Watch for these symbols:
The lightning ash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated
“dangerous voltage” within the product’s enclosure, that may be of sucient magnitude to constute a risk of electric shock to
persons.
The exclamaon point within an equilateral triangle is intended to alert the user to the presence of important operang and
maintenance (servicing) instrucons in the literature accompanying the appliance.
IMPORTANT SAFETY INSTRUCTIONS
1. Read these instrucons.
2. Keep these instrucons.
3. Heed all warnings.
4. Follow all instrucons.
5. Do not use this apparatus near water.
6. Clean only with dry cloth.
7. Do not block any venlaon openings. Install in accordance with the manufacturer’s instrucons.
8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including ampliers) that
produce heat.
9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than
the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the third prong are provided
for your safety. If the provided plug does not t into your outlet, consult an electrician for replacement of the obsolete outlet.
10. Protect the power cord from being walked on or pinched, parcularly at plugs, convenience receptacles, and the point where
they exit from the apparatus.
11. Only use aachments/accessories specied by the manufacturer.
12. Use only with the cart, stand, tripod, bracket, or table specied by the manufacturer, or sold with the apparatus. When a cart
is used, use cauon when moving the cart/apparatus combinaon to avoid injury from p-over.
13. Unplug this apparatus during lightning storms or when unused for long periods of me.
14. Refer all servicing to qualied service personnel. Servicing is required when the apparatus has been damaged in any way, such
as power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has
been exposed to rain or moisture, does not operate normally, or has been dropped.
15. Warning: to reduce the risk of re or electric shock, do not expose this apparatus to rain or moisture.
16. Do not expose this equipment to dripping or splashing and ensure that no objects lled with liquids, such as vases, are placed
on the equipment.
17. To completely disconnect this apparatus from the ac mains, disconnect the power supply cord plug from the ac receptacle.
18. The mains plug of the power supply cord shall remain readily operable.
19. This apparatus contains potenally lethal voltages. To prevent electric shock or hazard, do not remove the chassis, input
module or ac input covers. No user serviceable parts inside. Refer servicing to qualied service personnel.
20. The loudspeakers covered by this manual are not intended for high moisture outdoor environments. Moisture can damage
the speaker cone and surround and cause corrosion of electrical contacts and metal parts. Avoid exposing the speakers to
direct moisture.
21. Keep loudspeakers out of extended or intense direct sunlight. The driver suspension will prematurely dry out and nished
surfaces may be degraded by long-term exposure to intense ultra-violet (UV) light.
22. The loudspeakers can generate considerable energy. When placed on a slippery surface such as polished wood or linoleum,
the speaker may move due to its acouscal energy output.
23. Precauons should be taken to assure that the speaker does not fall o a stage or table on which it is placed.
24. The loudspeakers are easily capable of generang sound pressure levels (SPL) sucient to cause permanent hearing damage
to performers, producon crew and audience members. Cauon should be taken to avoid prolonged exposure to SPL in excess
of 90 dB.

INTRODUCTION
The SW18P is a high-power compact subwoofer that provides extended low frequency response for specic models in the ED series
of high performance point source loudspeakers. It is suitable for the use in live music venues, nightclubs, barss houses of worship
and for corporate and A/V applicaons.
The SW18P subwoofer system is equipped with a high power 18” (460mm) transducer capable of long excursion (up to 30mm peak-
to-peak), controlled by high sness Double Silicon Spider as centering suspension that maintains linear voice coil travel even at
high output levels. The motor structure features high strength (BL²/Re) with opmized symmetry and excursion controlled by Inner
Flux Demodulang Ring. The robust copper 100mm (4”) voice coil is wounded in two dierent layers both outside and inside the coil
support, then doubling the coil surface exposed to air cooling and consequently improving the long term thermal capacity of the
loudspeaker. Cones are made of very high-sness glass ber reinforced paper, featuring also invisible water repellent treatment.
The 15mm phenolic birch plywood cabinet is provided with an M20 pole mount socket to allow two-way ED series loudspeakers to
be mounted above on a speaker pole. Recessed handles are provided for easy liing and handing and the included polyurethane
wheels aid transportaon, while stacking feet and matching recesses enable secure ground stacks. Two Neutrik® speakON™ NL4
connectors provide input and link connecons.
