Endpoint Mixing® E201 Sound Enhancer
Bring the Endpoint Mixing® experience into your home.
The E201 Sound Enhancer applies our patented layered sound-reproduction principle to the music, movies, and games you already enjoy. Connect your stereo source and two identical speaker pairs to experience greater depth, clearer separation, and a more immersive sense of realism.
Available as an E201 standalone unit or as a complete bundle with two pairs of active speakers.
The Endpoint Mixing® Sound Enhancer Model E201 main unit.
The EM Sound Enhancer is easy to set up.
Audio Line-in:
Use a 3.5 mm audio cable to connect any line-level stereo source to the EM Sound Enhancer.
Audio Outputs:
-
Front Speaker Pair: Connect the front stereo speaker pair using a 3.5 mm audio cable.
-
Back Speaker Pair: Connect the back stereo speaker pair using a 3.5 mm audio cable.

The EM bundle is a compact yet powerful system that employs the novel Endpoint Mixing® sound reproduction method to deliver room-filling, high-quality audio. Its small footprint allows flexible placement, and it connects easily to any stereo sound source.
For improved low-frequency performance, you can optionally add a subwoofer. When doing so, set the subwoofer’s low-pass filter to match the lowest frequency range of the back speaker.

Optimal Speaker Placement
For a Room-Scale Environment
Unlike traditional stereo setups, Endpoint Mixing® (EM) uses a multi-layered speaker arrangement for natural acoustic summation, enhancing depth and realism with minimal room treatment. The front layer is positioned at ear level for clarity, while the back layer is lower to expand depth. The ideal listening spot is at the center of the room, but excellent sound quality extends to nearby positions to the left and right. Using the back layer as a reference, the front layer should be 30% forward, although this can be adjusted between 10% and 40% depending on your room acoustics. While our EM technology ensures excellent sound in untreated spaces, strategic enhancements to room acoustics can further optimize the experience. SIREMIX’s patented Endpoint Mixing® redefines sound quality, delivering a perfectly balanced, deeply immersive, and lifelike listening experience.

Precision Audio for Desktop Spaces
Endpoint Mixing® (EM) enhances nearfield listening, creating a precise and immersive soundstage for desktop setups. The tiered speaker arrangement ensures that direct and reflected sound waves blend seamlessly, enhancing depth and spatial accuracy. Desk reflections with the front speakers may reduce clarity, but using speaker stands or tilting them upward minimizes interference and enhances imaging. The primary listening position is centered at the desk, with excellent sound quality extending across the workspace. Positioning the front layer 30% forward relative to the back layer ensures optimal depth, with flexibility for desk size and acoustics. While EM technology delivers exceptional sound in untreated spaces, simple acoustic refinements can further enhance the experience.

Input Audio Switcher
We recommend adding an Input Audio Switcher to your Endpoint Mixing® setup. This device provides convenient volume control, makes it easy to switch between multiple audio sources, and may improve overall sound quality. Look for a unit that offers a variety of input ports (optical/Bluetooth/analog/USB), volume control, and ideally, a remote control for hassle-free operation.
There are many options, from budget-friendly models to high-end audiophile equipment. As a basic yet versatile example, the FiiO BR13 supports optical, Bluetooth, USB, volume control and delivers good sound quality. A better option is the Topping DX3pro+ which supports optical, Bluetooth, USB, volume control, remote control, LDAC, high-quality ESS chip (ES9038Q2M) and delivers great sound quality.
Key Benefits:
-
Volume Control: Precisely adjust your system’s output level.
-
Multiple Inputs: Seamlessly switch among various devices (e.g., phone, PC, TV).
-
Enhanced Sound Quality: Leverage the DAC’s processing to refine and enrich your audio experience.
-
Upgradability: Easily integrate additional audio sources as your setup evolves.

Certified and Tested Speakers
PreSonus Eris® 3.5
High-quality, active studio monitors that enhance the overall audio experience with precision and clarity. While designed for near-field listening, combining two sets of PreSonus Eris® 3.5 speakers (i.e., four speakers total) can create a wider soundstage with greater depth and clarity. This configuration is ideal for home theater systems and desktop entertainment. Internal tests and user feedback indicate that our system can deliver sound quality comparable to mid and higher-end systems.
Power:
100W
Use case:
Best for regular room-scale environments, and accompanied with a TV set.
Audioengine® A1
Active speakers with a compact footprint, delivering a high-quality audio solution. Although intended for near-field listening, pairing two sets of Audioengine® A1 speakers (i.e., four speakers total) can provide a much wider soundstage with improved depth and clarity. This configuration is ideal for a small-footprint environment, e.g., a desktop. Internal tests and user feedback indicate that our system offers audio quality on par with mid and higher-end systems.
Power:
120W
Use case:
Best for desktop environments.
Klipsch® R-50PM
Delivering high-quality, dynamic sound with a warm tone, these updated powered stereo speakers are suitable for a variety of audio experiences. Featuring a high-performance Class-D amplifier, spun-copper TCP woofers, and a new edge-to-edge Tractrix® horn, these speakers provide robust bass through Dynamic Bass EQ and an exceptionally wide listening area. Enhancing audio performance without any loss of quality, they are ideal for medium to large spaces such as apartments. Combining two sets of Klipsch® R-50PM speakers (i.e., four speakers total) with the Endpoint Mixing® Sound Enhancer E201 creates a significantly wider and deeper soundstage with pinpoint clarity. With up to 240W of peak power output, this setup effortlessly fills a medium-sized home theater and beyond.
In an earlier Endpoint Mixing® listening comparison, an EM reference system using the E200 Sound Enhancer and the previous generation Klipsch® R-51PM speakers delivered nearly 90% of the participant-rated sound quality of a high-end stereo reference system valued at approximately USD 50,000. With the R-50PM’s upgraded acoustics and wider sound dispersion, this modern pairing pushes the system's sonic performance even further past that impressive benchmark. Read the Munich listening report for details. (E200 is an earlier generation of the E201 series product, which delivers an identical sound experience.)
