TCMT 6.5ft King Trunk Rear Speaker for Harley Touring 2014-2023

Our review of the TCMT 6.5' King Trunk Rear Speaker finds it best suited for Harley owners who want a direct, budget-friendly upgrade for the trunk-mounted audio in Touring models. The single biggest reason to buy is its focused compatibility with 2014-2023 FLHT, FLHX, FLHXS, FLTRX and FLTRXS bikes equipped with King Trunk luggage and a Boom! Box audio system, delivering clear midrange and a high sensitivity that translates to noticeable volume without extra power. Installation is straightforward for anyone comfortable with trunk disassembly, though buyers should note mounting hardware and harness are not included.

Key Features

• Direct fit: Designed specifically for King Trunk-equipped 2014-2023 Harley Touring models, so replacement is plug-and-play when the correct harness and mounting are present.
• Balanced output: With a 30W output and 92dB sensitivity, the speaker delivers good loudness from standard Boom! Box systems without demanding extra amplifier power.
• Wide frequency range: A 45Hz to 22kHz range gives reasonably full response for trunk-mounted use, providing audible low end and clear highs for road use.
• Durable components: PP cone material and a 14.5 oz magnet indicate a solid, road-worthy build that will stand up to vibration and exposure common on motorcycles.
• Silk dome treble: A 20mm silk dome tweeter helps maintain smooth high-frequency response and reduces glare on vocals and instruments at cruising volumes.

Who It's For

The TCMT King Trunk Rear Speaker is ideal for Harley-Davidson Touring owners who already run a Boom! Box system and have the King Trunk luggage configuration. Riders who want an economical, OEM-style replacement with good sensitivity and clear mids will appreciate the balance of sound and value. It is also a suitable option for those who prefer to keep installation simple and stay with factory-style speaker pods.

Not every rider should buy this: if you need included mounting hardware or a full plug-and-play harness, look elsewhere or plan to source those parts separately. Audiophiles seeking large-woofer bass extension or professional-grade components will want higher-powered, dedicated aftermarket systems instead of this 30W-per-speaker design.

Pros & Cons

Cons

• Some customers report isolated fitment issues with speaker covers or screens coming loose under vibration.
