More than just a new product category, the UberSub is a multidisciplinary "program" to bring you-are-there infrasonic realism–both audible and feelable–to the world’s finest Private Theaters and Director Screening rooms.
As installed, the UberSub does not consume even a single square foot of theater space, as it makes use of the cavity created by the baffle wall that houses the left, center and right speakers behind the acoustically transparent video screen.
Both audible and feelable down to a staggering 3 Hz,
the UberSub isn’t just about "bass" nor is it a gimmick.

The dark red blotches near the left edge indicate strong infrasonic energy, especially between about 3Hz and 12Hz, an area well below the 20-25Hz reach of existing subwoofers.
The UberSub system cleanly and convincingly delivers all of this ground-shaking, pants-flapping range.
The UberSub Program includes:
- Two Subwoofers in one Module. The UberSub utilizes a pair of horizontally-opposed, force-cancelling long-throw 24-inch drivers capable of cleanly handling 4,000 watts of amplifier power. CNC’d in California of 6061-T6 aluminum, all UberSubs are designed to dock into engineered openings in a fortress-like custom baffle wall behind the acoustically transparent video screen.
- Measuring Room Gain in situ using a reference low-frequency source to determine how the room itself – its size, shape and construction – modifies the bass (20-100Hz) and infrasonic (<20Hz) regions, and how many UberSub modules will be required to meet the output level and distortion targets for the chosen program (Red X or Black Label).
- Using advanced, in-house finite-element (FEA) tools to model, simulate and optimize a custom Baffle Wall to create an acoustically inert, non-resonant, supportive environment for the UberSub modules and screen-channel speakers (Left, Center, Right). Without the benefit of FEA studies, which reveal where and what kind of structural bracing is needed, the sound pressure levels within the Baffle – which can exceed 130 decibels – would cause the structure to flex, distort and open up seams, creating air-leaks, rattles, resonances and other acoustic defects. The construction of the baffle wall itself is carried out by KYD’s chosen specialty contractor/partner, working from KYD’s detailed 3D construction drawings, and under KYD’s direct supervision.
- Conducting a Sleep Disturbance Study to predict the flow of deep bass and infrasonic energy out of the theater/screening room and into bedrooms and other noise-sensitive spaces. Based on industrial-type acoustic modeling tools, the study can predict whether, when you’re screening an action spectacular like War of the Worlds, the decibel values in sleeping rooms elsewhere in the home will likely rise above the sleep disturbance threshold. If it does, we model the effects of different sound-control strategies in the theater’s walls, floor, ceiling, doors, etc. to find the most effective solution.
- Running BassCAMP to acoustically model, and mathematically rank hundreds of thousands of unique subwoofer layouts in the room to reveal the top performing combination of subwoofer quantity, locations and settings (gain, polarity and delay) to cover the 20-80Hz range with the lowest seat-to-seat variation. At its core, KYD’s BassCAMP is a custom, brute-force, CFD-based, in-house designed simulation and optimization platform that finally solves the seat-to-seat bass variation problem in real-world home theaters, which typically reach 30, 40, even 50 decibels, a disparity that is far beyond any equalizer to manage. With BassCAMP’s ability to find the optimum subwoofer layout, the same room’s worst-case variation is typically reduced by 20, 30 or even 40 decibels. With judicious acoustic treatment selections and a little touch-up in signal processing during final calibration, every seat can become a “money seat” where bass is consistently deep, crisp, and physical.
- On-Site Testing and Commissioning, including fine-tuning the transition between the UberSubs and the “full-range” system to be aurally seamless; and
- Issuing a Report on the general physics and auditory perception of the low-frequency and infrasonic ranges, including detailed before-and-after measurements.
Born from 30 years of real engineering, KYD delivers
the most immersive cinema experience. Period.
Most of the sounds you hear in a movie are recorded in a building called a Foley stage with microphones that capture sonic energy down to 2 or 3Hz. As the many textbooks on human hearing state, sounds below 20Hz, i.e. the infrasonic range, can be heard, provided they’re reproduced at a sufficiently high sound pressure level.
The problem is that even the most ambitious consumer or professional subwoofers have not been able to reproduce the full range of infrasonic energy at high enough levels to rise above the hearing threshold. This has long been an issue. The manufacturer of an expensive, coat closet-size subwoofer offers a graph showing response down to 18, 16, or even 14 Hz, but doesn’t disclose that at those frequencies even its maximum output is below the threshold of human hearing, i.e., inaudible. Commercial cinemas fall further short as they typically cannot generate useful response below 30-35Hz.
