SB-4000 and PB-4000 Subwoofers Receive Heimkino's Reference Class Award

"The SB-4000 subwoofer convinces with a crisp, precise reproduction of lowest frequencies. For the ultimate pressure in the diaphragm, the PB-4000 is particularly suitable, because it provides even greater dynamic range and maximum low frequency extension...With the new 4000 Series subwoofers, SVS once again hit a home run. Both models offer maximum low-bass performance at reference-class level."
