Re: Stand alone 215 cabinets question.




Craig,


Without measuring its output, it's not possible to know what the desired filter result from the Yamaha DSP. Even with another DSP, these kinds of settings are difficult to match as the numbers you put in on one may not create the same output on another. With a graphic EQ, however, it may not even be possible to create the desired filter shapes. The filter frequencies are arbitrary (as far as your loudspeaker is concerned), you will have to use several in combination, and their effects in combination are totally unpredictable. Graphic EQs are good for many things, quickly EQing to taste or quickly killing feedback for instance. Compared to the filters in a DSP though it's like trying to kill a fly with a cannon, only you can't even move the cannon horizontally, only vertically, and you can't see where you're shooting.


I'm not saying you can't use a graphic EQ to improve the sound of your monitor, but trying to copy these settings into one is going to be very frustrating. The Q of a slider on a 31 band graphic EQ is, ballpark, 4. How do you make a Q=6.3 filter at 137Hz, -4.7dB?
