If a sub is connected via speaker level connections, does the receivers internal amp still power the mains, or is the sub's amp now powering the mains? Just curious. |

Yes because its acting like low pass filter where it cuts off some of the lower end of the frequency response.
You would still need to set the volume to the correct tone of the crossover point at the subwoofer.
Its best used with separate individual inputs going to the sub rather than as whole, this will allow you to experiment.

If your receiver has no sub-out, then the only option is to use speaker level connections, like I do.
The XO in the sub will taper the low level cutoff, but the mains will still see the full spectrum.
If your mains do not like the full bass, of if you want to tailor things a bit, then a cub with mains in and out will let you tailor the response that the mains will see.
However, the bass will sometims roll-off a full octave, muddiying things up a bit.
A good sub can filter this, if it has a 4th order filter.
Always look for 4th order or higher in a sub for a sharp roll-off. |
