Adding subwoofer to Full-Ragne Speakers question

Let's not anthropomorphize speaker drivers. They do not have powers of concentration. They merely move in response to electrical signals delivered to them. Now I suppose it's conceivable that if a crossover were diverting LF signals away from your mains, the drivers might be marginally more accurate, at least at times. But I wouldn't expect this to be particularly significant, if it's even real. And any such effect will be overwhelmed by the effect on the bass. When you try out a subwoofer in your system, I guarantee that your decision about whether you like it or not will turn on bass performance, period.

The sub will only help the front speakers at and below the crossover point you set. Most will set it at 60-80hz. You need to know the low cut-off HZ level for the speakers and then see what either the pre-amp/receiver and sub x-over will allow you to set for the cross over. If you have speakers the drop down to e.g. 35Hz and the sub will let you set your X-over point as low as 40hz the try it there for starters. As far as the Mid Range it remainst the same. The speakers never know the sub is playing so they offer no compensation for range. If your reciever/pre-pro let you set the cross over then the front speakers will never see the frequencys below the cross over point as that information is re-routed to the subwoofer.

Well, thanks guy...

Theo says it's not goinig to help at all.

Bomarc basically says it might be marginally helpful but probably not that significant

I don't know how speakers work internally, but basically what I thought was that producing bass is a lot of work for the speakers, and if the subwoofer take some of the hard work away, then there would be more capacity left with the mains to work on other area(namly midrange), thus produce more accurate and rich midrange sound.

I guesss it does not quiet work that way??
