The Thetis 340 subwoofer is a must-have for any home theatre system. It'll be a great match for your music system because it's so versatile. It comes with a 25cm speaker and a 250W amplifier, ensuring a unique and immersive experience.

Powerful Output

The Thétis 340 boasts a power of 250W/150W RMS and 400W/250W peak, thanks to the latest generation of Class-D amplifiers. It's simple to tune the Thétis subwoofer to your primary speakers thanks to the steep crossover slopes.

Bass-Reflex Configuration

The subwoofer maintains a limited volume despite its extended performance by utilizing a bass-reflex principle. Airflow noise is greatly reduced when using a laminar port. The Class D amplifier produces 250 watts RMS and 400 watts peak of power.

Variety of Ports

The Thetis subwoofer includes a variety of inputs, allowing them to be connected to a variety of amplifiers. It has a direct LFE input, standard RCA inputs, and high-level inputs for amplifiers with no suitable output. You can adjust the volume, the phase, and the frequency roll-off for a perfect fit with your main speakers.

Easy to Use

The Thetis subwoofer comes with remote control and a front-panel LED display that indicates the sound settings. It has an Automatic Power On feature. The Auto function of the subwoofer can also be used to enable automatic standby. To save energy, an automatic standby is enabled after 20 minutes if there is no signal. The subwoofer is automatically reactivated when a new signal is received.

Successful Design

This subwoofer has great power handling, reproducing all types of dynamics without difficulty, thanks to oversized engines and controlled suspensions. The transducers use composite membranes made of cellulose and carbon, that ensure high rigidity.
