Fs, Vas and Qts can all be modified and the coil former can be made of either aluminum or Kapton or a combination of both. In special cases the cone material and suspensions parts can also be changed.

Gap height and coil length as well as diameter can be selected individually and the magnet size can be altered to fit the needed strength required. Please see the price lists to experience which driver-magnet-coil size combinations are possible.

For the less experienced customer, we have made a line of multipurpose drivers, presented on this site, from 4” mid-woofers through 15” subwoofers, enabling you to approach a project, the more conventional way. It is also possible to use one of the standard drivers as a raw model, and getting parameters changed in the direction you wish.

Please note – we can only operate within the laws of nature.

Features of the Flexunits drivers:

  • The cone material is stiff well damped Polypropylene, that result in controlled roll off without breakups. The cones exhibit great uniformity.
  • Complete freedom from dynamic compression is achieved by generous ventilation through the polepiece, under the spider and from the voice coil gap. This is important insure free movement, low distortion and high power-handling.
  • Iron parts are machine turned to obtain the highest possible contact and amount of magnetic energy transfer.
  • Chassis made of diecast, bolted together aluminum parts.
  • The magnets are of low loss ferrite type. The magnetic force is individually adjusted on every driver.
  • A uniform resonance frequency is assured by minimum suspension tolerances.
  • The voice coils are wound of copper clad aluminum wire in a hexagonal pattern to create a very compressed structure.
  • Gold plated input connectors.
  • Long life - All our drivers can be repaired in case of accidental abuse.
