Single 18" Active Subwoofer Speaker

β3 VR118SUBa Speaker is one of the VEYRON series speaker with a new shape structure and a new surface painting process to form a low frequency speaker. It consists of a low-frequency unit and a amplifier module. The bass unit uses the 100mm diameter high power voice coil, the voice coil uses the round copper wire, and outer wrapping method,the voice coil skeleton uses the very high strength AL material, not only strengthens the sound coil strength, but also increases the voice coil power bearing ability. 

When installed on this speaker, the rated power can reach 450W.

The design of the symmetrical magnetic circuit reduces the odd harmonic distortion of the low frequency , which fully meets the human demands for the low frequency sound quality.

VR118 SUBa is made of 18mm thick laminate, its special wooden wedge box structure, the whole speaker does not use a nail. Surface polyurethane paint has a strong resistance to wear. The tensile strength of the cabinet itself can reach 4500N.The speaker cabinet has a special bracket that can be used in conjunction with VR110. The speaker grill is made of Q235, the surface is sprayed with powder, which not only has a high strength, but also has a good resistance to salt spray. The inner part of the iron network is covered with cotton, which can prevent the external rain water from entering directly, and play a waterproof role.

The VR118SUBa speaker system is designed to be maintained. To reduce interference and improve sound quality.

VR118SUBa speaker with VEYRON series full-range speakers are mainly used in meeting rooms, multi-function halls, small auditoriums, religious clubs, mobile performances and other venues. Especially for the performance of human voice: clear, full, but powerful ,which is the sound quality features of VR118SUBa and VERON series.



  • Single 18 inch low frequency inverted active low frequency speaker. 
  • Built-in high power amplifier module with DSP controller.
  • 2-way input and 2-way output socket ,with independent volume adjustment function .
  • The speaker adopts the built-in low frequency electronic frequency divider design to make the sound quality more natural, delicate and pleasant. 
  • The surface treatment of grill is made of powder spraying technology. In the case of nondestructive, it can be used for up to 5 years without rust. Waterproof filters are added inside the grill to prevent external rainwater from entering the woofer surface.
  • The paint and advanced painting technology used on the surface of cabinet makes the anti-damage capability of the surface three times higher than that ordinary process and paint.
  • VR118SUBa Acoustics Characteristics: clean, strong and flexible.
