The irreplaceable companion of the full-band speakers-a brief analysis of the role of ultra-low speakers
The sound box is the terminal of the entire sound system and an extremely important part of the sound system. Its function is to convert the audio electrical energy into the corresponding sound energy and radiate it into the space to convert the electrical signal into an acoustic signal to make people's ear Hear directly.
Audio equipment is divided according to the audio frequency, and can be divided into full-band speakers, subwoofer speakers and ultra-low speakers.
The so-called full-band speaker refers to the sound that can cover the low frequency, middle frequency and high frequency range. Bass speakers and subwoofers are generally dedicated speakers used to supplement the low-frequency and ultra-low-frequency playback of full-band speakers. This type of speaker is generally used in large and medium-sized sound systems to enhance the strength and shock of low-frequency playback. When in use, most of them are divided by an electronic crossover (crossover), and the low frequency signal is sent to a special bass amplifier, and then the bass or subwoofer speakers are pushed.
The subwoofer is small and compact, with its own amplifier and filter in the box, no additional requirements for the system. The system has a subwoofer that specifically reproduces bass, and other channels can use smaller speakers. The configuration and use of the entire system are more flexible and convenient. Generally speaking, the creation of bass requires the use of larger speakers, but as long as a pair of ordinary small speakers are placed on the side of the wall, it is enough to dive the replayed sound into the mid-bass range.
T30 dual 15 inch subwoofer
The Beilarly T30 subwoofer adopts a hybrid structure and combines the design concept of a bass inverting system. It has the characteristics of high efficiency, long range, low lower frequency, etc. The entire sound field is coupled through the entire front plane, so it can happen normally Air friction distortion and current distortion are minimized, energy is efficiently transferred, controllable pulses are generated, and optimal dynamics are obtained. With a compact design, the box structure is small and light, but the energy emitted is amazing.
S-18 + single 18 inch subwoofer
S-18 + is a subwoofer with a flat direct-shooting design. It is flexible, powerful, and has a wide dynamic range at low frequencies. It adopts a rectangular box with 18 centimetres and 13 layers of glue. The polyester black pearl paint on the surface achieves the functions of waterproof, sun protection, wear resistance, protection and modification. The high-power speaker design can better meet the uniformity and sound pressure level of the sound field. At the same time, it is recommended that users choose 8 ohm / 1000W power amplifier to match the use, so that the S-18 + is more powerful and exerts the best results.
ES218 dual 18 inch subwoofer
ES218 is a newly designed subwoofer. The ultra-compact cabinet design greatly reduces the space occupation. The special cabinet structure makes the low frequency flexible, strong, and has a large dynamic range. The rectangular cabinet is made of 18% birch wood with a surface Ester black pearl lacquer achieves the functions of waterproof, sun protection, wear resistance, protection and modification.
HP-218 dual 18 inch subwoofer
HP-218 is a newly designed subwoofer with low frequency flexibility, strong, and large dynamic range. The rectangular box is made of 18 centimeter birch wood board, and the surface is polyester black pearl lacquer to achieve the functions of waterproof, sun protection, wear resistance, protection and modification. The design of the high-power speaker can better meet the uniformity and sound pressure level of the sound field. At the same time, it is recommended that users choose a 4 ohm / 1200W power amplifier to match the use, so that the HP-218 is more powerful and exerts the best results.
S-218 + dual 18-inch ultra-low speakers
S-218 + is a subwoofer with a flat direct-fire design. It is flexible, powerful, and has a wide dynamic range at low frequencies. It adopts a rectangular box with 18 centimetres and 13 layers of glue. The polyester black pearl dot paint on the surface achieves the functions of waterproof, sun protection, wear resistance, protection and modification. The high-power speaker design can better meet the uniformity and sound pressure level of the sound field. At the same time, it is recommended that users use 8 ohm / 1300W power amplifier to match the use, so that the S-218 + is more powerful and exerts the best results.
QSC-218 Dual 18 inch subwoofer
QSC-218 is a subwoofer with high sound pressure level output. Two custom built-in PA18-inch high-power woofer units provide powerful bass thrust. The special cabinet structure makes the low-frequency flexible, powerful and dynamic range. A rectangular box of 18% birch wood is used, with black pearl paint on the surface to achieve the effects of waterproof, sun protection, wear resistance, protection and modification.
