Introduction

DDX Series

Four black rectangular electronic speakers with hexagonal bases, arranged in ascending size from left to right (no text or symbols visible)

Thank you for purchasing this Martin Audio DDX loudspeaker system.

The Martin Audio DDX Series has been designed to deliver high performance sound in permanent installations or as a portable system.

All DDX loudspeakers are constructed from birch/poplar plywood and finished with a durable black textured paint, with white a white option available to order.

DDX full range loudspeakers use two-way, full-range patent protected coaxial differential dispersion drivers. They have an internal passive crossover for cost effective and easy deployment.

The DDX118 subwoofer uses a high performance 18" driver in a cabinet tuned to give best possible performance.

A range of installation accessories is also available. Wall brackets is suitable for first and second fix construction industry conventions.

The user guide provides a detailed explanation of the DDX's features and options. Please take the time to read through the guide before deployment.

Safety First

Professional loudspeakers can produce 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.

Coaxial Differential Dispersion Technology

All DDX Series full-range models feature Martin Audio's unique, patent protected coaxial differential dispersion technology.

Non-coaxial systems can suffer from uneven frequency response in the crossover region because of interference between the LF and HF sections. Depending on the listening position, this causes off-axis variations in frequency response.

A disadvantage of conventional coaxial devices is that coverage angle reduces at higher frequencies, due to inadequate waveguides. DDX devices overcome this by using a static waveguide that merges seamlessly with the unique cone shape, maintaining the dispersion pattern even at very high frequencies.

A differential dispersion driver has an asymmetric coverage pattern. Wide coverage at the bottom of the vertical coverage angle and narrower at the top. This covers the target area more evenly than a system with a conventional, fixed-dispersion type driver as the wide section covers more audience in the near field, and the narrow section projects sound better to the rear of the space.

All DDX Series loudspeakers have threaded inserts available for flown applications in fixed installations. Full range cabinets have M8 inserts and subwoofers have M10 inserts. The inserts can be used for fitting bespoke flying hardware or eye bolts. These must be forged steel shouldered types certified with a safe working load of the cabinet weight.

Do not be tempted to use formed steel types commonly available from DIY stores as they are unsafe for flying heavy loudspeaker cabinets. Correctly rated shouldered eye bolts are available from Martin Audio as an optional accessory.

Installation

Pole Mounting

When using poles or stands, the following precautions are advised:

• Ensure that the stand will support the weight of the loudspeaker by checking the stand manufacturers rating. (See the technical specifications for individual DDX weights and dimensions.)
• Make sure that the stand is placed on a level surface and that its legs are fully extended.
• Do not place more than one loudspeaker on each stand.
• Run cables so that they do not present a trip hazard which could pull the loudspeaker over.
• When used outdoors in the wind, it may be necessary to add some weight to the base of the stand.
• When using a pole mount with a sub-bass system, observe similar precautions.

Stacking

• Ensure that the floor or stage is level and solid.
• Do not stack loudspeakers too high outdoors where winds could topple the stack.
• Be aware that loudspeakers producing very high sound levels can move or creep. To avoid this, place friction material between the floor and loudspeaker and between each loudspeaker or use strapping to secure the stack.

Wall Mounting

DDX8, DDX10 and DDX12 may be wall mounted either in portrait or landscape orientation.

Do not forget that it is important to rotate the driver through 90° when using a DDX cabinet in landscape mode. Please see the chapter on grille removal and driver rotation for details on how this is achieved.

Installation is a two-part process in common with standard first fix and second fix procedures, installation using both sizes of brackets is identical, the WB10/12 bracket is just larger than the WB6/8 version.

The first step is to separate the two halves of the bracket. There are two horizontally mounted nut and bolts holding the two halves together. The upper one which sits in a curved slot does NOT need to be removed. Unscrew the lower bolt and the cabinet bracket will lift off the wall bracket.

