I recently survived a re-carpeting of my dedicated listening room. I decided to reorient my speakers (Vandersteen 5A's) from a previous, excellent positioning. These speakers have an on-board LF amplifier with analog equalization at set frequencies. The set-up regime suggests first positioning for the most accurate presentation for frequencies 150 Hz to ~20k Hz. Having done that to great success, I then go about adjustments to various stepped frequencies from 20 Hz to 125 Hz. All is well except for a dramatic room node at 100Hz in my left channel. No amount of related frequency step adjustments can tame that +10 dB plus (using the Rives frequency CD) mode.In my prior set-up I used the Jim Smith recommended regime of placing the speakers in the best LF position as heard from the listening position, then working to optimize frequencies above 150 Hz with slight adjustments. That method was very good with excellent tonal presentation and an okay sound stage, but some indefinite localizations of instruments and an unrealistic placement of singers at about 4 feet in height. It did not present the excellent, beyond belief sound stage, height and presence established by the method I described above.
I realize all things in home audio are to some extent a compromise. So, I set about trying to locate a Rives (analog) PARC parametric equalizer to no success. I've checked the pro-audio online shops and most of those offerings are either tube, digital, of suspect quality or way more functional than what I seek (i.e., over $2 grand).
Is there anything that can attenuate or reduce that 100 Hz in the analog realm with balanced ins/outs?
If not, is there a DIY solution that I can explore?
Cheers,
Ian
