Calypso HD

Specifications: Concentrated state of the art

Model Comparison Chart >


Performance details

Application(s). Time-coherent 3-way floorstanding speaker for use in all but the largest of rooms.

Room size. Medium to large, 300-1,000sf.

User adjustability (Soundfield Convergence™). Midrange and tweeter positions adjust front-to-rear independently.

Power (amplifier’s 8 ohm rating). 7 to 170 Watts.

Response. In-room, typically +/- 2dB from 45Hz to 20kHz; -3dB frequencies below 40Hz and above 22kHz.

Distortion. <0.5% harmonic 100Hz-12kHz, <1% intermodulation, both at 100dB at 1m. (I.M.D. is for any two frequencies separated by a 10:1 ratio.)

Phase shift. +/- 3 degrees acoustically, from 220Hz to 8kHz. Does not vary with loudness.

Rise time. <10 microseconds, positive or negative input. Does not vary with loudness.

Polarity. Positive, over full bandwidth.

Dispersion. Omni at 40Hz, smoothly decreasing to cardioid at 10kHz.

Impedance. 4.75 Ohms, +/- 0.75 Ohms 150Hz to 20kHz. Does not vary with loudness.

Sensitivity. 88dB for 2.83V at 1m, at sea level. Dynamically linear within 0.5dB to 100dB.

Max SPL. 105dB peak at 3m from a stereo pair, first-arrival (without room gain).

Pair matching. Amplitude +/- 0.25dB; impedance +/- 0.15 Ohms, 160Hz-8kHz; crossover parts +/- .15%.


Physical details

Cabinet finish and choices. Clad in black Texture-Kote™ for the look of pin-grained leather. Solid wood side panels in cherry, walnut, figured maple or African ribbon mahogany are standard. Other woods such as Bubinga or Cocobolo can be quoted.

Speaker Conditioning. Upon request, we will gladly condition the speakers' drivers before shipment at no additional charge.

Bi-Wire. Calypso HD may be bi-wired for US$900. If you do not already own two sets of high-quality speaker wires, we prefer that you do not order this option and instead, invest in one set of superior wires.

Upgrades. Not available for Calypso to Calypso HD status.

Grilles. Speakers have been designed for grilles to be left in place.

Accessories supllied. EarStick; nut driver; T-handle Allen wrench; adjustable cone feet with hardwood floor protectors and Ownership Guide.

Size. 51"H; 13.5" Square at base.

Weight. 100lbs. (45kg) each; may vary depending upon side panels chosen.

Technical specifications

Woofer

Woofer diameter. 8" (21cm).

Woofer construction. Low-mass Nomex fiber rigid cone. Very low resonant frequency from highly-compliant ultra-linear suspension of synthetic rubber and fully-vented flat spider; high-power, 4-layer 1.25" (32mm) voice coil. Alloy chassis; 22.5oz. (640g) magnet; 0.35" (9mm) p-p linear excursion; 30.6g moving mass. Shorting rings around voice coil for low distortion.

Woofer cabinet. Woofer mounted in Q-Stone™ chamber atop slender wood column, twisted 45 degrees to reduce reflections. Internal Golden-Ratio Baffle™, 4th-order Butterworth ported with nearly zero box loss.

Woofer / Bass port. 3" (7.5cm) aerodynamic port on rear side tuned to 42Hz. An angled location prevents the Calypso HD’s port from resonating with the space to the wall behind. Working with the internal Golden-Ratio Baffle™, the port transmits pressures most efficiently. No tones other than the lowest bass will emerge. Mirror-imaging allows proper operation in all rooms.

Midrange

Midrange diameter. 4" (10cm).

Midrange construction. Low-mass rigid cone of Kevlar skins laminated over Nomex honeycomb core. 6.2g moving mass. Very low resonant frequency from high-compliance suspension. Coated foam surround and large spider. 1" (25mm) hex-wound copper voice coil on Kapton former, vented at rear. Carbon fiber reinforced ABS non-magnetic chassis; 20oz. (567g) magnet. 0.25" (6mm) p-p linear excursion. Response -3dB at 350Hz and 3,150Hz.

Midrange enclosure. Resistively vented in alliptic, non-diffractive Q-Stone™ enclosure containing damped acoustic line. The resistive vent suppresses the natural low-frequency resonance. A second-stage muffler has been added over the rear of this vent.

Tweeter

Tweeter diameter. 1.1" (28mm).

Tweeter construction. Lightweight linen dome, hand-coated with polymer. High-compliance, inverse-roll contiguous suspension. Hex-wound copper-clad aluminum voice coil wire, Ferrofluid cooled, high-strength aluminum alloy former, vented into large, damped rear chamber. 0.46g moving mass. Double neodymium magnets, fully shielded.

Tweeter enclosure. In alliptic, non-defractive, Q-Stone™ enclosure with integrated tweeter chassis damping.

CopperMatrix

Wiring. Woofer, Midrange, Tweeter: Exclusive High Definition CopperMatrix™ wire by Marigo Labs: 18-gauge, 500+ strand Litz wires of six-nines purity, single crystal, oxygen-free copper with proprietary winding geometry; double cryogenically-treated, organic dielectric insulation; proprietary internal vibration damping system. Pure metals love to ring. They do so sideways and also along their lengths. Because of their design, these CopperMatrix™ wires do not and can not ring.

Binding-posts

Crossover. Balanced-Phase™ first-order circuit.

Zobel circuit's capacitor. Woofer, Midrange, Tweeter: Ultra-premium quality.

Crossover principal capacitor. Woofer: N/A. Midrange, Tweeter: Ultra-premium quality.

Crossover bypass capacitor. Woofer: N/A. Midrange, Tweeter: Ultra-premium quality.

Binding posts. Made by Vampire Wire of pure oxygen-free copper, directly gold plated. Mounted on the back.
