"Ada banyak 8" amplifier di pasar, tapi sangat sedikit Memiliki speaker mampu memberikan nada berkualitas. "Kata Anthony Lucas, Eminence dukungan teknis spesialis." 820H terdengar seperti Hampir 10" speaker dan tidak melenceng terlalu dini atau berantakan seperti lainnya 8" speaker saya dengar. Bisa Meningkatkan nada dalam setiap penguat, dan whos pertama 8 " speaker yang pernah saya dengar bahwa saya pertimbangkan layak menempatkan dalam sesuatu seperti vintage Fender Champ."
