UNPACKING

Be careful not to damage the contents when you unpack the parts. Depending on which DALI RUBIKORE model you have bought, dierent accessories come with the loudspeaker. Check that all parts are contained in the cardboard box (see Table 1). Keep the packaging materials in case your loudspeakers need to be relocated or serviced.
2.1 GRILLES
The loudspeakers are delivered with the grille fronts already mounted when you unpack them. If you wish to remove the grille front, loosen it by gradually tugging at the pins that hold it in place. It is important that all pins are loosened evenly before removing the grille. Otherwise the grille may be damaged.
POSITIONING
To achieve the best results, the loudspeaker setup should be symmetrical around your favourite listening position, (see Figures 1A – 1C). We recommend that you experiment with the positions of your loudspeakers – the sound quality will change depending on the loudspeaker position. For DALI RUBIKORE 2, RUBIKORE CINEMA and RUBIKORE ON-WALL, the loudspeakers should ideally be positioned so that the tweeters are approximately at ear height when seated in your favourite listening position. DALI RUBIKORE 6 and 8 are designed as ﬂoor standing loudspeakers. They should be positioned at least 20 cm (8 inches) from the rear wall. DALI RUBIKORE 2 and RUBIKORE CINEMA should likewise be positioned at least 20 cm (8 inches) from the rear wall. DALI RUBIKORE ON-WALL is optimised for wall-mounting, but will also work well on a shelf. If mounted on a wall, there should be at least 10 cm (4 inches) from any surface underneath the loudspeaker, and if placed on a shelf there should be at least 10 cm (4 inches) distance from the wall.
Objects placed between the loudspeakers and the listening position might negatively apect sound quality. All DALI RUBIKORE loudspeakers are designed to follow our wide dispersion principle, so they should not be angled towards the listening position, but be positioned parallel with the rear wall (see Figure 2). Parallel positioning reduces distortion in the main listening area and improves room integration. The wide dispersion principle also ensures that the sound is spread evenly within a large area in the listening room.
3.1 DALI RUBIKORE 6 and 8
These loudspeakers are designed to stand on the ﬂoor, using the supplied Premium Spike Set or rubber bumpers under the loudspeakers (see Figures 3 and 4). Be careful not to overtighten the contra nuts. Spikes or rubber bumpers can improve the sound quality. You can try both to hear what gives the best sound quality in your setup. Please note that spikes may damage the ﬂoor if it is not protected.
NOTE: On some ﬂoors and in some rooms, the use of spikes is a crucial aspect in obtaining the best result. The spikes (included) should be fastened loosely in the aluminium feet, leaving the spikes’ nuts only slightly tightened. Using the screws, mount the aluminium feet in the threaded holes on the bottom of the loudspeaker.
Push the feet against the loudspeaker cabinet before tightening the screws. Place the loudspeaker with the mounted spikes upright on the ﬂoor, so that it stands steadily without rocking. Tighten the nuts, so that the four spikes sit tightly in the aluminium feet. These assembly and setup steps ensure stable mechanical coupling to the surface beneath (see Figure 3).
3.2 DALI RUBIKORE 2
DALI RUBIKORE 2 is optimised for stand mounting, but will also work well on a shelf.
If positioned on a stand or shelf, the enclosed bumpers can be placed under the loudspeaker for stable and vibration-free positioning (see Figure 4).
For the best possible sound, we recommend placing the loudspeakers with the tweeter modules at approximately the same height as your ears when you are seated in your favourite listening position.
3.3 DALI RUBIKORE ON-WALL and RUBIKORE CINEM A
DALI RUBIKORE ON-WALL is optimised for wall-mounting (see Figure 5) but can also be used on a shelf or on a TV furniture. DALI RUBIKORE ON-WALL can be used as a let, right, centre or surround loudspeaker in either horizontal or vertical position. The rotatable DALI Hybrid Tweeter allows the RUBIKORE CINEMA and RUBIKORE ON-WALL to be installed in either horizontal or vertical orientation, making it possible to use the exact same loudspeaker for front and centre applications – just like in the mixing studio.
The Hybrid Tweeter module should be rotated so that the planar tweeter unit stays vertical (upright), which is important to preserve the wide horizontal dispersion and ﬁne detail of the high frequencies.
The RUBIKORE CINEMA is designed for home theatre front and centre channel roles, either stand mounted or sitting on a shelf.
Your authorised dealer or service facility can help rotate the Hybrid Tweeter for you.
To remove the Hybrid Tweeter module from the loudspeaker cabinet, use a 3 mm Allen key (not included) to remove the four screws. When disassembled, rotate the Hybrid Tweeter by 90 degrees.
Insert the rotated Hybrid Tweeter and install it using the four screws (Figure 7). Be careful not to overtighten the screws when reassembling the loudspeaker.
If positioned on a shelf or TV furniture, the enclosed bumpers can be placed under the loudspeaker (in both the vertical or horizontal position) for stable and vibrationfree positioning (see Figure 4).
The DALI logo on the front grille can be rotated by litting it up slightly and rotating it into the desired position (see Figure 6).

