Logitech Z623

The Z623 and Z625 are both powerful 2.1 computer speaker systems delivering 200W of total power and featuring a bass reflex subwoofer design with large 7-inch bass elements. The Z625 offers more versatility with two 3.5mm inputs and a digital optical input, compared to just one 3.5mm input and no digital inputs on the Z623. While the Z625 is lighter overall, its front speakers are larger but shorter in height compared to the Z623’s more compact front units. Both models have the same frequency response range and include built-in speaker controls and headphone output, making them quite similar in sound performance. Choosing between them depends on whether you prioritize additional input options and a slightly more compact subwoofer or a more compact front speaker size.
