What amplifier does the A6B need?

A capable one. With 82 dB sensitivity and a 4-ohm load, the A6B suits a powerful amplifier; AsciLab recommends 50 to 500 W.

Does the A6B need a subwoofer?

Rarely. It reaches 32 Hz at −6 dB, which covers almost all music. A subwoofer mainly helps for home cinema, very large rooms or loud listening.

What it solves

Engineered to deliver accurate sound in real rooms, not just anechoic chambers.

Purifi drivers

Purifi's low-distortion aluminium woofer works with two Purifi passive radiators for deep, clean bass from a compact cabinet.

Low, steep crossover

A fourth-order crossover at 1 kHz, with the waveguide, keeps the dispersion smooth through the midrange.

Non-magnetic crossover

Non-magnetic components avoid hysteresis distortion, and every speaker is checked on a Klippel Near-Field Scanner before shipping.
