I don't think I'm any "smarter" or more intelligent than other posters on this forum. However, I do believe that I have some experience with measurements and their interpretation that could be helpful to a lot of other forum members. For that reason, I think I can offer some valuable insights into the benefits of using these measurements to optimize a speaker/subwoofer(s) system.
Over the course of my participation on AVS, I have come to the realization that the human ear is a very inaccurate measurement device. It hears what it wants to hear, and pre-hearing biases can overwhelm the true listening experience. The only true, unbiased listening experience is the one done by an unbiased microphone. Moreover, I have found that, if one can get the microphone-based measurements optimized, the sound quality *always* follows, often in amazing and "magical" ways.
For example, I once visited a guys home to hear his system. It was a multi-6-figure system, ($300,000+) with hugely expensive, "high end" speakers, expensive monoblock amps on isolation stands, with speaker cable "lifts", outbaord DAC's, uber-expensive power cords, power conditioners, interconnects and speaker cables... blah, blah. blah... all the "high-end" audio-foolery one could imagine. The subwoofer system was 2 very highly regarded 18" drivers in sealed cabinets. I listened to 2 musical cuts I was very familiar with, and I immediately said,
"Wait... I need some measurements because some thing doesn't sound right." I was hearing some notes way too loud an other were completely missing.
Here is the first measurement I took:
This measurement confirmed exactly what I was hearing. Some notes where highly over-accentuated, (the 40 - 50 Hz range), while other were virtually inaudible, the 65 - 100 Hz range.) I then proceeded to make some adjustments. I then re-ran Audyssey and optimized the subwoofer Distance settings. These were the FR's I ended up with:
The top trace is the response at the primary LP, while the bottom trace is the response averaged over the 3 front seats.
The difference in SOUND QUALITY was literally *incomparable*!!! The boomy, one-note nature was gone. Every note became articulate and precise. The absolute power and deep, authoritative extension came to life. All the performance the guy had paid for, (in spades), was now realized.
The bottom line... You can spend mega-$$$ for performance of any one single component of an audio system. However, if you don't optimize that performance, you'll never realize the benefits of your expenditure. Measurements are the *ONLY way to know if you've optimized the performance of the component you've spent multiple thousands of dollars to acquire.
Bottom line... You can lead a horse to water...
