{"product_id":"eminence-alpha-3-32-american-standard-411539","title":"Alpha 3-32 American Standard","description":"\u003ch3\u003eThe \"American Standard\" Series: Eminence's Efficiency-Oriented Approach\u003c\/h3\u003e\u003cp\u003eWith the Alpha 3-32, Eminence offers a small-diameter speaker from the \u003cstrong\u003eAmerican Standard\u003c\/strong\u003e series, a family designed to provide reliable and consistent solutions for speaker integration. This model emphasizes ease of implementation, performance stability, and manufacturing aimed at real-world use, whether for repair or custom system design.\u003c\/p\u003e\u003cp\u003eIts 3-inch format and high impedance make it a unique choice in a range often dominated by 4, 8, or 16-ohm versions: the Alpha 3-32 clearly targets multi-driver configurations, mini satellites, or modules where multiple emission points are desired without complicating amplification.\u003c\/p\u003e\u003ch3\u003eIntended Uses for the Eminence Alpha 3-32\u003c\/h3\u003e\u003cp\u003eThe Eminence Alpha 3-32 is aimed at designers, integrators, and DIY enthusiasts looking for a \u003cstrong\u003ecompact full-range speaker\u003c\/strong\u003e to enhance presence, intelligibility, and definition. Thanks to its declared usable frequency range up to 20 kHz, it can suit systems where the use of a tweeter is minimized or for nearfield sound solutions focused on mid-high frequencies.\u003c\/p\u003e\u003cp\u003eIts \u003cstrong\u003enominal impedance of 32 ohms\u003c\/strong\u003e is particularly interesting if you plan to assemble multiple identical speakers: this allows optimizing series\/parallel connections while maintaining an overall load compatible with the intended amplification. This is a typical advantage for compact multi-speaker columns, certain soundbars, or multi-point modules seeking even sound distribution.\u003c\/p\u003e\u003ch3\u003eDesign, Materials, and Key Integration Points\u003c\/h3\u003e\u003cp\u003eThis model combines a \u003cstrong\u003epaper\/poly sandwich cone\u003c\/strong\u003e with a \u003cstrong\u003epoly surround\u003c\/strong\u003e, a choice appreciated for balancing lightness, mechanical strength, and consistent behavior in the midrange. The frame is made of \u003cstrong\u003estamped steel\u003c\/strong\u003e, while the \u003cstrong\u003eferrite magnet\u003c\/strong\u003e contributes to a proven construction, suitable for environments where robustness is paramount.\u003c\/p\u003e\u003ch4\u003eCooling and Control: Vented Pole Piece with Flux Cap\u003c\/h4\u003e\u003cp\u003eThe Alpha 3-32 features a \u003cstrong\u003evented pole piece with flux cap\u003c\/strong\u003e, designed to promote heat dissipation and improve operational stability. Coupled with a \u003cstrong\u003ecopper\u003c\/strong\u003e voice coil and a \u003cstrong\u003epolyimide\u003c\/strong\u003e coil former, this assembly aims for good endurance during prolonged use while maintaining dynamic response.\u003c\/p\u003e\u003ch4\u003eUseful Parameters: Design Consistency and Tuning Ease\u003c\/h4\u003e\u003cp\u003eWith a resonance frequency (fs) declared at \u003cstrong\u003e117 Hz\u003c\/strong\u003e and a usable frequency range indicated from \u003cstrong\u003e150 Hz to 20 kHz\u003c\/strong\u003e, this 3-inch driver is typically intended to work from the lower midrange upwards, depending on volume, enclosure type (sealed or vented), and sonic goals. The manufacturer also states that mounting in both \u003cstrong\u003esealed\u003c\/strong\u003e and \u003cstrong\u003evented enclosures\u003c\/strong\u003e is \"acceptable,\" providing some flexibility during design.\u003c\/p\u003e\u003cp\u003eFinally, its mounting data (diameters, drill holes, front\/rear gaskets) facilitate clean integration into baffles and help ensure airtightness, an important factor when working with small volumes where even minor leaks can alter system behavior.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical
