Engineered as a direct replacement component, this driver maintains the acoustic signature and thermal characteristics that touring engineers and system integrators depend on for consistent array performance across multi-cabinet hangs.\u003c\/p\u003e\u003cp\u003ePaper cone construction paired with a 2.5\" voice coil provides the mechanical compliance and power density required for line array applications where multiple cabinets operate in close acoustic proximity. The 8-ohm impedance integrates seamlessly with KLA12 amplifier modules and DSP presets, eliminating the need for system recalibration after component replacement. This raw frame driver enables in-field repairs without returning cabinets to depot facilities, reducing downtime for rental houses and production companies maintaining active line array inventories.\u003c\/p\u003e","brand":"QSC, LLC","offers":[{"title":"Default Title","offer_id":52451902718136,"sku":"201052","price":163.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/201052_QSCAUD-XD-000004-00_ALT01.jpg?v=1782829933","url":"https:\/\/soundpro.com\/products\/qsc-xd-000004-00","provider":"SoundPro","version":"1.0","type":"link"}
