DLS COMPETITION subs W310, W312

Thank you for buying a DLS COMPETITION subwoofer. This manual will advice you in your installation. A correct installation is important to achieve the best possible sound from your speakers. The speakers are mainly designed for box mounting. When mounting the speakers "open air" the power handling capacity is reduced with 30% from the nominal value. Use high class speaker wires, min 2.5 mm2. For example DLS SC 2x 2,5.

MOUNTING:

I THE HAT RACK OR BEHIND THE REAR SEAT.
To avoid rattle use a baffle of MDF or particle board, min 19 mm, for speaker mounting. Attach screws to all screw holes and tighten them even to avoid the speaker basket to get inclined.

CONNECTION:

+ Connected with a 6 dB passive low-pass x-over = 6,3 mH coil in series. X-over frequency 100 Hz.

BOX MOUNTING:

A speaker box is normaly made of MDF or particle board, min 19 mm. The box must be air-tight. Use sealing compound in all joints and at the cable entry. Mount screws every 10 cm. Both sealed, vented and most types of bandpass boxes are suitable for DLS COMPETITION subwoofers. The sealed box is good for hard rock and disco music and gives a good control of the cone. The vented box is more efficient and gives a 3 dB higher level than the sealed type. In small vented boxes the ports can become rather long. You can angle the port inside the box or mount it out from the box, for example when the ports are mounted through the hat rack. There must be a free space of at least the port diameter behind the port opening inside the box. Use ports with conical openings to avoid noise at low frequencies caused by air turbulence at the port edge.
Connected with a 12 dB passive low-pass x-over = 10 mH coil in series and a bipolar capacitor of 300 F in parallel. X-over frequency 95 Hz.

Active filter

DIRECTION OF THE BOX:
In a SEDAN-type car the best result is achieved when the box with both speaker and port is directed towards Mono bridge mode with an active low-pass filter before the the rear seat. The port should not be directed up amplifier. Read your amplifiers manual about connecting a sub in through the hat rack if the speaker is directed towards bridge mode. the back of the rear seat. In a large hat rack both speakers and ports can be mounted up through the hat Two 4 ohm subs are normally connected in stereo since most amplifiers cant handle bridge mode connections below 4 ohms. rack with a box under it. We recommend the use of a subsonic highpass filter. This gives A bandpass box is normally installed with all port a better bass reproduction with less "rumble". In DLS and openings up through the hat rack. GENESIS amplifiers this feature is built-in. In a small car like VW GOLF or similar, and also in If you want to connect one or more subs in some other way, station wagon types the box should be directed towards contact your local dealer for advice. the back of the car.

CLASSIC SERIES SUBWOOFERS

WELCOME

Thank you for buying a DLS CLASSIC subwoofer. The subwoofer must be installed correctly in order to work well. This manual will show you how to install it like a pro. Please read the entire manual before beginning the installation. Install the subwoofer yourself if you feel confident with our instructions and if you have the proper tools. However if you feel unsure, turn over the installation job to someone better suited to it. The speakers are designed for enclosure mounting. When installed "open air" the power handling capacity is reduced with 30% from the nominal value. We dont recommend open air installations except for OA8, OA10 and OA12 which are designed for open air installations.
W308B, W310B, W312B OA8, OA10, OA12
SUBWOOFER ENCLOSURES, GENERAL
Build your enclosure in a stable and airtight material. The best is MDF-board, 19 mm, or particle board, 22 mm. Larger enclosures must have bracing inside to avoid vibrations. The enclosure must be completely airtight. Use sealing compound in all joints, also around the cable terminals. The size of the enclosure is decided by the speaker data.

SEALED ENCLOSURES

Sealed enclosures are easy to build. The size is not critical, but it cant be too small. The speaker data such as Fs, Qts, Vas and X-max decides the size of the enclosure. Large speakers need larger boxes. Two speakers need a box of the double size etc. The enclosure must be completely airtight. A sealed enclosure should be filled with acoustic wool up to 75 - 100%. A sealed enclosure has a lower efficiency than vented enclosures but they can handle high power and are easy to build. A subwoofer in a sealed enclosure creates a tight bass suitable for the audiophiles listening to classical music, jazz and soft rock. All the Classic subwoofers except for OA12, are recommended NOT to use in sealed enclosures.

