While I agree IN THEORY, I think the jury is still out on Trinnov's effectiveness on LF content, particularly multiple subs or problematic rooms. The folks at SVS, for example, would probably claim their sub equalizer can improve LF performance over and above full range equalization systems such as the various iterations of Audyssey, MCACC, etc.

But I sure hope Gonk is correct, as this would mean buying a stand alone LF equalizer is not necessary with the 998.
