HXOS+ SoundVision (Greece) Review the SB-4000 Subwoofer

“The SB-4000 is a "scary" subwoofer full of energy. From the very first Hz onward, mainly felt in the chest and your belly, to the last ones around the cut-off frequency, comfort and a velvety timbre are the dominant factors. No matter how hard we tried we could not make it reach its limits.”
