The E3 HS18 subwoofer is the latest high-power subwoofer model from the E3 Audio brand, designed to replace previous popular subwoofer lines with an optimal solution for bass, power and durability.
With a 50cm diameter bass speaker, power up to 1000W, high sensitivity of 99dB and the ability to go down to 30Hz, the E3 HS18 becomes the perfect choice for professional karaoke systems, flight rooms, lounges or singing rooms with an area of over 20m².
The E3 HS18 subwoofer is not just a simple upgrade but a significant step forward in terms of power, design and sound performance. Below are the most outstanding advantages that make this product the top choice for professional karaoke systems:
The E3 HS18 subwoofer impresses with its square, sturdy and standard appearance in an industrial design style. The speaker cabinet uses high-quality MDF wood, which can eliminate unwanted resonance, helping the bass to be clean and free of background noise.
The surface is covered with scratch-resistant and moisture-proof matte black paint, ensuring durability when operating in smoky and dusty environments such as business karaoke. The front is equipped with a powder-coated metal grille, protecting the speaker from impact while optimizing sound dissipation. The blue E3 Audio logo creates an easily recognizable brand highlight.
The biggest strength of the E3 HS18 lies in its ability to reproduce low frequencies. With an 18-inch (50cm) bass speaker and a 100mm coil, the product reproduces a frequency range of 30Hz – 150Hz (±3dB), providing deep, strong, clear and energetic bass.
The high sensitivity index of 99dB shows that the sub works effectively even when paired with a medium-power main. The continuous power of 1000W and the peak SPL of 133dB Peak allow the sub to reach high sound intensity without distortion - which is essential in karaoke environments or small stages.
The E3 HS18 uses a specialized paper cone, usually only found on high-end stage speakers because it produces a softer, warmer and more natural sound than plastic or composite. The honeycomb technology of the paper cone increases mechanical strength and reduces resonance.
The suspension system and magnetic magnets are also fine-tuned to help the speaker control amplitude well, reducing distortion when operating at high intensity continuously. This is a valuable advantage in long karaoke sessions or operating in harsh environments.
As a passive subwoofer, the E3 HS18 needs to be combined with a separate power amplifier to operate. The standard impedance of 8Ω makes the speaker easy to match with many popular amplifier models. In particular, thanks to its high sensitivity, the E3 HS18 is not too "power-hungry", and can still achieve good SPL when combined with a 1000W - 1500W/channel amplifier.
The speaker works best when used with a crossover or a digital reverb with a frequency division function, which helps separate the sub frequencies and avoid overlapping with the full-range speakers. With standard settings, the product gives a feeling of "solid" bass, spreading widely and not causing rumble.
Sub E3 HS18 is not only outstanding in power and sound quality but also a choice of long-term sustainability. With good mechanical structure, impact-resistant coating, sturdy metal grille - the product maintains stable performance even after many years of continuous use.
This is an important factor for karaoke business units, when stable performance and low maintenance costs are the decisive factors for profits. At the same time, production on European standard lines helps HS18 become a highly reliable product, suitable for long-term investment orientation for professional sound systems.
E3 HS18 is a speaker line used in many sound configurations from high-end family karaoke to flight rooms, lounges or small stages. Choosing the right subwoofer not only helps improve overall sound quality but also increases the durability of the entire system. Below are the ideal spaces and purposes for this model:
To ensure the purchase of genuine E3 HS18 subwoofers, customers should choose reputable distributors with full warranty policies, technical support and practical experience at the showroom. One of the most reliable addresses today is Phuc Truong Audio - a specialized supplier of professional karaoke and stage audio equipment.
Here, customers are not only consulted on technical sound system combination, but also check the actual product quality right at the store. Phuc Truong Audio commits to 100% genuine products, good competitive prices, nationwide delivery and 12-month genuine warranty.
In addition, with a team of experienced technicians, this unit supports on-site installation, setting the sub at the correct crossover frequency, ensuring maximum bass power of the E3 HS18 in any space. This is the ideal destination if you are looking for a high-power, durable, efficient sub suitable for spaces from 20-35m² or more.
The E3 HS18 subwoofer is a passive subwoofer, meaning it does not have built-in power, but needs to be paired with a power amplifier to operate. Thanks to that, it can exert much more power than an electric subwoofer - which is limited by the integrated amplifier. With a 50cm bass design and a capacity of up to 1000W, the HS18 provides a deep, strong bass range, suitable for professional sound needs or large karaoke rooms.
This model works effectively in spaces from 20m² to 35m², especially rooms with high ceilings or using sound-absorbing materials. With a maximum SPL of up to 133dB, the HS18 sub ensures even and deep bass distribution throughout the space without losing breath or distortion.
Because it is a subwoofer, the E3 HS18 requires pairing with a power amplifier (amplifier) with a compatible output level (for example: 1000W RMS at 8Ω). In addition, to optimize the subwoofer frequency range and separate frequencies, you should use a dedicated digital reverb or crossover. This helps the subwoofer operate at the correct frequency, without being mixed with the full speaker signal, thereby increasing overall performance.
The answer is yes, if you are building a high-end home karaoke system, have a large space and want to experience powerful bass. However, you need to make sure that the system has a power amplifier large enough to pull the sub. If you use a mini system or a low-power integrated amplifier, an electric subwoofer will be more suitable.
