Frequency Response

OK folks, let me back up a bit. I'm trying to get a sense of certain sets of speakers (I don't have the luxury of going and listening to a lot). My old speakers, which were floorstanders, had a range of 38hz-20khz (good, average???). So as I;m specing new speakers, I'm just trying to get an idea of a "comfort" zone in terms of range....I have seen floorstanders at the low end anywhere from 20hz-40hz, and at the top end anywhere from 20khz-100khz.....but there is usually a sweet spot that most fall into. That is the sort of thing that I'm trying to figure out. I realize it's not the best way to go, but in my situation I am buying everything "deaf" so to speak. As far as the D/B I'm finding a number of companies only give you the range, not the D/B.

I also realize that my original post wasn't the best....but I can't go back and edit it. Also to some of you, I think you need to cut a little slack. You're right I don't know as much as you about this stuff....that's why I'm here.

I think +/- 3dB is the standard way of expressing the linearity of the frequency response, and if you did not quote the deviation in your 30-30k spec, I'm going to assume it. You are doing well if your speakers are only down 3dB at 30Hz - that's very nice bass response. Mine don't go that low.

I am more enamoured by speakers that are efficient (say greater than 92db/w/m) and present an easy impedance load to the amplifier - say not under 10 Ohms.

Then again, I like low power amps.

Vapor1, actually published specs can give one a ball park idea of room interaction, of course one would need the specs of the room as well.
