With the Q Acoustics 3020i, you can fill a medium-sized living room with sound. These bookshelf speakers have a frequency range up to 30,000Hz. This allows you to enjoy a more detailed reproduction of the high frequencies. You won't hear any vibrations of the design, since it's specifically designed not to produce any extra sounds. This means your listening experience remains intact. When the sound is reflected into the room via the back wall, you can put the included foam plugs in the bass reflex ports. This way, you prevent the sound waves from moving back towards the listener and make sure the sound reproduction remains balanced. This means you'll listen to music exactly the way the artist wants you to.
Note: when you want to use these speakers, you need an amplifier.
