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!

It is just plugged into a Pioneer Elite Sc-07 Receiver. I know your suggestions won't be a perfect match for my situation but I just want to be as close to a neutral setting for movie watching as possible. I would refer to the manual but there is no guidance on default settings. To be clear, this Subwoofer control panel is just a bunch of knobs in top of the Subwoofer.
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.

Best,

Erik
25Hz - 0
50Hz - 0
Phase - 180, since it is located in the back of the room
Low Pass Filter - doesn't matter since you are likely using the LFE input and it is bypassed, but I would still set as high as possible like Erik said.
High Pass Filter Out - also doesn't matter, so just set it to none.

Now run the auto setup in the receiver using the microphone as Erik suggested.

I addition to the above recommendations... on my Depth i's, there are very accurate printed control settings on the back of the removable top plate. A mini manual.

Let us know how things go.
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.

Best,


Erik
