Bass and lower midrange reproduction is handled by an 8” aluminium cone woofer, optimized for stiffness and control in the frequencies where cone breakup is far removed from the operating range.
While aluminium cones can be problematic in the upper midrange, in the lower registers they become a major advantage—delivering a level of clarity and articulation in bass dynamics and lower male vocals that is both powerful and remarkably detailed, given the right cone geometry.
The woofer motor is engineered for deep bass extension, high excursion capability and low distortion, supported by a robust surround structure with internal ribbing. This geometry is simulated using COMSOL to ensure stable cone behavior even under extreme excursion, keeping distortion tightly controlled at high output.
The low distortion levels are achieved by using multiple aluminium shorting rings in the motor, that reduces and evens out the inductance over the entire moving range of the woofer.
Low-tuned ports without the downsides.
With the exception of the 1610 Slim (sealed design), 1610 speakers use large, low-tuned ports for strong bass extension while avoiding turbulence.
To avoid turbulence under high excursion, and especially considering the ports are tuned to dig out the deepest bass-tunes, we have opted for large ports.
Because very long ports can introduce resonance, the port system is engineered to also reduce port resonances by introducing strategically placed holes covered in damping material, creating a controlled, cancelling airflow behavior that helps phase out resonance effects while keeping turbulence in check.