Speaker Section Wall Section

First fix is to secure the wall section of the bracket. This is the part with four mounting holes, a vertical bolt holding the section which allows horizontal adjustment and the slot into which the cabinet bracket bolt sits. Use appropriate wall fixings suitable for the composition of the wall. These must be of sufficient strength to support the weight of the loudspeaker; 8kg for the DDX8, 14kg for the DDX10 and 17kg for the DDX12.

The next step is to attach the cabinet section of the bracket to the cabinet. This is the bracket with four countersunk fixing holes on a square pattern with the horizontal bolt in the curved slot.

The rear of the cabinet has six countersunk bolts fitted designed for use with the mounting brackets. For portrait mode remove the lower four bolts, for landscape mode remove the middle four.

Position the bracket over the required holes that suit the orientation required and screw into place tightly using the bolts removed from the cabinet.

You are now ready to fit the loudspeaker to the wall. Offer the loudspeaker up to the bracket so you can hook horizontal bolt in the curved slot onto the notch on the ball bracket. Make sure that you follow appropriate safety measures if you are working at height such as using a scaffold tower or lifting platform which allows you to safely use both hands for this.

Final adjustments can now be made. Horizontal (pan) adjustment is available by rotating the assembly on the vertical bolt. When you are happy with the angle, the vertical securing bolt can be tightened. For WB8/6 use an M5 hex key and for WB10/12 use an M6 hex key.

Horizontal Pivot Bolt Vertical Pivot Bolt

Vertical (tilt) adjustment is made by adjusting the grub screw.

Once the vertical position is fixed the two horizontal bolts can be tightened. This is best achieved by using a socket set with an extender bar to reach the bolt heads.

Eye Bolts

All DDX systems have threaded inserts rated for flown installations. Full range enclosures have M8 threaded inserts and subs have M10 inserts. Most commonly these are used in conjunction with shouldered eye bolts for suspending the cabinets using appropriately rated chain or steel wire. Martin Audio's HTK00003 (M8) and HTK00004 (M10) are rated for use in flown applications. Note that if you plan to use alternative eye bolts these must be shouldered cast steel, not formed steel types commonly available from DIY stores. They must have a safe working load rating compatible with the weight of the cabinets.

All models can be flown in portrait or landscape format. Note that the driver must be rotated when the cabinet is used in landscape mode. Please see the chapter on grille removal and driver rotation.

We recommend using a minimum of four eye bolts with which to suspend the cabinet irrespective of which orientation is used. In most applications, two eye bolts are used as the primary support left and right. A third attaches to the rear of the cabinet and is used to adjust the down-tilt of the cabinet as required. The fourth eye bolt is used to attach a secondary safety line which should be attached to a secure mounting point, which is independent of the primary flying point, around a girder or similar.

Suspending the Cabinet

WARNING: Suspending the system should only be done by qualified personnel following safe rigging practices. Secure fixings to the building structure are vital. Seek help from architects, structural engineers or other specialists if in any doubt.

DDX Series enclosures can be suspended singly by means of the threaded inserts provided. Enclosures are fitted internally with steel corner reinforcement brackets, where necessary, to ensure that each cabinet is strong enough to be hung from its top.

• Never suspend one enclosure from another to form an array or cluster using these fittings.
• Only use forged shoulder eye bolts. It is important that the thread length is at least 30mm.
• Formed eye bolts i.e. those which are formed from a steel rod bent into an eye are not recommended.
• Eye bolts are strongest along the thread axis. Angling the enclosure will result in an angle pull and it is important to use eye bolts that are safe in these circumstances.
• Check that the eye bolt has a safe working load that is greater than the weight of the loudspeaker being suspended.

Mounting Location

For optimum performance it is recommended to mount the loudspeakers above head height as this gives clear line of sight to the target area.

Vertical aiming angles for DDX loudspeakers are generally less than needed with a symmetrical dispersion loudspeaker. Mapping DDX in simulation software such as EASE will help decide how much vertical angle is appropriate.

First and Second Stage Fixing

Construction industry practice favours first and second fixing stages. This system gives installers the advantage of being able to pull cables and make primary fixings at an earlier stage of building completion and avoids the potential problems of leaving expensive and delicate audio equipment in-situ while building and decoration work is still ongoing.

