**Change:** "扬声器" → "音箱" (line 2). "扬声器" is the generic term for speaker drivers; in the context of professional stacks and cabinets, "音箱" (cabinet/enclosure) is the more precise and standard term in B2B audio trade copy. Also removed the extra non-breaking space before the parenthesis in the final item for consistency.
