It was developed for ultra-compact, sealed enclosures and performs reliably where space is at a premium – for example, under the rear seat of many pickup trucks. The driver achieves approximately 20% greater mechanical excursion than conventional designs, thus offering a strong ratio of enclosure depth, low-end extension, and power.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Highlights\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUltra-flat mounting: 83.6 mm (3.35 inches)\u003c\/li\u003e\n\u003cli\u003ePower: 500 W RMS, 1000 W Peak\u003c\/li\u003e\n\u003cli\u003e+20% mechanical excursion compared to conventional designs\u003c\/li\u003e\n\u003cli\u003eRobust, screwless mesh grille included\u003c\/li\u003e\n\u003cli\u003eOptimized for extremely compact, sealed enclosures\u003c\/li\u003e\n\u003cli\u003eStable cast aluminum basket design\u003c\/li\u003e\n\u003cli\u003eNon-vented rear design for reduced enclosure depth\u003c\/li\u003e\n\u003cli\u003e38 mm (1.5 inch) six-layer copper voice coil for high thermal capacity\u003c\/li\u003e\n\u003cli\u003eAir Intercooling REvolution (A.I.R.) to prevent air compression\u003c\/li\u003e\n\u003cli\u003eHorizontal 8-AWG plug terminals\u003c\/li\u003e\n\u003cli\u003eScan, discover, identify\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eVariant \u0026amp; Application\u003c\/h3\u003e\n\u003cp\u003eThe MPS 250 is available as S4 and S2. Both variants are tuned for small, sealed enclosures from approx. 14 liters net and are ideal for shallow installations, e.g. under seats or behind trim panels. The centering with special support structure for spider and coil allows the magnet to be shifted further inwards – this reduces the overall height while maximizing linear excursion.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Data (general)\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSize: 250 mm (10 inches)\u003c\/li\u003e\n\u003cli\u003ePower Handling: 500 W continuous, 1000 W Peak\u003c\/li\u003e\n\u003cli\u003eImpedance: 2 Ohm\u003c\/li\u003e\n\u003cli\u003eMounting Depth: 82.6 mm\u003c\/li\u003e\n\u003cli\u003eVoice Coil Type: single\u003c\/li\u003e\n\u003cli\u003eFilter: no filter components in the subwoofer\u003c\/li\u003e\n\u003cli\u003eVoice Coil: Ø 38 mm (1.5 inches), 6-layer copper\u003c\/li\u003e\n\u003cli\u003eFrequency Response: 25 – 400 Hz\u003c\/li\u003e\n\u003cli\u003eMagnet Size (D x T x H): 134 x 55 x 36 mm\u003c\/li\u003e\n\u003cli\u003eWeight (per piece): 5.11 kg\u003c\/li\u003e\n\u003cli\u003eMagnet: high-density ferrite\u003c\/li\u003e\n\u003cli\u003eCone: Polypropylene\u003c\/li\u003e\n\u003cli\u003eXmech: 20 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eElectro-acoustic Data MPS 250 S4\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEquivalent Diameter (D): 216.6 mm\u003c\/li\u003e\n\u003cli\u003eXmax: 16.8 mm\u003c\/li\u003e\n\u003cli\u003eRe: 3.3 Ohm\u003c\/li\u003e\n\u003cli\u003eFs: 29 Hz\u003c\/li\u003e\n\u003cli\u003eLe: 3.65 mH\u003c\/li\u003e\n\u003cli\u003eMms: 234 g\u003c\/li\u003e\n\u003cli\u003eCms: 0.11 mm\/N\u003c\/li\u003e\n\u003cli\u003eB·l: 17.3 T·m\u003c\/li\u003e\n\u003cli\u003eQts: 0.48\u003c\/li\u003e\n\u003cli\u003eNs: 0.52\u003c\/li\u003e\n\u003cli\u003eQms: 5.6\u003c\/li\u003e\n\u003cli\u003eSPL: 83.5 dB\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eElectro-acoustic Data MPS 250 S2\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEquivalent Diameter (D): 216.6 mm\u003c\/li\u003e\n\u003cli\u003eXmax: 16.8 mm\u003c\/li\u003e\n\u003cli\u003eRe: 2.2 