2 Contents Introduction Congratulations on your purchase of the Competition Pro TL-1121 subwoofer. After huge amounts of careful and detailed research, design, development and testing, TheLoudest.com proudly present this stunning subwoofer packed with revolutionary features using state of the art components and materials. Page Introduction... 2 Features... 3 Technology... 3 Configuration... 4 Enclosures... 6 Calibration... 7 Mounting Instructions... 7 Safety... 8 Troubleshooting... 9 Technical Specifications The Competition Pro TL-1121 is a 12" competition grade heavy-duty subwoofer designed to pound out deep, ultra low sub-bass which is nothing short of accurate in definition. The TL subwoofer has a durable, precision-engineered, robust build that offers fantastic bass reproduction, and maintains such clear bass reproduction at uncompromisingly high power levels. For every day-listening, installing the TL-1121 in a sealed enclosure (such as TL-1120) will result in high fidelity reproduction over the entire bass frequency range, suited to most types of music, giving audiophile quality sound. For extreme listening or SPL competitions, installing the TL-1121 in a ported enclosure (or simply removing the plug on the TL-1120 enclosure) unlocks the full potential of the woofer, resulting in pure subsonic power of monstrous proportions, ensuring the TL-1121 hits the hardest, deepest and loudest bass, blowing away just about anything that dares to stand in its path. It is imperative that you read through this manual before installing and operating the subwoofer. This will ensure correct configuration and operation. While this manual details generally how to install the subwoofer, if you do not have sufficient experience or tools, it is best to have it professionally installed. This subwoofer functions best in a system with a good quality source unit. Connecting it up to a system which includes a poor quality source unit (such as a standard, factory fitted one) may not give good results. The input power handling of the TL-1121 is 3,000 watts max. (1,000w RMS). The amplifier used to power the TL-1121 (the TL-1023 is recommended) can draw very large currents from the vehicle battery and alternator. Depending on vehicle model, one or more of these components may have to be replaced to enable the amplifier to operate to its full potential. For further details regarding this, please refer to the amplifier manual. TheLoudest.com accepts no liability for any damage resulting to vehicle components when installing or operating the TL-1121 subwoofer. It is the sole responsibility of the user to follow these instructions carefully and upgrade any vehicle components as required. Again, if you do not have sufficient experience or tools, it is best to have the unit professionally installed. Keep this manual in a safe place so it is accessible for future reference.

Technology The TL-1121 subwoofer boasts extraordinarily high cone excursion with extreme linearity and a simultaneous super-efficient heat discharge system. An overview of some of the innovative, cutting edge patent pending theloudest.com technology implemented in this subwoofer is as follows: Symmetrical Magnetic Drive (SMD). Focuses on a unique piston technique that generates immense momentum drive, far greater than conventional designs. Direct coupling advanced layer bonding (DECAL). Generates superior strength magnetic flux from the magnet to the voice coils, relentlessly delivering huge amounts of power. A specially extended top plate layer draws and directs the optimum strength of magnetic flux from the magnet to the voice coil. Subsequently, the internal pole piece draws and concentrates the flux from across the air gap to the back plate, as a result, depositing immense flux in the lower air gap plate. There are three layers that make up the complete DECAL structure, each possesses a high permeability of magnetic flux. The upper and lower layers double up as efficient heat dispersers as well as generating flux. The thicker centre layer is where magnetic energy flow is maximised. Configuration The TL-1121 subwoofer comes with dual 2 ohm voice coils. This enables the user/installer to connect one TL-1121 subwoofer to an amplifier in either of the following two ways: 1. Parallel Recommended (See fig. 1 below). - Connect the negative terminal of the amplifier to both the negative terminals of the subwoofer. - Connect the positive terminal of the amplifier to both positive terminals of the subwoofer. Connecting the TL ohm voice coils in parallel like this gives a load of 1 ohm to the amplifier. The maximum output of the amplifier at 1 ohm should be around 3,000w max and 1,000w RMS but no more. The Competition Pro TL-1023 Class D Monoblock Subwoofer Amplifier (3,000w max and 1,000w 1 ohm) is strongly recommended. 2. Series Not Recommended (See fig. 2 below). - Connect the negative terminal of the amplifier to the negative terminal of one of the voice coils (left one for example). - Connect the positive terminal of that voice coil (left) to the negative terminal of the other voice coil (right). - Connect the positive terminal of the amplifier to the positive terminal of that voice coil (right). Connecting the TL ohm voice coils in series like this gives a load of 4 ohm to the amplifier. This is not normally favourable as the parallel configuration gives a lower load impedance, getting more from the amplifier. If mounting the woofer outside the enclosure, pointing in, the connections will be made straight to the amplifier. If mounting the woofer inside the enclosure, the connections will be made via the terminal block on the side of the subwoofer box. The Competition Pro TL1120 enclosure is recommended, as it has been manufactured to match the TL-1121 and allow the woofer to perform to its full potential. Airborne Heat Relief System (AHERS). Efficiently transfers and dissipates heat to the outer massive heat-sink. This allows the voice coils to consume more heat energy and to ultimately reproduce more power. As the predominant force resulting from the symmetry pushes the woofer up, further momentum is gained at the lower air gap plate in driving the cone back down to its original position. When driven like this to full potential, in conventional woofers, the output is quickly capped as the woofer is strangled by accumulated heat in the air gap and voice coils. In the TL-1121 though, the DECAL and AHERS systems ensure that this doesn t happen. Heat is efficiently dispersed out through the upper and lower DECAL layers to the massive outer heat sink chassis fast enough to allow more current to pass through the coils again. The AHERS allows more cool air to replace the warm air through the entire vented pole piece. These two systems alone enable the woofer to consume extraordinarily higher amounts of current, therefore allowing the woofer to perform to uncompromisingly high SPL levels.

