Right been reading a few of the threads on Sub Woofers and the crossover / filter points for them and have realised that I do not fully understand things . There are some on here who use Subs and seem very informed so as the only stupid quaestion is the one you do not ask here goes.
In my three way active system which is two pairs of KEF 103 Reference 70,s speakers per side . The top speakrr has the Bass/Mid and Treble unit active with the Bass unit acting from 290hz - 3000kHz when the Treble takes over . Now the bottom unit on each side only has the Bass/Mid driver connected and this is set from 20Hz - 290 Hz thus doing the low bass work of the system similar but i realise now not the same as a Sub . Now in my case I tried 48db CR points for the low bass starting at 250Hz and then increasing it by small increments and listening until I settled on the 290Hz as being the best compromise . Now in the Sub threads the CR point is given as being around 70Hz so as to not interfere with the main speaker .
So is what i am using just a three way active and this accounts for why the CR points are very different and sound best (to me at least) at the points i have set . Or should I be looking to have like a sub the low bass unit set to a much lower level ?
While this may seem obvious and have its answer in the different way that Subs work it is not obvious to me and would appreciate a little helpful education .
