There have been several posts on SPL readings and Reference levels on HT systems, some of which I have initiated, on this board over the last couple of weeks. Much of this information has raised some questions for me and what it all means. As mentioned in earlier posts, I have my system set using the Ref30 test tones to 74dB on all speakers with the sub set at 72dB to compensate for the SPL meter I use. When I use the AVIA disk test tones and turn my volume to 0dB on my preamp I get a reading of 84dB on my SPL. All of this seems to indicate that my system is set Pretty close to REF levels. However, isn't this all relative to how hot a DVD (or CD) is mixed. For example, I am sure everyone has noticed that some DVD's (and CD's) sound lounder then others when played at the same volume level on the preamp (differences are much more apparent in general dialog on DVD's rather then during explosions). The SPL meter bears this out by showing a higher dB reading for the hotter DVD's (CD's) using the same volume setting. What this would seem to indicate to me is that Reference levels are only relative to the specific DVD (CD) that you are using at the time and not to the system as a whole. Even if you set all your speakers to 85dB (Avia) and/or 75dB (VE) you cannot just set your preamp's volume to 0dB and expect to get accurate reference levels from your system on all DVD's (CD's) because one DVD may be much hotter (or softer) then the next forcing you to manualy adjust the volume accordingly.
If this is correct then it would seem much more important to balance all speakers in your system rather then placing to much importance on the 75/85dB standard and then adjust your volume to Reference levels (or more importantly, the level you enjoy listening to). Am I understanding this all correctly? Any other thoughts on this would be appreciated.
