I understand the VTF 2 can go lower than published on the website.I have owned 2 of them and still have one.But for someone that only looks at the specs on the Hsu website they will see it reported as 25hz in max extension mode.Just like the STF-3 I have,its stated for 25hz tune on the website and I know for a fact it has strong output at 20hz.I was just stating what Hsu says the specs are.
