recommendation of a sound level meter



I currently have a pair of Quad 988 loudspeakers, Thor Audio TP 60 monoblocks, Thor TP 2000 preamplifier and a
Cary 306/200 CD player. I am attempting to cure the
problem areas in my listening room. At this point I am not really sure what they are. It was recommended that I purchase a sound level meter to help me. Can anyone recommend a sound level meter besides Radio Shack that is
very accurate and reasonably cost effective. Thank you for any light that you can shed.

What are the corrections for above 1k (where it gets REALLY inaccurate!)?
Thanks.
The full corrections are published in our instructions for use manual. If you go to our software page and download the instructions for our Test CD, there is a chart that gives the RS values. This was for the older 2050 analog meter. We have done preliminary work with the new 4050 meter and it appears to perform the same.

Rives,
Thanks a bunch! Pp 3-4 should be required reading for all A'goners. I'm surprised a bit that the RS's treble peak is relatively low Q...it's a better mic than I thought.
Thanks again. Ern
Rives, thanks -- nice site by the way. I had two or three different adjustment factors for the RS meter. Your correction factors line up exactly with those Sean posted a few years ago. Now I finally know which to use. Now if I could only get my system down to 10 Hz ;-)
Rives, if my understanding is correct, your CD is made for stock RS meter. Does it mean that it's not usable in case I'm using an external mike?
