Infinity Quantum 5


It is very difficult to believe, before hearing, and even after, that a medium size and reasonable priced loudspeaker can contain the most advanced driver for low and high frequencies, plus a series of good quality medium domes.

We thought it would be impossible to lower the price of our Quantum series. We proudly announce we were wrong.

Own a pair of Quantum 5 loudspeakers and you are at the concert!
