Mission SX-3 is a compact bookshelf speaker designed to deliver high-quality sound reproduction suitable for both music and home audio systems. Its design features a sleek finish and is typically constructed using a combination of MDF for resonance control and a stylish veneer for aesthetics. The speaker utilizes a 4-inch polypropylene woofer that provides tight bass response and a 1-inch aluminum dome tweeter for detailed high frequencies. It has a frequency response ranging from approximately 56 Hz to 20 kHz, ensuring a balanced sound across the audio spectrum. The nominal impedance is usually rated at 8 ohms, making it compatible with a wide range of amplifiers. With a sensitivity measured around 86 dB, the SX-3 is efficient enough for most listening environments. The speaker is designed with a rear bass reflex port to enhance low-frequency performance, which allows for a more extended bass response without compromising clarity. Its dimensions typically allow for easy placement on bookshelves or stands, with a design that integrates well into various home decor styles.
