Manual DLS Ultimate UR 2.5 Car Speaker

Manual

Welcome

Thank you for buying a DLS Ultimate speaker.

This manual will show you how to do a correct installation. Please

read the entire manual before beginning the installation. Install

the speakers yourself if you feel confident with our instructions

and if you have the proper tools. The ULTIMATE speakers are

our best speaker line but a poor installation job can destroy the

final result even from these speakers. So if you feel unsure,

turn over the installation job to someone better suited to it.

Installation

The speakers should be installed high up in the door side or in

the dashboard. These speakers doesn’t require any box.

When the midrange is mounted high up on the dashboard the

mid level creates a frequency peak in some vehicles. If so use

the low ”mid level” in the filter box. If the level is still too high,

connect a 3-5 ohm resistor in series with the + feed. We

recommend you to install them in a strong baffle of MDF-

board or similar. A strong baffle will improve the sound quality.

If you don’t have the possibility of doing strong baffles you

must use the steel rings coming with the drivers to improve

the stability of the mounting.

Wiring

Use high quality speaker cables like DLS HQS or similar.

Avoid using the factory pre-installed cabling, they will not give

the sound reproduction that you should expect from these

high class speakers.

Make sure the cables don’t get jammed causing a short circuit

to ground. This can damage the output circuits of your head

unit or amplifier.

Connect the cables with correct polarity to the speakers.

Observe the markings on the terminals. The red marked

terminal is plus and the black is minus.

Break-in period

Allow the speakers to play at normal volume for at least 15-20

hours. After this time the performance is correct.

Crossover

The speakers must be used with either a passive or an active

filter in a 3-way configuration. If you can’t use active filters you

can build your own passive filter like in this example. It is a 6/6

dB slope band pass filter ~500 - 4500 Hz

This rather simple passive filter can be used for UP2.5 / UR2.5.

Iridium 3 should only be used in active crossover mode. Use

polypropylene capacitor and low-resistance air coil. The resistor

is used to adjust the level. The 4,7 omhs is a standard value

but you must find a resistor value that matches the sensitivity

of the other speakers in your system. In some configurations

you don’t have to use a resistor at all.
