RMS is a more realistic measure of the continuous power the subwoofer can handle, whereas peak power is the maximum short-term power it can handle. Matching the RMS power with your amplifier's output is essential. Second, check the impedance, typically expressed in ohms (Ω). The dual voice coils offer flexibility. You can wire the coils to achieve different impedances (e.g., 2 ohms, 4 ohms, or 8 ohms), which you then match with your amplifier's capabilities. Next, the frequency response, which tells you the range of frequencies the subwoofer can reproduce accurately. A wider frequency response (e.g., 30Hz - 500Hz) indicates the subwoofer can handle both deep bass and higher frequencies, offering a more comprehensive sound. Sensitivity is another vital specification, usually measured in dB (decibels). It indicates the subwoofer’s efficiency in converting power into sound. A higher sensitivity means the subwoofer will play louder with the same amount of power. Cone material is essential, as this affects the sound. Materials such as polypropylene and paper cones are common. They directly impact the sound quality, durability, and response. The voice coil diameter and magnet size also influence the power handling and performance of the subwoofer. The larger the voice coil and magnet, generally, the more power it can handle. Mounting depth and overall dimensions are very important, especially when it comes to installation. Knowing these dimensions helps to determine if the subwoofer will fit in your enclosure or car.
