Rives Audio PARC


This product has been around some years, anyone know of any similar device or perhaps better? I have read a bit and it seems as some like it and some less.
I have the option of buying custom built bass-absorbers, but they are extremely heavy and large. So i am looking at options.
I use only cdp + active speakers, fully balanced.

What is your goal? If it is general EQ and room matching, physical treatments are always preferred but, admittedly, they can be extremely large for bass modes.

Assuming you have only 2 active speakers (no subs), you would be best served with room treatments for everything above the bass and EQ only for the bass but this is difficult to implement in an all-analog system. The PARC will be a big help (http://www.stereophile.com/roomtreatments/883/index.html) but there are much more effective digital options these days.
I have 18 Gik acoustic devices and i do have a pro company building true bass absorbers. They work and you can set them at a specidfic frequency. But again, very large and very heavy. A PARC is small and i can use it with ease. Question is, what are the downsides?
