    I have noticed that most AVR manufacturers recommend setting all speakers to (small) and the freq to 80hz. Then set the LFE to 120hz. This is for HT and I believe it is a THX recommendation that they are following.

    For music, whether in 2 ch or 5.1, you are just going to have to mess around with it to see what sounds best for you.

    Hope this helps and good luck :)

    I am very new to the non-HTIB world and am curious if someone could explain how and what crossover does? Thanks!

    Modified Crutchfield explanation.


    Q: What is a crossover?

    A: For the most complete answer to this question, you'll want to check out our crossover article. In simple terms, a crossover is like a traffic cop for audio frequencies. It filters and directs frequencies to allow only a certain range of frequencies to reach a certain speaker. Frequencies outside that range are attenuated or blocked.

    A high-pass filter allows only frequencies above a given point to pass through. A low-pass filter allows only frequencies lower than a given point to pass through.
    In a hypothetical audio system the audio frequencies might be directed as follows:

    Low frequencies (say 100 Hz and lower) go to subwoofers.
    Midbass speakers get frequencies between 100 and 250 Hz.
    Midrange speakers would see frequencies between 250 and 3,000 Hz.
    All frequencies above 3,000 are handled by the tweeters.

    The best crossover points for one speaker might not be the best for another. It all depends on the useful range of the speaker. Most electronic crossovers allow you to choose from several crossover points.

    Basically all the crossover (you will see xover a lot on this board) does in the home theater application is determine how low of a freqency will be set to your speakers. The higher the xover setting, the less low your speakers will go. Much is expected from the sub in HT. Frequences below what is set on your receiver will be sent to the sub via the LFE channel.

    No matter what the manufacturer recommends, or anyone here recommends for that matter, it is always a good idea to "play" around with your system and decide what sounds best for you.
