The Rockville ELITE-5B is an incredible product. We developed this product to sound insanely good while offering more features than other brands. We also offer what we consider the best user experience.. . Sound. . The sound is incredible. We use high grade components like silk dome tweeters and a powerful 5.25" woofer and a beautiful and thick MDF enclosure with a rear port. We use a powerful class "D" amplifier along with digital sound tuning that gives this speaker system a warm sound with a full frequency range and punchy bass. The sound is just incredibly pleasing to listen too.. . Unique Features. . We offer many source playback options built into the unit including Bluetooth, USB, and memory card. Where this unit gets really cool is all of the input and output options. We have 2 mic inputs with echo control so you can karaoke along to your favorite songs. There is an optical input so you can easily plug these into your televisions optical output. There is an RCA output allowing you to either connect a powered subwoofer, another set of these speakers, or any other powered speaker or amplifier. There is also a standard RCA input to plug in other sources.. . Audio Controls. . We offer tons of audio control options. There is a master volume, bass, and treble knob so you can fine tune the sound to your liking. There are also preset EQ curves like Rock, Pop, etc so you can further customize the sound experience. What is really cool is that we offer a mic input with adjustments for mic bass, mic treble, mic echo, and mic volume. That also makes this the perfect system for karaoke, and conference rooms.. . Design. . We designed these to look beautiful with or without the grill. The grill is detachable and sits flush inside the unit. The unit has rounded edges and a smooth design that will look good in any living room, computer room, or bedroom. We also offer this speaker in multiple color options such as white and classic wood.
