Frequently Asked Questions - INC 2602 HECO

How to install the Heco INC 2602 speaker in a plaster ceiling?

Cut a hole 198 mm in diameter. Remove the protective grille, loosen the mounting screws to place the terminals in position A. Insert the speaker into the hole then tighten the screws: the terminals pivot to position B and secure the speaker.

What type of cable to use to connect the speaker?

Use a quality speaker cable, minimum cross-section 1 mm² for less than 3 meters, or 1.5 mm² for more than 3 meters. Strip the insulation 10 to 15 mm, twist the strands and insert them into the spring terminals by pressing the head.

How to adjust treble and midrange on the speaker?

The speaker has two switches: treble and midrange. Each offers three positions: -3 dB, 0 dB and +3 dB. Adjust according to room acoustics: for a very reverberant room, choose -3 dB; for a very absorbent room, +3 dB.

Can the tweeter be angled?

Yes, the tweeter is mounted on a swivel (swivel) allowing tilt up to 35 degrees to direct sound towards the listening area.

What is the impedance of the speaker?

The speaker has an impedance of 2 x 4 ohms. It can be connected in series or parallel depending on the amplifier. Check compatibility with your amp (minimum load 4 ohms).

How to avoid damaging the speaker?

Do not push tone controls to the maximum. If you hear distortion, lower the volume immediately. Ensure the amplifier is not underpowered: a too weak amp can produce dangerous distortion.

Can I use the speaker outdoors?

No, the speaker is designed for indoor installation (wall or ceiling). It is not waterproof and does not resist humidity.

How to remove the protective grille?

For the INC 2602 model, the grille is removed by unscrewing the visible screws. On some models, it simply snaps on; pull gently.

What amplifier power is recommended?

The recommended power is 30 to 160 W per channel. The speaker handles a nominal power of 100 W and a maximum power of 180 W.

What to do in case of sound quality issues?

Check polarity: the black (-) terminals must be connected to the negative terminals of the amp, the red (+) to positive. Make sure the cables are fully inserted and the terminal screws are tightened. Also adjust the treble/midrange switches according to acoustics.

Congratulations on your fine new loudspeakers and thank you very much for choosing HECO! You have made an excellent choice. The high-quality speakers produced by HECO are renowned all over the world.

Please study the instructions and information below carefully before using your new loudspeakers.

HECO INC/INW LOUDSPEAKERS - SPECIALLY DESIGNED FOR CEILING FITTING/WALL MOUNTING

Heco INC/INW speakers have an ingenious clamping mechanism that enables you to easily fit them into a hole cut into a baffle. The easiest way is to fit them in a plaster board or similar ceiling. When using an opening in a masonry wall, a plaster or timber board is also needed. For the fitting dimensions, please see the technical data given at the end of the manual.

Removing the grille (fig. 1)

INC 802 / INC 602 / INC 2602 (fig. 2)

The clamping mechanism for attaching the speaker can be accessed after removing the protective grille. Loosen the screws and move the clamps to position A. After placing the appliance in the cut-out hole, tighten the screws. This automatically turns the clamps to position B and tightens them.

INW 802 / INW 602 (fig. 3)

After removing the protective grille first dismantle the baffle using the 6 visible cross-head screws (fig. 3.1). Loosen the screws and move the clamps to position A. After placing the appliance in the cut-out hole, tighten the screws (fig. 3.2). This automatically turns the clamps to position B and tightens them.

GENERAL INFORMATION ABOUT CONNECTING YOUR HECO LOUDSPEAKERS

Please always use a good quality loudspeaker connection cable from an audio dealer. To prevent impairment of sound quality, we recommend cables with cross-sections of at least 1 mm^2 for lengths up to 3 m and at least 1.5 mm^2 for lengths above 3 m.

Always turn off the amplifier or receiver before connecting or disconnecting loudspeaker cables. Place the loudspeakers in their planned positions and cut the cables to the right length. The cables for both channels should always be exactly the same length.

Strip 10 – 15 mm of insulation from the ends of the cables and twist the ends. The loudspeaker terminals are equipped with a clamping mechanism (fig. 4). Press the terminal head down and guide the stripped cable end into the hole on the side. On releasing the terminal head, the cable is secured, ensuring the best possible contact.

For good sound it is imperative that the cables must be connected in such a way that the speakers are “in phase”. This means that the black negative terminals on the speakers (-) must be connected to the negative (-) terminals on the amplifier, the red positive (+) speaker terminals to the positive (+) amplifier terminals. To make this easier one wire of most speaker cables is marked with a coloured strip or a ridge in the insulation.

Before switching on the system double-check all your connections and make sure that the terminal screws are tight and that there are no short circuits caused by stray wire filaments – this could cause serious damage to your amplifier!

ACOUSTIC ADAPTATION

The crossover facilitates individual sound adjustment of the speaker system via high-quality jumpers:

1. Tweeter level adjustment (treble) (fig. 5A)
2. Mid-range adjustment (midrange) (fig. 5B)

It is advisable to conduct the optimum setting according to your own personal listening preferences. We recommend the following switch positions as a basic setting for various listening areas:

Listening area Example	Switch position	„treble“	Switch position „midrange“
Low sound-absorbing setup	Wet rooms, hard reflective surfaces, tiles, large glass areas, rooms with minimal furniture	-3dB -3dB
Normal sound-absorbing setup	Carpets, glass surfaces with curtains, leather objects, rooms with a normal amount of furniture	0dB 0dB
High sound-absorbing setup	Carpets, upholstered objects, heavy curtains, rooms with lots of furniture	+3dB 0dB

The tweeter's „swivel“ technology allows it to be pivoted by up to 35 degrees, thereby enabling ideal sound dispersion and perfect alignment to the listening area:

HOW TO AVOID DAMAGE TO YOUR VALUABLE SPEAKERS

All HECO loudspeakers are designed and built for optimum sound reproduction with the tone controls in the central position – i.e. with “linear” amplifier output. Turning up the bass and treble controls too far delivers more power to the woofers and/or tweeters, and at high volumes this can actually destroy the speaker units!

If the output of your amplifier is significantly higher than the rated power handling capacity of your speakers extremely high volumes can physically destroy your speakers. This doesn't actually happen often but you should be aware that it is possible.

Weak amplifiers with low output ratings can actually be more dangerous for your speakers at medium volumes because weak amplifiers may overload much faster than powerful ones and this causes measurable and audible distortion, which is extremely dangerous to your loudspeakers.

Always turn the volume down immediately as soon as you hear distortion! If you like listening to loud music make sure that your amplifier can deliver at least as much power as the speakers' power-handling rating.

Amplifiers, tuners and CD/DVD players can all produce inaudible high-frequency signals – and this doesn't only apply to cheap products. If your tweeters fail at low or medium volumes you should have a qualified technician check your system components for dangerous inaudible signals.
