The Revel Gem is a two-way dynamic loudspeaker with two 5-inch bass/midrange drivers and a pair of tweeters, one forward-firing, mounted between the woofers, and one rear-firing. The Gem is capable of solid response down to 40Hz and is impressively coherent. All Revel Ultima speakers can get loud without distorting the character of the sound, making the Gem exceptionally well-suited for home-theater applications.
