Voice Coil and Magnet

The voice coil is the driving force behind the woofer. The HP1950 often features a high-temperature voice coil, usually around 2 or 3 inches in diameter. This allows it to handle more power and dissipate heat more efficiently, reducing the risk of burnout. The magnet is another critical component. Typically made from ferrite or neodymium, the magnet provides the magnetic field necessary to move the voice coil and, consequently, the cone. A larger and stronger magnet generally results in better efficiency and control over the cone's movement.

Impedance

The impedance of the HP1950 is usually available in configurations of 4 ohms or 8 ohms. This is the electrical resistance the woofer presents to the amplifier. Matching the impedance of your woofer to your amplifier is crucial for optimal performance and to avoid damaging either component. Most amplifiers are designed to work with specific impedance loads, so check your amplifier's specifications before connecting the woofer.

Sensitivity

Sensitivity is a measure of how efficiently the woofer converts power into sound. It's usually measured in decibels (dB) at 1 watt at 1 meter. The HP1950 typically has a sensitivity rating in the range of 88 dB to 92 dB. A higher sensitivity rating means the woofer will produce more sound with less power, making it a good choice for systems where amplifier power is limited.
