Theatrus T80WL In-Wall LCR Speaker
The Theatrus T80WL Speaker is a 3-Way LCR In-Wall Speaker featuring an array of five (5) drivers that fuse into a superforce of sound quality, designed for home theater, 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 Ribbon Tweeter and Dual 2-inch Soft-Dome Mid-Range Drivers are housed in a custom-designed aluminum faceplate. Enhanced low end is produced by Dual 8" Woofers, which were crafted from German Propex Fabrics Curv material.
Authentic Cinema Sound At Home
When Aperion Audio began developing the Theatrus series in 2021, we focused on a key challenge: how to create thinner, more compact speakers while maintaining excellent sound quality. Our goal was to make the Theatrus speakers versatile for various applications and to enhance their ability to blend seamlessly into different environments. Our primary objective was to engineer slimmer speakers capable of delivering exceptional sound quality. Additionally, we emphasized the importance of aesthetic appeal, ensuring that the Theatrus T80WL In-Wall Speaker could effectively blend into their surroundings for improved concealment.
The decoration style of private custom home theaters is increasingly focused on creating an unobtrusive and streamlined environment. Designers prioritize the concealment of external devices, such as speakers, projectors, and wiring, to achieve a clean and sophisticated aesthetic. This trend enhances the home theater's visual appeal and maximizes usable space, contributing to a more immersive viewing experience. By integrating technology seamlessly into the design, homeowners can enjoy a captivating atmosphere without the distraction of bulky equipment. This approach emphasizes simplicity, elegance, and functionality in home theater spaces.
Since the launch of the Theatrus T80WL In-Wall Speaker model, these speakers can blend into your home theater, making them almost invisible. They provide fantastic movie sound without any distractions. This long, rectangular cabinet accommodates placement between standard 16" stud spacing.
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 T80WL features two 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 T80WL 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; two 2-inch soft-dome midrange drivers, delivering rich, natural midrange performance; and two 8-inch long-throw Curv Cone woofers, providing a powerful, highly impactful low-frequency soundstage.

Sealed slim cabinet design
One of the most important factors in achieving exceptional sound quality is controlling how the loudspeaker's energy is used. A sealed in-wall speaker enclosure prevents sound from dispersing into the wall cavity, where it can create unwanted reflections, resonances, and performance inconsistencies. That is why Theatrus in-wall loudspeakers feature a fully sealed enclosure design. By isolating the driver from the surrounding wall space, they deliver more accurate bass response, greater tonal consistency, and improved clarity, while also minimizing sound leakage into adjacent rooms. The result is a cleaner, more precise, and more immersive listening experience.

Robust Construction
The T80WL 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.

Seamless Integration
Meticulously designed and repeatedly fine-tuned by our dedicated team of engineers, the Theatrus T80WL 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.

Theatrus T80WL is truly the perfect in-wall LCR Speaker
We are delighted to introduce the new "Slim Stack In-Wall" series of Theatrus speakers. These speakers seamlessly blend into your home theater, making them almost invisible.
They provide fantastic sound without any distractions. This long, rectangular cabinet accommodates placement between standard 16" stud spacing.
The T80WL is ideal for center channel use, but work excellent as front left and right as well as surround, but can be used in any position in the home theater system for a detailed and immersive sound stage.

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.

Dual 2" Soft-Dome Midrange Drivers
Aperion's 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.

Dual High-Excursion 8" CURV Woofers
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 wire wound resistors.
These components come together to create an audio experience that is accurate, impactful and exhilarating.
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 T80WL Speaker adapts to various arrangements and positions with adjustments for Baffle-Wall (In-Wall) or Free-Field (On-Wall). Along with the bass adjustment, we also included a high frequency adjustment to compensate the high frequency when the speaker is placed behind a projection screen.
How to adjust the sound

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.

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 screens without any strain!

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.
When a loudspeaker is flush-mounted in a wall, it typically results in approximately 6dB of gain in the 100–200 Hz range. As some listeners may find this tonal balance undesirable, we have included a jumper switch to select the setting that best suits your listening experience.
Custom tuned 1" Thick HDF Cabinet
The Theatrus T80WL in-wall speaker's drivers come packed in a Stealth Black 1" Thick HDF Anti Resonant Cabinet, with a hardened steel front-baffle.
The heat hardened steel is powder coated for effective rust-proofing to last a lifetime.
For a powerful home theater performance, a sturdy cabinet is also 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.
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 T80WL In-Wall speakers feature nifty red dog legs, which make installation a breeze!
Simply locate the 8 (4 on each side) screws that hold the dog legs in-place, get your wiring connected to the speakers, and then grab your trusty torque adjustable drill setting it to a low torque setting, and drill the screw until secure.

Rotatable Easy-Pull Spring-Loaded Logo
