Re: SRX718 to 'what powered/active sub?'
Douglas,
One can assume a sub is rated in half space unless it has rigging points and a chart specifically states full space. Testing a sub in full space requires it to be several wavelengths from the ground at the lowest frequency to be tested, that requires a very tall crane...
As you noticed, the Mitus 118SA peak rating is for 2ms burst, less than 1/10th of a 36 Hz cycle. Even the 500ms (one half second) "continuous" rating is a bit light, synth players can lean on a low note a lot longer than a half second.
The "Electronic Specifications" show 36 Hz at -6 dB, obviously the result of one of the presets used to tame the bandpass "hump in the middle" raw response.
Still, for 2 grand, looks like a real box with a real speaker and a lightweight amp.
