At Adire Audio we design all our transducers to produce very deep bass at realistic levels in a remarkably compact cabinet with extremely low distortion, minimum compression and fast transient response.
We extensively design, test, weak and retest until we are 100% confident in the product we are releasing. All Thiele-Small parameters are pulled after a 12 hour break in period, giving you accurate parameters for what your transducer will perform like after break in is complete.
