Extra Info:

Selling this system with great regret, but it's gathering dust. Having designed high-end loudspeakers professionally for many years, I created this constant-directivity dipole system from the ground up from the very best components available.


  • The RAAL dipole tweeters include amorphous core, a 20uF for protection, and the addition of felt to improve the directivity match to the mid-range.
  • The tweeters and 4" midrange are suspended from a frame, avoiding baffle resonances.
  • The 12" mid-bass' are mounted on a small baffle (18mm ply) to increase low-frequency extension.
  • The 21" woofers are mounted in H-frame cabinets (18mm ply) to increase low-frequency extension.
  • The MiniDSP includes all crossover and equalisation settings. However, no amplifiers are included, so 8-channels of amplification and some gain adjustment will be required. I drove the tweeters/mids with 180W/ch and mid-bass'/woofers with 350W/ch pro-audio power amps (already sold).


Sale price for entire system including drivers, frames, baffles, cabinets, DSP w/ original settings: $3,200

Separate pricing

Tweeters: $1,300 for pair

Mids: $400 for pair

Mid-bass': $600 for pair incl. baffle

Woofers: $800 for pair incl. baffle

MiniDSP: $400

Hi John,


Yes they are still available; as mentioned in the above post, one of the ribbons has some superficial creasing on it. Are you in Sydney? PM me for more details if interested.

      Cartridge --The Clearaudio Concerto 
      Clearaudio has significantly improved our fully symmetrical MC design, first patented in 1980.

      We redesigned the generator in a revolutionary way by positioning and doubling the magnets (to 8 pcs.) so the coils are operating in a much stronger magnetic field. Furthermore we have chosen the strongest magnetic material available: super neodymium. Through these achievements, the efficiency has been raised by 30%, which results in an output of up to 0.9 mV at 5cm/sec. All models now utilize the improved V2 generator.

      The new Micro-HD Diamond tip provides a hybrid parabolic geometry with a stylus radii of 0.008mm x 0.040mm. The total mass (0.00016g) is a fifth of the previous diamond stylus.

      Cartridge body resonances, while tracking in the groove, are minimized through the twelve finger design of the mounting plate, each finger with a different radius. This is the result of our constant research and development.

      The cartridge bodies of our 5 models: Goldfinger, Titanium, da Vinci, Stradivari and Concerto are made out of the following: gold, titanium, ceramic coated aluminum, Ebony and Satinee wood. The generator construction of the new V2 moving coil cartridge generation is absolutely symmetrical: mechanically, magnetically and electrically, our unique design. All Clearaudio moving coils use our proven 24 ct. pure gold coils.

      All the design aspects of Goldfinger, Titanium and Stradivari are found in the Concerto V2: the entry-level into our New-Generation-Super class of moving coil cartridges.

      Both the satiné wood from which the body is made and its resonance-optimised shape contribute towards the excellent performance of the Concerto V2, the baby of the Clearaudio flagship range
      Clearaudio Concerto V2 MC Cartridge
      With a dynamic range of up to 70 decibels and a total weight of only seven grams, the mc concerto v2 qualifies itself for the top league of moving coil cartridges.
      Within this satin wood body the technology is outstanding, housing 24-carat gold coils and a patented eight-magnet array unique to our V2 range. Further champion-level ingredients are the boron cantilever and Micro HD stylus. A recipe to win the trophy of sound championship.
      Total weight: approx. 7.0 gram Output voltage: 0.6 mv at 5 cm/s Material/color: satinè wood with metal platter STYLUS SHAPE Micro HD COMPLIANCE 15/15 μ/mN REC. TRACKING FORCE 2.8 g REC. LOAD RESISTANCE 300 Ohm OUTPUT VOLTAGE 0.6 mV at 5 cm/s CARTRIDGE IMPEDANCE 50 Ohm CARTRIDGE BODY Satinè wood with metal platter TOTAL WEIGHT Approx. 7.0 gram
