The 120 oz magnet and heavy steel basket keep cone motion controlled through deep transients, while the dual 4Ω voice coil and 5-way terminals allow flexible wiring for dual-woofer or single-woofer configurations. The cone and surround construction—UV-treated non-pressed paper with EROM foam—resists wear in automotive environments, extending life under heat and sun. Enclosure options include a 14\"H x 16\"D x 16\"W ported design with 14.05 sq in port area for deeper bass, or a 1.62 ft³ sealed box for tighter, more controlled response. This makes it a strong foundation for a GTX124H Series system in a wide range of vehicles.\u003c\/p\u003e \u003cbr\u003e \u003ctable width=\"450\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"86\"\u003eSize\u003c\/td\u003e\n\u003ctd width=\"364\"\u003e12\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"86\"\u003eWatts RMS\u003c\/td\u003e\n\u003ctd width=\"364\"\u003e600-800\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"86\"\u003ePeak Power\u003c\/td\u003e\n\u003ctd width=\"364\"\u003e1600\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"86\"\u003eCone\u003c\/td\u003e\n\u003ctd width=\"364\"\u003eUV Treated \/ Non-Pressed Paper\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"86\"\u003eVoice Coil\u003c\/td\u003e\n\u003ctd width=\"364\"\u003e2.5\" Dual 4 Ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"86\"\u003eSurround\u003c\/td\u003e\n\u003ctd width=\"364\"\u003eEROM Foam\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"86\"\u003eMagnet\u003c\/td\u003e\n\u003ctd width=\"364\"\u003e120oz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"86\"\u003eTerminals\u003c\/td\u003e\n\u003ctd width=\"364\"\u003e5 Way Binding Push Terminals\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"86\"\u003eBasket\u003c\/td\u003e\n\u003ctd width=\"364\"\u003eHeavy Gauge Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"86\"\u003eTinsel Leads\u003c\/td\u003e\n\u003ctd width=\"364\"\u003eWoven Round\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"86\"\u003eX-Max\u003c\/td\u003e\n\u003ctd width=\"364\"\u003e15mm with 10mm Top Plate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"86\"\u003eSPL\u003c\/td\u003e\n\u003ctd width=\"364\"\u003e88 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"86\"\u003eFS\u003c\/td\u003e\n\u003ctd width=\"364\"\u003e36Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"86\"\u003ePorted Box\u003c\/td\u003e\n\u003ctd width=\"364\"\u003e14\"H x 16\"D x 16\"W \/ 14.05 sq. in.
