 Here is a brief description of the services and facilities available at SSS and a discussion of our design philosophy.

SERVICES OFFERED         SEE  , EQUIPMENT PHOTOS     >>>     Loudspeaker System & Driver Measurements

We provide general engineering design, prototyping, and test and evaluation services in audio and acoustics with special emphasis on loudspeaker systems design. Services provided include: Loudspeaker system design, test and evaluation


Below is a partial list of facilities and equipment we have to support our services: In-house Free Air test facility



This section describes one aspect of our design services: our approach to the design of loudspeaker systems. All designs we do are based on actual measured data, not models or manufacturerís curves. This is the only way to properly account for the effect on acoustic performance of cabinet size, baffle/driver geometry and bass driver loading. The complete design process consists of the following steps.

  1. Driver selection
  2. Enclosure design for best low-frequency response based on selected woofer free-air parameters
  3. Construction of a prototype enclosure
  4. Installation and testing of individual drivers for frequency response, acoustic phase centre and impedance in the prototype enclosure
  5. Performance of computer aided and computer optimised crossover network design using test data from step 4
  6. Construction of a prototype crossover followed by complete prototype system assembly and testing
  7. Listening evaluation and final voicing of the prototype system. This step is based upon our own listening experience and customer feedback.
  8. Preparation of a full report detailing the design process, all test data and a full set of system design specifications and drawings
  9. The prototype enclosure can be made with unfinished MDF. Building it is usually the customerís responsibility. This is more cost effective than paying us to build enclosures. While we are responsible for the acoustic aspects of enclosure design, these considerations will be integrated with our customerís aesthetic goals.

Based on our extensive software library of previous designs and our experience with a wide range of drivers from many manufacturers it is often possible to eliminate steps 6 and 7 for systems with less critical performance requirements. For the simplest of requirements a "computer only" design involving just steps 1 and 5 may be sufficient.

For each design the customer receives a written description of the system including all pertinent specifications, response curves an enclosure drawing and a crossover network circuit diagram and parts list.

By working cooperatively with our customers and limiting our efforts to what we do best, we can greatly reduce your costs and speed up the design process.
