Logitech z623 2.1 Speaker Review


The days when your computer speakers were a couple of extremely tinny, usually beige, definitely cheap and nasty offerings are long behind us. There was a period when surround seemed to be the dominant way the market was heading, but I think even the most dedicated gamer will understand that cabling a 7.1 setup in a manner that didn't look like an explosion in a spaghetti factory was too difficult. 

Lately the designs have all been aimed squarely at producing high fidelity 2.1 audio, rather than just adding more speakers. It's a lot easier to put a subwoofer at your feet and a couple of satellites on your desk and so it's a direction we are all in favour of here at OC3D.

One such speaker set arrived in our offices from the fine folks at Logitech. The z623 2.1 THX certified speakers. We can't see the letters THX without hearing Grandpa Simpson shouting "turn it up".

As with any set of speakers it's all about the looks and the audio, so let's get down to brass tacks. 

Technical Specifications

200W RMS?! That's a serious amount of volume for what is a set of speakers on your desktop only a couple of feet in front of your ears. We remember when satellite speakers used PMPO to pump up the quoted output to triple digits. The Logi's are doing it in RMS. With a frequency response of 35Hz-20kHz and full THX certification, the Logitech z623 promises to deliver bucketloads of loud and lovely audio.

Thanks for the review. Especially since i'm looking for a new 2.1 system.

If I may suggest something, it would be to also include a couple of 'in use photos'.

I'm somewhat space limited, so seeing the sub (and fronts) 'in use' around a PC and monitor would make it much easier to get a feel for the size.

My very old Yamaha 2.1 setup has not been replaced, because it has a super nice compact sub than stand on top of by PC cabinet and its speaker and all the dials is on the 'narrow' end of it. So it takes up little space in front, but goes a bit deeper. This is perfect for me.

While this is a 'special need' i think others may also like to get a feel for how the setup looks 'in use' and that is difficult from only closeups.Quote

I've owned these speakers for ~4 years. Pretty good, well worth the price IMO. The only issue I've had is with the right speaker cable - due to the type of connector, it sticks out quite far from the sub and can be subject to strain. Mine is slightly damaged and requires wiggling around a bit every now and then to get it working, and since that cable is integrated with the speaker, it's not easily replaced.

So if anyone's thinking of getting them, just be mindful of that Quote

Still own and use the z5500 THX in a 3.1 setup. Love the sound, these look really cool tho.Quote

Hey guys!

Ive owned these speakers for a few years now and I have a little secret... an Audio Engine D1 DAC. I run optical from the PC to the DAC and then gold plated RCAs to the Speaker unit and its amazing. Ive had neighbours complain for years and the bass penetrates the neighbours houses and gets me in heaps of trouble if i touch the bass dial (usually with a few drinks in my belly)
This unit is amazing and sometimes its on 20%-50% sale.

(DAC price was almost as much as the speakers btw)Quote
