Great value speakers for a beginner audiophile
Size: 4” Woofer
Fantastic sound quality to my ears, got these used “mint” for 179 and that was a steal, they were never even opened. They feel solid and well made, they’re heavy for the size which makes them feel of a higher quality. Very happy with my purchase
