разница в материале корпуса
The 2s have chipboard enclosures covered in wood-look vinyl, and their cabinets have recessed front and back panels, while the 2 Signatures have all-birch plywood cabinets with wood veneer and smooth front and back panels without obvious seams.
Ну а плюшки, думаю, все те же
One of the AX-2 Signatures' greatest strengths is their rhythmic nature. They are fast, dynamic speakers that love source material like Reggae or Latin-inspired music. Cymbals, bells, drums, congas, and similar instruments are especially well treated by the Signatures, and I really enjoyed their clear and clean recreation of vocals.
