Ascendo Unveils HALO 10 Pro Active EXT Cardioid Speaker at CEDIA Expo 2025

The new HALO 10 Pro Active EXT Cardiod from Ascendo Immersive Audio is a three-way active speaker with a peculiar circular configuration. As Ascendo explains, unlike conventional speakers that radiate sound omnidirectionally, often causing unwanted reflections and bass buildup, the HALO 10 directs low-frequency energy forward, minimizing rear-wall interactions. In the middle, there’s a 10” midrange driver (operating from 200Hz up) paired coaxially with a 3” compression driver, surrounded by six 8” woofers in a cardioid array.

This article reviews a patent awarded to Paul Wayne Peace Jr. and Derrick Rodgers, on behalf of Harman International Industries. The patent describes a surface-mounted loudspeaker design that mitigates the interference between direct low-frequency (LF) energy and reflected LF energy by breaking the LF energy from an LF driver into multiple paths using one or more of waveguides, driver load plates, and enclosure ports to diffuse the reflected energy and minimize frequency response errors.

Celestion is expanding its range of professional audio drivers for sound reinforcement applications with the debut of the 18-inch PowerProX18 subwoofer. The new model features advanced voice coil cooling to boost reliability and reduce power compression, enabling high performance over extended periods of peak delivery, as required in applications including cinema sound, fixed install and touring sound reinforcement. The new PowerProX18 will be on display at NAMM 2023, alongside a range of new key PA products from Celestion.

Ascendo Immersive Audio has introduced four versions of its much-anticipated CCRM15 speaker system, now available in passive and powered active models and with Titanium or Beryllium drivers. The 15" point-source axi-symmetric speaker has been designed as a screen channel for large theaters as left, center and right channels or can be used for very large theaters as a surround bed speaker. The CCRM15 Beryllium is now the top performing coaxial model from Ascendo.
