NS-555 belongs to the 3-band type of acoustics. The frequency range spectrum is correctly distributed between 4 speakers - two low-frequency 16 cm (6.5”), a mid-frequency 13 cm (5.25”) and an aluminum tweeter 1” (2.5 cm), which allows the speaker system to sound in the range from 35 to 35,000 Hz. The speakers are made according to the Waveguide horn principle with PMD membranes (Polymer-injected Mica Diaphragm).
NS-777 belongs to the 3-band type of acoustics. The frequency range spectrum is correctly distributed between 4 speakers - two low-frequency 20 cm (8”), a mid-frequency 13 cm (5.25”) and an aluminum tweeter 1” (2.5 cm), which allows the speaker system to sound in the range from 30 to 35,000 Hz. The speakers are made according to the Waveguide horn principle with PMD membranes (Polymer-injected Mica Diaphragm).
Although the NS-F51 has 3 speakers, it still belongs to the 2-band type of acoustics. Two low-frequency speakers with a diameter of 16 cm (6.5”) each transmit smooth sound (without dips) over a wide range, and a standard tweeter tweeter (Ø 3 cm) complements the frequency spectrum in a high register. It is this type of speaker system device that provides sound from 43 to 26,000 Hz. It is worth noting the presence of magnetic protection, which allows you to install the speaker in close proximity to other types of equipment (televisions, amplifiers, etc.)
The model has a three-way design, it uses new dynamic radiators of the company's own design. Diffusers made of a mixture of ZYLON composite material and spruce wood fibers are installed in them. The high-frequency range is voiced by a tweeter with a 30 mm dome, an 80 mm dome driver is responsible for the middle frequencies, two 160 mm speakers with continuous profile diffusers operate on the bass.
