Delta 4 R8

Delta 4 R8

Delta 4 R8 systems have 87 dB/2,83 V sensitivity and a maximum handling power of 250 watt rms. The transducers are three for each speaker. The height is 55”. With a 30° orienting of the systems towards the inside of the listening area they can produce an NPS Horizontal acoustic field.
The floor standing Delta 4 R8 systems have original emission characteristics that let them offer a quality of listening well above that of similar or even higher priced traditional competitors. The 10” woofer allows it to reach, with a smaller size, low end performances very similar to that of the Delta 4 R9.
Belonging to the floor standing Delta group guarantees Delta 4 R8 a vertical dimension of the virtual scene and an auto-dimensioning of the acoustic source is impossible to achieve with traditional systems.
The extended and linear frequency response allows a first order tonal neutrality, while the dynamic capacity is adequate to satisfy large domestic listening environments also.
The 8 ohms impedance allows the use of any kind of power amplifiers.
The mid-high section, as for the biggest Delta 4 R10 model, includes push-pull planar transducers only.
Delta 4 R8 have 24 kt gold plated connections for bi-wiring and bi-amping.
Crossover network doesn’t utilise electrolytic capacitors.
