These original Portogram speakers are a must-have for any pro audio equipment enthusiast. They feature one Celestian G15-50 and one Celestion speaker, providing a high-quality sound experience for any musician or DJ. The connectivity is wired, ensuring a reliable and easy-to-use setup. The brand of these speakers is Celestion, and the model is G12s50. Instantly recognisable by its green magnet cover, the Greenback shaped the sound of British’70s blues-rock. Warmth and woodiness are the essential characteristics of its sound, with the ability to respond instantly to the most subtle dynamic changes. But the Greenback still has all the brightness and punch you need to cut through the rest of the band. Whether you’re a professional or a hobbyist, these speakers are sure to impress. Both speakers have been tested and both play fine, however it feels like they made need to be refurbished by a speaker specialist as when you increase the volume towards max they start to distort. If you have any questions please do ask before placing an order! Thank you for checking out this listing.
