I have owned my home theater now for about six months, and I just today stumbled upon yet another piece of equipment people say one MUST have....the Radio Shack SPL meter? (I am not sure if this is the correct name) I was told that all sound levels of your speakers should be at the same volume. I at first had my center channel at 8 out of 10, my fronts at 7 and my rears at 10.....I like rear effects the best. I told someone i had these levels as so, and they said the levels should all be at the same, so I changed them all to 10. Now, I read that I need this meter, so does this meter basically change these speaker levels (rears might be 8 while the fronts might be 6 etc) or does it change them all to the same level they should be (not necessarily at 10 all the time) Is there a level that most of you have your speakers set at that the majority of movies sound great on, or is 10 for all of them too high? I would definitely go buy this meter, but money is tight right now, and I need to know what to do in the meantime to get by. Thanks for any information.
