"About the manufacturing process, as you guessed the wooden horns are made of two solid-wood halves. CNC machining first carves out the inner 2m channel in smooth curves, then the laminated wooden block's outer form gets worked into its final organic shape. The same procedure is applied to the other half and after final treatment and wiring the two clam shells are bonded together with glue and guide pins.

"The composite models too are assembled as two halves but here each is made with high-strength inner and outer walls which then are injected with a composite resin of very specific density to fix the resonant frequency of the material exactly where our designer specified it. Only then the two halves are bonded and finished in the final treatment. The upper spheres and lower bases are produced in the same way.

"We always market the MH Jazz horns with one or two active subwoofers. This was conceived as an inseparable and complete system. The pricing naturally accounts for this systemic approach. If someone were to order just the CH1 subwoofer—for perhaps another main speaker—its price is €4.700/ea. That subwoofer can be fitted with a stereo or mono amplifier and be finished in composite or various woods.

"As shown in these photos, the CH1's core is always composite. Its five-folded 4m line is kept very tight so as to not exceed reasonable dimensions. This precludes thicker more conventional building materials and makes our very strong low-loss composite truly ideal. The sides however can be solid wood or laminates painted in the desired color. If for example a customer wanted MH Jazz horns in Paulownia wood, the CH1 would sport Paulownia cheeks to match and its core would be painted the same color as the composite spheres atop the main horns."

The birthing process for these Croatian products is considerably more laborious than that of the ubiquitous rectangular box which dominates loudspeakerdom. In fact Ring Audio (completely justified I think) considers them works of art. That explains the various finish options, the need for compact dimensions to cohabitate in domestic environments (what good is art if it can't be enjoyed by many) and the willingness to let professional artists use the surfaces as canvas for their own inspiration.

With the horn's internals reminiscent of Sven Boenicke's solid-wood speakers from Switzerland, for about the same coin as his SLS model one here not only adds two complex active subwoofers into the bargain but acquires true three-dimensional wooden shapes, not flat-sided wooden constructions. It's the latter aspect which moves the Ring Audio MH Jazz from straight audio appliance into sound-producing modern sculptures.

"To give credit to all the people we're collaborating with, the person responsible for the concept and construction of Ring Audio electronics and wiring is Nenad Petris, B.Sc., Electrical Engineering. Another person vital to our production is Mr. Vjekoslav Zelehovski, owner and manager of Tehnotrik in Zagreb. Tehnotrik handles the production of our composite products and applied material technologies. Our meeting with Tehnotrik three years ago has grown into a successful cooperation which laid the foundation for the commercial production of our audio products."
