2-Way (Bass & Treble Combined): It includes two speakers. The woofer for low frequencies and the tweeter for high frequencies.
3-Way (Full Range): They include the woofer for low frequencies, a speaker suitable for reproducing mid frequencies, and the tweeter for high frequencies.
The resistance (Ohm) shows how “easily” the current passes through the speaker. It must match your source (radio or amplifier) so that the sound comes out clear and without the risk of overheating.
4 Ohm (Direct connection to the radio): The standard choice for 90% of cars. It connects directly to the factory screen or the car radio with no risk at all.
Coaxial (With built-in tweeter): The tweeter (for high frequencies) is positioned at the center of the woofer (for low frequencies), ensuring that all frequencies are emitted from the same point for a more uniform and compact sound.
