INTRODUCTION Thank you Thank you for purchasing the awesome MSE-118 Quake subwoofer from EM Acoustics. The MSE-118 Quake has been carefully designed and rigorously tested to ensure years of flawless operation and unprecedented sonic quality. The EM Acoustics MSE-118 Quake is designed to provide a smooth and coherent frequency and phase response, whilst having phenomenal power and SPL to enable the Quake to be used in a variety of applications ranging from large nightclubs to full-scale arena tours.
PRODUCT OVERVIEW The MSE-118 Quake is a high power, true horn-loaded subwoofer, designed for the ultimate in low frequency performance. By matching the utmost in drive unit technology with tireless research into the development of horn technology, Quake produces phenomenal performance from an enclosure housing only a single 18” drive unit. The substantial enclosure houses a single proprietary 18” (457mm) drive unit with a 5” (127mm) voice coil.
SYSTEM SETUP Professional loudspeaker systems are potentially dangerous objects if used incorrectly. Please ensure that you read this section fully, and contact EM Acoustics or your local dealer should you be in any doubt over correct operation procedures. Professional loudspeaker systems are capable of producing damage-inducing sound pressure levels, and hence care should be taken when setting your system up, particularly when it comes to loudspeaker placement within a venue.
QUAKE SUBWOOFERS IN USE The Quake subwoofer is designed to be a high performance, world class subwoofer product. You can achieve excellent results with your Quakes, however this section of the manual is vital to ensure you get the best out of them. Please read it carefully, and should you have any questions please do not hesitate to contact either your local EM Acoustics representative or contact us directly at info@emacoustics.co.uk.
Stack Placement In order to reduce the classic “bowling alley” effects when stacks are used in a traditional left/right format, some users prefer to array their Quakes as a single line across the front of the stage. Not only does this method give extra horn area in one place, but will provide an even dispersion rather than a strong +6dB boost on the centreline as with L/R systems. The photo in Fig.
Delay Times Quake is a long horn subwoofer, and as such the drive unit is effectively sitting some distance behind the enclosure when thinking in time. To compensate for this, your system delays should delay your mid/high enclosures back to line up with the Quakes, otherwise the response from the system will be muddy and incoherent. Exact delay times will vary depending on the product being used with the Quakes, and the physical orientation.
MAINTENANCE Your EM Acoustics loudspeakers have been rigorously tested before they leave our factory, to ensure that they give you a lifetime of flawless operation. Should any of your drive units fail and need replacing, please follow the guidelines below. MSE-118: Low Frequency Drive Unit 1.
