The IW-620 is the perfect in-wall choice for using in all of the primary listening areas of the home. From the kitchen to the living room to the master bedroom, the IW-620 is a speaker that you'll spend hours and hours listening to. The injection-molded polypropylene cone gives detailed bass response and the 1" pivoting silk tweeter can be aimed at your favorite listening spot. The integrated one-piece baffle / woofer basket adds enhanced rigidity and complements the deep bass sound. The IW-620 is acoustically matched to the in-ceiling speakers the IC-620 and the IC-820 so you can mix and match with these two speaker sizes as needed. The IW-620 uses the patented SwiftLock® by Swarm tool-less installation system which lets the speaker be installed quickly and easily with the simple press of a button at each of the four mounting dogs.
