![]() ![]() We see our dip in energy around 1 to 2 kHz again and then some increased amount after that.ĭistortion response at two different output levels is shown here: Putting everything together, we can plot a hypothetical frequency response in a simulated room: Worst offenders are floor and ceiling reflections so at least a carpet is advised. We see a dip in energy around 2 kHz due to directivity error mentioned before. The port (red) helps fill in the low-bass response.īack to our "spinorama" here is how the important reflections look in a room: There is a bump in tweeter response which seems intentional to give the speaker a bit more "zing." We can also detect the crossover frequency at near 2 kHz. We see our 700 Hz resonance there as a peak in the woofer response so we know it is coming from that. Going back to the resonance, I made near field measurements (almost at driver/port location) to see what they each are doing: The woofer is getting directional before the tweeter takes over with its much wider beam width. Overall, this is a rather flat response so response is not going to be too far from neutral.Ī sharp resonance sticks out prominently at 700 Hz which you will see later in a number of other measurements. This so called spinorama shows us just about everything we need to know about the speaker with respect to tonality and some flaws: ![]() ![]() I used over 800 measurement point which was sufficient to compute the sound field of the speaker.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 an 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 and dual scan) to subtract room reflections (so where I measure it doesn't matter). Measurements that you are about to see were performed using the Klippel Near-field Scanner (NFS). ![]() The binding posts as is typical are too close to each other and recessed in this case, making them pretty difficult to turn. The finish is fine except I saw a fine white line above the speaker: It is likely a nod to retailers putting these in showrooms trying to keep fingers away from the delicate tweeter. But I did leave the tweeter screen in place for testing. It comes with an external grill that I did not use. It costs US $245 from Amazon including free shipping. It was kindly purchased by a member new and sent to me for testing. This is a review and detailed measurements of the ELAC Debut 2.0 B6.2 bookshelf speaker. Rubinson, who as a bona fide neuroscientist and professor of medicine (emeritus) understands better than the rest of us combined how our brains work and what it means when we think we think something. The first, JA1, has the unenviable and delicate task of synthesizing the FR and distortion et al data into pithy conclusions which can be decoded by the knowledgeable while neither alerting nor dissuading readers and advertisers. There seem to be only two folks there who don't overmuch exhibit this behavior. E.g., a reader with mucho money and poco tech background, as opposed to us drive-by readers who go to the site to complain about their lack of rigor and rigor-mortis-inducing As We Zzzzzzzzzzzzzz It essays). Of course, $400 to me must be what ̶$̶1̶0̶,̶0̶0̶0̶ $25,000 is like to the average Stereophile reader who actually puts stock in their recommendations as to how to ̶p̶i̶s̶s̶ ̶a̶w̶a̶y̶ spend their RSU payouts or Wall St. So, I was thinking to myself, Oh, now I know why those folks at Stereophile get more excited as the price of equipment rises into the high bling region. So for purposes of this post they're 400 bucks!Īnyway, so the point I wanna make is that THE ELAC DEBUT 2.0 B6.2s STARTED SOUNDING A LOT BETTER TO ME ONCE I REALIZED I OWNED A PAIR OF $400 SPEAKERS, rather than a set of $150 cheapies. (Actually, checking Amazon now, they seem to be on sale for $320. Then over the past few months, like you say the price went up to $400. Shortly thereafter, the price rose to $250. I bought the ELAC B6.2's on Black Friday, 2018, for $150 for the pair. ![]()
