Pioneer SP-C21

The SP-C21 is a three-way center channel speaker from Pioneer that is a part of the company's Home Theater Speakers product line. Developed in conjunction with acclaimed audiologist Andrew Jones, this model is fitted with two 5 1/4-inch subwoofers and a single 1-inch soft dome tweeter with flush-mounted speakers grills for aesthetics and protection.

A six-component crossover is implemented for maximum-quality audio output, whether the unit is being used for standalone or home theater audio applications. The cabinet of the SP-C21 also features a curved shaping design in effort to decrease the likelihood of standing wave interference, resulting in the clear production of low, middle and high frequency signals.
