Yamaha NS-P20 Review - Features Review


For just over £100 don’t expect advanced, complex speaker tech. The NS-B20s use an acoustic suspension design with a single 7cm full range cone handling frequencies up to 25kHz. The centre features the same spec inside its longer enclosure.

The subwoofer, however, does boast some clever tech, namely Advanced Active Servo Technology, which for some reason is abbreviated to Advanced YST. As the above diagram shows, the speaker and amplifier work together to cancel out impedance as the speaker moves, improving the rigidity of the 160mm cone and preventing resonant waves from leaking out of the speaker cone. All of the waves are pushed through the linear port in the side of the cabinet, theoretically resulting in deep, powerful bass.

The subwoofer musters 50W power output, which doesn’t sound much but the Advanced YST is designed to make it sound bigger. On the back of the unit is a volume dial, single RCA input and power button, but no means of controlling crossover or phase.
