Anthony Gallo Nucleus Micro Loudspeaker (each)


These speakers are the best I have heard in the Micro class. If a small, affordable, low visibility speaker is your desire, this high resolution gem is a perfect choice.


The Size of an Orange… the Sound of an Entire Grove!

Your eyes will not believe the size, and your ears will not believe the sound. But believe it you will, because it’s true. The Nucleus Micro is Gallo's best-selling speaker for a reason - these 4” all-metal spheres deliver superlative sound, at an attractive price. The build and technology encompasses years of Gallo know-how, and the results will be music to your ears. 

Gallo's Best Selling Loudspeaker!

The Nucleus Micro is Gallo’s best-selling loudspeaker, and is sold at more than 150 dealers (in over 40 countries) worldwide. We helped introduce the world to the round speaker, and we’ve spent the last several decades further perfecting (and patenting) this technology. 

The Nucleus Micro is one of our proudest achievements, because it delivers high-end sound at an entry-level price. If you’ve thought about high-end audio, we’ve got your show tickets right here. And this little 4” steel-housed number has been garnering accolades for more than 20 years.

They are small (literally the size of an orange), and have a dual effect on your décor – they can either be mounted to prominence (eliciting many “wow, those are cool speakers” comments), or they can vanish unobtrusively into any décor. The choice is yours.

But the sound does anything BUT disappear. Full, dynamic, and crystal clear, this little marvel will involve you with your music and movies like no other small loudspeaker, and even outperform box speakers many times their size and price. Use these as your main speakers, as rear satellites, or any combination of such. They are that good. You can also use them for desktop listening as well (they go great with music streaming services, and can also add some serious punch to your gaming rig!)