CONNECTION OF SUBWOOFER

How to connect depends on what type of amplifier you use. The best is to follow the instructions given in the manual for the amplifier. Most amplifiers today have builtin lowpass crossover and possibilities to connect your subwoofer in bridge mode. Two 4 ohm subwoofers are often connected in stereo mode since most amplifiers cant handle bridge mode loads below 4 ohms. If you have a DLS Ultimate amplifier its possible to connect two 4 ohm subs in bridge mode, these ampliers are 1 ohm stable. We also recommend the use of a subsonic highpass filter. This gives a better bass reproduction with less "rumble". In most DLS amplifiers this feature is already built-in. For wiring use high class speaker wires, min AWG13 (2.5 mm2). For example DLS SC 2x2,5. If you have an amplifier without built-in crossover you must use a passive crossover between amplifier and subwoofer like in this example:

VENTED ENCLOSURES

A speaker in a vented enclosure has a higher efficiency (3 dB) and higher power handling capacity than in a sealed enclosure. In a vented enclosure the sound from the speaker and the port work together creating a higher sound level. The sound from the port must come out in the same phase as from the speaker otherwise the result is bad. The size of the vented enclosure is decided by the speaker data just as for the sealed one. The size of the vehicle often decides the practical size of the enclosure. A smaller enclosure has a higher resonant frequency than the larger one. The size of the enclosure should not be so big that the speaker plays below its own free air resonance (Fs), then it looses in power handling capacity. The port does not have to be fully inside the enclosure as long as the area and length are correct. Sometimes you need two or more ports in an enclosure. You can convert from one to two or more ports as long as the total port area is the same.

C Connected with a 12 dB passive low-pass x-over = 10 mH coil in series and a bipolar capacitor of 300 microFarad in parallel. Crossover frequency is 95 Hz.

BANDPASS ENCLOSURES
In all bandpass enclosures the speakers are hidden inside the enclosure, all sound is coming out through the ports. There are different types of bandpass enclosures and they have in common that they are a bit more difficult to build. Most of our subwoofers can be used in bandpass enclosures

*** It is impossible to have a 44 cm port inside a 15 liter enclosure! If you want to use the vented box just cut the port tube 2,5 cm / 1 from the back wall for a good function. Doing so the subwoofer sees the port to be longer than it is because the short distance between port and back wall has an influence on the air flow through the port.

HINTS & TIPS FOR DO IT YOURSELF ENCLOSURE BUILDERS
ABOUT THE RECOMMENDED ENCLOSURES
The performance of these recommended enclosures will vay from vehicle to vehicle. It is more difficult to get a tight and well defined bass in a SEDAN vehicle because of the tightness between trunk and interior of the vehicle. In this case a bandpass box could be a better choise. - All volumes are inside measures. - Volumes occupied by speaker and ports have already been added to the given enclosure volumes. - Use conical bass ports for best result. (DLS BP-75 or BP-110). If the ports are too long for the box you can use a bend. Either cut the tube and glue it together in angle, or use factory made tube bends. Its easier to use the factory made ones. The total length must be the same as for a straight tube. Make the measure in the center of the tube. The port opening inside the enclosure must not be closer to an interior wall than 3 (75 mm), otherwise it will have negative effects on the airflow. - The enclosure must be very steady and completely airtight. Use 22 mm particle board or 19 mm MDF-board. The particle board has a self resonant frequency of 14 Hz while the MDF has a resonant frequency of approx. 400 Hz. Its important to do some type of bracing inside the enclosure to avoid vibrations. Volume taken up by bracing should be added to the enclosure volumes.
ENCLOSURE PLACING IN DIFFERENT TYPES OF VEHICLES
In small vehicles like VW Golf, Peugeot 306 and similar the bass box should be installed with both speaker and port directed backwards. Alternatively booth speaker and port can be directed upwards. This way of mounting is valid for all types of vehicles where the trunk is incorporated with the inner compartment. In sedan vehicles with the passenger compartment separated from the trunk, the enclosure should be installed with booth speaker and port directed towards the rear seat. Some cars have an opening in the middle of the rear seat for loading skis etc. You can install the enclosure behind this opening and direct speaker or port through this opening. There must be some free space in front of the port, (between the rear seat and the port opening). In large vehicles like station wagons the best sound is achieved with the enclosure installed behind the rear seat with booth speaker and port directed backwards. Alternatively you can install the enclosure on one side of the luggage compartment.

CALCULATE YOUR ENCLOSURE

Box volumes: When caculating the volume of an enclosure you simply multiply the width (W) x heigth (H) x depth (D). Use measures in dm and you will get the answer in liters. A trapezoid box is calulated as below: Vol=width (W) x heigth (H) x upper depth(UD) + lower depth(LD) 2 W UD H LD Be sure to measure the inside dimensions.

ENCLOSURE DAMPING

Most enclosures should be damped inside with syntetic (acoustic) wool or damping mat (line). Attach the damping material on the wall opposite from the speaker and port. A sealed enclosure should be filled up to 70-100% with acoustic wool. In a vented enclosure the speaker and port should be on the same side, otherwise a fade-out of some frequencies can occour. In most vehicles, except for SEDAN cars, the speaker and port should be directed backwards for best result.
