Alpha Series description
Loudspeakers
The Alpha range includes the following speakers:
•
The S2 Sub-bass is a double 18-inch resonator loaded sub-bass, dedicated to very low
frequency reproduction (< 80 Hz).
•
The B1-15 & B1-18 are complex loaded (bass-reflex & exponential horn) bass cabinets;
the B1-15 houses one 15-inch driver, while the B1-18 houses one 18-inch driver;
frequency response ranges from 40 Hz up to 200 Hz.
•
The Mid-high M3 & M8 are concentric horn cabinets dedicated to the 200 Hz - 20 kHz
frequency range reproduction; the MF range is handled by two exponential horn loaded
10-inch drivers whose response is optimised by two Nexo designed phase plugs; the HF
range is handled by one constant directivity horn loaded two-inch Neodymium driver. M3
coverage is 35° (H) x 35°(V), M8 75° (H) x45° (V).
•
The Mid-high EM forms part of the recently introduced Alpha E Series; its size and power-
rating is smaller than that of the Alpha M3 & M8; the mid range is handled by an
exponential horn loaded 10’’ driver, while the HF range is handled by a constant directivity
horn loaded ceramic 2’’ driver. Alpha EM coverage is 75°x30°.
•
The compact EF is dedicated to the full audio range reproduction 40 Hz – 20 kHz; it
consists of one EM and one B1-18 stacked in a monoblock compact format.
Alpha cabinet formats are designed for optimal array assembly (see section “D
IMENSIONS
” p.34); all
the cabinets have the same width and depth; height is in multiples of 200 mm UNITS.
