My Daughter changed my Subwoofer settings!

Hello,

I have a Martin Logan Decent i Subwoofer which is a part of a 5.1 system. The Subwoofer is parked in the back right corner of the living room against 2 walls adjacent to my sitting area.

My daughter , opened up the control panel and changed all of the settings. I need help setting things back to as close to default as possible.

I wish I could post a picture of what this panel looks like but it includes the following controls: (25Hz , 50Hz , Phase , Low Pass Filter , High Pass Filter Out) and can be easily found online.

Kind Regards!

Um, depends actually on your processor.  What are you using, and how did you calibrate the sub?

Usually, with fancy shmancy HT processors, you want the subwoofer to be "out of the way" of the HT settings. For that you can find instructions in the manual.

Best,

Refer to your receiver's manual then. :) It has built in room correction, and will need to be re-calibrated.  Set the Low Pass filter to as high a Hz as you can, and let the receiver do the rest.

Phase is highly distance and crossover dependent. No reason to invert it as a default. Also, receivers may correct for distance, making a paper and pencil calculation of phase irrelevant.