4 When connecting two TL-1121 subwoofers together, the user/installer can connect the subwoofers to an amplifier in either of the following two ways: 1. Parallel-Series (See fig. 3 below). - Connect the negative terminal of the amplifier to the negative terminal of the left voice coil of each subwoofer. - Connect the positive terminal of the amplifier to the positive terminal of the right voice coil of each subwoofer. - For each woofer, connect the positive terminal of the left voice coil to the negative terminal of the right voice coil. 2. Series-Parallel (See fig. 4 below). - Connect the negative terminal of the amplifier to both the negative terminals of the first subwoofer. - Connect the positive terminal of the amplifier to both the positive terminals of the second subwoofer. - Connect the positive terminals of the first woofer together. - Connect the negative terminals of the second woofer together. - Connect the two above connections to each other. Enclosures There are two main types of enclosure to choose from when installing the TL-1121; sealed or ported. Sealed enclosure (See fig. 5 below). A sealed enclosure gives a tighter, more punchy response, over the whole bass region. This is recommended for every-day listening as it works well with most types of music. This enclosure design gives best overall frequency response and certainly is recommended for users preferring SQ (sound quality) to SPL (sound pressure level). Ported Enclosure (See fig. 6 below). A ported enclosure gives significantly more SPL, however, this is concentrated on a smaller band of bass frequencies. This is recommended for SPL competitions and for music genres such as rap, hip-hop, r&b, drum&bass, or other bass-heavy music. Connecting two TL-1121 subwoofers to an amplifier in either of the above two methods gives a load of 2 ohm to the amplifier. The recommended way to do this is to use two Competition Pro TL-1023 Class D Monoblock Subwoofer Amplifiers (6,000w max and 2,000w 2 ohm when combined in bridge mode). The only difference between the above two methods is the way in which they are connected, simply choose which one can be most easily implemented in your situation. If mounting the woofers outside the enclosures, pointing in, the connections can be made straight to the amplifier. If mounting the woofers inside the enclosures, the connections will be made via the terminal block on the side of the enclosure. With either method of mounting, it is recommended that the terminal blocks on the side of the enclosure are utilised to make the connection to the amplifier easier. Please refer to the manual supplied with the enclosures for further information on connecting the amplifier to the subwoofers through the terminal blocks on the side of the enclosure.

