Rives PARC parametric equalizer

Not only does the PARC alleviate modes that are untreatable with bass traps, ASC Super Traps in my case, reducing those modes significantly opens up the soundstage and transparency and improves elocution significantly.

I use the PARC and it's the best component in my system.

I find it very transparent and agree with Lenny_zwik that it can open up the soundstage. Getting the bass right has a lot of benefits.

thanks for the comments.

With my room - LP cabinets all across the back wall ( behind listening position) and front right side wall make room treatments / bass traps difficult without major changes.

Using the Rives CD, it would seem that my main bass problems are around 40hz (+8db) and 100/125 hz(+12db). Using a cheap behringer Ultra-Q T1951 parametric eq, it would seem that the 100/125 hz causes the most noticable boominess on most music. reducing the 110hz by 7db has helped quite a lot. Still playing around with it.

What acustic treatments are good for the 100/125 hz area's?

ASC Bass or Super traps is what I've used.

Long time this tread was initiated.
But, i must say, using PARC with XTZ Room analyzer PRO II and additional Gik acoustic devices (TRItraps(corners) and 242/244 panels(behind speakers and first+second reflection in ceiling) is nothing less than breathtaking.
The PARC when exactly calibrated (easy and exact with XTZ RA PRO II) does things no absorber(s) are even close doing. Voiding the flutter echo and bass mumble even further enhances all (Gik acoustics devices).
I marvel, this is among the best i have ever heard....
