A Few Notes on the  PandaTM  Model 10 Loudspeaker.

            This loudspeaker has evolved out of well over twenty five years of my design work with loudspeakers and audio componentry. It carries the pinnacle of all my ideas and innovations that I have developed in audio and also the painful removal of many cherished mindsets. The Enclosure is a true point source alignment ( meaning that the two woofers are located at the quarter volume points of the internal volume of their enclosure ) One tweeter surrounded with two woofers.  Consisting of two 9" woofers and a single 1" tweeter  and with a forst order Butterworth for the Woofer with zoebel network and a full 3rd order Butterworth  with L pad for the Tweeter, the simplicity of  the speakers belies their exceptional performance.

            The PandaTM  Model 10 Loudspeaker  enclosure is 1600mm high, 400mm wide and 702mm deep and 50mm ( min) thick .  In imperial measurements that's: 63inches high x 16 inches wide and 28inches deep and 2 inches ( minimum ) thick.  The enclosure is locked by both its internal bracing and numerous metal fasteners and high strength glue. The front panel is of a Monolithic construction ( 70mm+ thick; nearly 3 inches ); It sits proud of the other panels and is seamless in all directions minimising diffraction effects . Each speaker box is centred onto its own dedicated high density  wooden plinth which is 600mm wide and 900mm deep and 100mm high ( 24 inches wide x 36 inches deep and 4 inches high ). The internal volume is over 258 litres ( or just over 9 cubic ft ) and each enclosure weighs just over 240Kg ( 500lbs+ ).

                Internal wiring is  with custom made  Silver   ( >4N ) rectangular section ribbon   for the woofers  and  Fine  Silver ribbon for the tweeters. The Ribbon is heatshrunk with Kynar Heatshrink. The use of  solder is restricted to attaching the  single wire to the tweeter; no solder is used in the Woofer // Mid circuit.
All crossover connections are terminated in specially designed and manufactured ( by Bocchino Audio )  junction assemblies known as WireGrubsTM( All manufactured  from Pure Copper, then Silver plated ).
All transducers are secured onto the Monolith with stainless steel bolts secured into  custom made fasteners.
The inductors are wound from pure copper foil and the capacitors are metal foil   high voltage types along with some German Silver-Mica capacitors .
The Woofers have a  specially designed Transducer Binding post known as WireTailsTM fitted in place of its standard binding post. The woofers are factory modified to accommodate the dedicated designed WireTailTM.

                Internal Damping is of a unique ‘air-gap’ buffer design with the majority of the air in the box acting in synergy with the working transducers. Rear Binding posts are BMNP-M13MkV  Monopoles® . These, too, are fabricated from Pure Copper; Silver plated ( No Nickel!  Hence no Hall-effect ).

                Originally designing loudspeakers for others ( 1983 - 1988 ) I decided to investigate exactly what makes a loudspeaker transducer feel comfortable within  its working environment. A few very narrow parameters came out of all this  research and seeking loudspeaker transducers with these parameters proved immensely difficult. There are only two such woofer transducers that come close to these parameters. Both are exceptional in their performance but one is better than the other. Only the best went into the Panda’sTM.
Nominally QTS=0.5 and VAS>135 among some of the parameters.
 

THE SOUND.

What sets these speakers apart from almost any other loudspeaker is their ability to effortlessly handle a very broad dynamic range while delivering a very involving musical experience. All the metaphors of timbral accuracy and image precision are all exceptional and go without saying.
Emotional involvement with the music is very real. A lot of design has gone into ensuring that transient attack is the fastest possible while delivering the maximum energy available from the amplifier with minimal colouration.  A greater sense of immediacey than is possible with a fully soldered path.

Liquid Tranquility!

                 The available finishes are as follows: the Monolith, top, back and plinth are finished in high gloss piano-black lacquer; the sides are veneered. The choice of veneers are: American Walnut; Australian Oak; Australian jarrah ( alternative standard finish if a darker colour is preferred ); West Australian Karri; West African Koto ; Canadian Rock Maple; West African Sapele (Mahogany ); Tasmanian Ash; Tasmanian Oak ( standard finish ); Tasmanian Blackwood; American Cherry; and White American Oak; There are innumerable veneers available; please inquire! Or any plain solid colour. Even Black and White4.

                The  PandaTM  Model 10 Loudspeaker’s are all custom built and take from 6 - 9 weeks to fabricate and test prior to despatch and delivery. The Bocchino Audio  direct price per pair is $32,300.00 per pair  (Australian Dollars)  with freight extra!!.  ( 8 x  MECADOS & 8 x FM3 Fine Silver Spade lugs are included in this price). The price is essentially a wholesale direct price. The PandaTM  Model 10 Loudspeaker is not available wholesale anywhere. The thoroughness of the bare wire design, individual testing of all components and correct electrical and mechanical matching of all elements for the construction of the PandaTM  Model 10 Loudspeaker are unprecedented in loudspeaker construction.

Warranty is parts only for 3 years. Fusion of voice coils from owner abuse is not covered.

Though I recommend up to a 400 watt amplifier to drive the Panda'sTM  a 60watt triode Audio Research Classic 60 copes handsomely.

Speakers should not be played at their ear-splitting limit but at normal listening levels in order  to take advantage of a large power reserve and allow the amplifier to rise as necessary and when needed. The amplifier fitted with Monopoles®: of course!.

The Panda'sTM are also available with their own dedicated electronic crossover ;   normal supply  is with a passive crossover.  B.A.S.S. StraightTM Speaker Cable is also available, and highly recommended.

All PandaTM Model 10 Loudspeakers are built and tested and tuned by the designer: Carmine Bocchino. There is no subcontracting of the assembly and testing. There are no shortcuts.
