OTTOMILA
The 8000 Series can be considered the direct heir to the legendary 7000 Series which enjoyed considerable successes in the world of Italian car stereo and beyond. We renewed a range of speakers already in itself exceptional, with the aid of the best technologies available.

Elevated To Perfection
The 8000 Series can be considered the direct heir to the 7000 Series. The goal was to renew a variety of speakers in itself exceptional, with the help of the latest technologies and the use of the best materials available today, always with installation versatility in mind. Key to the development of this type of car speaker system was to build on their exceptional musicality. In the 8000 Series, every detail was treated with the utmost care, from the choice of materials, the forms, construction and finishing of the baskets, to the ventilation systems of the magnets and voice coils. We have improved what was thought to be difficult to improve and we strongly believe we have laid the foundation for a new series of exceptional car speakers.
8000 Series - Tweeters
Main Construction Features
• The large 28 mm diameter voice coil is the best compromise between the lightness of the standard 25 mm coil and the great power management of 32 mm coils. This perfect combination of power and lightness is necessary for a tweeter that must reproduce frequencies in a linear and faithful way, even beyond the threshold of audibility. The voice coil uses an aluminum support to better disperse the temperature.
• Body made of 7000 aluminum alloy and brass, manufactured entirely by numerical control (CNC). This makes the structure very rigid with practically zero tolerances, yielding consistency of performance and maximum linearity of reproduction, free from any vibration and/or resonance.
• Torcon® soft dome, an exclusive Polyphenylene Sulfide (PPS), with a high-performance fibers, offers superb heat resistance, low weight and excellent self-damping, resulting in a resonance-free frequency response over the audible frequency range.
• O52 oversized, high quality neodymium magnet. This “motor” guarantees a perfectly linear response and constant magnetic flux over the entire working range of the tweeter, assuring an extremely linear and neutral response both at low and high volumes. Furthermore, a pure copper ring was added to reduce harmonic distortions.
• A careful study supported by FEM analysis allowed us to design the metal parts of the magnet to maximize the flow exactly around the voice coil, and make it linear throughout its entire excursion. Ventilation is ensured by a large opening on the bottom, protected by a filter with calibrated holes. This solution also reduces the peak impedance to the resonance frequency, making the tweeter easier to interface with any passive crossovers.
Passive Crossover
Main Construction Features
• Multi-amp or single amp connection.
• Clear acrylic cover for better ventilation and component protection.
• Gold-plated spacers and screws.
• Gold-plated, large diameter parameter adjustment jumpers for zero resistance and ultra-high load capacity.
• Air wound coils to minimize distortion.
• Large diameter (1.5 mm), 99.9% pure copper coil wire.
• Anti-inductive resistors with dissipating aluminum body helps to manage very high power while remaining relatively cool and maintaining consistent resistance.
• Very high quality bi-metallized capacitors for maximum transparency of details in the mid/high frequencies. To increase the response speed, the tweeter uses a configuration of lower value capacitors in parallel.
• Compact size and practical mounting system with 4 screws.
The UMA unit
This special and exclusive component driver is a concept born way back in 70's. Its aim is to concentrate midrange and tweeter emissions in a virtual single point. This minimizes phase delays and irregularities at the crossover point (you can read more in The Phase).
All the parts that make up this component have been made with the CNC process. This is very expensive and time consuming, but ensures perfect geometry and impeccable aesthetics. A mix of precious materials such as brass, stainless steel and Avional aluminum are used together for a unique product.
Each component uses a very large, vented neodymium motor magnet, optimized with computer simulations (FEA) to obtain a greater efficiency and improve linearity all along the voice coil’s excursion. The neodymium magnet is a high-grade type to eliminate magnetic loss at elevated temperatures and concentrate more force in less space.
The tweeter uses a Torcon® soft dome, an exclusive Polyphenylene Sulfide (PPS) with a high- performance fibers that offers superb heat resistance, low weight and excellent self-damping, resulting in a resonance-free frequency response outside the audible frequency range.
The midrange’s non-pressed, cellulose pulp exponential cone, with a Vinylester resin coating, ensures a perfect balance between rigidity, weight, and self-damping. The cellulose pulp guarantees an extremely natural and linear reproduction, with an excellent extension at high frequencies.
8000 Series - Woofer
Main Construction Features
• Basket made of 7000 aluminum alloy manufactured entirely by numerical control (CNC). This makes the structure very rigid and with practically zero tolerances, yielding consistent performance and maximum energy transfer from the voice coil to the cone. Moreover, there’s an increase in efficiency in the low range and absence of resonances in the medium/high range (only with Limited Edition Speakers).
• Cone and dust cap made from unpressed paper, yielding the best compromise between damping and rigidity for an extremely natural sound without colorations or alterations. A water repellent treatment also makes it suitable for applications in harsh environments.
• Oversized magnet. The high-quality magnet (Y-35) guarantees a surplus of energy that makes the excursion peaks easily reproducible by this woofer. Even at high excursions, the coil works quietly in its magnetic field.
• A careful study supported by FEM analysis allowed us to design the metal parts of the magnet in order to maximize the flow exactly around the moving coil, and make it linear throughout its entire excursion. Ventilation is ensured by a large opening at the bottom where its shape reduces turbulence noise to inaudible levels.
• The exclusively designed clamp accepts large gauge cables.
• The large diameter voice coil uses an aluminum support to better disperse the temperature. Furthermore, the entire voice coil is exposed to outside air through large slits in the basket (protected by a dust filter).
