Its 10-inch driver delivers stronger bass than the 8-inch ST model, making this 4-ohm passive subwoofer a fit for theaters, multi-zone systems, and high-end residential spaces. As a passive sub, it runs from an external subwoofer amplifier. The ST10 4 Ohm suits integrators specifying low-impedance distributed bass with greater displacement.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eThe ST10-4 is part of the James Loudspeaker ST subwoofer family, where the suffix indicates electrical configuration. The 10 indicates a 10-inch driver and the -4 indicates 4-ohm wiring suited to standard low-impedance amplifier outputs. Because it is passive, the ST10-4 requires an external subwoofer amplifier, leaving power and signal processing under the integrator's control. It is the impedance counterpart to the 70V ST10-70, which shares the same 10-inch driver but is wired for constant-voltage distribution, and it steps up in displacement from the ST8-4. Within the ST range it scales further to the ST12-4 for larger rooms. The full lineup is available in the \u003ca href=\"https:\/\/creationnetworks.net\/collections\/james-loudspeaker\"\u003eJames Loudspeaker collection\u003c\/a\u003e. This makes the ST10-4 a practical specification for low-impedance subwoofer systems needing added output.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e10-Inch Driver\u003c\/strong\u003e — A single 10-inch woofer increases low-frequency output over the 8-inch ST model.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-Ohm Configuration\u003c\/strong\u003e — Wired for 4-ohm operation to match low-impedance amplifier channels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePassive Operation\u003c\/strong\u003e — Driven by an external subwoofer amplifier for full integrator control.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eST Family Compatibility\u003c\/strong\u003e — Matches other ST subwoofers for consistent multi-zone specification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScalable Range\u003c\/strong\u003e — Specifies cleanly alongside larger ST models for bigger rooms.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTypical Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLow-frequency reinforcement systems\u003c\/li\u003e\n\u003cli\u003eCommercial AV and entertainment venues\u003c\/li\u003e\n\u003cli\u003eMulti-zone audio installations\u003c\/li\u003e\n\u003cli\u003eHigh-end residential and hospitality spaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cdiv style=\"overflow-x:auto;-webkit-overflow-scrolling:touch;\"\u003e\u003ctable style=\"width:100%;border-collapse:collapse;min-width:480px;\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px;\"\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px;\"\u003ePassive Subwoofer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px;\"\u003e\u003cstrong\u003eDriver Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px;\"\u003e10\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px;\"\u003e\u003cstrong\u003eDistribution\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px;\"\u003e4-Ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px;\"\u003e\u003cstrong\u003eOperation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px;\"\u003ePassive (requires external amplifier)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003c\/div\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eDoes the ST10-4 need an amplifier?\u003c\/strong\u003e\u003cbr\u003eYes.
