Review: Solid speakers! - Not bad at all! After upgrading from a 5.1 Onyko to a Sony 7.2 I needed another pair to add on. I currently have JBLs and these didn’t sound too far off from those. In terms of build quality they are almost identical. The highs and mids are clear using 14 gauge speaker wire. Don’t hear any distortion, muffling or static. Having needed these for just that it, gets the job done! They really helped add that extra dimension of sound offered by a 7.1 or 7.2 setup w/ 360 audio or Dolby Atmos. Little to no bass but these aren’t built for that. That’s what a subwoofer is for. So if you need to replace a pair of satellite speakers or add on to a current setup but don’t wanna break the bank, these do great! Obviously if you’re an audiophile you’ll wanna spend some extra coins. But even then, I think at this price point they would appreciate what these little guys can do.
Review: What a great great speaker at this price point - Wow is what I have to say about these speakers. I ordered these having little faith in how good they were considering the price point. I was blown away how good these were. First off, I was expecting a plastic speaker box, nope solid wood. Pressboard but its wood. Wood vs Plastic.. Wood always has better acoustics. I can turn up the volume up pretty high and I do not get any distortion or any vibrations (as you would with plastic) I bought these to use with a cheap Yamaha S202 basic receiver in my bedroom. Mostly to watch TV in bed at a low volume using the A/B speaker selection so a set of speakers near the head of the bed would activate. I bought two sets of these. One for the front and one for the back. They work perfectly for this application, voices and music are clear and can be heard at low volumes. My only real complaint is that there's virtually no bass at all with these. I don't mind too much with my bedroom TV application, but would not work where music was the primary source (unless you don't listen to music with any bass). But its not really a good complaint because these work fabulous as satellite speakers with a 5.1, you would just need to add a seperate bass kicker. Overall, these are a great buy for price point, and I will probably buy a few more to finish out my 'whole house' audio system and use these speakers in each room.

## Questions & Answers

**Q: can you use a split copper speaker wire to connect from an old school amplifier to the speakers?**
A: Yes if you have the spring stab type connector on the amplifier + and -. That is what is on the back of the speakers. You just need to strip back bare wire for the connection. If your amplifier has what they call RC connectors. They are usually Red + white - just plug them in at the amp. Then you only have to strip back a connection at he speakers they too are red + and white -.

**Q: can these speakers work with the audio-techica at-lp60 usb turntable**
A: Answering late...for others needing help - you need active speakers to connect directly to the turntable otherwise you will need to connect the turntable & these speakers to an amplifier.

**Q: Do these have a screw hole in the back for mounting on a speaker stand?**
A: Yes and they come with wall mounting brackets for hanging the speakers on the wall.

**Q: what do they sound like listening to music, mostly rock & jazz?**
A: They are great for any music. I have them connected to my surround sound system and play movies , music, etc.  They can take a lot of power too, I was really impressed by that.

### ⭐⭐⭐⭐ LOUD
*by B***Y on November 3, 2025*

cant complain about the price, surprising part is they are LOUD and they are not just focused on the highs. it's very much a full-spectrum driver. of course the speaker is so small you're not going to get any bass out of it, but it does an admirable job at spreading out the sound. i'm not sure their preferred use - maybe rear surrounds. i have them as directional support for some bookshelf speakers just for fun and i like the results. they feel and operate very solidly, i have to laugh at the 200W rating but they really dont rattle and they will push a lot of air!
