Infinity Quantum 3
Four Way Loudspeaker System (1977)
What made a company stop production of the best selling speaker in its price class? The astounding sound of Quantum 3.
We know. The company was Infinity. And the speaker we decided to phase out was our own critically praised, hugely successful Monitor IIa.
Why? Because the same Dual Drive Woofer, the same EMIT, and other electro acoustic advances in our Quantum Line Source are used in this compact Quantum 3 as well.
And the technology that goes into our Quantum Series - and the musical revelations that come out - really do stamp Obsolete across every previous speaker system, including our own.
For proof, just listen and discover that a pair of Quantum 3 speakers let you hear every instrument not only in its own voice, but in its own position front to back, as well as left to right.
Quantum 3 may well be the third best speaker in the world. For overall value, perhaps you'll rank it somewhat higher.
