Product Information
Overview
The Alpine RSW10D4 Shallow 10-inch Subwoofer revolutionizes car audio with its ultra-compact design and exceptional sound output. Despite its space-saving profile, this subwoofer delivers the same powerful performance you'd expect from much larger units, making it ideal for vehicles with limited installation space. Its innovative design and advanced technology provide an impressive 600 watts RMS of bass-pounding power that transforms your listening experience.

Engineered for Excellence
The Alpine Shallow 10-inch Subwoofer features a remarkable oversized 4-inch voice coil powered by a neodymium magnet, producing a 20mm cone excursion that rivals full-size subwoofers. This powerful combination enables the RSW10D4 to move substantial air volume, creating deep, responsive bass despite its shallow mounting depth. The subwoofer's cutting-edge Gen2 DD-Linear Magnetic Circuit technology ensures precise bass control with minimal distortion, delivering clean, accurate low frequencies that enhance every music genre.
Space-Saving Solution
With a mounting depth of only 3.25 inches (82.55mm), the Alpine Shallow 10-inch Subwoofer fits in locations where traditional subwoofers won't, including under seats, in shallow enclosures, or in vehicles with limited depth clearance. This versatility makes it perfect for compact cars, trucks with limited space behind seats, or any installation where depth constraints present challenges. Despite its slim profile, you'll experience the same powerful, room-filling bass performance that Alpine's R-Series is renowned for.
Premium Construction
Built with uncompromising quality, the RSW10D4 features a die-cast aluminum frame that provides rigid, sturdy support while reducing unwanted resonance. The lightweight yet durable aluminum dust cap enables quick sound transitions with minimal distortion, projecting bass efficiently for hard-hitting yet smooth performance. Every component has been engineered for reliability and longevity, ensuring this subwoofer delivers exceptional performance for years to come.

EBP Calculator
Choosing the right enclosure for your subwoofer isn’t guesswork — it’s science. The Efficiency Bandwidth Product (EBP) is a simple calculation that uses a driver’s Fs (resonance frequency) and Qes (electrical Q) to determine whether it performs best in sealed, ported, or both types of boxes.
- EBP under 50 → Works best in sealed enclosures for tighter, more controlled bass.
- EBP over 100 → Better suited for ported designs where efficiency and output are the priority.
- EBP between 50–100 → Flexible enough to perform well in either design, depending on system goals.
Use our interactive calculator below to compare subwoofers, see where each model falls, and make an informed decision on the best enclosure type for your setup.
Efficiency Bandwidth Product (EBP)
Fs (Hz): 31
Qes: 1.66
Lower EBP → Sealed. Higher EBP → Ported.
Xmax (mm): 20mm
Mounting Depth (inches): 3.25
