Theatrus T65SL Dual 6.5" Slim Stack On-Wall LCR Speaker
We are Thrilled to introduce the new Theatrus T65SL On-Wall Speaker. These speakers can blend into your home theater, making them almost invisible. They provide fantastic movie sound without any distractions.
The Theatrus T65SL On-Wall Speaker is ideal for front left, right, and center, as well as surround, but can be used in any position in the home theater system for a detailed and immersive sound stage.

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 T80SL 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 T65SL 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 6.5-inch long-throw Curv Cone woofers, providing a powerful, highly impactful low-frequency soundstage.

Sealed slim LCR design
Achieving exceptional sound quality requires more than just premium drivers—it demands precise control over the acoustic environment in which they operate. Slim on-wall and in-baffle loudspeakers often face significant design constraints, making enclosure integrity especially critical. By utilizing a fully sealed enclosure, Theatrus 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 T65SL 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 T65SL features mounting holes on the back and includes a dedicated wall bracket, making installation quick and easy.

Seamless Integration
Meticulously designed and repeatedly fine-tuned by our dedicated team of engineers, the Theatrus T65SL 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.

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!

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 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 6.5" 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 T65SL 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.

Rubber Bumper Feet Installation
There are four 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.

Sound Adjustment
Located on the back of the speaker, you'll find a Jumper which will be pre-installed in the "Free Field" setting, if you choose to place the speaker behind a projection screen, then you'll simply move the jumper to the "Acoustic Screen" option to boost the High Frequency output by +5dB without any coloration to account for the High-Frequency attenuation that occurs when adding the second acoustically transparent screen or cloth.
Should the bass be too powerful, don't fret! Located next to the high frequency adjustments you'll find a "Baffle-wall (In-Wall) or Free Field (On-Wall) attenuation adjustment, similar to the High Frequency attenuation, except if you choose to change it's position from "Free Field" to "Baffle-wall" you would simply attenuate the select lower-end frequencies by 5dB.
Theatrus' 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.
