Equalizers anyone?

I have been using the cello parametric equalizer,found it very useful for adjusting for poorly recorded cds.easy to use a wondeful addition to a system.But does not solve the room accoustics.

The Rives is a very different product from the Accuphase which in turn is very different than the Cello. Each is a good product, but they are optimized to accomplish different tasks. You'd get better responses if you stated what type of room deficiencies you're trying to address.

My experience with equalizers (none as sophisticated as those mentioned above) is that they can alter (improve) the sound of recordings, and change a speaker's frequency response, but room resonances stubornly persist, regardless of how you push the controls up and down.

My fix for room resonances is the use of planar speakers. In my room, (quite large and very irregular in shape) with three MG1.6 and three subwoofers, room problems (that I had before) have pretty much gone away. Maybe it's just luck.

I use a z-Systems RDP-1, with three of the 4 paramatric controls providing cuts in the low to mid bass (thus similar in a sense to the Rives), the low shelving control for a slight boost below 35hz, and the high shelving control as essentially a program-specific treble control. I wouldn't be without it or something similar (though of course as it is all digital I am restricted to Red Book sources or analog sources digitized with my z-Systems ADC). No downside that I can hear.

My room is quite small, 11 x 13.5 with 8 ft ceiling. All plaster with heavy carpet and pad over hardwood floor on 1x6 subfloor. I'm getting somewhat boomy bass with some sort of echo slap and I can actually hear the room affecting upper mids and lower highs. I can literally hear the room doing these things as the volume gets louder.

I know the PARC is only an analog bass correction system and the Accuphase is a digital all frequency 'tuner'. I've done two types of room treatments and tried every speaker placement possible. However, kind of restricted as to room treatments because of WAF factor. I'm thinking one of the better equalizers could help with my speaker/room interface.
