Gradient Helsinki utilizes Controlled Directivity, the very essence of the unique Gradient loudspeaker design philosophy. By directing more of the speakers high frequencies and middle frequencies to the listener and less to the reflecting surfaces, the listener hears more of the original recording and less of the room.
Rooms develop strong peaks and dips below 200Hz – these are determined by the three dimensions of the room i.e. the Length, Width and Height. The most audibly damaging node arises from the shortest room dimension, usually the floor to ceiling height.
Dipole bass stimulates bass in just one direction (the direction of driver excursion) and not the other two. In this way, the speaker reduces nodes due to the ceiling height and the direction 90 degrees from the radiating direction.
The bass part of the Gradient Helsinki loudspeaker consists of one 30cm custom-made long throw woofer. It is assembled on an open baffle, giving the low frequencies a "figure eight" or dipole radiation pattern.
Experience effortless connection with the Helsinki 1.5, featuring the premium Neutrik speakON connector as Gradient's standard choice. The lockable speakON not only ensures convenience but also enhances safety, establishing a superior electrical connection unmatched by any other speaker connector.
Gradient loudspeakers are manufactured from high quality materials and components. The performance of the drivers used have been tested before the assembly. After the assembly, a precision measuring system ensures that all speakers are of a similar high standard. The inspection marking and the serial number are located on the back of the speaker.
In line with Gradient's unwavering commitment to quality, the Helsinki 1.5 is meticulously crafted by hand in Finland. This dedication to craftsmanship not only ensures exceptional quality but also guarantees the longevity of your investment. Gradient has been granted the right to use the Key Flag symbol as a sign of Finnish work.
