.

Silent Pound writes: "3 times less room resonances with no additional room treatment. How? From a technical standpoint, the biggest challenge to control directivity is in the low frequency range.  We’ve addressed this issue by building in a gradient type low frequency (LF) module in our system and results were astonishing: 3x less acoustic power radiation to the room (directional index ~4,8 dB) when compared to traditional closed enclosure speakers emitting low frequency sound in all directions."