Ohm\u003c\/li\u003e\n\u003cli\u003eFs: 28 Hz\u003c\/li\u003e\n\u003cli\u003eLe: 2.67 mH\u003c\/li\u003e\n\u003cli\u003eMms: 250 g\u003c\/li\u003e\n\u003cli\u003eCms: 0.13 mm\/N\u003c\/li\u003e\n\u003cli\u003eB·l: 14.7 T·m\u003c\/li\u003e\n\u003cli\u003eQts: 0.41\u003c\/li\u003e\n\u003cli\u003eNs: 0.45\u003c\/li\u003e\n\u003cli\u003eQms: 5.3\u003c\/li\u003e\n\u003cli\u003eSPL: 82.5 dB\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eDimensions (physical)\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eA: 274.5 mm\u003c\/li\u003e\n\u003cli\u003eB: 231.6 mm\u003c\/li\u003e\n\u003cli\u003eC: 103.2 mm\u003c\/li\u003e\n\u003cli\u003eD (Mounting Depth): 82.6 mm\u003c\/li\u003e\n\u003cli\u003eE: 244.6 mm\u003c\/li\u003e\n\u003cli\u003eF: 38.9 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eEnclosure Recommendations\u003c\/h3\u003e\n\u003cp\u003eSealed – tight and precise, high energy component from 20–40 Hz:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eVb: 14.2 l net\u003c\/li\u003e\n\u003cli\u003eFc: 49 Hz\u003c\/li\u003e\n\u003cli\u003eQtc: 0.81\u003c\/li\u003e\n\u003cli\u003eOuter Dimensions (Example): W 386 mm, H 352 mm, D 160 mm\u003c\/li\u003e\n\u003cli\u003eMounting Hole (M): 232 mm\u003c\/li\u003e\n\u003cli\u003eWall Thickness: 16 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003ePanel Cut List – sealed:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eA: 386 x 352 mm – 2 pieces\u003c\/li\u003e\n\u003cli\u003eB: 386 x 128 mm – 2 pieces\u003c\/li\u003e\n\u003cli\u003eC: 320 x 128 mm – 2 pieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003ePorted – for high output, focus on 40–80 Hz:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eVb: 19 l\u003c\/li\u003e\n\u003cli\u003eFb: 35.5 Hz\u003c\/li\u003e\n\u003cli\u003eOuter Dimensions (Example): W 713 mm, H 372 mm, D 130 mm\u003c\/li\u003e\n\u003cli\u003ePort\/Inner Dimensions: Z 146 mm, P 98 mm, S 52.3 mm\u003c\/li\u003e\n\u003cli\u003eMounting Hole (M): 232 mm\u003c\/li\u003e\n\u003cli\u003eWall Thickness: 16 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003ePanel Cut List – ported:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eA: 713 x 372 mm – 2 pieces\u003c\/li\u003e\n\u003cli\u003eB: 713 x 98 mm – 2 pieces\u003c\/li\u003e\n\u003cli\u003eC: 340 x 98 mm – 1 piece\u003c\/li\u003e\n\u003cli\u003eD: 288 x 98 mm – 1 piece\u003c\/li\u003e\n\u003cli\u003eE: 495 x 98 mm – 1 piece\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eInstallation \u0026amp; Compatibility\u003c\/h3\u003e\n\u003cp\u003eThe MPS 250 S4\/S2 fits into very shallow installation locations – for example, under seats or behind side panels. The non-vented rear allows for shallow enclosure depths, and the side 8-AWG terminals facilitate wiring. A screwless protective grille is included. For maximum control and precise bass, I recommend a small, sealed enclosure; if you want more output in the upper bass range and have space, choose the 19-liter ported tuning.\u003c\/p\u003e","brand":"Hertz","offers":[{"title":"S4 (1x4 Ohm)","offer_id":52841087467856,"sku":"MPS-250-S4","price":319.0,"currency_code":"EUR","in_stock":true},{"title":"S2 (1x2 Ohm)","offer_id":52841087500624,"sku":"MPS-250-S2","price":319.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0933\/3004\/7312\/files\/hertz-mille-pro-mps-250-s4-s2-10-25cm-flachsubwoofer-carhifi_shop-kaufen.webp?v=1774448589","url":"https:\/\/carhifi.shop\/en\/products\/hertz-mille-pro-mps-250-s4-s2-10-zoll-flachsubwoofer","provider":"Carhifi Shop","version":"1.0","type":"link"}
