Four times powered

Quadra‘s frequency response curve is oriented to magnitude. The engineering of this model gives incredible dynamics on all the spectrum with particular force on bass frequencies. Super highs are stunning as well, exceeding the Zero dB over the 10k mark. A model of sound for demanding and loud live performers needing active and passive insulation and detailed monitoring.
Quadra can raise the dead!

Going for a Quadra?

  • A model that screams in your ears!
  • For live performance and for loud music lovers.

The sound design of Quadra was created with an idea similar to the one behind Tria Live!
We are oriented towards musicians who love listening to everything with the right magnitude and no useless overwhelming frequencies. This is the model that reproduces the best bass drum, the best bass groove and the best acute guitar note ever on stage and that can withstand any kind of music: from jazz to pop to metal.
High magnitude, keeping all the details.

With  Quadra…you will never say “I cannot hear” anymore!

Music becomes live!

Quadra is serious about giving the live performance the necessary feedback and the necessary detail. There’s nothing that Quadra cannot play. It’s an intermediate and really aggressive model priced for the quality and the overall results it can give!

Incredible cables

The standard cable provided with Quadra is an extremely qualitative, made in Usa, 2 gold plated pin cable with free upgrade to the Linum® G2 BaX™Linum® G2 Super BaX™ cable is available as option on this model. Linum™ cables come with a free upgrade in the socket with the adoption of the incredible T2™ system.

Porcelain feeling

Porcelain is definitely worth a try: you will be amazed by the extreme comfort of its smoothness conferred by the glaze, its total naturalness, its thermal adaptability and the absence of any allergene.
If you would never wear a plastic tooth, then you deserve porcelain in-ears!
