![]() ![]() I listen for overall balance but she seems to search for the individual strings and if she hears them, she likes that. Since she plays musical instruments, she focuses on them a lot more than I do. However, she liked the sound of some of the instruments that were brought out more by the Dayton. I forget her exact words but they were right on the money as far as what I observe with respect to shrill and distorted sound. She immediately commented on the female vocals being annoying in the Dayton. Having been biased with the measurements, I thought I drag my poor wife up for a listen without telling here anything. In sharp contrast, the Pioneer was warm, and far, far more balanced in response. Female vocals were deadly with distorted lisping galore. There is lower bass that was vibrating my desk a bit but lack of upper base made them almost absent. They stood out because there is no upper bass. The Dayton Audio B652-AIR sounded good for about 2 seconds until the piercing and distorted highs started to bother me. On the right side I had the Pioneer SP-B22-LR for comparison. I set up the measured speaker to the left of my monitor, elevated about 5 inches from the desk and tilted up and pointed toward my ear. We can readily see that some kind of cancellation has sucked out the energy from the woofer at 340 Hz (middle image). This so called spinorama shows us just about everything we need to know about the speaker with respect to tonality and some flaws:ĭark color indicates loudest signal. All measurements are reference to tweeter axis with the grill removed.ħ40 points were measured (from 20 to 20 kHz) around the speaker resulting in less than 1% error across the full frequency spectrum.Īcoustic measurements can be grouped in a way that can be perceptually analyzed to determine how good a speaker can be used. In a nutshell, the measurements show the actual sound coming out of the speaker independent of the room. Both of these factors enable testing in ordinary rooms yet results that can be more accurate than anechoic chamber. It also measures the speaker at close distance ("near-field") which sharply reduces the impact of room noise. This is a robotic measurement system that analyzes the speaker all around and is able (using advanced mathematics) to subtract room reflections. Measurements are performed using the Klippel Near-field Scanner (NFS). Always enjoyable? We shall see about that as we get into measurements and listening tests. ![]()