All DDX Series wall brackets disassemble into separate first fix and second fix components. This means that part of the bracket may be secured to the wall or ceiling at first fix, without the necessity of having the cabinet on site. The rest of the bracket can then be fitted to the cabinet at floor level at second fix and then the two parts of the bracket easily mated.

The two fixing stages may be summarised as follows.

First Stage Fixing

Attach first fix sections of wall brackets at desired locations. Run loudspeaker cables to loudspeaker locations, using cable access holes provided in brackets.

Important information: Consult a qualified structural engineer with a full knowledge of the building, its load ratings and your intended loudspeaker installation plans before commencing any installation. The type and size of fixings used must take into account both the weight of the enclosure and the construction of the wall or ceiling.

Second Stage Fixing

Attach second fix sections of brackets to rear of cabinets. Raise cabinets to height and mate with first fix bracket sections. Adjust pan and/or tilt as required.

Important information: In some cases, local regulations may require a safety bond (e.g. wire or chain) to form part of the final fix. The complete installation should be checked and approved by a qualified structural engineer and a qualified electrical safety consultant before being signed off.

Grille Removal and Driver Rotation

The DDX full range cabinets may be used in portrait or landscape orientation. For the loudspeaker to perform correctly when in landscape orientation it is necessary to rotate the driver through 90° to preserve the asymmetric dispersion. The loudspeakers are designed to make this as straightforward as possible with spring-loaded grilles which are easily removed, and with drivers secured with hexagonal head screws. It is also possible to rotate the Martin Audio badge on the grille.

Grille Removal

No screws are used to hold the grille in place. The grilles are manufactured with a natural spring which holds them in place within slots on each side of the cabinets.

The grilles have two or three gaps in the sides into which an appropriately sized flat-bladed screwdriver can be inserted to remove the grille.

Insert the screwdriver blade into one of the gaps, either at the top or bottom of the cabinet.

Gently push the handle down. This will ease the grille out of the slot, it may have bitten into the paint surface so you just need to make sure it is free to be lifted clear.

Now lift the handle up. This will ease the grille forward slightly to prevent the return on the grille dropping straight back into the slot.

Repeat this process for the remaining gaps in the grille to ease it out of the slot all the way up one side of the cabinet. When you get to the final gap the grille should pop out and away from the front of the cabinet.

To replace the grille, first insert one side into the slot on one side of the cabinet. Make sure the return on the grille is completely engaged in the slot. Push on the front of the grille with the flat of your hand, which will encourage the other edge of the grille to locate on the side of the cabinet close to the slot. Now push the edge of the grille back starting at the top or the bottom to engage the return in the slot. You may need to do this a little at a time, working down the length of the grille until it pops into place.

Driver Rotation

DDX loudspeakers are shipped from the factory ready for deployment in vertical – or portrait – orientation. If the loudspeakers are installed horizontally, the coaxial driver must be rotated through 90° to maintain the correct dispersion patterns.

DDX coaxial drivers are not symmetrical. For correct dispersion characteristics the driver should always be orientated as shown, with the narrowest part of the HF waveguide towards the bottom of the enclosure.

To rotate the driver, proceed as follows once the grille has been removed:

Using a hex key:

DDX8 4 mm

DDX10 4 mm

DDX12 5 mm

DDX15 5 mm

Remove the screws securing the driver to the baffle board. There will be between four and eight screws depending on the loudspeaker model.

Lift the driver assembly out and rotate it through 90°.

Replace the bolts and the grille.

Note: If the loudspeaker in portrait mode is installed upside down the driver must be rotated through 180° to ensure the correct dispersion characteristics.

Badge Rotation

In landscape the Martin Audio badge should be rotated on the grille. The badge is spring-loaded and very easy to rotate.

The badge is easier to rotate if the grille is first removed. With the grille removed push the spigot holding the badge into place so that the badge is protruding forward from the grille and is proud of the recess in which it sits. Rotate the badge as required and release the spigot on the rear so it settles back into the recess in the grille.
