Featuring a 10" (250mm) bass driver and 1" (25mm) compression driver on a 70 x 40 degree horn, it is particularly useful in distributed sound and audio-visual appplications. 3. 3 W2 The W2 is a powerful stand-alone system combining dynamic full-frequency performance with exceptional articulation. [. . . ] 3. 5 WS2A Where a Wavefront Professional Series enclosure requires additional low frequency enhancement, the WS2A will extend the power bandwidth of the system to below 35Hz. It utilises twin high power 15" (380mm) drivers with 4" (100mm) voice coils in an optimally tuned compact reflex enclosure. NOTE: Passive systems such as the W0. 5, WM0. 5, W1, W2 (in passive mode) and CMX2AP may be used without a WX3A controller provided recommended amplifier power is not exceeded and care is taken to avoid amplifier clipping. Use of an optional WX3A controller with its system specific low frequency EQ and built in limiters will result in improved bass response and system protection. All material © 2007.

Please take some time to review the following points concerning safe use of Wavefront Professional Series loudspeakers. Professional loudspeakers are capable of producing extremely high sound levels and should be used with care. Hearing loss is cumulative and can result from levels above 90dB if people are exposed for a long period. Never stand close to loudspeakers driven at high level. 4. 1 Tripod Mounting The W0. 5, W1, W2 and CMX2A incorporate a pole mounting socket to facilitate mounting on tripod stands. When using stands, the following precautions are advised: Ensure that the stand will support the weight of the speaker by checking the stand manufacturers rating. This is because music signals have a high peak-to-average "crest" factor. When an amplifier is severely overdriven, its output waveform is clipped (its peaks are squared off) ­ reducing the crest factor. In extreme cases, the waveform can approach that of a square wave. An amplifier is normally capable of producing far more power under these conditions than its undistorted rated power output. The use of very high power amplifiers with outputs greater than those recommended is discouraged. Care should be taken to avoid switch-on surges, which can result in momentary power peaks in excess of specified ratings. When powering up a sound system it is important to switch on the amplifiers after the mixer and control electronics have stabilised. When powering down the system, reverse the sequence and switch off the amplifiers first. All material © 2007.

The second connector allows use of a short link lead to power another parallel loudspeaker. The connectors are wired as follows: NL4 Pin 11+ 22+ W0. 5/WM0. 5 W1/W2 Passive/CMX2AP/WS2 Input -ve Input +ve N/C N/C W2 Active CMX2A Low -ve Low +ve (Mid)/High -ve (Mid)/High +ve 7 CABLE LENGTHS When connecting loudspeaker systems to an amplifier, it is recommended that the return resistance of the cable used is less than one tenth of the nominal impedance of the system or systems in parallel. [. . . ] Wavefront Professional Series loudspeakers combined with the appropriately configured controller exhibit an essentially flat on-axis frequency response. Equalisation to compensate for a particular acoustic environment may be performed where required. Where loudspeakers are arrayed, they may benefit from a degree of equalisation to reduce the effect of the low/mid build up and tilting of the response inherent in the use of multiple arrayed enclosures. 9 WARRANTY Martin Audio Wavefront Professional Series products are warranted against manufacturing defects in materials or craftsmanship over a period of 5 years from the date of original purchase. During the warranty period Martin Audio will, at it's discretion, either repair or replace products which prove to be defective provided that the product is returned in its original packaging, shipping prepaid, to an authorised Martin Audio service agent or distributor.
