HSU amp class ?

[Peter Marcks]

Dear jester,

The separate 500 watt external amplifier that we sell (for use with TN1220HO and other subwoofers) is a class H amplifier. The amplifiers that we used on the original VTF-2 and VTF-3 were class A/B plate amplifiers. We now use BASH plate amplifiers in our box subwoofers, which can be considered to be a hybrid of fidelity of Class A/B amplifiers and efficiency of Class D amplifiers.

Sincerely,

thanks Andrew and congratulations on the new miracle

Likely class D like most subwoofer plate amps.

I'm a newbie and would like to know what amp class HSU subs use.
