"... the Caldera 10 added a whole new dimension to the sound giving resonance to the lower piano notes and depth to the drum beats."
"The Caldera 10 worked seamlessly with the Vanguard Loudspeakers, creating that in-church feel that only a sub can reproduce yet sounding as if it were an integral part of the satellites themselves."
"I cannot recommend the Veri-Fi Audio LLC Vanguard Caldera 10 Active Subwoofer enough, buy one, for $200 it is a no brainer, in fact, buy two, or if you want to use them for home theatre buy four, no $800 subwoofer will come close."
