i-12 compound isobaric ULF subwoofer
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 27Hz, with more SPL
available than the smaller i-8. This makes the i-12 the ideal theatrical effects subwoofer system, or an ideal
companion to the EMS-215 dual 15” subwoofer system where extra depth of response is required.
The enclosure comes supplied with steel bar handles as standard and there is an optional transit wheelboard and
protective cover. The i-12 is fitted with Neutrik Speakon TM connectors as standard.
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, and for drive unit
protection a high pass filter is recommended – please see the processing section of this manual for more
information.
