Loudspeakers should be placed so that the distance between the speakers and the speaker is approximately an equilateral triangle. The tweeter and midrange drivers should be at ear level. Turning the speakers into the room has no sound advantages.

The minimum hearing distance should not be less than 2 meters. According to the triangular rule, this results in a minimum distance of 2 meters between the loudspeakers.

Keep in mind that the bass response is increased by approx. 3 dB by positioning the speakers near to the wall and up to 6 dB in the corner of the room.

In order to avoid excessive bass radiation, it is therefore advisable to position the cabinets as freely as possible with a distance of at least 0.5 meters to the side walls.
Hiding the speakers behind furniture or curtains has an enormous effect on the height reproduction.

Smaller loudspeakers can be easily integrated into open cabinet walls or shelving systems.

In order to reduce the transmission of low frequency components to shelves or furniture elements, it is advisable to place the boxes on dampening material or spikes for acoustic decoupling.

Please note that loose furniture elements such as shelves or cupboard and glass doors are easily stimulated to resonate despite acoustic decoupling.

For this reason, ensure additional damping to avoid resonance, e. g. by gluing in felt strips or the like.

The T+A floorstanding loudspeakers can be placed on spikes to achieve a good decoupling of low frequency components from the floor.

To avoid injury, be extremely careful with the extremely pointed spikes and keep them away from children!

Your T+A loudspeaker cabinets can be operated with all amplifiers designed for a load impedance of 4 ohms. If the speakers are to be connected to an amplifier with an 8 Ohm output impedance, please check with the amplifier manufacturer whether the power amplifier can still drive 4 Ohm speakers without any problems.

There are a number of mutual interactions between amplifier and loudspeakers that require these components to be well matched to each other for a truly perfect sound experience. For this tuning, the simple question "How many watts does the amplifier need ?" is not enough. The following points should therefore be checked when selecting the amplifier!

For the output power, a distinction is made between continuous sine power and pulse power (peak power). When comparing power amplifiers, only identical power specifications should be compared.
Care should also be taken to ensure that the manufacturer specifies the output line for simultaneous operation of both channels in the case of stereo power amplifiers, since only the specification under this measurement condition corresponds to the practical operating conditions !

The T+A loudspeakers have very good efficiencies and therefore do not necessarily require extremely high continuous power. A value of approx. 50 W per channel at 4 ohms is perfectly adequate for normal listening volumes in small rooms and for small loudspeakers. For larger speakers and rooms over 30 square meters, 100 W should be available. In addition, a higher power also benefits the playback dynamics and brings more reserves for good fine detail and a detailed resolution of complex music signals.
Much more important than the numerical value of the output power is the stability of the power amplifier. Stability is critical to how well the amplifier handles phase rotations that occur when driving any loudspeaker. An amplifier's ability to deliver current is critical to its stability.
A good criterion for judging current delivery capability is the amplifier's output power at 2 ohms, which should not be less than the value at 4 ohms.
Some information about the expected stability of the amplifier is also given by its power supply. Here the size (weight) of the power transformer and the value of the filter capacity are decisive. Basically, power supplies in which this filter capacitance is divided among many smaller capacitors react more quickly than normal power supplies and can therefore still deliver correspondingly high currents even at high frequencies.

By far the most defects in loudspeakers result from overloads. Two main causes are responsible for this:

1. overdriving of the loudspeaker
Overdriving the loudspeaker is actually less critical, because when a loudspeaker reaches its load limit, it produces clearly audible distortions. In such a case, please reduce the volume to protect your speaker.

2. overdriving of the amplifier (clipping)
Clipping is the cutting off of signal peaks that an amplifier inevitably causes when overdriven. The resulting distortions of the amplifier output signal are very high in energy, but also very high in frequency. They may even be inaudible, but will destroy the connected loudspeaker within a few seconds. Basically, an amplifier with higher output power gets into the limitation later. The danger to the loudspeaker from the dreaded clipping is therefore less with amplifiers of higher power. There are a number of amplifiers that reduce the danger of clipping, e.g. by so-called "soft clipping". However, the best protection is provided by a clipping protection circuit which immediately switches off the loudspeaker output if clipping occurs, thus ensuring effective protection of the loudspeaker cabinet without any loss of sound quality. Incidentally, all T+A amplifiers feature this effective type of clipping protection circuit (Protection).

An often underestimated influence on the sound of the overall system is exerted by the cable used. T+A therefore recommends the use of high-quality cables for the loudspeaker cabinets and electronics. T+A has developed its own range of cables specifically for these applications, which includes the right cable for every application. These cables are matched to the special characteristics of our loudspeakers.

T+A recommends the Speaker Koax cable as the highest-quality variant. This is a coaxial cable with an inner conductor and two insulated, superimposed cross-braided jackets. It impresses with an exemplary attenuation curve and an extremely low inductance. Due to the technical parameters and the solid mechanical construction, an explosive, sovereign sound is achieved with thrust, bass pressure and mid-range presence.

The Speaker Six cable, which is constructed as a round conductor, consists of 6 strands that are tightly wound around a core made of PUR. Three opposite strands are connected to form a channel. Two of these three strands consist of CU / AG wires and the third of CU.

Due to its special interconnection, this cable has excellent attenuation characteristics and low resistance. This makes this cable particularly suitable for long connection lengths (up to 15 m). It is easy to configure and suitable for all speakers. Sonically, this cable impresses with agility, liveliness, cleanliness and sound color reproduction.

As a classic twin cable with particularly low resistance, the Speaker Twin 2 cable was developed. The two conductors consist of 7 strands with 18 wires. Three of these strands are made of CU / AG, the rest of CU. The conductors are extremely tightly twisted to avoid mechanical vibrations.

Due to the low resistance, this cable is more suitable for longer connections (from 5 m). The sound shows a very powerful bass as well as clear and detailed mids and highs.

Due to its very high quality insulation, it achieves a good attenuation curve with very good frequency stability. Due to its shape, this cable is also particularly suitable for cabling surround systems.

The handling of the cables can also have a great influence on the sound of the system. It is important to note a few basic things.

The highest quality is achieved with cable pieces of equal length for the right and left speaker.

Speaker cables should not be kinked or strongly pressed. When overcoming door thresholds, it is recommended to use a cable shaft, do not jam the cable in the door. Rolling up of overlong cable sections is not recommended. It is better to lay these sections in a meandering manner. Due to a different structure of coaxial cables, they can also be rolled up without adverse effects on the sound. Loudspeaker cables should never be laid near AF cables. This could lead to crosstalk. All phono (record player) cables are particularly sensitive to this.

The same cable should also be used for bi-wiring operation for the different frequency ranges.

The cables from the T+A range are suitable for the entire frequency range because of their particularly good properties. For those listeners who prefer a light and fast as well as very precise sound with a dry bass, the use of Speaker Coax is more recommended.

Those who prefer a rather softer tuning with less presence and a warm bass should use the Speaker Six cable.
