• use the furniture gliders of the combination feet instead of the spikes on delicate floors.

Bass attenuation – Inserting the bass absorber

• Transmission line loudspeakers are a special type of loudspeaker that use a complex cabinet design to increase the soundpressure level at low frequencies and improve the quality of the bass response. Bass attenuation using additional damping is a technique that we apply to our transmission line speakers in order to control and optimize the sound pressure in the bass range if necessary.
• The idea behind the bass attenuation is to reduce the lower bass range and thereby minimizing unwanted room resonances. These can occur if the loudspeaker is operated in a room that
  • allows standing waves due to its geometry,
  • is relatively small,
  • requires the speakers to be positioned close to the walls or in the corners, thereby increasing the bass response.
• As a result, the bass range can sound overemphasized or even unpleasant.
• Closed cabinets offer the best bass reproduction, but the sound pressure in small cabinets is too low. For this reason, various methods such as bass reflex are used to utilize the energy generated by the rear of the bass cones to amplify low frequencies.
• We have opted for the transmission line principle because it not only increases the sound pressure level at low frequencies, but also has a significantly better impulse and transient response. T+A has been developing and building Criterion speakers using precisely this principle since 1982.
• A transmission line works in a similar way to a large wind instrument or an organ pipe by generating standing waves in the long sound guide inside the cabinet, which lead to a strong additional radiation of low frequencies from the outlet opening below the woofers.
• If this is too strong for the reasons mentioned above, it is possible to reduce the bass response by 2-3 dB by inserting the bass plugs supplied into the front sound outlet openings.
• Here you can see a schematized frequency response:

Please use the supplied line port removal tools, as pictured here

1. Slide the tools as shown in the edge area of the line port through two of the holes.

2. Pull the line port forward carefully.

3. Once the line port has detached from the fastening, remove it with your fingers.

4. Squeeze the absorber slightly and tilt it backwards.

5. Insert the absorber about 5 cm (2 inches) deep into the bass tube, leaving a gap of a few centimeters between the absorber and the line port.

6. Tilt the absorber forward again and release it.

7. Once the absorber has returned to its original shape, bass reduction will be achieved.

8. The intensity of the bass reduction can be adjusted by varying the position of the absorber, for example, by inserting it diagonally or laying it flat.

9. Reinsert the line port by gently pressing on the frame on both sides of the line port.

Notice
To avoid damage, do not exert excessive pressure on the line port.

Positioning

The position of the loudspeakers is non-critical, since their radiation pattern is excellent. Provided that you keep to a few basic rules it is easy to determine the ideal position for them.

• They should be positioned in such a way that the two speakers and the listener form the three points of an approximately equilateral triangle.
• On no account set up the speakers too far apart.
• The treble and mid-range units should be set up roughly at ear level.
• Angling the speakers in towards the listener may improve the sound quality.
• The minimum listening distance is three metres (9.8 ft) and we do not recommend that you position yourself any closer to the speakers than this. To fulfil the equilateral triangle rule this implies a minimum distance between the speakers of three metres (9.8 ft).

The listening room

When positioning floor standing speakers, several factors should be taken into account in order to achieve optimum sound quality. Here are some important points that may vary depending on the conditions of the listening room:

1. Positioning in the room
   Ideally, the speakers should be positioned so that they allow for even sound distribution in the room. They should normally be arranged in a symmetrical setup to the listening position

2. Distance to the wall
   The distance between the speakers and the wall influences and enhances the bass response. As a rule, a certain distance (at least 0.5 m to 1 m/ 1.6 to 3.2 ft) should be maintained to avoid unnatural increase in the bass and low frequency range. This can vary depending on the speaker design and room conditions.

3. Distance to the listening position
   The optimum distance of the speakers from the listening position may vary depending on the size of the room and personal preferences. In a larger room, the speakers may need to be further apart to ensure good stereo reproduction.
   The special arrangement of the Criterion speakers‘ mid/high range system (Symmetric Directivity Technology) reduces reflections from ceilings, floors and walls and thus enables greater listening distances without losing the good imaging properties due to increasing indirect sound components.

4. Acoustic treatment of the room
   The acoustics of the room can have a considerable influence on the sound quality. The use of carpets, curtains or acoustic panels can help to reduce unwanted reflections and improve the sound.

5. Listening position
   The position where you usually listen to music should be taken into account.
   The speakers should be aimed at this position to ensure optimum sound quality.

6. Angle and orientation
   The speakers should normally be aimed slightly inwards or towards the listening position for more accurate stereo imaging.

