Logitech Speaker System Z623

I love these things I got them from Best Buy for $100 and It was worth it. These are THX computer speakers meaning that you can watch movies very clearly and more balanced. They allow for you to connect them to a computer monitor and out put at any display it's showing which is really nice. Also have a port for input and output for your headphones. Pretty great for $100

So I have owned these for 8 months now. The bass makes me melt. Its awesome. I LOVE IT. my windows shaking. The stuff on my table shaking. Its awesome. When I show my friends they don't expect whats to come when I turn that bass dile all the way up. HOLY. its fun. I love playing games while I lsiten to these bad boys. Comes with 2 speakers and a sub and for $120? WORTH IT. If you are looking for amazing bass and overall good sound quality. Might as well buy these. They rock. I'm new to headfi but take my word for it. I got my buddy to buy this. He loves it. I like to make the house shake. That was my goal since when my dad watch's movies on his 70" T.V downstairs with a $2000 surround sound system, which is right below me. This drowns out that bass with mine buahahah. Anyways buy it its worth it. 

Firstly I was running some old Panasonic speakers (about 20 years) but I've always wanted more bass. Yes, I'm a basshead. After a lot of research of what's available for purchase in my country I settled down with Logitech Z623, well, mainly because of the subwoofer. First day I got them I didn't really like them, but as I got more used to their sound, they fitted into my life pretty well.
 
Highs
Not over-exposed or anything. Sounds balanced out and doesn't hurt my ears even on high volumes, though not enough for studio use (as I also have a studio, I know a lot). It has a "nearly dedicated" tweeter. All in all 9/10.
 
Mids
That's where these speakers lack quality. It just LACKS MIDS. It's very unbalanced, guitars, vocals sound dim.
 
Lows
Bass is just what you'd expect with that big of a sub. It's very good. Nearly splendid. Though I'm running them off an amped pc output on 50% volume set on windows and around 60% of volume on logitechs subwoofer sounds distorted and smells like burning.
 
Lastly, It's a decent pair of speakers for daily use. You won't be disappointed.

A friend recommended these speakers for me. They work great if your room is not too big. The bass is pretty good and they are pretty cheap. Good bargain for the price. I would prefer more treble but for the money I think it is fine. I am thinking of getting some tweeters to work along with these Logitechs and have the highs come more to life.
 
Lalo

The Logitech Z-2300 were a decent pair of speakers. A few friend had them and  I was enthused when they played them. Also they were made at a time where it's said that fitting the most quality into  this range of computer speakers was the goal of many manufacturers (*Klipsch ProMedia 2.0, from said time period, still selling*) Logitech has and ugly side we all know too well. In current days it would seem keeping up with the neighbors and releasing products made cheaply with false claims is the route taken here.
 
The highs and mids are a mixed, muddy, bloody mess, despite allegedly using the same tweeters as the Z-2300. The sub is OK, it gets boom and muddy when turns to high (aside  from the volume itself) On top of the ikky sound they took out the separate control pad and put all the knobs on the right speaker, so you can't 'stow' them or put the right speaker out of reach. To make matters worse, there is no externally present slow blow fuse. The fuse is inside the *smaller* sub so if that blows, your down an entire set (happened to me  )
 
If (*IF* and only ifffff) yo need a  quick fix then be my guest though for the ~$150 range there IS better.
