Analog room correction for vinyl


There seems to be quite a lot of dsp based room correction for digital but what are some analog solutions for vinyl systems? 
Thanks

chakster, there are certainly reasons to use room treatment. There are areas where it will work better than digital correction. As for standing waves digital correction will make the frequency response at the listening position flat but as you move away you are still going to get the same undulations maybe even worse at some places. Avoiding this requires room design and appropriate sub woofer set up. All this works together to achieve the best results. What DSP gives you, complete control over the entire frequency range, accurate time alignment between speakers and drivers regardless of their position in the room and complete distortion-less control over crossovers can not be done any other way. I use all three methods, actually four. I use speakers that have inherent in their design less interaction with the room, a room designed for flat bass response, room treatment at critical first reflection points and DSP control.  www.audiovero.de/en/acourate.php I encourage people to go here and download trial samples of the program and play around. 
You may want to look for ten or twelve band equalizers (or better yet parametric equalizers) from the 80's - 90's.  You can patch them into your system and equalize for the room without digital.  Not as versatile nor accurate as digital equalizing, but with no digital side effects.
DSP is great if you are domestically challenged. If you have flexibility the room acoustic treatment is better. 

It is not true that ALL soeakers are not well matched. My speakers are extremely close.

some need to stop gulping the kool-aide.
Excellent thread.
if you want a ‘room correction’ device try and find a Rives PARC it is all analogue but calculates in the digital I think - not just that but it works primarily in the bass where you get most room correction issues. Failing that consider subs by the likes of velodyn that do room correction. In the mid and treble room treatment is the way to go. If getting time alignment of drivers is what u need then go digital - you can do more with it. I am primarily analogue but I never dismiss digital
No acoustic treatment is going to solve bass issues in a room. For analog correction this is the ticket:

Measure your room with REW and a calibrated mic and then correct the biggest peaks in the region below 200Hz with the NSEQ
