Logitech Z623 400 Watt Home Speaker System, 2.1 Speaker System - Black

What a Weapon! Flawless Sound Quality throughout the entire volume range! Definitely THX certified kit! The Sound Quality and Bass is incredible! You will not be disappointed! Great for Music, Videos and Gaming.

I've had 2 sets of these over the years so I feel very qualifed to review.. These sound great and produce serious sound levels enough to make neighbours hate you... The separate bass control knob is very important - you need to adjust this depending on the music and how your room sounds. I have no doubt these hold up against big brand speakers like Bose costing twice as much. I bought a second set because my first one was fried by a voltage brown-out when I was abroad in a rural location. Apparently these use a digital amplifier and the power supply is built in, which is hard or impossible to repair from such damage, so use a surge protector! I am giving only 4 stars because both sets I have had have the same issue. The volume control knob becomes crackly over time. Turning it around a few times seems to clear it up but this is not OK. Also, the cable connecting one speaker to the subwoofer uses a very thick, stiff and quite short cable which is fixed to the speaker. This needlessly limits your speaker placement options. Logitech should supply an extension cable.

Bought my Logitech Z623 last year albeit 2nd hand. Excellent when it works fine, very loud and ace for mixing etc. Trouble was a few months later the sound would flicker badly then the bass stopped altogether. I opened up the sub box and the sub is fine but the subs amp is not. Cheap shoddy circuit board within the sub box so be warned. Small speakers still work but nil bass. Bought another used sub box from europe but this has different inputs on the back of it. The uk model has dvi female on the back and german model has dvi male. Speakers i have are male so male to male will not go unless their homosexual which they arent. So had to mess around and find a female to female (lesbian) adapter. These subs are supposed to be 120w and the whole system 200w rms but the amp in it doesnt last if you have it loud.

No one in their right mind would buy this at this price. There are dozens at half the price and even if they only last half the time you can get a new one at half the cost.

If the speaker goes into standby, it needs to be turned off and the again on, or you won't get any sound, even if you start for example Youtube.

حاولت إجراء إرجاع رسمي، واكتشفت أن تكلفة شحن الإرجاع تقع بالكامل على عاتق المشتري ("I'll Ship and Pay") دون أي ملصق شحن مجاني، رغم أن سبب العطل هو نقص معلومات من طرف البائع/الصفحة وليس خطأ من جهتي. كما لاحظت لاحقًا ملصقًا تحذيريًا مطبوعًا على عبوة الشحن نفسها بعد الاستلام يفيد بعدم استرجاع المبلغ في حال التلف الناتج عن فرق الجهد — وهو تحذير جاء متأخرًا جدًا، بعد إتمام عملية الشراء والدفع بالكامل، وليس وقت اتخاذ قرار الشراء. الخلاصة: جودة الصوت والبناء ممتازة فعلاً حين يعمل الجهاز بشكل سليم، لكن تجربة الشراء من هذا المصدر تحديدًا كانت مكلفة ومحبطة بسبب نقص شفافية حول متطلبات الجهد الكهربائي، وسياسة إرجاع غير عادلة تُحمّل المشتري وحده تبعات نقص في المعلومات لم يكن بمقدوره معرفتها مسبقًا. نصيحتي لأي مشترٍ آخر: تأكد من جهد الجهاز بنفسك قبل الشراء من أي بائع يشحن من خارج المملكة، ولا تعتمد على اكتمال صفحة المواصفات.

el artículo llego bien antes de lo previstos y al ponerlos a funcionar pues muy bien sonido como se esperaba y poco tengo mas que decir buen potencia es como me imaginaba son de los buenos de logitech muy satisfecho

Tonight, I got a scare -- these speakers, which I've loved for the short time I've had them (i.e., since mid October), sounded tinny and thin. I checked the connections. I rebooted the computer. Still tinny. Then, it occurred to me (my mind must be slowing down) that no speaker problem would speed up the music. Aha! It was my Enounce program -- a program that lets you listen to audio at up to 3 times its normal speed. I had it set for 2X normal speed after listening to a tutorial by a drawling presenter. I set it back to 1X the recorded speed and, voila!, the music was back. So, since I had found myself more than willing to write a damning review of the longevity of these speakers, I felt it only fair to write a review of just how good they are. So, that's why I'm adding yet another 5-star review of these things. What's not to love. Their sound is outstanding. You can set the bass levels to where you want them -- and the bass is not that terrible boomy stuff of boom boxes and miserably made speakers. It is, rather, crisp and unobtrusive. The mid-range is clear. And, for all my aged ears can still discern, the highs are there. (Alas, when younger, my hearing test for the Air Force had my hearing right up there with dogs. Well, not quite. I couldn't hear a dog whistle. But, I could hear the highest tones that the hearing test provided making my line slightly above the chart. Now, I know, some of the higher frequencies are lost on me.) Volume is no problem. While those who are deaf and those who aspire to become deaf may not find the higher volumes sufficient, most who would rather hear music rather than test their pain tolerances should be quite happy with these. Could they be better? Well, perhaps I might welcome both: a) left-right balance controls and b) a remote. The former can be handled by software that's already on your computer if you go hunting for it. The latter is for those who build up a heckuva lot of static electricity while sitting on a cold winter's night. I'd rather discharge it on the remote than risk zapping the speakers. That age thing, alluded to already you may have noticed, might at any time get me to forgetting to discharge any built-up charge on the case of the computer instead. You could spend a lot more and do a lot worse (sorry Bose). But, why? My musical preferences: jazz, classical, some folk, and a handful of individuals who fall into none of these categories. So, if you're interested in hard rock or the alleged thoughts of rap "artists," you may well want to move onto another review. With computer speakers, it has been my experience that few last for all that long. But, these do appear to be made well. So, I'm optimistic that they will continue to perform well for some time to come. ========================================================================== Unrelated tip: That Enounce program is a freebie and well worth installing if you take courses or listen to tutorials or simply want to race through ads that won't allow you to skip them. It does a good job of speeding things up without making the voices sound like Mickey Mouse after he inhales helium. ========================================================================= Another unrelated tip from John Templeton (a legendary investor): The fastest way to double your wealth is to double your gratitude. Without gratitude, there is no possible perception of wealth.

Bought the Logitech Z623 on discount at S$149. This is an older legacy model but the sound quality remains top notch. The bass is superb. All the controls/knobs being located on the right speaker makes it very convenient to adjust things - even the amount of bass. This is more practical than the newer designs where Logitech provides a separate hockey puck for adjustments, or other models where the bass knob is located on the subwoofer.
