What Klippel does

Klippel GmbH is a privately held German test-and-measurement company founded in 1997 in Dresden by Prof. Wolfgang Klippel, specializing in electroacoustic transducer and audio system diagnostics. Its portfolio centers on four product lines: the R&D System (modular development platform built around the KLIPPEL Analyzer KA3 hardware and dB-Lab software, with modules for linear and nonlinear parameter identification, holographic near-field scanning, 3D distortion, and multi-tone measurement), the QC System (end-of-line quality control with Standard, Pro, and Stand-alone editions), KLIPPEL Controlled Sound (KCS, an adaptive nonlinear control algorithm for loudspeaker protection and distortion compensation), and KLIPPEL Endurance Testing (KET, a multi-channel reliability and life-test solution). The technology is rooted in nonlinear lumped-parameter transducer modeling and IEC 60268-21/-22/-23 measurement standards, with patented holographic near-field scanning and KCS adaptive control as differentiators.

The company serves loudspeaker manufacturers, automotive audio suppliers, professional audio and public-address OEMs, hearing aid and headphone/earphone developers, and electronic musical instrument producers. Revenue is generated through one-time hardware and software module sales, KCS licensing (including embedded implementations such as the Nuvoton NAU83G60), calibration and support services, and a growing education and training business (online courses, KLIPPEL LIVE webinars, in-person workshops, and a 3-day TU Dresden lecture). Distribution is via a global reseller network, with exclusive partners Warkwyn North America (since 2015) and Warkwyn Japan (from May 2026). Following a 2022-2023 management succession, Benjamin Barth is sole General Manager while Wolfgang Klippel continues as research consultant, and a KLIPPEL Foundation has been established by the founding family.

Core offering

Klippel develops, manufactures, and sells modular measurement and control systems for electroacoustic transducers and complete audio systems. Its product lines include the R&D measurement system (KLIPPEL Analyzer KA3 hardware plus the dB-Lab software platform), the QC System for end-of-line testing, the KLIPPEL Controlled Sound (KCS) adaptive loudspeaker control technology, and the Klippel Endurance Testing (KET) multi-channel life-test solution. The company also provides calibration, support, consulting, and education services for loudspeaker developers and manufacturers worldwide.

Product overview

KLIPPEL GmbH offers a modular product architecture centered on measurement and control technology for electroacoustic transducers and audio systems. The core portfolio comprises four main product lines: the R&D System (modular development platform with KLIPPEL Analyzer hardware, dB-Lab software, and measurement modules including NFS, LSI, FLSI, LPM, SCN, TRF, DIS, TFA, MTON, TBM, and LAA); the QC System (end-of-line testing platform with multiple versions including Standard, Pro, and Stand-alone, featuring test modules like SPL, MSC, BAC, IMP, MTD, ALS, SAN, EQA, 3DL, and DOC); KLIPPEL Controlled Sound (KCS) - adaptive nonlinear control technology; and Klippel Endurance Testing (KET) - multi-channel power and life test solution. All systems are powered by the unified dB-Lab software platform (version 212) which supports both R&D and QC operations. Supporting services include online training, KLIPPEL LIVE webinars, face-to-face workshops, and professional measurement consulting.

Products and services

• R&D System Modular measurement system dedicated to the development of transducers and complete electro-acoustical systems, combining the KLIPPEL Analyzer hardware, the dB-Lab software platform, and specialized measurement modules for linear parameters, large-signal behavior, 3D sound radiation, and distortion analysis. It is sold to audio R&D teams working on loudspeaker and transducer design.
• QC System Quality control system dedicated to end-of-line testing and maintenance of audio products, available in multiple software versions (Standard, Pro, Stand-alone) and combining analyzer hardware with modular test capabilities for defect detection (rub&buzz), max SPL verification, and standardized PASS/FAIL testing of loudspeakers and audio devices.
• KLIPPEL Controlled Sound (KCS) Adaptive nonlinear control technology for loudspeakers that continuously identifies time-variant speaker parameters to provide overload and thermal protection while compensating linear and nonlinear distortion through digital pre-processing of audio signals, sold as licensed technology for integration into audio products, AEC, ANC, and beam-steering applications.
• Klippel Endurance Testing (KET) Multi-channel, long-term power and accelerated life test solution for quality assurance applications including validation checks and type approvals, capable of testing up to 32 devices simultaneously using one PC and virtual soundcard, with Dante network streaming support for flexible test signals and detailed failure process monitoring.
• dB-Lab Software Unified software platform (version 212) that powers both the Klippel R&D and QC systems, providing measurement control, data acquisition, analysis, templates, and module management for all Klippel measurement products.
• KLIPPEL Analyzer (KA3) Primary measurement hardware unit used for both R&D and QC applications, providing signal generation, acquisition, and analysis capabilities for transducer testing and audio system measurements.
• Near Field Scanner (NFS) Patented holographic near-field scanning module that measures the complete 3D sound field radiation of loudspeakers using wave expansion to simulate free-field conditions in normal rooms, providing high-SNR directivity measurements without anechoic chambers.
• Multi-Scanning Workbench All-in-one measurement system that combines holographic sound field scanning, mechanical vibration analysis via laser vibrometer, and electrical measurement, enabling comprehensive multi-domain transducer analysis in a single instrument for verification of FEM/BEM simulations and transducer design optimization.
• KLIPPEL Online Training Self-paced e-learning courses on loudspeaker measurement fundamentals and Klippel products, including theory, demo movies, software tools, and multiple-choice assessments leading to a Certificate of Knowledge for course participants.
• Face-to-Face Training and Workshops In-person workshops and seminars covering loudspeaker design optimization, measurement techniques, and production testing, including 2-day in-person user training in Dresden and the 3-day 'Sound Quality of Audio Systems' lecture at TU Dresden.
• Measurement Service and Consulting Professional measurement and consulting service using Klippel equipment to characterize loudspeaker drivers, systems, and components for customers that need expert analysis without owning the full test setup.

Others

• Harman International: Harman is both a potential customer of Klippel instruments (as a major automotive audio and loudspeaker OEM) and historically a developer of nonlinear loudspeaker control IP (Wolfgang Klippel's prior employer), making it an adjacent ecosystem participant rather than a direct seller of competing measurement systems.

Broad incumbents

• National Instruments (NI): NI's modular data acquisition and PXI-based test platforms are used in audio and transducer test setups at larger manufacturers, serving as a broad incumbent alternative to Klippel for companies preferring customizable test architectures.
• Rohde & Schwarz: Rohde & Schwarz is a broad test & measurement incumbent whose audio analyzers and oscilloscopes can be configured for audio/loudspeaker testing, offering Klippel meaningful indirect competition at large enterprise and R&D customers.
