    Notes on the Lineup

    • SwiftLock® tool-less mounting is available on all "6" and "8" (Enhanced/Premium) tier models, but not on the entry-level IC-605/IC-610/IC-610T.
    • "T" suffix models (IC-610T, IC-620T, IC-820T) are Single Point Stereo speakers — a single unit that delivers stereo sound from dual tweeters/voice coils, useful where only one ceiling location is practical.
    • "IW" models are in-wall versions of the 6.5" Enhanced/Premium Performance speakers, sharing driver specs with their in-ceiling IC-620/IC-630 counterparts but in a rectangular in-wall form factor.
    • All models use 8-ohm nominal impedance and share the same 8.375" round cut-out for the 6.5" ceiling line and 9.875" round cut-out for the 8" ceiling line, simplifying retrofits/upgrades within the same series.
