In measuring and setting up sound systems, no topic raises more questions (and eyebrows) than how to measure and optimize the performance of subwoofers. Whether considering how to align a subwoofer to the low frequency section of a cluster or trying to create an array of subwoofers that offers "pattern" control—figuring out which measurements will be helpful and how to effectively understand and use the measured data can be a daunting task. This live sound seminar will use real world data, measured live during the event, to explore these and other issues related to measuring and optimizing a system's low end performance.
