Rainbow SL PRO-C260 component speakers (165 mm).

Rainbow SL PRO-C260 component speakers (165 mm).

The line is created for sophisticated connoisseurs of high-quality sound of car systems.
The ideal combination of technical solutions and materials in the design of the Sound Line Pro acoustic system line
Unique technology of cast aluminum diffusers of the 165 mm mid-bass speaker SL PRO-MW165 and 76 mm mid-range cone emitter SL PRO-MD80
It 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 - increased damping and rigidity of the diffuser, providing enviable linearity, wide frequency response and stable peak performance of the speakers.
Speaker baskets are cast, made of 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.
Diffuser suspensions made of heat-stable butyl rubber, a centering washer with a progressive profile maintain linearity of travel 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.
