One look at the Polk Signature Reference Components and you will know this is a quality product and yes, the beauty goes further than skin deep. You’ll notice a trend of rather large crossovers (Those boxes with the speakers) in all of my top five picks and that is due to the fact that to properly direct and control sound to speakers you need to use quality components. To handle the amount of power that you will want to use to make these speakers sound right companies like Polk use larger electrical parts to minimize power loss and maximize output.
Polk uses exotic materials in their mid-woofers and tweeters just like every other company in my top five and their approach uses aerated polypropylene cones with nitrile butyl rubber surrounds to give the proper amount of rigidity yet with full flexibility. The result is a smooth sound that works well for all types of music from classical to rap.
For the crisp sparkle you expect from tweeters Polk uses 22mm ring radiator tweeters that are usually found in home speakers. Because they use quality components and designs in their crossovers, Polk gets a smooth sound from these tweeters but don’t lose the impact needed to work in the mobile environment.
