Infinity Quantum 2


Your ears may not know the difference between this superb speaker and its progenitor, the Quantum Line Source - until you hear the price.

In the Quantum Line Source, the range of the Infinity Watkins Dual Drive Woofer extends down
to 18 Hz. Here in the closest competitor, the Quantum 2, it reaches 24 Hz - but you get an extra 2dB of efficiency.

Our Quantum Line Source stacks its Electromagnetic Induction Tweeters (EMITs) eight high. The more compact Quantum 2 uses the same tweeters, but not quite so lavishly.

Same high definition 3.8 centimetre dome midrange driver; same transmission line midbass coupler; same scrupulous attention to phasing and crossover technology.

Hear Quantum 2. Its resemblance to the Infinity Quantum Line Source is striking. Except around
the price tag.
