The new subwoofers are said to be suitable for both home theater and stereo use, and are equipped with downward-firing drivers in the sizes 25cm (Thetis 340) and 20cm (Thetis 300). Additionally, the two subwoofers feature a laminar bass reflex port, which is supposed to significantly reduce air flow noise.
The transducers consist of composite membranes made of cellulose and carbon, which aim to ensure high rigidity. The subwoofers are equipped with Class D amplifiers and are said to have an RMS power of 250 watts (Thetis 340) and 150 watts (Thetis 300). Adjustment to loudspeakers is supposed to be easy due to the high slope of the crossovers. Volume, phase and frequency drop can also be adjusted manually, while volume and standby can also be changed via the remote. The Thetis subwoofers also have an automatic standby that turns the devices off after 20 minutes of inactivity and switches them back on when a new signal is received.
Both subwoofers have a direct LFE input for home theater setups, as well as RCA and high-level inputs for amplifiers without a specialized output.
