Faint Hiss From Logitech Speakers

Full disclosure, these are my first audio monitor speakers so I have no direct comparison. That said, I do usually use my home theater audio to check final products and edit with Beyerdynamic DT700 ProX headphones so I feel like I know good sound when I hear it. The difference in using my iMac audio for reference when editing vs these is night and day. I can't believe I waited so long to invest in proper audio monitor speakers. I think the most notable thing about these is how full they sound. They are not large speakers but they provide sound that seems to come from inside my brain. great balance between lows and highs. the bass is definitely defined without being muddy or drowning out mids. trebles are equally clear and easy to notice without any harshness. The only negative aspect with these is the subtle hiss they emit when turned on. I'm told this is normal and it's just what you get at this price point for powered audio monitors. After only two weeks I'm getting used to it and I turn off the speakers when not in use. When using them actively, the hiss is too quiet to hear and doesn't interfere with my work, but it's worth knowing.

I replaced my active monitors with the ELAC speakers and a Yamaha integrated amplifier. Since the ELAC has coaxial arrangement of tweeter + midrange, I felt it would work fine for near field listening. I'm very happy with the result. With nothing playing, the combination of amp with passive speakers has no background hiss. My old monitors had audible hiss and non-defeatable auto-shutoff unless the playback was kept sufficiently loud. I'm using an RME ADI-2 DAC feeding the Yamaha amp. I chose ELAC's Satin White with Oak Sides to escape the all-black look of my old monitors.

The sound you are getting for your money with these is spectacular. If there's any downside it's that they can sound phenomenal with the right listening position and maybe not quite as phenomenal if you site somewhere else. The vertical alignment is particularly noticeable. Luckily the rubber foot makes it easy to adjust the vertical angle, not something you are going to get from most monitors or bookshelf speakers that are in prismatic cases. The only other slight con may be some hiss if you stick your ear right in the tweeter, but if you sit a meter away you can't hear it. I turned the sensitivity all the way down and that also reduced the hiss. With pro-level sources (my reference level is +13dBu) you don't need the gain these speakers offer.

Remember when you used to sit in class, and everyone was supposed to be working on a written assignment? The room would be mostly quiet, with the scratching of pencils on paper... and then you'd hear the intercom switch on. You'd get a couple seconds of faint hiss, followed by a slightly distorted announcement about the lunch menu, then the system would click back off. THAT is exactly what this amp is designed to do - amplify things to a decent level at very low cost (therefore, the noticeable hiss). I built a quirky little custom guitar speaker cabinet with a 3x3 array of 4.5 Jeep Cherokee factory speakers. I was going to use it as an extension cab, then found this little gem. I figured I'd turn my cab into a full-fledged combo. After rewiring the speakers to 2 4-ohm stereo sets, I plugged this amp in, hooked up my guitar (through the mic jack), and the rest is history. The sound is of acceptable quality while at normal practice / listening volume. When I crank it up to about half way on the mic knob, the loud hiss starts (even with all knobs at 0 volume on my guitar and pedals). 10% THD is VERY high compared to most guitar amps, but it was a great deal, compared to buying an AC-to-DC converter and using a car amp which was my original plan. You simply won't find a little amp that does what this one does, for any cheaper.

This 2.1 system by far is the best set-up I have ever owned from Logitech. Speakers are crisp and clean, lows are low and highs or high. I use these while gaming, as my PA speakers when I'm making my style of music(electro house) on FLStudio and mixing while using my DJ Pioneer DDJ-800 controller. Thanks Logitech for making such a fine product, and never discontinue these great speakers. Thanks

You can't beat the quality of these speakers for the price. Nice full sound. Logitech does it right!

Audio produced is very clean with no hiss. This is our go to amp now!

I replaced my passive Logitech computer speakers with a pair of the Audioengine A2+ speakers and a small 6.5 powered subwoofer. This is a great combination for listening to streaming videos and music in my small office. I use the USB input for the signal from my computer and the RCA outputs to send a signal to the powered subwoofer (Acoustic Audio PSW-6 purchased separately). Shown in the pictures on the Audioengine DS1 stands. The only con is the volume knob is on the back. I would purchase them again.

I bought one 47 TV few weeks ago but there was something missing, I felt so. Then I bought Logitech speakers and now my world is complete. This product is amazing. Sound quality is good. It doesn't occupy much space. Overall, the product is satisfactory in all terms.

The sound quality of this Logitech S-150 speaker system is SUPERBE. The speakers sit 28 in front of me, the pitch of the HIGHS & LOWS produced by the speakers is far greater than what I expected for such a small speaker system. I would highly recommend this speaker system.
