The DoogeHiFi NAAD Ti51-C is a custom-engineered, 2-way passive centre channel loudspeaker developed with a clear objective: to deliver natural, detailed and intelligible dialogue while maintaining the tonal balance and musicality expected from a Hi-Fi audio system.
Featuring two 5.25-inch woofers and a dedicated tweeter, the NAAD Ti51-C combines a carefully designed bass-reflex enclosure with a custom-engineered passive crossover. The crossover incorporates tweeter level matching and woofer impedance linearisation to help achieve a balanced, cohesive presentation across the frequency range.
Particular attention has been given to vocal reproduction. From subtle dialogue and soft-spoken conversations to powerful cinematic performances, the design aims to preserve vocal clarity, tonal naturalness and the details that bring characters and stories to life, without making voices sound unnaturally bright or fatiguing.
The NAAD Ti51-C is designed primarily for the centre channel in a home theatre system, where clear dialogue and consistent vocal reproduction are essential. Its Hi-Fi-oriented design philosophy also reflects the importance of natural timbre, making it a carefully developed part of a cohesive, high-quality multichannel audio experience.
Housed in a rear slot-ported bass-reflex cabinet measuring 620 × 190 × 260 mm, the NAAD Ti51-C combines a substantial dual-woofer configuration with a dedicated centre-channel form factor.
DoogeHiFi NAAD Ti51-C, because every story deserves a voice that sounds natural, clear and true.

The titanium dome tweeter is supplied with a protective grille. However, as the speaker is relatively heavy, please take extra care while positioning or moving it. When cleaning the speaker with a brush or dry cloth, handle it gently and avoid applying pressure to the tweeter grille, tweeter dome, woofer cones, or woofer dust caps.
Please note that physical damage to the tweeter dome, woofer cones, or woofer dust caps resulting from improper handling, placement, or cleaning is not covered under warranty.
