DC Audio Level 4 15" Subwoofer

The DC Audio Level 4 15" Subwoofer is a high‑power, SQ‑focused driver that combines a large triple‑stacked motor with advanced heat management, available in 10, 12, 15 and 18 inch sizes for demanding car audio builds. It represents a step forward in both sound quality and thermal performance over the previous m3 model.

• Power Handling: 1500W RMS / 3000W Peak. In real-world use this provides substantial headroom for dynamic musical passages and high‑use bass without immediate clipping, given proper enclosure and amp pairing.
• Voice Coil Options: Dual 1, Dual 2, and Dual 4‑ohm versions. You can tailor impedance to your amplifier or create multi‑coil wiring configurations for different wiring schemes and load stability.
• Motor and X‑Max: Large triple‑stack motor with chrome top plate and LV4 logo; 23.5 mm of X‑Max. This combination supports deep excursion with controlled linearity for tight, powerful bass at high output.
• Inductance Reduction and Heat Path: 2.5 mm aluminum shorting ring. Reduces inductance and acts as an internal heatsink, helping lower power compression and maintaining performance during long, demanding sessions.
• Thermal and Airflow Design: The ring pulls heat from the windings toward coil venting, with air moved across both the coil windings and aluminum ring for effective cooling during operation.
• Construction and Materials: Extremely rigid non‑pressed paper cone; multilayered polymer foam stitched surround; polypropylene dust cover with DC logo. These elements support linear excursion and durable long‑term performance.
• Frame, Spider, and Lead Wire: Cast aluminum black frame (no invert mount); triple 8" OD semi‑cup progressive roll spider; extra heavy‑duty interweaved tinsel lead wire sewn to the spider. This combination provides robust mechanical stability and reliable electrical connections under vibration.
• Voice Coil and Magnet Cover: 3" high‑temp aluminum voice coil on a black anodized former; 8‑layer flat‑wound rubber magnet cover with DC and LV4 logos. The coil and magnet assembly are designed for sustained high‑power operation and protection of the magnetic structure.
• Terminals and Sealing: Chrome spring‑loaded push terminals; rubber mounting gasket. These features aid secure connections and chassis sealing in automotive environments.
• Impedance and Size Range: Ohm options listed as d1/d2/d4; size range covered is 10", 12", 15", 18" with identical 1500W RMS rating across sizes.
• Displacement: 10".16 ft; 12".18 ft; 15".21 ft; 18".26 ft. Higher displacement contributes stronger low‑end in suitably built enclosures.
• Box Suggestions: Sealed box recommendations: 10" 0.75 ft, 12" 1.0 ft, 15" 2.0 ft, 18" 3.5 ft. Ported box recommendations: 10" 1.0 ft, 12" 1.5 ft, 15" 3.0 ft, 18" 5.5 ft. These sizes help guide enclosure design for intended performance.

Benefits: In practical builds, the Level 4 15" delivers deep, controlled bass with ample headroom thanks to its 1500W RMS rating and 23.5 mm xmax. The 2.5 mm aluminum shorting ring reduces inductance and improves cooling, mitigating power compression during long, dynamic passages. The rigid cone, stitched surround, and CNC‑machined motor assembly preserve linear excursion and low distortion across sizes, while the cast aluminum frame and rugged lead wire assembly ensure durability in a vehicle environment. Compatible with multiple impedance options, it suits both sealed and ported enclosures guided by size‑specific box recommendations, making it a versatile choice for serious SQ and high‑level SPL setups.
