i-8 compound isobaric subwoofer
The i-8 is a subwoofer designed to create the depth and authority in low frequencies that is normally associated
with large systems, but in a compact package for ease of installation. Consequently, the i-8 has a frequency
response down to 35Hz yet is small enough to be concealed underneath sofas or in small wall cavities. The i-8 -
although small in size – has enough SPL output to be of use for nightclub or corporate applications, and even for
small FOH systems underneath EMS-81 enclosures. The i-8 subwoofer houses four 8” (203mm) long excursion low
frequency drive units, arranged as two isobaric pairs. This loading allows the enclosure to reproduce frequencies
not normally achieved from an enclosure of this size.
The enclosure is fitted with sixteen M10 threaded fixings, to allow overhead suspension in applications where floor
space is not available. Standard connectors for the i-8 are Neutrik Speakon
TM NL4MP, although alternatives can be
supplied on request.
As with all EM Acoustics products, no external equalisation is necessary to get the enclosure to perform as
specified. An active low pass filter is however required below 150Hz for correct operation.
i-12 compound isobaric subwoofer
DA-1 Ready
The i-12 is the bigger brother of the i-8, and utilises the same enclosure technology. Four high power, long
excursion 12” (305mm) drive units are contained within the compact enclosure, again arranged in a compound
isobaric format. This loading allows the i-12 to effortlessly reproduce frequencies as low as 25Hz, with more SPL
available than the smaller i-8. The enclosure comes supplied with heavy-duty castors and steel bar handles as
standard, and as with other EM Acoustics products is fitted with Neutrik Speakon
TM connectors as standard. The i-
12 can also accept the DA-1 digital power amplifier module.
As with all EM Acoustics products, no external equalisation is necessary to get the enclosure to perform as
specified. An active low pass filter is however required below 100Hz for correct operation.
