    I just got the Stryke Basszone CD the other day, but I'm not sure whether I should use the warble or the sine wave tones to chart out my frequency response. Does it matter ?

    The warble tones are good for checking the crossover frequency between mains and sub to ensure seamless SPL levels at the crossover frequency.
    The sine wave tones will show your room's actual sonic environment with the frequency peaks and nulls created by the reinforcement of room reflections (for the bass region typically

    Right, if you're trying to chart the response as it will typically be effected by the room interactions...use the sines.
    and as noted, DON'T run them loudly. Since it's just a simple response chart you're after...use a low 75-80dB level.

    Thanks, guys. I was doing it at 75-80db SPL already, because that's the level I watch movies at. Now I don't have to waste time charting both types of waves.