CONNECTIONS

Correct, tight connections to your ampliﬁer are extremely important for your listening experience. Always use cables of the same type and preferably the same length for the left and right channels. We recommend using DALI CONNECT loudspeaker cable, available from your dealer.
Correct polarity is a detail that is often overlooked when connecting loudspeakers.
The red (+) terminal of the ampliﬁer must be connected to the red (+) terminal of the loudspeaker. The black (-) terminal of the ampliﬁer must be connected to the black (-) terminal of the loudspeaker (see Figure 9A). In a stereo or surround installation, even a single loudspeaker connected in reverse polarity will make the bass weaker and the stereo image unfocused.
For the optimal listening experience, the right loudspeaker (as seen from the listening position) must be connected to the ampliﬁer output terminals marked “R” or “Right”.
The leat loudspeaker must be connected to the ampliﬁer output terminals marked “L” or “Left”.
NOTE: Before connecting cables or changing any connections, ALWAYS turn of your ampliﬁer.
NOTE: Make sure that bare conductors are tightly gripped by the terminals with no loose wires that could cause a short circuit and damage the ampliﬁer (see Figure 8).
NOTE: If you are using DALI RUBIKORE in a surround system, follow the instructions included with your surround ampliﬁer.
4.1 SINGLE-WIRING versus BI-WIRING/BI-AMPING
All DALI RUBIKORE loudspeakers can be connected using a single loudspeaker cable (see Figures 9A and 9B). However, DALI RUBIKORE 2, 6 and 8 are equipped with two pairs of terminals, allowing you the option of running two sets of cables to each loudspeaker. The top terminal pair is internally connected to the crossover network’s high frequency section. The bottom terminal pair is internally connected to the crossover network’s bass section.
NOTE: When bi-wiring or bi-amping, ALWAYS remove the metal jumpers between the terminals before connecting cables (see Figures 9C and 9D).
For bi-wiring, connect two sets of loudspeaker cables, one to the top terminals and one to the bottom terminals of the loudspeakers. At the ampliﬁer end, connect both sets of loudspeaker cables to the same pair of terminals on the ampliﬁer (see Figure 9C).
For bi-amping, connect two sets of loudspeaker cables, one to the top terminals and one to the bottom terminals of the loudspeakers. At the ampliﬁer end, connect one set of loudspeaker cables to one ampliﬁer, and connect the other set of cables to the second ampliﬁer (see Figure 9D).

RUNNINGIN

Like any mechanical system, a loudspeaker requires a “running-in” period to perform at its best. You will experience a gradual increase in sound quality during the ﬁrst period of use. The break-in period will vary depending on use and playback volume. You should expect up to 100 hours of playback until maximum performance is reached.
Unlike other mechanical systems, the life span of a loudspeaker is increased by normal, regular playback of music.

CLEANING & MA I NTENANCE

If the loudspeaker cabinets are dirty, wipe them with a damp and well-wrung soft cloth.
Avoid touching the loudspeaker cones, as they are very fragile. If the cones need cleaning, use only a dry, soft cloth and be very careful. Avoid touching the tweeter domes. The loudspeaker grilles can be cleaned with a clothes brush and wiped with a well wrung, lint-free cloth and mild all-purpose cleaner.

