MERCURY 7.4’s 44 litre twin-ported cabinet, dual 178mm (7") mid/bass drivers and refined 28mm (1.1") soft dome tweeter pack a mighty punch. To further enhance imaging and produce the widest soundstage, the drivers are positioned in a D’Appolito driver configuration. By placing the tweeter centrally between the two bass/mid drivers, the speaker’s dispersion characteristics are smoothed through the critical crossover region resulting in a highly articulate musical performance on or off the loudspeaker’s main axis. This eliminates the traditional ‘sweet spot’ to deliver peak performance across more seats in your listening room. As befits a flagship of any TANNOY loudspeaker series, the MERCURY 7.4 boasts class leading peak power handling at 300W and extremely high 93dB/Watt efficiency making it suitable for the broadest range of partnering equipment.
