Info Duet10
    Background:
    After many years of testing various drivers and
    experimenting with different crossover topologies, we have
    found a combination of drivers and crossover synergy that
    brings a level of performance never seen before in high end
    audio at our price.

    Design Goals:
  • Develop a 3-way speaker that brings reference levels of
    transparency.  
  • Utilize state-of-the-art drivers yet still represent a solid
    value
  • Offer several driver configurations to fit the customer's
    budget.
  • Maintain the philosophy that an increase in price should
    represent an increase in performance.

    Performance:
    Some of the highlights of this speaker include a crossover
    that hits Linkwtize Riley 2nd order slopes, drivers that have
    absolutely the lowest harmonic distortion profiles, and a
    very linear frequency response that is true to the source.  
    The phase alignment is virtually flawless, and the summing
    of the drivers results in a flat frequency response on and off
    axis.  The design can be built either sealed or ported. If
    sealed, the bass will extend to an F3 of 42hz.  One could
    then augment the Duet10 with a subwoofer.  However,   in a
    ported enclosure, it will allow the bass to extend below 30hz
    in room.   This should satisfy most listeners.  The sound is
    detailed, smooth and extended.  Honestly, it doesn't get
    much better than this.  

    The Duet10 uses extremely high end drivers but reflects a
    solid value at the same time.  Several driver options are
    available. The tweeter is the outstanding Scan Speak 6600
    or Illuminator 6620.  The midrange is the Scan Speak
    15W4531G with a non-coated paper cone or the extremely
    high end Accuton C173-T6 90.  The woofer can either be a
    Seas L26 aluminum cone woofer, Excel W26 or Scan Speak
    26W aluminum cone woofer.  

    Currently, the following driver combinations are available.

    Duet10SS
    Scan Speak Air Circ tweeter or Illuminator 6620, Scan
    Speak 15W4531G, and Seas L26 or Seas W26 woofer.

    Duet10A
    Scan Speak Air Circ 6600 or Illuminator 6620, Accuton
    C173-90, and Scan Speak 26W aluminum 8 or 4 ohm
    (pictured).

    We use Clarity Caps (ESA on the tweeter and PX elsewhere),
    poly caps for values above 80uf, high quality resistors, low
    DCR air core coils, and absolutely no electrolytic
    components.  Only the highest quality parts are utilized to
    extract every once of detail from the signal.

    For the best sound place the speakers a couple feet away
    from walls, but feel free to experiment.  


    Frequency Response:  30hz-20k +/- 2.5db Ported
    Sensitivity:  82db-85db (depends on woofer choice)
    Impedance: 4 or8 ohm nominal (depends on woofer choice)
