Non-Linear High Power Loudspeaker Box Design Software (including Inverse FINEBox)
Highly Accurate, Fast and Easy to Use
Advanced Automotive Loudspeaker Box Design Capabilities
LOUDSOFT’s Loudspeaker Box Design Software includes a specialized “Car” option that enables accurate cabin gain calculations for various enclosure types, including closed boxes and both inside and outside bass reflex ports.
Even sealed enclosures—when modeled accurately—can deliver well-extended low-frequency performance inside the vehicle cabin due to the natural gain effect of the space.
In the Bass Reflex Outside configuration, the port is connected to the exterior of the vehicle. This setup takes advantage of cabin gain to allow for a more compact enclosure while still maintaining powerful low-end response—ideal for space-constrained automotive installations.
Thermal and Power Handling Simulation
FINEBox PRO also simulates Power Compression, displaying the thermal behavior of the system during operation. It calculates Voice Coil and Magnet Temperatures, giving engineers valuable insight into the thermal limits and performance stability of their loudspeaker designs under real-world conditions.
System Integration with In-Car Measurements
Once the speaker system is installed in the vehicle, engineers can measure the acoustic response at multiple listening positions. These measurements can then be imported into FINE DSP, which enables simultaneous display and real-time equalization of several responses. This integrated workflow ensures optimized system tuning tailored to actual cabin acoustics.
Comprehensive Non-Linear High-Power Loudspeaker Box Design Software
LOUDSOFT’s Loudspeaker Box Design Software supports complex, non-linear high-power simulations for a wide range of enclosure types, including automotive applications. The software now features Inverse FINEBox, a powerful tool for determining optimal driver Thiele/Small (TS) parameters within a specific box volume or target low-frequency cutoff (F3).
Advanced Thermal and Compression Modeling
FINEBox performs direct simulations of Voice Coil Temperature and Thermal Compression under high power. It supports various enclosure designs, including Closed Box, Reflex, ABR, Band-pass, and Inter-Port alignments, enabling accurate multi-driver and multi-port simulations
All non-linear TS parameters and thermal data can be imported seamlessly from FINEMotor. For added convenience, FINEBox can estimate voice coil temperatures and thermal compression effects using TS parameters and physical driver dimensions—even without FINEMotor (fm3) files.
Trusted by Industry Leaders Worldwide
Leading companies across multiple sectors rely on LOUDSOFT’s Loudspeaker Box Design Software to enhance their loudspeaker projects. These include Ford Motor Company, BOSE, and renowned audio specialists such as Kicker, Rockford, PSB Speakers, QSC Audio and Sonavox.
FINEBox is used globally to refine a diverse range of audio products, from Hi-Fi and PA systems to car speakers, headphones, and micro loudspeakers—helping engineers design enclosures that deliver optimal sound and reliable performance under demanding conditions.

Frequently Asked Questions about our Loudspeaker Box Design Software
What types of loudspeaker enclosures can I design with LOUDSOFT’s Box Design Software?
LOUDSOFT’s software supports a wide range of enclosure types, including Closed Box, Bass Reflex, ABR (Auxiliary Bass Radiator), Band-pass, and Inter-Port aligned designs. It also accommodates multi-driver and multi-port configurations.
Can the software simulate thermal effects like voice coil temperature and power compression?
Yes, the software includes advanced thermal modeling features that simulate voice coil temperature and power compression at high power levels. This allows designers to predict performance and reliability under real-world operating conditions.
What is Inverse FINEBox and how does it help in loudspeaker box design?
Inverse FINEBox is a unique tool that calculates the ideal driver Thiele/Small (TS) parameters for a given box volume or target low-frequency cutoff (F3). This helps designers select or tune drivers that will perform best within a specific enclosure.
Do I need to use FINEMotor files to benefit from thermal and compression simulations?
No, while thermal data from FINEMotor files can be imported for detailed analysis, FINEBox can also estimate voice coil temperature and compression using only standard TS parameters and driver dimensions.
Is this software suitable for automotive loudspeaker design?
Absolutely. The software includes specialized features such as cabin gain calculations and supports designs optimized specifically for automotive environments.
Which companies trust LOUDSOFT’s Loudspeaker Box Design Software?
Industry leaders including Ford Motor Company, BOSE, Kicker, Rockford Fosgate, PSB Speakers, QSC Audio, and Sonavox use LOUDSOFT’s software to develop high-performance loudspeaker systems worldwide.
Can the software handle designs with multiple drivers and ports?
Yes, it supports complex configurations involving multiple drivers and ports or auxiliary bass radiators, allowing for highly customized loudspeaker designs.
