By combining a traditional speaker (Dynamic Driver) for the bass with a specialized \"Balanced Armature\" for the high notes, it created a sound that was wider, sharper, and more energetic than anyone expected for the price. It’s the \"Old Guard\" of the Vault—tried, tested, and legendary.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli dir=\"ltr\"\u003e​\u003cb\u003eThe Hybrid Pioneer:\u003c\/b\u003e It uses a dual-driver system to split the work.
