REFERENCE SERIES

SUBWOOFERS

RW15

WELCOME

Thank you for buying a DLS REFERENCE 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 in- stallation.

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. In "open air" installations the power handling capacity is reduced by 30% from the nominal value.

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 built- in lowpass crossover and possibilities to connect your subwoofer in bridge mode.

Two 4 ohm subwoofers are often connected in stereo mode since most amplifiers can´t handle bridge mode loads below 4 ohms. If you have a DLS Ultimate amplifier it´s possible to connect two 4 ohm subs in bridge mode, these ampliers are 1 ohm stable.

RW15 has double four ohm voice coils which makes the subwoofer more flexibl. You can connect a single voice coil in 4 ohm. If you want to use both voice coils you can either connect them in series to 8 ohm or in parallell to 2 ohm. If you want to connect more than one subwoofer the dual voice coils system gives you great possibilities to connect in a way that suits your amplifier.

We also recommend the use of a subsonic highpass fil- ter. 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.

WARRANTY SERVICE

This speaker is covered by warranty, depending on the conditions in the country where it is sold. If the speaker is returned for service, please include the original dated receipt with the product.

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 spea- ker data.

SEALED ENCLOSURES

Sealed enclosures are easy to build. The size is not critical, but it can´t 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. You can use RW15 in sealed enclosures if you use single voice coil connection.

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 spea- ker 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 spea- ker 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 it´s 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.

All DLS subwoofers works well in vented boxes.

BANDPASS ENCLOSURES

In all bandpass enclosures the speakers are hidden in- side 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 DLS subwoofers can be used in bandpass enclosures.
