O.K. I read the OP and sort of understand the principles, but I get lost on the specifics. I wonder if one of you who understands this better than I could give me some advice for my new Christmas setup.
Currently I have tired 15 year old Advent Prodegy fronts and a 10 year old Infinity 8" sub, all of which I am replacing with Polk Audio RTi8s and a Polk Audio PSW12.
I have a Yamaha RX-V750 which can control the SW output by db or test tone, plus or minus. It can also control the LFE output from 0db downwards. I have the speakers now set to "small" and the sub setting to "subwoofer only"
Now I have to keep the volume on the sub pretty low, even if I have the sub setting on the receiver to 0db as it gets boomy pretty fast--perhaps because it isn't such a good sub, perhaps because it is downfiring onto a hardwood floor, perhaps both reasons. Setting the test tones to what sounds equal to the front and center speakers is invariably too much bass in general and I have to lower it, whether or the receiver or on the sub.
Anyhow, though I realize it is up to me to determine my final settings, I am a bit confused about where I should start. I have no calubration discs. I judge everthing by what tv or dvd or hd sounds like, whether the bass sounds balanced, overpowering, or lacking.
The new sub is not downfiring, which hopefully is good. The new speakers are much larger, but does that mean I should set them to large?
1. Would setting the subs volume control to about 50% be a good place to start?
2. Should I set the new fronts to large?
3. Should I set the sub setting to "both", allowing the fronts to handled any lows they can? Or should I still keep it on "Sub only"?
4. Should I leave the LFE to 0db and presume that is correct? (all audio is transmitted to the receiver by either toslink or coax from DTV, DVD, and HD DVD) How would I know if that needs separate adjustment?
Just thought it would be nice to know I am headed in the right direction for the new stuff. Any help would be greatly appreciated. Thanks in advance.
