My sub comes with a remote where you can set the phase. What does it exaclty do? It goes from 0,90,180, and 270. My sub is in a corner (is that recommened) and about 5 feet away. do I leave it at 0.

What do I put the high pass crossover on 80hz or 100hz?

Short Answer: keep it at 0 degrees and set the high pass at 80hz.

Long Answer:
The phase control is basically to help your subwoofer blend better with your main speakers. Try experimenting with the different phase degrees, if there are no audible improvements then keep it at 0. As a speaker makes sound, it travels back and forth. Adjusting phase on a sub allows it to move back and forth similar to your mains therefore allowing it to integrate more smoothly. It depends on where you put it and the the acoustics of the room. You'll be able to tell what would sound better if you try the different settings though.

Most people keep the pass at 80hz. It depends on what kind of speakers you have. Since you have that sub, I'm guessing you have some pretty nice speakers also. If your speakers can produce some of the lower frequencies (ex. <40 to 80hz), then keep it at 80 or maybe lower if you can. If they cannot, go for 100hz. For example, the speakers I built can reach down to 80hz, but can't really go any lower without hurting themselves. So I had to set the crossover around 90. That way, the speakers would stop around 90hz and then my subs would take over from 90hz and lower. The bad thing is that when you go for a higher pass like 120hz or something, then it will be easy to localize where the bass is coming from. You want the bass to encompass you, not just get you from one side.

So, you are saying that when dealing with the crossover on the subwoofer, lower Hz is better?

To a point. some where in the 70-100 range. Too low and you'll be asking too much from you main speakers(or wont be gettting much in the way of bass) and too high, you'll start to "notice" the sub as tabasc07 described.

Sabian576 I think you meant to say like what I said but okay haha.

To Petra: a lower pass, isn't, per se, better. It really depends on your mains. Just like what Sabian said, if it's too low, then you'll be pushing you main speakers too much. You really have to find the median on which your sub and speaker blend with each other fairly well. Too high, you'll be able to tell where it's coming from. Too low, your speakers will hate you.

Not with your speakers, i would set yours at 100hz and see how that works, the m-1 are only only rated down to 80 hz and are not very efficient so they are a tough load to drive, move as much low end to the sub as you can, it will help your receiver.

Read the thread on "A Guide to Subwoofers". It has a section on crossover frequency and a section on phase adjustments. Remember that crossovers frequencies are not precice cutoff points. They are more like frequency roll-off points.
