Stereo Integrity TM65 MKIV 6.5" Midbass Speaker (Pair) | 150W RMS

Stereo Integrity TM65 MKIV 6.5" Midbass Speaker (Pair) | 150W RMS – Aggressive Midbass Meets Smooth Midrange

Experience legendary pant-leg-slapping midbass with the Stereo Integrity TM65 MKIV 6.5" Midbass Speakers, delivering 150W RMS of low-distortion power and smooth midrange detail. Designed in North Carolina using Finite Element Analysis (FEA), the TM65 MKIV combines aggressive output, thermal efficiency, and compact installation depth for serious car audio enthusiasts.

Engineered to maintain the signature TM65 performance, the MKIV version enhances clarity with a pure aluminum cone body, 50mm CZA former voice coil, and solid copper windings for both strength and heat dissipation. Its twin shorting rings (copper pole sleeve + magnet ID ring) lower and linearize inductance, achieving an Xmax:Le ratio typically found in far higher-priced drivers.

With 7mm Xmax (one-way @ 70% BL), the TM65 MKIV delivers deep, punchy midbass while maintaining fluid midrange up to 3,500 Hz off-axis and on-axis extension up to 8,000 Hz. Designed for vehicle door installations (infinite baffle alignment), the 0.65 Qts ensures excellent low-frequency extension and natural output capability without sacrificing mounting space.

Pair the TM65 MKIV with Stereo Integrity M3 Carbon wideband drivers or M25 MKII tweeters for a world-class front stage that balances impact and detail.