7. Testing and fine-tuning
   It is important to try out different positions and settings and check the sound to find the best possible setup. Sometimes small adjustments can make big improvements.
   These guidelines can serve as a starting point, but it is important to note that the optimal placement of floor standing speakers depends heavily on the individual characteristics of the listening room and personal preferences. It may also be helpful to consider professional advice or room acoustic measurements to achieve the best possible results.

Connecting

Amplifier

• The Criterion speakers can be connected to all amplifiers designed for a load impedance of 4 ohms.
• To bring out the full acoustic potential of these speakers, we recommend load-stable power amplifiers with a high current delivery capacity >10 amps.
• In principle, an amplifier should not operate permanently at the limit of its performance, but should have sufficient power reserves. If the electrical signal exceeds the maximum power limit of the amplifier, clipping may occur. This causes the peaks of the signal to be cut off, resulting in distortion and undesirable sound.

Speaker cables

The cable that is used has a decisive influence on the sound of the overall system. T+A has therefore developed its own range of cables, which includes the right cable for every application. These cables are matched to the special properties of our loudspeakers.
All cables used should be of the same length!

Standard wiring

In the standard wiring arrangement only one speaker cable is required for each loudspeaker. The linking bridges between Bass and Mid / High must be left in place.

Bi-Wiring

Bi-wiring provides better sound by separating the bass (Bass) signal and mid- range/treble signals (Mid/High). Two speaker cables are required for each loudspeaker.
If your power amplifier has two loudspeaker outputs (A and B), the speakers are connected as shown in the illustration below; If the power amplifier has outputs for only one pair of loudspeakers, connect both cables to these outputs in parallel.

Notice
In bi-wiring arrangements the cables bridging of the woofer (Bass) and mid/high (Mid/High) input terminals must be removed

Bi-Amping

For biamping, the signal paths of the low and mid/high ranges are separated before the power amplifiers.
One stereo power amplifier takes over the amplification of the low frequency range for both channels while the other stereo power amplifier drives the mid/high frequency range of both channels.

Notice
In bi-amping arrangements the cables bridging of the woofer (Bass) and mid/high (Mid/High) input terminals must be removed

Running in the speakers

Please note that loudspeakers require a break-in period of up to 100 hours because the mechanical parts, such as membranes, suspensions and centerings run in during this time and develop optimum vibration behavior.
This break-in period improves the sound quality, as any initial tolerances are reduced and the components reach the desired final reproduction characteristics.

Protection cover

The covers included in the scope of delivery can be fitted to protect the loudspeaker drivers. The covers are acoustically optimized. For the best possible sound quality, we recommend that you remove the covers during playback.
The covers are fixed with integrated magnets.
To attach, align the covers to the edges of the housing and let them snap into place on the housing. To remove the covers, carefully pull them off towards the front.

Environmental aspects

• In the development of Criterion loudspeakers we concentrate on innovative solutions to problems, and solid, well thought-out designs, but these are not our only concerns.

• We place equal importance on the maintenance of all German and European safety norms and standards.

• We are able to guarantee that our products are of the highest quality, and meet all our specifications in full, because we carry out strict quality checking of all materials, employ painstaking production methods controlled by highly qualified staff, and carry out
  a fully automatic, computer-controlled final quality control procedure. At the earliest stage of development we also emphasise the importance of avoiding environmentally harmful materials and methods of working.

• For example, we avoid the use of materials which are injurious to health, such as chlorine-based solvents and CFCs. We also aim to avoid the use of plastics in general, and PVC in particular, in the design of our products. Instead we rely upon metals and other non-hazardous materials which are easy to recycle.

• The sound-absorbent wadding used in our loudspeakers is made of 100 % polyester fib-res, in conjunction with a binding fibre. This material has been tested for harmful ingredients to Eco-Tex Standard 100; the same test is used for clothing, bedclothes, pillows, mattresses, household textiles etc. The wadding we use has passed the test entitled ‚textiles tested for harmful materials‘ and fulfils the currently valid humane-ecological requirements. It has even successfully met the very exacting requirements of the standard test for baby clothing.

Maintenance

Notice
In order to prevent damaging the surface of the speaker,

• only wipe the surface of the speaker with a soft, dry cloth for cleaning
• never use harsh cleaning agents or solvents

The front grille can be carefully cleaned with a vacuum cleaner if necessary.
Please note that the speaker chassis of some speaker types are mounted directly be-hind the cover.
Therefore, do not press too hard against it with the vacuum cleaner to avoid damaging the sensitive speaker chassis.