TheLoudest.com manufacture a black vinyl covered enclosure, Competition Pro TL This has been designed and fine tuned to the TL-1121 subwoofer in order to achieve the best SPL and SQ. The TL-1120 is the first production enclosure that has a removable plug over the port. This revolutionary feature allows the user to swap between sealed design and ported design. For every-day listening, the plug can be installed, so the sealed enclosure design is utilised, and for SPL competitions, the plug can be removed. Other features of the tailor-made TL-1120 include the extended design, allowing enough mounting depth for the woofer, and the unit being substantially re-enforced to allow the mounting of the heavy TL-1121 subwoofer either facing in towards the enclosure, or inside the enclosure facing out. Fig. 3 Two TL-1121 subwoofers connected in parallel-series, giving 2 ohm load to amplifier. Two TL-1023 amplifiers are recommended. Fig. 4 Two TL-1121 subwoofers connected in series-parallel, giving 2 ohm load to amplifier. Two TL-1023 amplifiers are recommended. Constructing a custom enclosure for the TL-1121 subwoofer is only recommended for seasoned professionals. If this is the case, the minimum sealed enclosure volume should be 1.2 ft³ with the recommended sealed enclosure volume being 2.2 ft³. The minimum ported enclosure volume should be 1.5 ft³, with the recommended ported enclosure volume being 2.2 ft³. Installing the TL-1121 into an enclosure that is smaller than the minimum volumes specified means that subwoofer will not work to its full potential and can be placed under a lot of stress which could result in permanent damage. The TL-1121 subwoofer can be installed as part of club/pa systems by professionals.

5 Calibration Safety How to calibrate the amplifier and subwoofer with the source unit: Health Warning 1. Turn the gain knob on the amplifier all the way down The Competition Pro range of car audio is built for very high power handling. Listening to 2.

If any equalisation changes are made, repeat stages 1 to 7 until satisfied the road, including your ability to hear your own, and other vehicles. We recommend 8. Never exceed the source unit gain that you used to calibrate the system listening at low or moderate levels while driving. TheLoudest.com accepts no liability for injury, property damage or otherwise resulting Remember: from the use or misuse of this equipment. - It is possible for the gain knob to be at only a quarter of its maximum, but the amplifier is actually outputting to its full potential. This could be because the source Do not use any chemicals when cleaning this equipment. Please use a clean dry cloth. unit is supplying slightly more power than normally expected. - Always turn the gain down or off if you can hear distortion. Do not install this unit outside the car, or anywhere where it could become damp or humid, - No matter how robust or powerful a subwoofer is designed to be, any speaker s or where it can become exposed to the sun. It should be installed in a dry and ventilated mechanical structure is physically susceptible to damage if played for a prolonged area inside the car. period of time in an over-driven state. To avoid this, never use an amplifier which has RMS output values in excess of the rated RMS input values of the subwoofer or Never connect or disconnect the subwoofer when the amplifier is on; this can permanently combination of subwoofers. damage the subwoofer. Always do this when it is off. - Always ensure that the load impedance (in ohms) provided by the subwoofer is never lower than the minimum load impedance (in ohms) of the amplifier. Connecting a 1 Never open the amplifier up. Doing so would put you at risk of an electric shock. None of ohm load to an amplifier that has a minimum load of 4 ohm bridge for example, can the internal parts are serviceable by the user. In the case of the unit needing repair or result in permanent damage to the amplifier and/or subwoofer. maintenance, please take it to a qualified professional. - Avoid using amplifiers that have significantly lower RMS output values than the RMS input rating of the subwoofer. This can result in the amplifier producing distortion as it is being worked very hard. This means that the audio is distorted before it reaches the subwoofer and can damage the subwoofer permanently. Mounting Instructions As illustrated to the right of this text, the TL-1121 subwoofer can be mounted either inside the enclosure facing outwards (top diagram) or outside the enclosure facing inwards (bottom diagram). Position the woofer in place and mark the position of the mounting 8 points onto the enclosure. It is advisable to use a 1 or 2 mm drill bit to make pilot holes before replacing the woofer and using self-tapping screws (not supplied) to secure the woofer in place. If mounting the woofer inside the box, it is important to ensure the audio leads are connected to the woofer before securing it in place.
