The AL 170's lightweight aluminum cone ensures a fast pulse response, making it suitable for high-fidelity audio applications. Its design allows for integration into various cabinet sizes, with recommended volumes ranging from 10 liters to 30 liters in both closed and bass reflex configurations, achieving tuning frequencies between 39 Hz and 79 Hz. This versatility makes the AL 170 an excellent choice for audiophiles and speaker builders aiming for superior low-midrange performance in their custom speaker designs.
