With the Jamo S 803, your favorite movies or music will sound extra rich and clear. This bookshelf speaker has a 25mm tweeter and a 127mm woofer. Thanks to the WaveGuide technology you'll get natural sound reproduction. The bass reflex port is on the front, so you can place the speaker against the wall without problems. The bass does not distort. The heavy MDF design is very sturdy, so you won't be bothered by unwanted vibrations. If you want to expand the set with S 8 ATM Dolby Atmos speakers, you can just place them on top of the speaker's connection points.
