![]() The Listening Window is a spatial average of the nine amplitude responses in the ☑0º vertical and ☓0º horizontal angular range. ![]() The On-axis Frequency Response (0°) is the universal starting point and in many situations it is a fair representation of the first sound to arrive at a listener’s ears. For more information, please see this link. ![]() Measurements are provided in a format in accordance with the Standard Method of Measurement for In-Home Loudspeakers (ANSI/CTA-2034-A R-2020). For a detailed explanation of how the NFS works and the science behind it, please watch the below discussion with designer Christian Bellmann: Utilizing a minimum of measurement points, a comprehensive data set is generated containing the loudspeaker’s high resolution, free field sound radiation in the near and far field. studio monitors, mobile devices) as well as far field applications (e.g. Directivity, sound power, SPL response and many more key figures are obtained for any kind of loudspeaker and audio system in near field applications (e.g. The radiated sound is determined in any desired distance and angle in the 3D space outside the scanning surface. The Near-Field-Scanner 3D (NFS) offers a fully automated acoustic measurement of direct sound radiated from the source under test. Manufacturer’s information can be found here.Īpproximate retail price for these is about $329/pair USD.ĬTA-2034 (SPINORAMA) and Accompanying DataĪll data collected using Klippel’s Near-Field Scanner. Moreso, this is information for those who prefer “just the facts” and prefer to have the data without the filler. The review on this website is a brief overview and summary of the objective performance of this speaker. If you would like to help in this regard please see the “support” section at the bottom of this review. Recognizing that in a multi-channel system the majority of sound comes through the center speaker, they have optimized sensitivity and impedance to minimize the power requirement from the AV receiver, maximizing dynamic impact from lower cost receivers.I purchased these speakers myself to review with funds from Patreon/PayPal/Affiliate Link revenue. On the Bookshelf and Center Channel, moving the bass port to the front of the cabinet means placement against walls or in bookshelves won’t compromise performance. Thick MDF cabinets with a luxurious black ash vinyl finish are larger, and internally braced for greater stiffness and strength, greatly reducing cabinet vibrations which cause unwanted coloration. The added strength allows more flexibility in design to achieve a smoother, extended low-frequency response. The revised shape of the aramid cone offers even greater stiffness and damping, far superior to polypropylene or paper. Redesigned from the ground up, they sound even more remarkable than the speakers that sparked the revolution in high-end sound. ![]() And it remains the best value in the world of affordable speakers, with sound that surpasses speakers many times the price.ĭebut “changed the game,” and now it’s changed again with the Debut 2.0 Series-proof that ELAC can’t leave well enough alone. Improving on its award-winning predecessor was no easy task, but the Debut B5.2 sets a yet higher standard, delivering performance in inverse proportion to its diminutive size.
