What do you all think of this scale:
For every decrease in a Star, the range of the score widens by 25%. No real science here for the ranges...the thought was that as you obtain more subwoofage per cubic foot of your room, the more room gain you will have (e.g. a smaller room with 2 subs will have more gain than a larger room with the same 2 subs).
Additionally, the star rating can be thought of as the amount of output you have for your size room, at the lowest frequency you care about. Some folks don't notice the very bottom octaves...could be their room, could be their furniture doesn't 'shake' at those frequencies, it could be you just can't tell a difference. Whatever the reason, it's all about your ULF perspective. You can choose what frequency you wish to measure your system at, and it will be equally weighted.
This rating doesn't care about extension, but more about clean output at the lowest frequency you care about.
My assumption is that clean output at the max levels you would listen at trump extension where you can't get to the max levels you want. In other words, a system that is high passed at 16hz but can reach clean reference output at that level, will trump a system that extends to 10hz, but has noticeable THD at 16hz to 10hz at reference; and can't get to your max levels. Said another way: clean output rules over extension that you can't cleanly get at the levels you want.

Let's keep things in perspective here as well. Most HT systems don't even get a star!!!! To be in the 1.5 star range, putting things in perspective, your HT experience still is very adequate and perhaps even too much for the general population!!! However, this is AVS.................
Let me know what you guys think. Does this scale 'feel' right based on how the different HT systems have scored above?
