Summary: These speakers have been on my watch list since they came out a few years ago. At $3,000 a pair they’ve been a bit out of my price range. When a recent sale from Polk presented itself, I snapped up a pair! Unboxing: Wow, these puppies are heavy. At 78 lbs these are about 20% heavier than the LSi15s at 66 lbs. All of the internal bracing and separate driver chambers makes for a heavy speaker.
