    When you need loud sound/bass look no further

    Great build quality decent price and connection options with cables included. Other reviews are on the money. These are not meant to be played at low levels but are insane at higher levels.

    Bought a 2nd set, Great for the price, can run 2 sources

    I had a set of these for years and was very happy with them. The bass is rich and punchy and well balanced and the controls are great. After years of abuse I ruined the cable connections because I kept pushing against them with my foot while scooting a heavy recliner back, not realizing I was pushing directly against the cord connections. I'm honestly surprised they lasted that long considering what I was doing to them. My dogs would also use the subwoofer as a stand to look out the window. I'm not sure why but I replaced them with set of slightly cheaper speakers, the Klipsch ProMedia 2.1 THX

    Powerful sound and great for movies

    I’m really impressed with the Logitech Z625. The sound is powerful and clear, and the 7-inch subwoofer delivers deep, strong bass that makes movies and games much more immersive. The THX certification definitely shows, especially during action scenes and music.Setup was easy, and I like having multiple input options. The speakers also feel well-built and solid. Overall, this is an excellent 2.1 speaker system if you want powerful sound, deep bass, and great grip on the audio experience without spending a fortune.

    Far Better Than I Expected!!

    I've been listening to this system for a little over one month.For MANY years I had used the Boston BA745 2.1 speaker system with my computers. It was a system Gateway supplied with their computers (yes, that was long ago in a computer galaxy far, far away). They finally reached the end: the sub woofer would cut out, the left speaker volume would cut in half, wires had to be jiggled, subwoofer kicked, etc.I researched for months to find replacements. I asked for recommendations on Facebook. I read review after review on the internet. I narrowed it down to either the Klipsch ProMedia 2.1 THX sy

    Worth getting for upgraded desktop audio

    Here’s the thing. Everyone wants to claim they’re an audiophile and the best at reviewing every product they touch. I’m not going to do that. I’m just a random internet person who wants others to benefit from my experience so you can make a choice a bit easier. Let’s cut to the chase to avoid the giant wall of text..If you’re coming off of cheap speakers, these are an excellent choice. If you already have a quality speaker set these probably aren’t worth a “side-grade”. Paired with the Bluetooth adapter from Logitech (others have noted that there are 3rd party cheaper ones) I’ve enjoyed this s

    Quality in all aspects

    Now I’m not a total audiophile but I do like my quality and clean sound, I’ve put these to the test specially with bass and it always came out crystal clear! It’s easy to hookup even for extreme beginners and always recommend the optical over audio. As far as how loud it gets, zero complaints and I like loud
