Flatport Bassreflex 19mm X 180mm, 220mm depth

This is a flat bassreflex port with the equivalent to a 60mm diameter port. Suitable for subwoofer and housings in the area of 8" or 10" woofers and 35-45Hz of frequency. With a length of 220mm it is suitable for more compact housings as well.

The port is reinforced in the middle of the port for better overall strength

My suggestion for bassreflex ports is: after printing, sand it down on the edges with some sanding pads for most smooth airflow, maybe primer it and paint it black matte as a finish

Photos provided in the gallery show smoothed out edges for best sound results.
