Trinity M Series 6.5" Subwoofer 400 Watts RMS

The Trinity M Series 6.5'' Subwoofer 400 Watts RMS is a compact bass driver built for high output with tight, low-distortion bass in a small footprint. It uses a double-stacked ferrite motor with FEA optimization and a heat-dissipation airflow system to maintain performance under demanding use.

• RMS Power handling: 400W RMS continuous with 800W burst; provides headroom for dynamic bass without clipping at high levels.
• Voice coil configurations: Two options — M65 D2 with two 1.9 Ω coils or M65 D4 with two 3.2 Ω coils — for flexible amplifier and wiring choices.
• Double-stacked ferrite motor: Two-layer magnet design optimized via Finite Element Analysis for strong magnetic flux and precise cone control.
• Heat management: Optimized airflow across the motor and basket to dissipate heat during extended sessions, preserving performance.
• Surround and cone: Triple-layer foam high-excursion surround with a rigid composite paper cone for durable, responsive bass.
• Spider and coil build: 5.4" layered progressive Nomex spider pack and a 2" BASV high-temperature dual voice coil support reliable operation at high power.
• Enclosure compatibility: Suitable for ported or bandpass enclosures, enabling deep bass in diverse install types.
• Physical fit: Outer Diameter 7.09 in; Cutout Diameter 5.9 in; Mounting Depth 4.17 in for precise enclosure planning.
• Materials and construction: Ferrite Grade Y35 magnet, 8ga terminal wire, and robust coil construction designed for longevity.

In a real car build, this driver delivers deep, controlled bass from a compact footprint, performing in both ported and bandpass configurations. The dual-VC design lets you tailor wiring for your amplifier, while the heat-management features keep power handling consistent during long listening sessions. The rigid cone, durable surround, and Nomex spider pack support precise, low-distortion bass across the range, making it suited for daily drivers and competition-grade setups alike.
