Trinnov Audio used CEDIA Expo 2026 in Denver to announce a substantial rework of WaveForming, its active bass technology, and the headline is about who can now use it. The company says the updated capability rolls out to the entire Altitude processor range as a free software update by the close of the show, which ran September 1–4 at the Colorado Convention Center.
Until now, WaveForming has been a technology for ambitious rooms. It works by using multiple subwoofers as a coordinated array — front subs generating the wanted bass, rear subs cancelling the reflection that would otherwise bounce back off the far wall and turn into a room mode. That is a genuinely different approach from ordinary EQ, but it has historically meant four or more subwoofers and a dedicated room, which put it out of reach for most installations. At Expo, Trinnov demonstrated the reworked version driving a stereo playback system with only two front subwoofers, in HPA Meeting Room 204.
Trinnov also says existing WaveForming users get improved performance from the update without recalibrating their systems, which is an unusual promise for a technology whose whole premise is a measured model of the room. Alongside the bass news, the company showed an updated Altitude software build and demonstrated plain-language voice commands for adjusting playback in real time as a look at where it thinks AI fits into custom installation. Trinnov systems were also running WaveForming on partner stands, including Krix in Sound Room 5 and Alcons in Sound Room 9.
Why it matters for tuning: low bass is the one part of a room you cannot really EQ your way out of. Below roughly 100 Hz the room's dimensions decide where the peaks and nulls land, and a null is a cancellation — adding gain there just burns amplifier headroom without raising the level. Multi-sub approaches like WaveForming work because they change the sound field itself rather than the signal feeding it, which is why they can do things a single-channel filter cannot. If the reworked version really does deliver useful results with two subs at the front of the room, that moves it from a showcase feature into something an ordinary two-sub system might actually run. Either way, the honest test is the same: measure at the seats before and after, look at what happened to the nulls, not just the peaks, and check whether the improvement holds across more than one seat.
Trinnov had not published detailed technical documentation on the reworked algorithm at the time of the announcement, and the two-subwoofer demonstrations at Expo were stereo rather than full immersive playback. We'll follow up with measurements if we can get time on an updated Altitude in a normal-sized room.
