Unlike your family singalongs, the Harman Kardon Nova Wireless Stereo Speaker System ($300) puts an emphasis on quality acoustics. This is a powered 2.0, stereo speaker system with performance-tuned 2.5” drivers and 1.25” tweeters that aim to deliver a richer listening experience. The passive radiator also promises extended bass response. The Nova adapts easily to nearly any audio system, and offers both analog and optical connections as well as Wireless Bluetooth with NFC, cranking out 40 watts of power. Now just tell Aunt Connie to take it down a notch.
