when is a speaker considered full range?

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?

Definitely not. Mebbe even raise it a bit.

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.

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 !
