We like the quirky design. The speakers look like they could fire missiles and the subwoofer is a tall imposing cylinder. The speaker cables provide strong contrast in bright red. See all audio reviews.
The pair of stereo speakers sit on metal stands which allow them to tilt up or down depending on your positioning. If you like you can even mount them to a wall. The cables are 2m long, giving a good amount of freedom. Take a look at Group test: what's the best speaker set?
With a total of 40W, this speaker system has plenty of volume available – whether you're watching a TV show, film, playing games or listening to music. It's split up by 10W for each satellite speaker and 20W for the subwoofer.
The sound is impressive considering the price. It's best described as smooth and easy on the ears with a nice distribution across its frequency range. Each satellite speaker has two 50mm drivers rather than a larger woofer and smaller tweeter. This means the Z553 tops out at 17KHz but means no cross-over issues between mid- and high-range drivers. Treble, therefore is a bit lacking and our main criticism of the Z553's sound quality.
We really like the volume dial which Logitech calls the 'control pod' which is wired to the subwoofer with a VGA-style cable. It has a smooth action and doesn't adjust the volume too sensitively. In addition, it has dial for bass on the rear, and a headphone jack for times when you don't want to disturb others.
We like the fact the subwoofer volume can be adjusted via a dial on the back of the control pod, to suit your taste and the sound source. The 4in down-facing driver delivers a well-rounded sound but the tall tube design means certain notes are amplified, which can sound strange.
A lot of laptop speakers have only a 3.5mm jack input but the Z553 speakers also has stereo phono inputs on the bass speaker, and a second jack input on the control pod. This means you can have multiple device plugged in. There's no Bluetooth but Logitech sells an accessory which can add this for £35.
