when is a speaker considered full range?

full range is typically considered to be 20Hz to 20kHz.

Full range implies that the speaker can output, under suitable conditions, the full range of human hearing. According to most audiologists, human hearing extends down to about 20Hz. Looks like your speakers extend to 40Hz, so not quite full range. Depending on the size of your room and the type of music/recordings you listen to, 40Hz may be all you need, however.

Thanks for the responses.I'm not well versed in reading specs.So if i may ask in setting my crossover for the mains in my receiver i currently have them set to 60 being they go to 40 sould i change the setting from 60 to 40?

Why don't you try the various settings and see which one sounds the best to you? You're talking about setting the point where the subwoofer takes over. Try different settings and see where the best blending is.

Definitely not. Mebbe even raise it a bit.

As frequency increases (towards 20 KHz) and decreases (towards 20 Hz) the loudness decreases. The range of a speaker is usually stated as the frequency where the loudness is decreased (rolled off) by 3 dB compared with loudness at a reference frequency of 1 KHz.

Missing from this definition is any mention of the loudness level at which the measurements are made. Many small speakers claim "full range" response (down to near 20 Hz) but this is only true at relatively low volume. My custom subwoofer system consists of three 15" drivers and three 12" drivers, and it only begins to feel like a pipe organ with all the stops out.

I have heard many speakers that where ''full range'' but never delivered the goods. There are some that do deliver of course, and I was privilidged to own such a pair, but the price was ''way, way up there'', and I just couldn't stay with them as other priorities came up.

I have also have heard (and owned) monitors and floor-standing speakers that where not even close to full range, but were magical in some part of the audio spectrum that made it worthwhile.

Audio is a land of compromise. I would choose a speaker that did not provide me with the last iota of low end if everything else is sublime, as quality, truly full-range speakers are costly - unless you have a mega-dollar budget to spend.

Just my two cent's worth !

I guess this has been summed up pretty well.I had no intenion of obtaining full range speakers as i am totally content and happy about the speakers i have.I was only trying to find out if they were full range(of course not)as i did not really know what a full range speaker consisted of.So my thanks to all who ave responded.

Full range means down to about 30 Hz. There is nothing really from a musical instrument below that - even if we can hear to 20 Hz.

Like others have pointed out - full range is WAY over-rated! Give me quality low distortion correct timbre sound flat between 80 and 12 Khz anyday over full range flat but distorted between 20 and 20 Khz.

Shadorne....I'll grant you that we can get along without 12KHz -20 KHz (oh to be young again), but for some kinds of music there is indeed signal down to, and sometimes below, 20 Hz. To get it with any kind of power you need lots and lots of big drivers. A pipe organ, for example, is felt as much as heard. However, if this lowest octave is missing in the reproduced sound it can still sound good. Untill you hear the recording on a system with extreme LF response you don't know it's missing.
