” The third of three Pioneer S-IW in-wall speakers, the Pioneer S-IW831L is a direct upgrade from the Pioneer S-IW631L in that it features a larger 8” (versus 6-1/2”) Polypropylene woofer. In all other ways, however, the S-IW831-LR is exactly the same as its predecessor. For instance, the S-IW831-LR also boasts a 1” pivoting soft dome tweeter, not to mention a humidity-resistant dual voice coil design that provides single-point stereo performance in all sorts of environments. In addition, the S-IW831-LR sports a dependable 8-Ohm impedance rating for higher-quality amplification with single and multi zone applications, internal Thermal Resetting Protection Circuitry that offers greater reliability and reduces the need for frequent visits to replace damaged speakers, a 100w power handling, and 3-position treble contour controls to customize high frequency outputs to an individual’s specific tastes. It should also be noted that the S-IW831L is designed to fit within standard 16” stud spacing. The Pioneer S-IW831L retails as a pair (two speakers) for a more expensive $475.00 (versus $375.00) and comes with a 1 year limited warranty.
