Proficient Signature In-Wall LCR Speaker IW675S with Dual 6.5" Kevlar Woofers and Pivoting 1" Aluminum Tweeter (Replaces IW655)
Big sound, built into the wall.
The IW675S is an in-wall LCR speaker with dual 6-1/2" Kevlar woofers and a pivoting 1" aluminum tweeter, made for home theater and whole-home audio.

Two woofers, a pivoting tweeter and tone switches give you control over how it sounds in your room.
Dual Kevlar woofers
Two 6-1/2" Kevlar woofers handle the low end.

Rated for 150W with 8Ohm impedance and 90dB 1W/1m sensitivity.
Pivoting aluminum tweeter
