Rugged, rugged design with a 32mm voice coil attached to a steel spider
Pre-applied 3M VHB adhesive for fast, safe installation
Rare neodymium earth motor and proprietary two-layer voice coil
4 ohm impedance for use with small class D amplifiers
40 watts RMS load capacity for high power
Product details
The speaker we use is built to turn large, thick, rigid surfaces into speakers. The 32mm voice coil is attached to a steel spider for maximum restoring power when high amounts of force are applied, making it perfect for large glass panes, furniture and surfaces that would normally withstand the effects of an exciter.
A neodymium magnet is used to create maximum magnetic flux around its own voice coil for greater sensitivity compared to similarly sized exciters. This, in turn, reduces power requirements and makes it possible to use very small Class D audio amplifiers without sacrificing overall output.
To ensure maximum acoustic energy transfer between the transducer and the surface it is attached to, 3M Very High Bond (VHB) adhesive is pre-applied to the main body ... just peel and stick! For quick electrical connection, two male quick disconnect spade terminals are built into the housing.

| 1. How did the speaker come about? |
| The advent of the speaker is intertwined with a number of leading inventions that took place in the 19th century. You can think of the telephone, phonograph and gramophone. The inventor Graham Bell discovered at the end of the 19th century that sounds are created when you vibrate a membrane. These vibrations are converted into sound, which formed the basis for many devices that we use every day. |

| 2. How exactly does a speaker work? |
| A speaker, also called loudspeaker or box, consists of various parts that are jointly responsible for converting electronic signals into sound. The signal from an amplifier is converted into sound waves, when these sound waves reach the ears, the eardrum starts to vibrate. These vibrations are converted by the hearing organ into signals that go to the brain. The brain interprets the vibrations and converts it into the sound we hear. |

| 3. The speaker cabinet |
| First of all, the speaker cabinet naturally offers protection, because all parts are well stored, which greatly reduces the risk of damage. What many people do not know is that the cabinet is also partly responsible for the quality of the sound. The speaker cabinet prevents acoustic short circuits. Acoustic short-circuiting occurs when the air at the front of the cone and at the back of the cone communicate directly with each other. |

| 4. The tweeter |
| If you've already done some research, you've probably come across the word tweeter on a regular basis. The tweeter is responsible for reproducing high tones. A tweeter generally reaches a frequency of 2000 to 20,000 Hz, which can be heard by the human ear. Incidentally, it is the case that with hearing damage or with aging, the high tones are often no longer (properly) heard. |

| 5. Wattage of a speaker what does that say? |
| Wattage is always a tricky topic. This is because manufacturers use different ways to calculate wattage. Most people are under the assumption that a box with a high wattage can also automatically increase the speed. However, the maximum volume does not only depend on the wattage, there are a number of parts that play an important role in this, such as the sensitivity and quality of a box. |

| 6. What format do I need? |
| A question that is asked regularly, unfortunately it is not so easy to answer. It depends on what you want to use the speaker for. Are you going to throw a party at home? Then you can opt for a somewhat larger format. The smaller boxes are suitable for background music or music with a lower volume. |

| 7. What is a woofer? |
| The woofer is (often) the bottom (and largest) speaker on the front of a speaker. The woofer is responsible for reproducing sound with low tones. The size of a woofer determines how well it is able to reproduce lower tones because a larger woofer can move more air and thus ensure a higher sound pressure. In short, the larger the woofer, the better the speaker is able to reproduce low tones. We also call these low tones the bass. Coming back to the speaker cabinet: the speaker cabinet produces, for example, a nice bass from the woofer of your speaker. If you would keep the same woofer in the air without a speaker cabinet around it, there would be no bass at all and the sound quality would also be very poor. |

| 8. What is the cone? |
| The cone is an important part of a woofer. This visible part (often behind a grille or grille) is responsible for moving air, which ultimately results in sound waves. In the middle of the cone you will find the dust cap. This is often a kind of bubble. The dust cap ensures, as the name suggests, that no dust can get into the woofer. In fact, it protects the internal parts of a speaker such as the coil. |

| 9. When is a speaker used? |
| You can actually answer this question yourself, because you come into contact with it every day. Wherever you are, a loudspeaker is always used somewhere. For example, they provide you with background music when you are in a waiting room, during a party or presentation and even on the terrace. But other devices that you may not easily think of also have a speaker. How about your telephone or (in miniature) the earplugs of your MP3 player? |
