Advanced Design

Frequency response measurements clearly indicate the degree to which unwanted resonances and colorations have been brought under control. Thus, the ability to measure accurately is a fundamental part of building a better speaker.

At Paradigm, our concern with sonic accuracy led us to create research and development facilities that are among the most sophisticated and comprehensive in the world:

  • Two controlled double-blind listening room for repeatable, accurate subjective speaker analysis
  • 36,000-cu-ft (more than 1 million litres) high-resolution anechoic chamber
  • Highly advanced digital data-acquisition measurement system operated with software developed and written by Paradigm researchers (right)
  • PARC, the Paradigm Advanced Research Center, a facility dedicated to the design of state-of-the-art electronics, software and advanced technologies

We also take advantage of a number of highly advanced tools for component design. One of the most useful is a process called Finite Element Analysis, or FEA. FEA can be used to optimize drive units and enclosures, detect break-up distortion in cones and domes, monitor magnetic flow or heat dissipation, perform stress analysis, and more.

We use FEA to help design a magnet structure. First, a simulation of the structure is fed into the FEA program. After assigning detailed sets of material properties (simulating steel or ceramic, for example) to each of its components, the entire structure is broken down into a mesh of connected points, or elements. Our engineers can then enact "What if…" Scenarios, making "virtual" material substitutions or design changes and observing their effects on the magnet structure as a whole.

Using FEA and other such processes to optimize speakers, Paradigm engineers can develop prototype after prototype before actually building a single speaker. And since improving speakers is a continual experimental process, the ability to almost endlessly experiment helps us produce consistently better-sounding, more reliable speakers.
