Logitech Z-2300 Reviewed
From a fantastic company well-known for keyboard and then mice production into a dependable multimedia audio trademark, Logitech has absolutely performed remarkably in the present years. While their designs don't deliver audiophile-quality performance, or characteristics of such, they certainly provide reliable, easy-to-use alternatives for the set-it-and-forget-it users that occupy a significant part of the computer and gaming market.
The capability of the Z-2300 at a hundred and then ninety-nine dollars (MSRP), includes 2 hundred watts of RMS Power, eighty watts RMS into eight ohms, at 1 kilohertz, using a ten percent Total Harmonic Distortion (THD) for the satellites and a hundred twenty watts RMS unto eight ohms at 100 hertz and then ten percent THD for the subwoofer. Logitech claims a signal to noise ratio of more than 100dB at 1kHz along with a frequency response of 35 Hz - 20 kHz (albeit without +/- dB spec, which really tells the tale - the system might technically play up to 20kHz, but if you can't hear it, it does not do much good). Buyers should bear in mind that audio specs rarely stand for real-world conditions; they merely provide a brief snapshot of a product's performance under stable conditions. Once you press "Play" and the material begins making demands on the product, the actual specs usually differ.
The Z-2300 can also provide a valid THX certification, meaning that it was able to get authorized by passing a couple of specs which other designs could also pass, without paying Lucasfilm. Although, the mark indicates much when it comes to marketing, particularly in desktop audio's small-speaker world.
The satellites, that are 6.75 inches in height, 3.5 inches in width, and six inches in depth, utilize 2.5 inches of refined lightweight aluminum phase plug driver that also comes with a top port. As the sole driver on the satellites, the phase plug driver should reproduce all the high and mid frequencies ahead of the woofer takes over. In comparison to dual driver designs, this seems to be harder. The 11-inch wide, 11-inch tall, and 15-inch deep subwoofer also engages an 8-inch long-throw ported woofer.
Setup and Operation
As with the majority of Logitech products, you'll find set-up easy. The remote control of Z-2300 is outboard wired and comes with a System Volume knob. If your source outputs using a single stereo mini-plug (as do most computers and MP3 players), simply plug the remote's 3.5mm cable into your source's audio output. If your source outputs using a pair of stereo RCA plugs, Logitech offers an adapter to convert both of these plugs into a mini-plug for link to the remote. Then plug the remote's D-SUB connector into the back of the subwoofer, making sure to line up all the pins just before pushing in the plug (they can bend and break easily). After placing the two satellite speakers, connect them to the back of the subwoofer. Conclusively, plug it to the wall( the subwoofer).
Activate the subwoofer's power switch right after making sure that the source is switched of. There must be some blinking light on the remote control's Power LED. Push the "Play" button on your source, then you're done. Utilize the volume knob of the remote control to alter the volume and the subwoofer knob to alter the bass output. You can also utilize the Power/ Standby button on the remote since it's easy to use this and also you won't have to switch the unit on and off through the subwoofer's rear switch. Since the remote's headphone jack mutes the main system instantly, it is excellent for effortless headphone hook-up, whilst it still provides volume control with the usage of the master volume knob. Nonetheless, the short hardwired cables, on both the remote and satellites, of Z-2300 may be challenging on the setup process and may even give you limited placement options.
Sound
The Z-2300 is able to play loudly that is good for movies and games. The subwoofer is a quite good package, albeit the forward-firing woofer would mean that you willhave to search for a place where a leg won't block it and the side-firing port. The subwoofer can manage boosts in the subwoofer volume knob, however in extreme situations, it clips a little and also distorts. Overall, the subwoofer presented good performance, considering the price. The overall excellence of the remote's volume controls may be improved, however when considering the price, it's hard to argue.
The satellites provide a bag of combinations. The sole driver can't reproduce the frequencies' whole range sufficiently, bringing on some rolled-off high ranges as well as an average midrange. Between the satellites and subwoofers, there exists an apparent sonic gap that signifies a lower crossover point that the satellites just cannot manage. The satellites also exhibited fairly directional characteristics, meaning that since they pointed away from the hearing position, the sound degraded significantly. When assessing the overall sound quality, sound staging and imaging, better think about these things.
High Points
- The Z-2300 plays loud and definately will do your movies and games justice. Considering the increase in attraction of movies by the download from the likes of Apple's iTunes as well as other sources like Hulu, you are most likely going to need better speakers for the computer.
- Considering the size and cheap price, the subwoofer is amazingly good.
- Logitech's Z-2300's seems rather decent in size and appearance as compared to its cost. The speakers look pretty good.
- The remote device provides an easy touch; with high quality headphone jack.
- The RCA connection adapter lets you fit the gaming consoles easily.
Low Points
- The Z-2300 tends to leave audiophiles in search of more when it comes to musicality upon comparison of the system to ordinary bookshelf speakers. Bookshelf speakers do not nicely fit on your own table alongside a big old 24-inch LCD monitor, however , if there are audiophile needs on your desk, then better stick with this gear and pay the necessary prices.
- The short, hardwired cables of the remote control and especially the satellites reduce placement options.
- The subwoofer's output is not going to turn completely off, even at the lowest volume setting, which designed for some difficult times when wanting to set up the system.
- The device does not provide a second input which is supposed to be very significant.
Conclusion
At a low price, the Z-2300 offers several advantages. Good quality of sound for games and films is provided by the Logitech system along with other significant features and appealing aesthetics. Today, you need a good set of speakers for your computer understanding that online downloads are already extremely popular among myriad of users, and Logitech Z-2300 might be the best deal for you. logitech z-2300
