Our goal with Ethos was simple: build speakers that make getting great sound from a turntable as easy as possible. Many contemporary speakers rely on digital signal processing (DSP) to correct an otherwise imperfect frequency response. But what’s the point of listening to vinyl if the analog signal is being converted to digital? That’s why Ethos has a fully analog signal path. As the signal travels from the RCA inputs to the speaker drivers, it’s never converted to digital or enhanced using digital processing.

Instead of digital equalization, we rely on good old-fashioned loudspeaker design. Proper speaker design requires choosing the right drivers, building the right cabinet and crossover components, and then fine-tuning acoustic and electrical parameters to achieve the desired performance. It’s like perfectly lighting a scene before taking a photo with a film camera, as opposed to shooting with your phone and adding a filter. It’s not the easiest way to do it, but it can get the best results.

We are fortunate to have a team of dedicated and talented assembly technicians that truly understand what goes into making great products. Being on the Techoono assembly team requires technical expertise, attention to detail, and a commitment to quality.

Ethos production starts with the amplifier assembly. The PCBA, heat sink, and transformer are fastened to the back plate and connected together. We use torque-controlled screwdrivers and thread-locker to keep fasteners tight even during extreme vibration.

We examine each speaker cabinet the same way we would a turntable plinth – inspecting for imperfections before continuing. Foam gaskets areapplied to the cabinet to ensure all the seals between components are air tight, which is critical for performance. Next, the amplifier assembly, woofer, and tweeter are each carefully installed in the cabinet.

Once the cabinets are sealed up, we perform electrical safety testing. Then the speakers are placed into an anechoic test chamber for acoustic testing. We use an Audio Precision audio analyzer and calibrated measurement microphones to test the frequency response of each speaker.

The speakers are polished and placed in cotton bags before getting boxed up. We’ve been perfecting Ethos for over three years, and we’re excited for you to finally hear them.
