    ok i hope i finally got my spl meter yesterday to configure my speakers with my avia disk and i'm having some problems. i understand how to use the meter and all but how/what do i actually change on the reciever to set the speakers (using a sony str-da4es and energy c-7's, c-c1, and c-r1's)? i looked on the avia and couldn't find anything telling me how to do that (hope i didn't miss it on there:b ). sorry if this is a dumb question but it's my first time doing this. ty.

    The first thing I would recommend is giving your receiver manual a read through.

    Each speaker has it's own adjustment, and can be accessed through the OSD. If you don't have the OSD hooked up, it can be done from the front panel. I don't remember the exact sub-menu, but it will be where the speaker size/distance/x-over settings are. You will need to set the speakers to "small", which will give you the ability to set the x-over point for each speaker.

    No, you don't change the x-over to adjust the volume using your SPL meter. You adjust the volume for each channel via the menu that you can find by reading the manual for your receiver thoroughly. Avia does not have instructions for the many different menus on all the various receivers out there. The goal of adjusting the speakers is to get them all to play at the same level, so if you don't care about setting to reference, just turn the volume up a ways, start with one channel, and set all the other channels to that volume using Avia and your SPL meter. If you want to set reference you need to put the volume at 0 and calibrate to (85dB for Avia right? I forget precisely. Either 75 or 85, it tells you) for each channel.

    The crossover adjustment depends on your subwoofer, and the bass capabilities of your speakers. That would take some more advanced measurements to get that really perfect, I would use a standard crossover somewhere around 80-100 hz, i dunno what the different ones are on the Sony. MY receiver just has a fixed x-over so it's not an issue.

    You also need to measure the distance to each speaker, and enter that into that menu, which sets the delay for each channel.

    Also, do a search here, and I beleive also on the Beginner's FAQ, there are some explanations on Avia and SPL calibration.

    If you're still confused, go ahead and ask more questions.

    I setup my friend's 3ES, and adjusted the x-over to each set of speakers relative to what they were capable of, ie; his surrounds are only capable of 80Hz, so I gave them a high x-over, while his mains are floorstanders with decent low end response, so I set them small with a lower x-over (I don't remember exactly what I set them to). I don't think that is what you were asking, but Chris is correct in stating that x-over will not play a significant role in setting the SPL for your speakers.
