  1. Why aren’t the front edges of your cabinet rounded?

Rounded edges result in flatter on-axis frequency response measurements in the higher frequency bands. The on-axis measurement alone does not define how the speaker will sound. Off axis curves also need to be considered. Rounded edges reduce diffraction but those peaks and dips occur at different frequencies as the microphone is moved off-axis. When we average the on and off axis measurements, such as in the case of a listening window measurement, peaks and dips tend to average to a smooth frequency response.

We also didn’t radius the edges because many of you will apply veneer to our kits and it’s much easier to apply veneer to a flat surface.

  1. Why do all your designs use rear-firing ports? What if I want to hang the speaker on my wall?

Front firing ports can cause frequency response deviations and be the source of noise at lower frequencies when driving the speaker at high levels. A port tube is a pipe and just like a pipe organ, it has a resonant frequency. The woofer excites this resonance and it interferes with the woofer’s direct forward sound. The interference is drastically reduced if the port is located on the back of the cabinet.

For the most accurate sound, box speakers shouldn’t be mounted to a wall. If you must, many stands locate the cabinet a few inches away from the wall which is more than enough to not limit the port output.
