    Hi All,

    I'm in the market for a receiver (low end) and am wanting my system to be as good as possible. I have a little information concerning the bass management of various receivers, but not nearly enough to determine the exact nature of the crossover frequencies and alignments.

    Has anyone actually measured their receivers to find out what is going on? There are a number of different setups that need testing, ie. Speakers set to small/large, the various input formats (2ch analog, digital 5.1, analog 5.1 etc.)

    I am planning to test a few receivers if the store will let me and am basically wanting to get the procedures etc. sorted out so that it is best done.

    Any info regarding the following receivers is especially wanted:

    Yamaha RS-V430,530 and 630
    Denon 1802, 1603, 1803
    Onkyo 494, 595 etc.

    All the Yamaha receivers have a 90 Hz crossover. I believe the subwoofer slopes at 18dB/octave and the mains drop at 12 dB/octave. Denons have the same respective slopes, but crossover at 80 Hz. Onkyo 595 crosses over at 80 Hz. The 494 crosses the mains at 120 Hz (6 dB/octave) when set to SMALL, or at 80 Hz (12 dB/octave) when set to LARGE. There is no full-range setting for the mains, which is smart since most 494 owners won't be using full-range towers. I don't know if the sub stays at 80 Hz, but my guess is that it stays at 80 Hz regardless of LARGE or SMALL setting.
