Well, that is -- dare I say -- really poor implementation from Pioneer. Sure, standing waves can be a problem in the 63 Hz to 250 Hz range, but they also can affect the 20 Hz to 63 Hz range. To create a so called Standing Wave control but then prevent it from operating over the lowest octave and a half where standing waves are prevalent is quite puzzling. I wonder if this is Air Studios' doing, if it has some half cocked philosophical reason for applying no corrections below 63 Hz.
Glad you got the confirmation you were seeking
I just checked in today, been out & about today enjoying some sunshine
Yes, you can apply standing wave notch filters to fronts, center, and there's a separate one for sub. But as pointed out, 63 hz is the lowest, and the other 2 go up from there. I believe Pioneer limits it to 63 because it's tied to the equalizer in MCACC, which is limited to 63 Hz.
Plus, as helpful as notch filters might be, you must admit they are not in the same league as a full bass range parametric EQ or the time domain filters in systems like audyssey.
I also wanted to mention that I have spoken with Chris Walker at Pioneer on a phone call & he acknowledged the issues with sub EQ & also that independent Xovers could be beneficial to some setups. As he explained it, Pioneer US is just one division and when deciding on changing features, other country's divisions are also involved in these decisions, even then I suspect they would have to convince Pio Japan. Let's be honest here, IMHO, if they don't think they are losing too many sales to companies that have xyz
feature, and that abc
feature is going to gain them far more sales (think apple i-interface
), then that's where the R&D money is going
