New range of subs

Our range of subs has expanded and we now offer a range of subs for music, home theatre and combined systems. L series is our entry level product line and F/E series is our premium product line.

Output comparison

Every one of our subwoofers has bass extension lower than 20hz. Our frequency response specification is based on -3db point which is far more stringent than +/-3db that other manufacturers have used. +/-3db is more like our -6db specification because the former is equivalent to 0db/-6db specification. Lower bass extension is also advantageous in multiple sub setup.

At 20 Hz, our subs vary in their maximum output capability. The output at 20 Hz is shown relative to F12.

  • F12: 0db (baseline)
  • F8/FM8: -1.5db
  • L12: -1db
  • F12-300: -0.5db
  • LV12F: +2.5db
  • L22: + 4db
  • LVX12: +4db
  • FVX12: +4.5db
  • E15HP: + 5db
  • F15HP: +5.5db
  • G22: 6db
  • E22: 6db
  • F18: +7.5db
  • FVX15: +8db
  • FV15HP: +11db
  • G25HP: +12db
  • FV18: +14db
  • FV25HP: +17db

Home theatre subs

For systems where home theatre is the main priority, we recommend our vented subs. At 20 Hz, a vented sub is comparable to the output of two similar sealed subs. LV12F is our lowest cost sub and is designed for smaller rooms and modest budgets. Our larger 15" subs are suited to larger rooms and have substantially more output. Don't be fooled by typical comments about vented subs lacking accuracy. These subs are tight and musical.

Music only systems

For music-only systems we recommend our sealed subs. We have sealed subs in various sizes and finishes. Where high output at 20 Hz is not needed, our sealed subs will match the output of their vented equivalents. In addition, greater extension is possible. Combined with room gain, in-room extension to 14 Hz or even lower is possible.

Combined systems

For combined music and home theatre systems, many of our 15" sealed subs are a good all round compromise. Our dual sealed 15" F25 is a very good choice, offering the LFE output of our vented subs but with the added bonus of greater midbass efficiency and output.

Direct Servo technology

The secret to accurate bass is in our patented Direct Servo technology.

A sensing coil provides immediate feedback to ensure the cone precisely follows the input signal. The result is very tight, accurate and dynamic bass. Unlike many other non-servo subs which exhibit two-mode bass: either with too much bass when volume is up or with too little or no bass when the volume is down, our higher resolution subwoofers allow customers to listen at lower level and yet able to hear detailed bass in a wide range of volume level.

How to purchase

Our range of Direct Servo subwoofers on this page are available for purchase on-line direct via our website. They are also available through Ascend Ascoustics sold with their speakers.
