R&D Stories: Motion Feedback Desktop Subwoofers for Nearfield Studio Monitors

In this article, Zami Schwartzman shares his personal journey to design and perfect his own accelerometer-based motion feedback desktop subwoofers, including plate amplifiers with MFB control, crossover and voice coil thermal protection that can be matched with any low frequency MFB driver. The proof of concept demonstrated the ability to perfectly complement popular active nearfield monitors, mitigating the effects of room reflection.

Test Bench: The E180HE-44 Full-Range Subwoofer from the Dayton Audio Epique Line

In this article, Vance Dickason characterizes the E180HE-44 woofer, from the Dayton Audio Epique lineup. As with the E150HE from the same range, the E180HE-44 uses the patented Multiple Magnet Air Gap (MMAG) technology, invented by Enrique Stiles and patented by Step Technologies. The E180HE is a scaled up (7") version of the E150HE, and has a similar feature set but with a secondary magnet system comprised of six ferrite disks, which act as magnetic “diodes” pulling the flux from the main magnet into the top 7mm gap.

Fresh From the Bench: KEF KC62 Subwoofer with Uni-Core Driver Technology

Following the review of the KEF LS50 Meta speakers for audioXpress, this article offers a detailed review of the KC62 compact subwoofer, which combines KEF's force-canceling and Uni-Core technologies in a new approach to allow maximizing bass in a minimum space. Masciarotte did the listening and spoke with Jack Sharkey, Senior Technical Engineer at GP Acoustics, about this fascinating design. The subwoofer was also measured by Peterson at Warkwyn’s facility using the Klippel measurement system.

Test Bench: The 10NW76 Pro Sound High SPL 10” Driver from B&C Speakers

The driver on this Test Bench is from B&C Speakers and clearly designed for professional audio. The 10NW76 was designed for uses in line arrays, small two-way monitors, and as a subwoofer, or as a midbass driver in multiway systems. It uses a proprietary 12-spoke (six double spokes) cast-aluminum frame with a series of cooling vents that allow air to move past the voice coil and across the front side of the neodymium motor assembly. The cone assembly consists of a curvilinear waterproof coated paper cone and dust cap. This article was originally published in Voice Coil, December 2021.

Like its larger E180HE-44 brother in the Epique line, the E150HE-44 is based on the patented Multiple Magnet Air Gap (MMAG) technology invented by Enrique Stiles. The two new Dayton Audio Epique MMAG woofers were designed with direct support by Enrique as an independent transducer engineering consultant, working in conjunction with the engineering team at Dayton Audio.
