PRODUCT OVERVIEW

EMS-215/215C quasi-bandpass subwoofer

The EMS-215 is a compact, powerful subwoofer product designed for a wide variety of sound reinforcement

applications where compact size and weight are more critical than low frequency extension. It features a pair of

high-power 15” (381mm) neodymium LF drive unit in a quasi-bandpass enclosure, resulting in a response which is

swift and punchy, whilst still retaining usable low frequency extension. The EMS-215C is identical in every respect,

except that the drive units utilise ceramic magnet systems for more cost-sensitive applications.

The EMS-215 is suited to a wide variety of professional audio applications, from corporate and theatre use through

to small-medium scale front of house or nightclub use.

As with all EM Acoustics subwoofers, no programmed EQ is required for correct operation. For normal usage,

active high and low pass filers are required. This is a lot of flexibility in the choice of crossover points, depending

on program material and user taste. Please see page 7 for further information.

The EMS-215 is supplied as standard in black or white, and is fitted with two Neutrik SpeakONTM NL4MPR

connectors. The EMS-215 is also supplied as standard with a set of four tour-grade castors. Custom colours,

weather protection and specific connectors can also be supplied if required –please contact your local EM

Acoustics representative for more details.

SYSTEM SET-UP

Safety Considerations

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. Damage to the ear can result from levels above 90dB under prolonged exposure.

Pole Mounting fullrange loudspeakers from the EMS-215/215C

The EMS-215/215C can be support other loudspeakers using either a standard 35mm pole, or an M20 threaded

pole depending on your choice of hardware. When mounting in this way, please consider the following:

Ensure your stand height is locked off and the system is stable.

Check the weight loading of your poles before attempting to mount the loudspeaker.

Do not stack a second loudspeaker on top of the stand-mounted one.

Ensure cables are run so as to leave enough slack to enable neat wiring, and thus reduce the risk of the

speaker being pulled over. Loose cables should be covered or taped down wherever possible to reduce trip

hazards.

If the system is being used outdoors, it may be necessary to add support to the system to prevent it toppling

over.

Ground Stacking

Ensure that the floor or stage surface can withstand the weight of the system.

Wherever possible, avoid high stacks and use ratchet straps to secure loudspeakers together. Please also

remember that vibrations from subwoofer systems can shake other loudspeakers out of place, which may

present a toppling hazard. The use of ratchet straps and non-slip material is recommended to prevent this.

Cabling and Amplifier Selection

The EMS-215 is designed to be used with professional power amplifiers providing the following power outputs:

EMS-215 1600W/channel into eight ohms

It is good practice to use an amplifier equal to the program power rating of the loudspeaker –so as to retain

sufficient headroom and good dynamic range. Care should be taken during operation to avoid amplifier clipping –

as this can cause serious damage to your loudspeakers. If in doubt, please contact your dealer who will be happy

to assist you in correct amplifier choice and setup.

Cabling

The EMS-215 is supplied as standard with Neutrik SpeakONTM NL4 connectors, wired pin 1+/1-. It is

recommended that the resistance of your cable is less than one tenth of the nominal system impedance. Given

below are the recommended maximum cable lengths for different cross-sections and impedances.

Conductor Cross Sectional Area Maximum Recommended Cable Length

4 ohms 8 ohms 16 ohms

1.0mm211m 22m 44m

1.5mm2 17m 34m 68m

2.0mm222m 44m 88m

2.5mm229m 58m 116m

4.0mm244m 88m 176m

6.0mm266m 132m 264m

Pins 2+/2- on the SpeakONTM connectors are wired together to allow link-through with 4-core cables.

A small power amplifier working too hard is more likely to damage a loudspeaker than a large power amplifier

working within its operating range!

DSP Settings

The EMS-215 requires at the minimum an active low pass filter to function correctly. The settings below are given

as a starting point –as the user you are given maximum flexibility to adjust for your taste. To protect the drive

unit, it is also advisable to apply a high pass filter to the system to protect the EMS-215 drive unit from over-

excursion from frequencies it cannot reproduce. The higher you raise the high pass filter on an EMS-215, the more

headroom and overall sound pressure level output there is available. For most medium-to-high level applications,

we would recommend a minimum of an 40Hz high pass filter with a 24dB/octave slope to sufficiently protect the

loudspeaker. For higher SPL applications, we would recommend raising this filter –we would stress that the

higher the filter, the safer the loudspeaker will be. If you are in any doubt over suitable settings for your EMS-215,

please don’t hesitate to contact EM Acoustics or your local dealer for support and advice.

EMS-215: High Pass Filter: 40Hz, 24dB/Octave Linkwitz-Riley

Low Pass Filter: 125Hz maximum, 24dB/Octave Linkwitz-Riley

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.

EMS-215: Low Frequency Drive Units

1. Using a PZ2 screwdriver, remove the screws securing the grille in place. With the EMS-215, ease the grille out

of its retaining slot. For the EMS-215C, simply lift the grille clear of the enclosure.

2. Using a 5mm Allen key, remove the six M6 socket-head bolts holding the required drive unit in place, and keep

them safe –ensuring you have collected both the shake-proof and flat washers for each bolt. Gently lift the

drive unit out of its locating hole –please take care as it is heavy! Carefully disconnect the cables from the

drive unit.

For the EMS-215C, eight bolts secure each drive unit in place.

3. To reinstate the driver, simply reverse the above procedure. Please observe the correct polarity –red cable to

positive terminal, black cable to negative.

4. Reposition the front grille (on the EMS-215, ease it into the retaining slot) and reinstate the screws.
