A loudspeaker test to suit your budget

The widely-used NTi Audio RT-Speaker loudspeaker test system is now available in three editions, graded on functionality and price. This allows you to select the appropriate solution that fulfills your individual loudspeaker testing requirements.

The combination of RT-Speaker software, PureSound™ Rub&Buzz detection and the FX100 or RT-2M audio analyzer has been the de-facto standard for end-of-line testing in loudspeaker manufacturing for over 10 years. While the software is used mainly in high-volume loudspeaker manufacturing, the new editions make RT-Speaker attractive also for smaller companies.

Basic Edition
For companies that want to replace their subjective ”Golden Ear” test with a cost-effective, objective test system that creates consistent results. This edition contains the Rub&Buzz test that uses NTi Audio’s PureSound™ technology.

Standard Edition
Designed for companies who test smaller quantities of loudspeakers, such as R&D, sample QC testing or PA rental companies. While the Standard Edition offers a comprehensive complete set of measurement functions, the test system can only be operated in manual mode.

Premiere Edition
Contains the full RT-Speaker functionality and is therefore the optimal solution for testing mass production of loudspeakers. Besides the complete set of measurement functions, the Premiere Edition offers numerous helpful features for system integration such as digital IO, TCP/IP interfaces and barcode scanners. Various user access rights, a comprehensive statistic tool as well as the ability to classify results complete the list of features.
