HDX 6x9\" coaxials?\u003c\/strong\u003e\u003cbr\u003e\nA: The HDS is SoundQubed’s entry-level 6x9\" — paper cone, 60W RMS, and a Mylar dome tweeter. The HDX-CX69 steps up to a glass fiber cone, 120W RMS, 92 dB sensitivity, and a neodymium tweeter for significantly more output and clarity. The HDS is the smart budget choice; the HDX-CX69 is for builds that demand more.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What amplifier should I pair with the HDS 6x9\"?\u003c\/strong\u003e\u003cbr\u003e\nA: The HDS 6x9\" handles 60W RMS \/ 180W max at 4Ω. The SoundQubed S4-100 (100W x4) is a perfect match for a daily driver build. Set your HPF at 80 Hz for best results and driver protection.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Do I need a separate tweeter or crossover?\u003c\/strong\u003e\u003cbr\u003e\nA: No — the HDS 6x9\" is a \u003cstrong\u003e2-way coaxial\u003c\/strong\u003e with an integrated \u003cstrong\u003e1.65\" Mylar dome tweeter\u003c\/strong\u003e. No separate tweeter or passive crossover is required — just connect to your amplifier and go.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Are these sold as a pair or individually?\u003c\/strong\u003e\u003cbr\u003e\nA: The HDS 6x9\" is sold as a \u003cstrong\u003epair\u003c\/strong\u003e — two speakers and two grills are included.\u003c\/p\u003e","brand":"SoundQubed","offers":[{"title":"Default Title","offer_id":49849729745124,"sku":null,"price":89.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0842\/2522\/9028\/files\/2__27129.webp?v=1789257227","url":"https:\/\/www.12voltoutlet.com\/products\/soundqubed-hds-series-6x9-coaxial-3-way-speakers-pair","provider":"12 Volt Outlet","version":"1.0","type":"link"}
