About Lange: Research & Development

Fine tuning and critical decisions relative to the performance of our speakers are made with the help of MLSSA test system by Hans A. Lange. A team of trained FOH engineers feeds us with important information we use to keep our products responsive to the market needs. Internal CAD/CAM procedures allows the quick development of wave guides used in line arrays. FFT testing ensures that those complex devices work in accordance with the technical needs of the product.

Components such as low frequency drivers, mid frequency drivers and high frequency drivers are partially designed together with Faital S.p.a using the latest CAD and FEA modeling techniques. All electro-acoustic and mechanical performances are simulated and then carefully studied by a team of trained & skilled electro - acoustic engineers.

The use of NdFeB through almost the entire range of drivers allows an important weight reduction . In fact when comparing ferrite and NdFeB magnets with the same magnetic induction in the gap, the results shows that NdFeB transducers are 3 to 6 times lighter than ferrite.

Complex parts, such as wave guides and line array suspending systems are drawn by Hans A. Lange, produced in Switzerland by skilled mechanical engineers trough modern, high tech CNC machines. This enalbles to change or tailor specifical geometries immediately, without the need of new, costly mouldings.

Production of the wooden parts, such as cabinets & low frequency horns is accomplished by extensive use of computer controlled CNC routers. The exclusive use of finnish birch on all cabinets is a guarantee for long term stability and durability on the road.

Final testing consists of endless listening sessions beside to MLSSA testing equipment from DRA - Florida (USA). All types of music are used to tune each of our speakers in order to make sure that the customer receive not just a speaker, but an item that allows enjoying music. The better the recording, the better the result.
