Introducing the brand new 3.UMA. This special and exclusive component driver is a concept born way back in the ’70s, it aims to concentrate medium and tweeter emissions on a single virtual point. This minimizes phase delays and irregularities at the crossover point. The speaker is composed of the 1.1 "/ 28 mm tweeter and the 3.65 midranges, with different dust cover to have a midrange function (not wide range) and not interfere with the tweeter frequencies.

The 3000 series includes two convertible speakers, with a 6.5”/165 mm or a 6x9”/150x230 mm woofer, and a 1”/25 mm dome tweeter. 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 center 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.

They are supplied with accessories for flexible installation, however, grilles are not included.
