Performance Optimized Sealed 10" Enclosure | Sony ES

Performance Optimized | Sony Mobile ES Single 10" Sealed Enclosure | Driver-Specific for the XS-W104ES 1.0 ft³ Net Driver-Specific Threaded Inserts 20" × 14" × 9.5" Langboard Elite MDF Built in Tennessee The Sony XS-W104ES Deserves a Box Built for It Sony's Mobile ES Series represents the pinnacle of their car audio engineering. The XS-W104ES is built around a mica flake / aramid fiber / pulp cone with a honeycomb core, separated-notch rubber surround, and a 450-watt RMS power rating that demands a properly sized cabinet to deliver on its potential. Drop it in a generic box and you'll get good bass. Drop it in a cabinet engineered around its intended sealed alignment and you'll hear what the Mobile ES Series was designed to do. The Performance Optimized Sealed 10 for Sony ES is that cabinet. Internal volume, baffle thickness, and mounting hardware are all chosen to extract the XS-W104ES's full mechanical and acoustic potential — not approximated, not averaged across a class of 10s, not adapted from a universal box. This enclosure is engineered specifically around the Sony XS-W104ES. The 1.0 cu ft net volume and direct-fit cutout are tuned to the Mobile ES Series 10 — not a generic 10" platform. Why Performance Optimized Sits Where It Does The Performance Optimized line is the bridge between our standard Performance Series and our top-tier Professional Series. Same Performance-tier construction quality — Langboard Elite MDF, V-groove and dado joinery, ShopSabre CNC routing — but the geometry of every panel is cut around one specific driver instead of a class of drivers. vs Performance Series Standard Performance Series boxes (P6 through P15) are built for universal driver fitment within a size class. Great if you want flexibility across multiple driver options. Performance Optimized takes the same construction and locks the airspace and hardware to one specific driver. vs Professional Series Professional Series uses extensive multi-layer baffles, triple-stacked construction, and a 2-year warranty for the most demanding builds. Performance Optimized delivers driver-specific engineering at a more accessible price point with a 1-year warranty. Engineered Around the XS-W104ES The Sony Mobile ES Series 10" performs best in a sealed cabinet that gives the cone the right air spring without overdamping the response. 1.0 cu ft net is where the XS-W104ES settles into its intended SQ-oriented sealed alignment — tight, articulate transients on kick drums and bass guitar, controlled low-end extension, and the tonal accuracy Sony engineered the Mobile ES Series cone composition to deliver. Volume Selection 1.0 cu ft net is the airspace that lets the Sony cone work cleanly without fighting the cabinet. Smaller volumes overdamp the response and dry out the bottom end. Larger volumes loosen Qtc and compromise the Sony's signature controlled presentation. 1.0 cu ft is the SQ-oriented sweet spot for the Mobile ES Series 10. Mounting Geometry The baffle is cut to the XS-W104ES's exact direct-fit specification. The 5.382" mounting depth on the Sony leaves comfortable internal clearance behind the magnet structure inside the 9.5" deep cabinet. No interference, no airspace robbed by a deep motor. Performance Series Construction, Driver-Specific Tuning Langboard Elite MDF Premium 3/4" MDF panels milled to documented spec — denser and more dimensionally stable than commodity MDF. Less panel resonance, tighter joints, and a longer service life under daily use at real power levels. V-Groove and Dado Joinery CNC-cut V-grooves at every panel intersection let the cabinet fold into shape with maximum glue surface. Dado joints lock the baffle and rear panel into the side walls — no fasteners visible from outside. 8/32 Threaded Inserts Threaded inserts pressed into the baffle backside accept stainless steel mounting screws. No stripped pilot holes, no MDF damage from drywall screws, no surprises when the next driver upgrade rolls around. Pre-Wired Terminal Cup Proline X ABS/carbon fiber composite terminal cup, pre-wired with 12-gauge OFC inside the cabinet, with stainless steel hardware accepting both spade and banana terminations on the input side. Every panel is cut on ShopSabre CNC routers in our Tullahoma, TN facility. Tolerances that manual fabrication can't hold — joints close cleanly, baffle concentricity stays accurate, and internal volume is consistent unit to unit. Customize Your Build Carpet Finish Dark Gray Trunkliner is the standard durable wrap, matched to most factory trunk and cargo-area carpet tones. Plush Black (+$10) is a deeper, more luxurious nap that pairs well with blacked-out interiors and show builds. Acrylic Insert Color Choose Black, Blue, Red, or White for the baffle insert to match your build. Or skip the insert entirely (-$40) for a clean, understated look. The insert is purely cosmetic — performance is identical across colors. Box-Only or Loaded Add a Sony XS-W104ES driver directly to your order and we'll ship the complete loaded system, ready to wire to your amplifier. Already own your XS-W104ES? Order the enclosure box-only and drop in the driver you have. Wiring the XS-W104ES to Your Amplifier The Sony XS-W104ES is a single 4-ohm voice coil driver — simpler wiring than a dual-coil design, and ideally suited for monoblock subwoofer amplifiers stable at 2 or 4 ohms. The pre-wired terminal cup accepts the XS-W104ES's gold-plated spring terminals via 12-gauge OFC, with stainless hardware on the input side that accepts both spade and banana terminations. The XS-W104ES is rated for 450 watts RMS. Aim for a clean, well-regulated amplifier delivering 350 to 450 watts at 4 ohms — Sony designed this driver for refined power, not headline numbers. Mobile ES Series amplifiers from Sony's lineup are engineered to pair specifically with this driver, but any quality monoblock with honest 4-ohm output will work. Built in Tennessee, Backed by Audio Intensity Every Performance Optimized enclosure is CNC-cut, assembled, and finished in our Tullahoma, TN facility. Components are pulled from inventory after your order is placed, then bonded and wrapped — a 2 to 5 business day assembly window before the box ships. No pre-built inventory sitting in warehouses, warping in storage. Each unit is built to order. Backed by a 1-year limited warranty against structural failure and hardware defects.
