Subwoofer Low Pass Filter Question

Hello,

I am setting up my new receiver (Pioneer 1018ah-k) to my Energy Speakers (8 ohms) and Subwoofer (ESW-8). The question I have is regarding the Low Pass Filter knob on the back of the Subwoofer.

1)What should the Low Pass Filter be set to on the sub? My range is 40Hz to 150Hz.

2) It is my understanding that Phase should be kept at 0 degrees as opposed to 180 degrees. For a typical room setup is this correct?

3) I am going to set up the receiver using the MCACC system. Will this set the crossover rate for the sub and if so should I not even adjust the dial on the sub?

TIA!

Jeff

1. Set it to 150hz. If you have an input on the sub labled LFE or bypass then use it. You want the receiver to be the only crossover.
2. Set it at 0. MCACC will adjust the phase with its built in delay.
3. It will set the crossover. It always sets my front speakers to large when I run it so I go back and manually set them to small.

Robert,

Thank you for your responses. The sub does have a RCA type LFE input which I will connect to from my receiver. Will be doing so tonight, hopefully it will work out. I have the Energy C-300 tower speakers. Should I still set these as small or would they be considered large?

Thanks!

Jeff

Re: Subwoofer Low Pass Filter Question

I have a Pioneer VSX-1014 so I am familiar with the MCACC calibration system. My main speakers can play down to 35hz easily and that is why the auto calibration sets them to large. I personally like all of my bass to come from a single location so I go back and set them to small. This is what sounds good to me. You should try it both ways. If you can't tell a difference then go with the small setting. That will keep phase cancellation and distortion to a minimum by filtering the bass from the mains.

I second Robert. 99 times out of 100 the speakers are better set to small. Just let the sub do its job.
