The new Theatrus T83S On-Wall Speaker joins a growing line of slim on-wall monitor speaker options from our highly acclaimed Theatrus Cinema Studio line. Designed and perfected for custom installation, these slim cabinets offer an unobtrusive solution for massive sound staging. Every Theatrus speaker is loaded with our latest crossover and driver technologies, housed in our stealth black cabinetry, and includes our stealth mounting bracket that makes installation a breeze.
The Theatrus T83S On-Wall Speaker is a 3-Way design, featuring an array of three (3) drivers, which fuses into a super force of sound quality that is designed for home theater or custom installation, professional music studios, and film studios. It's not all about sound though, the speaker has a clean and smooth appearance. The Aperion crafted AMT Haier Ribbon Tweeter, and 2-inch Soft-Dome Mid-Range Drivers are housed in a custom designed aluminum faceplate.
Enhanced low end is produced by a single 8" Woofer which was crafted from Germany's Propex Fabrics' Curv material. The Theatrus T83S On-Wall Speaker offers higher sound pressure levels, suitable for small to large listening environments.
The Theatrus T83S' High-Efficiency plus High-Power makes for an explosively wide sound field.

Product Features
HiFi Level Sound Quality
The Theatrus Speaker is known for four key strengths: high sound pressure levels, excellent power handling, remarkable dynamics, and low distortion. It delivers both powerful cinematic impacts and subtle sonic details with clarity. The T83S features one independent soft-dome midrange drivers and is finely tuned for high-frequency sensitivity, delivering a transparent, rich sound without harshness. This results in a natural listening experience, making dialogue and music feel authentic and emotionally engaging.
A Powerful Lineup
The Theatrus series is an ideal choice for custom-installed home theaters, offering a robust lineup that balances acoustic performance, aesthetic design, and spatial adaptability. These products are highly acclaimed in the U.S. and globally recognized for their exceptional quality, delivering a superior cinematic experience. Choosing Theatrus means choosing professionalism and trust— a decision you'll never regret.
Three Way Design
The Theatrus T83S features a superior three-way speaker design, demonstrating significant advantages in audio reproduction. It is meticulously configured with Aperion’s Air Motion Tweeter, boasting exceptional sensitivity and the ability to precisely reproduce high-frequency details; one 2-inch soft-dome midrange driver, delivering rich, natural midrange performance; and one 8-inch long-throw Curv Cone woofer, providing a powerful, highly impactful low-frequency soundstage.
Sealed Slim Cabinet Design
Slim on-wall and in-baffle loudspeakers often face significant design constraints, making enclosure integrity especially critical. By utilizing a fully sealed enclosure, Theatrus On-Wall loudspeakers eliminate unwanted interactions between the rear wave of the driver and surrounding structures, preserving accuracy and consistency across installations. This controlled acoustic loading enhances transient response, improves tonal balance, and delivers tighter, more articulate bass performance. The result is a loudspeaker that combines a sleek, space-efficient profile with the clarity, precision, and dynamic impact expected from true high-performance audio.
Robust Construction
The T83S features a cabinet constructed from robust, high-density fiberboard (HDF). Its interior is meticulously engineered with multiple structural braces to ensure rock-solid stability, effectively eliminating cabinet resonance at its source and enabling a pure, interference-free audio output. The cabinet is finished with a matte black paint that feels premium to the touch. It's especially well-suited to a dark cinema environment because it is non-reflective.
Easy to Mount and Install
The Theatrus T83S speaker features four mounting holes on its back, allowing for flexible installation in various orientations. Included in the box is our Stealth Wall Mount, making installation quick and easy. Additionally, two rubber feet are included in the package. Please note that you need to attach these rubber feet near the red circles shown in the picture above to ensure the speaker remains balanced.
Seamless Integration
Meticulously designed and repeatedly fine-tuned by our dedicated team of engineers, the Theatrus T83S was crafted with full consideration for compatibility with other Theatrus models. It combines aesthetic design and acoustic characteristics to ensure seamless integration, creating a harmonious, unified, and deeply immersive listening experience for you.
Quality Commitment
Theatrus offers a five-year warranty and lifetime maintenance and support, showing our commitment to quality and customer satisfaction.
Aperion's AMT (Air Motion Transformer) Tweeter
The APERION AMT tweeter features a sensitivity of up to 103 dB and a frequency response extending to 40 kHz, allowing for efficient sound conversion and a wide sound range.
Utilizing AMT technology, it delivers high-fidelity sound without compression, ideal for high-quality audio enthusiasts. The tweeter produces vibrant high-frequency sounds.
Its excellent diffusion expands the listening range, making it excellent for large and medium-sized home theater rooms. While still shining bright in smaller dedicated rooms.
Proprietary 2" Soft-dome mid-range driver
Our high end soft-dome midrange unit features a large, low distortion 50mm voice coil, which exceeds the normal size of this type of drive unit.
Its wide pole structure and proprietary dampening coating work in harmony to diminish medium frequency segmentation vibrations significantly.
This style of midrange driver is commonly used in high-end monitors and audiophile speakers and is renowned for its unique design and exceptional sound quality.
It provides excellent off-axis response and low distortion, delivering a warm, whole midrange tone. Additionally, it enhances sound diffusion and directivity, ensuring even distribution and reducing standing waves and reflections for a more natural listening experience.
The sonic attributes enhance both the AMT and CURV drivers, providing impressive detail and clarity.
Single High-Excursion 8" CURV Woofer
The Theatrus Series introduced a cutting-edge CURV material from Germany's Propex Fabrics for each of its Woofers.
This new material is delightfully lightweight while also being rigid and stiff.
It maintains a high resistance to temperature without absorbing water, and, most importantly for driver unit creation, it possesses a high Young's Modulus along with internal damping.
Advanced Crossover
Time-intensive iterative designing and fine-tuning of the crossover networks have resulted in a smoother, more neutral, and better-balanced frequency response across the whole range. Enhanced phase integration between the tweeter and woofer drivers has also resulted in a cleaner, more open sound in the transition regions.
All of the speakers in our Theatrus series are meticulously crafted with high-quality custom components, including Aperion's premium metallized polypropylene capacitors, copper wire inductors, and precision wirewound resistors.
These components come together to create an audio experience that is both beautiful and enjoyable.
In our relentless quest for excellence, we’ve even adorned the PCB in Aperion's signature red, a testament to our unwavering commitment to delivering exceptional sound quality!
Sound Adjustment
The Theatrus T83S Speaker adapts to various arrangements and positions with adjustments for Free-Field or Acoustic Screen. It included a high-frequency adjustment to compensate for the high frequency when the speaker is placed behind a projection screen.
How to adjust the sound
Sound Adjustment Jumper
On the aluminum backplate housing the crossover controls on the rear of the T83S, there is one jumper plug for adjusting the high-frequency response.
High Frequency Adjustment
If the T83S needs to be positioned behind a projection screen—which attenuates high frequencies—you can insert the high-frequency adjustment jumper into the "Acoustic Screen" position to boost high-frequency sensitivity to compensate for the attenuation.
Rotatable Easy-Pull Spring-Loaded Logo
The Theatrus T83S speaker can be placed nearly anywhere; On-wall, In-wall, on the ground, on a stand or even on the ceiling*, the Theatrus line can effectively cover most of the listening area. The speaker can be arranged vertically or horizontally, dependent on the application.
*While we do not recommend you mount the Theatrus T83S to the ceiling yourself, should you mount the Theatrus T83S speaker on the ceiling take precautions and ensure you mount it to a ceiling joist, and are using appropriate mounting hardware.
Rubber Bumper Feet Installation
There are two rubber bumper pads included with adhesive on one side. These rubber pads are to be installed to prevent the speaker cabinet from vibrating on the surface on which it is placed. It will also prevent vibrations while hanging on the wall. Lastly, the rubber pads also prevent the speaker's surface from getting scratched.

