Trulli Audio Introduces Bass50, World’s First Battery-Powered Thin Subwoofer

Trulli Audio is now shipping its wireless, battery-powered Trulli Bass50 subwoofer, delivering high-output bass in a plug-and-play audio solution. A truly revolutionary concept based on the company's ThinDriver technology, the project is a multi-year development effort that saw Trulli also creating dedicated manufacturing facilities in its Mundelein, IL headquarters. The Bass50 subwoofer meets a variety of applications, from mobile DJs, as a subwoofer to other Skaa-enabled wireless speakers, and even for car and marine audio.

In this month’s Voice Coil Focus, Mike Klasco writes about Innovative Speaker Drivers, and there is an updated Microspeaker Vendor Directory for 2022, with additional subdirectories on MEMS speaker transducers and Haptic Actuator devices for mobile devices. On this month’s Test Bench, Vance Dickason characterizes two full-range woofers: the E180HE-44 from the Dayton Audio Epique home audio line-up, and the Faital Pro 2FE24 2.5” small woofer targeting pro audio applications.

Trulli Audio confirmed the official availability of its JAM5, the first in a line of portable speakers powered by Trulli's patented, ThinDriver technology. Initially unveiled as a proof-of concept, the JAM5 was recently offered direct-to-consumer on the company's website, receiving great reviews. Using an interesting configuration with two TD38S ThinDriver units combined with two opposite passive radiators and a center tweeter, this speaker impresses for its low bass extension. It can be also paired for stereo, for even more impressive results.

In Voice Coil September 2021, Vance Dickason writes about DSP crossovers from Danville Signal, Joe Hayes (Vastigo) writes about the DaS AuReality patented 3D loudspeaker technology, and Mike Klasco finds speaker-related technologies that help support smart speaker design efforts. This edition's Test Bench characterizes three new 25mm high-frequency tweeters from BlieSMa, using silk, beryllium, and diamond domes: BlieSMa’s T25S-6, T25B-6, and T25D-6.

audioXpress September 2021 celebrates its Speaker Builder magazine origins, once again offering an expanded focus on loudspeaker building, design, and testing. Mike Klasco provides an update on Speaker Technology, Claus Futtrup and Jeff Candy discuss Parameter Estimation and Box Simulation with Speakerbench, and Geoff Hill tells us the Tetrahedral Test Chamber Story. In this edition we pay tribute to Roger Russell (1935-2021) and we feature two great DIY projects. Now available online and in print.
