Home | Speakers | Thesis | TH K3 II A ORCHESTRA

TH K3 II A ORCHESTRA Kit | 350 W Peak Power | Kit 3 way system 4 Ohm | TH 1.5 II Violino + TH 3.0 II Voce + TH 6.5 Sax

Listening to a full orchestra in a prestigious theatre is an experience that remains well impressed throughout life.

For this reason we have named the highest Thesis three-way system, Orchestra, to evoke an exceptional event that generates extraordinary pleasure.

TH K3 II A Orchestra system performance is far greater than the one achieved using individual Thesis components, reaching values of absolute excellence, going beyond the absolute.

Features

TH 1.5 II Violino

  • 34 mm CCAW single layer voice coil combining light weight, stability
    at lower frequencies and total absence of musical transients
    compression.
  • Extremely powerful custom N38 “H-grade” Neodymium magnet
    providing 1.67 T*m in the magnetic gap for superb dynamic response
    and very low distortion in the whole frequency range.
  • Exclusive air-loading system resulting in a resonance frequency below
    800 Hz, for filter set-up starting as low as 1.5 kHz – 12dB/Oct.
  • 38 mm natural silk dome optimized with extensive material
    characterization, laser vibrometer scanning and Finite Element Analysis
    methods for a smooth and extended response.
  • Frequency response up to 26 kHz optimized for off-axis installation.
  • TH 1.5 II Violino Tuning System featuring two types of electroacoustic load: bottom case or bottom disk according to targets
    of highest performance as well as flexibility of in-car integration.
  • Full solid metal construction structure with each part exclusively
    designed and produced for the Audison TH 1.5 II.
  • FEM (Finite Element Method) optimized faceplate and front spokes for
    an improved dispersion pattern.
  • eID technology providing TH 1.5 II traceability starting from the
    manufacturing stage up to the owner.

TH 3.0 II Voce

  • 30,5 mm mobile voice coil in CCAR (Copper Clad Aluminum Ribbon) wound with flat
    wire to maximize the force factor and heat dissipation.
  • Aluminium demodulation ring which linearizes the high excursion intermodulation
    distortion, canceling any sound colorations.
  • N38 “H-grade neodymium magnet included in the voice coil to obtain superior
    control of the mobile crew and superior thermal stability.
  • Motor geometry designed using finite element simulation software to optimize
    efficiency by concentrating the magnetic field in the gap.
  • Membrane made of TPX®, a transparent material that reduces frequency response
    irregularities and provides a view of the inside of the speaker.
  • Membrane geometry designed by simulation software to obtain homogeneous
    directivity.
  • Optimized cone/surround break-up with extensive simulations to linearize the
    response at medium frequencies.
  • Basket made of a single piece of die-cast aluminium with four pairs of spokes for
    maximum rigidity without slowing down the air flow.
  • Suspension and spider with very high excursion, optimized with simulations of the
    multi-physical behavior of the speaker.
  • eID technology for the traceability of TH 3.0 II Item from production to purchase.

TH 6.5 II Sax

  • 50 mm mobile voice coil in CCAR (Copper Clad Aluminum Ribbon)
    wound with flat wire to maximize the force factor and heat dissipation.
  • Low inductance of the mobile voice coil to optimize the emission in
    medium-high band (2-3 kHz).
  • N48 “H-grade” neodymium magnet with superb thermal stability to
    guarantee an optimal dynamic reserve in every situation.
  • Magnetic group geometry designed using finite element simulation
    software to maximize efficiency by concentrating the magnetic field in
    the gap.
  • Membrane made of TPX®, a transparent material that reduces the
    frequency response irregularities in the mid-high band, leaving the
    speaker interior in full view.
  • Membrane geometry designed using simulation software, to obtain a
    smooth emission over all the listening angles.
  • Basket made of a single piece of die-cast aluminium featuring four
    pairs of spokes to optimize heat transfer, nullify turbulent airflows and
    ensure maximum structural rigidity.
  • Hi-excursion suspension and spider, optimized with simulations of the loudspeaker multi-physical behavior.
  • eID technology providing TH 6.5 II traceability starting from the manufacturing stage up to the owner.
