Convertible Speakers

By removing the tweeter from the woofer, it allows the system to transform from a coaxial system to a separate 2-way system.​

When using the woofer in "component" mode, the tweeter support is replaced by mounting an ABS phase plug on the pole piece.  This detail is essential to focus the high frequency information in the centre of the cone.  The ABS phase plug innovative design ensures that the speaker response remains linear at mid-high and high frequencies.

Its concavities arranged on a very open angle help to increase linearity even at accentuated listening angles.

This is very important for the reproduction of the medium and medium-high range when the woofer is installed in the lower part of the door.
