This project showcases my development in the Technology & Realization domain through: + Selection of components + Creating large and acoustically precise hardwood cabinets (woodworking skills) + Developing a hybrid crossover system with a combination of passive and active components (for the different frequency cutoffs). + Tweaking the setup using a Digital Signal Processor to ensure time alignment of drivers, correction of the impulse response and phase response of the speakers.
35Hz to 25kHz (+/-6db) frequency range, constant directivity sound pattern 35Hz to 25kHz, high efficiency—95dB 1W/1m on average, high power handling and output—100W and 115dB full range, <1% Distortion, beautiful sapele hardwood
