Theatrus T80SL On-Wall LCR Speaker

We are delighted to introduce the new Theatrus T80SL 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 T80SL 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.

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.

Powerful Slim Stack LCR speaker

When Aperion Audio began developing the Theatrus series five years ago, 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 T80SL On-Wall Speaker could effectively blend into their surroundings for improved concealment, all while providing an immersive audio experience that meets the diverse needs of our customers.

The decoration style of private custom home theaters is increasingly focused on creating an unobtrusive and streamlined environment.

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.

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.

Three Way Design

The Theatrus T80SL 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_and_Slim_Design

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.

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.

Theatrus_High-End_Crossover

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.

Aperion Theatrus Speaker Sound Adjustment

Sound Adjustment

The Theatrus T80SL 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

Theatrus_Aluminum_Terminal_Plate

Sound Adjustment Jumper

On the aluminum backplate housing the crossover controls on the rear of the T80SL, there are two jumper plugs: one for adjusting the low-frequency response and the other for adjusting the high-frequency response.

Theatrus_High_Frequency_Adjustment

High Frequency Adjustment

If the T80SL 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.

Bass Adjustment

If the T80SL is to be mounted into a wall—where the wall acts as a large baffle that influences low-frequency response—the low-frequency adjustment jumper plug can be set to the "Baffle-Wall (In-Wall)" position to flatten the low-frequency response curve.

Rotatable_Logo

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.

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. 

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.

Sealed slim cabinet design

One of the key steps in achieving sound quality is to contain the sound from the speakers to your room, as opposed to your wall. Theatrus On-wall speakers use a sealed box enclosure.

Easy to mount and install

The Theatrus T80SL features mounting holes on the back and includes a dedicated wall bracket, making installation quick and easy.

Rotatable Easy-Pull Spring-Loaded Logo
