Logitech z623 2.1 Speaker Review

Conclusion

Like the worlds largest elephant the Logitech z623 2.1 THX Speakers are very impressive with a giant 'but'.

Build quality is important for any set of speakers, particularly 2.1 ones for your desk. After all, the subwoofer gets kicked whether you mean to or not, and the satellites are in the firing line for furious controller launches and knocking over of your beverage of choice. Fortunately the z623 are extremely robust. The case for the subwoofer is sturdy enough that you could kill someone with it and the satellites, despite their plastic casing, feel fantastic and have no flex in them at all. This isn't your aunties cheap plastic. The grills aren't for show either. We've come across many speaker grills which were there for aesthetic reasons and had all the protective qualities of a slice of bread in a thunderstorm. There are no such issues with the Logitech z623. 

Whenever we test audio we always do it with the flattest EQ profile and the barest minimum of adjustments. It's important to get a feel for the product in the manner that the manufacturers intended. Some models have monstrous bass as their natural setting, and some need a good kick to really get your chest pumping. The z623 are wonderfully neutral. Whether we were breaking our necks with Busta Rhymes, digging out our old white label hard house, grooving some classic rock or mellowing in the summer sun with some Pink Floyd, the z623 performed very well. The bass-heavy parts had plenty of boom to them without getting woolly or dominating your aural soundscape whilst the soft and gentle moments were reproduced with richness and subtlety. If you don't touch that dial, you'll be very pleased with the result.

At this point the elephant enters proceedings. Touching that dial. The volume control is nice and linear but despite an acclaimed 200W RMS we could barely hear things in the lower settings and by the time the music/game/film was pumping we'd run out of ways to turn it up. You would imagine that something sporting a large THX logo would make your neighbours weep. As it is it's plenty loud enough for its position in front of you but it wont have a second life as a room-filling party machine. All of which pales in comparison to the hideousness of that bass dial.

In the central position, as we've said, it's fine. Turn it up for those pounding four-on-the-floor moments and it doesn't seem to add much bass at all, if any. Curious. By no means is it as curious as turning it the other way. If you move it a hairs breadth down from the central position it's as if the bassist and drummer have been muted. No we're not resorting to the hyperbole of hack journalists. It really is like an on/off switch for any frequency below Minnie Riperton. Quite how nobody in the R&D department noticed this we don't know.

So it's built really well, not ear-burstingly loud but plenty loud enough for anything below having a party and, as long as you promise to never touch that bass dial at all, the sound profile is absolutely spot on. Just a shame about the bass dial being wired up to the worlds most over-eager low-pass filter.

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

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