6.1 AVOID DIRECT SUNLIGHT
The surfaces of the loudspeakers may fade or become discoloured over time when exposed to direct sunlight. Therefore avoid positioning the loudspeakers in direct sunlight.

DISPOSAL

If you want to dispose of this product, do not mix it with general household waste.
There is a separate collection system for used electronic products in accordance with legislation that requires proper treatment, recovery and recycling. Private households in the EU member states, Switzerland, Liechtenstein and Norway may return their used electronic products free of charge to designated collection facilities or to a retailer (if you purchase a similar new one). If you reside in countries not mentioned above, please contact your local authorities for the correct method of disposal. By following this process, you will ensure that your disposed product undergoes the necessary treatment, recovery and recycling and thus prevent potential negative efects on the environment and human health.

POWER AND SOUND PRESSURE

How loud a loudspeaker can play and still sound good depends entirely on the signal it has to reproduce. This means that it is not possible to deﬁne a speciﬁc signal level to use when comparing different speakers.
Processing a pure, undistorted signal from a powerful ampliﬁer is easier than processing a distorted signal from a low-power ampliﬁer pushed beyond its capacity.
The signal from a distorting (clipping) ampliﬁer contains much more high- frequency information than an undistorted signal, and therefore puts a heavy strain on the tweeters. As a result, loudspeakers are often damaged by low- power ampliﬁers that are forced to work too hard – and very rarely by powerful ampliﬁers, which are practically running idle most of the time.
It is also worth noting that turning tone controls on your ampliﬁer above the neutral setting signiﬁcantly burdens both loudspeakers and ampliﬁer. On a good sound system, tone controls should only be used to compensate for poor recordings and not to permanently compensate for weaknesses elsewhere in the system.
For this reason, DALI recommends that the tone controls are generally set to the neutral position. You can achieve your desired sound image by positioning the loudspeakers correctly. Keep the volume low enough to keep the sound clear and undistorted. This will minimise the load on the speakers and ampliﬁer.
All DALI loudspeakers are designed with linear impedance for an optimal ampliﬁer load. The result is a signiﬁcantly more open and detailed sonic image.

THE LISTENING ROOM

Every room has its own distinctive acoustics. These affect the way we experience sound from a loudspeaker. The sound you hear is made up of direct sound from the loudspeakers and reﬂected sound from the ﬂoor, ceiling and walls. The laft er affects the way you experience the sound. As a general rule, try to avoid large, hard, reﬂective surfaces in the immediate vicinity of your loudspeakers, as these tend to cause strong reﬂections that can affect the accuracy and spaciousness of the sound reproduction. Reﬂections can be reduced by placing a plant between the loudspeaker and the reﬂective surface. Soft objects such as carpets, curtains, etc.
may help if the sound is too bright. The amount and quality of deep bass depend on the size and shape of the room and the position of the loudspeakers. Placing the loudspeakers close to a side or back wall will emphasise the bass. Placing them in corners will accentuate the bass even more, but will also increase reﬂections.

SAFETY PRECAUTIONS

Always follow all safety guidelines.
DALI RUBIKORE loudspeakers are intended for indoor use.
The loudspeakers must only be used indoors and never in extreme hot or cold temperatures.
DALI RUBIKORE loudspeakers must not be exposed to direct sunlight.
Power of the ampliﬁer when connecting the loudspeaker cables to the loudspeaker and the ampliﬁer.
Extended use of loudspeakers at high volume levels may cause hearing damage. Do not raise the volume beyond comfortable levels.

TECHNICAL SPECIFICATIONS

In Table 2 you will ﬁnd the most common speciﬁcations for our loudspeakers.
Please keep in mind that there are countless methods for measuring loudspeakers.
However, none of them tell you anything useful about how a loudspeaker really sounds. Only your ears can decide whether one loudspeaker sounds better than another. Like all our loudspeakers, the DALI RUBIKORE series is designed to reproduce music as honestly as possible.
Enjoy your new DALI RUBIKORE!
