The perfect combination of technologies and materials in the design of the Sound Line Pro acoustic systems

Unique technology of cast aluminum diffusers of the 165 mm mid-bass driver SL PRO-MW165 and 76 mm mid-range cone emitter SL PRO-MD80

The technology is a Fibonacci spiral (aka the Golden Spiral – the basis of the Golden Section), where each new turn has a radius equal to the sum of the radii of the two previous turns. In relation to the diffusers of acoustic systems, biomimetic design is increased damping and rigidity of the diffuser, providing enviable linearity, wide frequency response and stable peak performance of the speaker system.

The speaker baskets are cast from an aluminum alloy with ultra-low resonance and good ventilation of the voice coil.

Neodymium magnetic systems. Decent power factor plus low mass of the moving system, and as a result, quite high sensitivity. And this means that the speakers have an excellent impulse response. The sound is not "smeared" on fast compositions.

The diffuser suspensions are made of heat-stable butyl rubber, and the centering washer with a progressive profile maintains linearity of movement in any temperature conditions.

The SL PRO-TW25 tweeter with a 25 mm artificial silk dome has an upper cutoff frequency of 25,000 Hz. The body, which is also the load chamber, is made of anodized aluminum. The tweeter grill is removable, which allows you to install the emitter in a regular place in the car.

The SL PRO-CS 2.0 crossover has an original design and small dimensions. The switching terminals are convenient and reliable. Depending on the location of the speakers in the installation, the crossover has a switching of the HF band level -3/0/+3 dB.
