Sala Acoustics Aurora MTM
Designed by Sala Projects

Aurora MTM is a 2-way Home Theater center speaker specifically designed for PETG 3D printing.
The structure uses an MTM configuration (Midwoofer-Tweeter-Midwoofer) to improve vocal clarity, horizontal dispersion, and cinematic sound performance.

The project was designed both as a ready-to-use speaker and as a modular platform for future upgrades, including different drivers, crossover systems, and internal acoustic treatments.

Main features:

Fully 3D printable cabinet
Modular removable structure
Separated internal chambers
Integrated TPU gasket for proper air sealing
Support for M3 and M4 threaded inserts
Compatible with Home Theater systems
2-way MTM configuration
Series woofer wiring for final 8 Ohm impedance
Passive crossover support
PETG optimized design
Recommended materials:

PETG for all structural parts
Soft TPU 1.75 mm filament for the gasket
Acoustic foam for internal damping
Recommended print settings:

Layer height: 0.2 mm
Walls: 6+
Top/Bottom layers: 8–10
Infill: Gyroid 20–25%
Supports required
The project uses threaded inserts:

M4 inserts for the main front baffle mounting
M3 inserts for woofers, tweeter, and rear terminal cup
Ideal for:

Home Theater systems
DIY audio projects
surround systems
custom upgrades
acoustic experimentation
This project includes:

Modular STL files
Removable structure
Crossover support
Air sealing system
Internal wiring support
Designed and developed by Sala Projects.