High-Fidelity Cinema Sound Quality
While listening to music, the high-frequency performance stands out, with a solid low-end density and a wealth of detail in the mid and high frequencies. The low frequencies are quick and distinct, showcasing impressive layering.
In a multi-channel home theater setup, the audio imaging characteristics of the system are clearly evident. The sound field positioning is exceptionally precise.
Its transient response and control are excellent, allowing for smooth transitions between large and small signals.
The sound retraction and release are sharp and crisp, with no dragging, perfectly complementing the original soundtrack and delivering a genuine audio experience to the audience.
The independent dome midrange and AMT tweeter produce vibrant sound, yet they manage to remain soft and avoid being overly harsh.
Even from outside the home theater, the sound quality is easily discernible. For example, when listening to opera, the sound demonstrates powerful penetration, effortlessly passing through sound-transparent curtains without any strain!
Custom tuned 1" Thick HDF Cabinet
Theatrus drivers come packed in a Stealth Black 1" Thick HDF Anti Resonant Cabinet.
This stealth black finish is a master at avoiding light reflection, making it the ultimate choice for your private cinema.
For a powerful home theater performance, a sturdy cabinet is essential. Every Theatrus speaker is made from tough and premium 1" HDF and is designed to keep cabinet vibrations at bay.
It’s also built to last, showcasing impressive durability. And let’s not forget, it resists fingerprints and is easy to clean and maintain.
Sound Adjustment
A jumper switch is located on the rear of the loudspeaker and is factory-preset to "Free Field" mode. Perforated projection screens typically attenuate high frequencies, whereas woven screens generally do not; however, this is merely a general guideline, as performance varies significantly across different brands and screen types. Consequently, we have provided an "Acoustic Screen" option that boosts high-frequency output by +5dB to compensate for the high-frequency attenuation caused by acoustically transparent screens or fabrics. You should select either the "Free Field" or "Acoustic Screen" setting based on your actual listening preference.
5-Way gold-plated binding posts
The 5-way gold-plated binding posts let you connect your speakers any which way you choose: bare wire, banana plugs, spades, round pins or flat pins.
Easy to mount and install
The Theatrus T83S speakers features multiple mounting holes hidden by threaded inserts on the back of the speaker.
Also included in the packaging you will find one of our Stealth Mount Wall Bracket, making installation quick and easy.
Sealed slim cabinet design
One of the key steps to achieving exceptional sound quality is precisely controlling the sound emitted by the loudspeakers—confining it to the interior space rather than allowing it to scatter chaotically across the walls, which would generate unnecessary reflections and interference. For this very reason, Theatrus wall-mounted loudspeakers feature a sealed enclosure design; this fundamentally prevents sound leakage, ensuring that every ounce of energy is concentrated within the listening environment to deliver a purer, more precise sonic performance.
Rotatable Easy-Pull Spring-Loaded Logo
Theatrus speakers can be placed On-wall, In-wall, on the ground or on the ceiling, the Theatrus line can effectively cover most of the listening area. The speaker can be arranged vertically or horizontally, dependent on the application.
Lightweight magnetic grille
To protect the speaker's drivers from accidents, pets or curious fingers, the entire Theatrus line sports a lightweight magnetic grille which can easily be removed when you want to show off your beautiful speakers to friends and family.

Five (5) year warranty on cabinets, crossovers, and drivers, with lifetime customer support.
