The components

Sealed 2-way · D'Appolito

A closed 2-way speaker built on the D'Appolito principle. Full-range capable with a surprising amount of bass extension, but limited to moderate sound-pressure levels — a well-suited entry-level master monitor for smaller rooms. It is typically paired with at least one Model 9 per side. Active design, driven by two amplifiers: one for the tweeter and one for the two midrange drivers.

Classic 3-way

A classic 3-way system, running full-range with a 9″ woofer. The sealed design delivers extremely precise temporal resolution in the bass region. Each driver is powered by its own dedicated amplifier.

• 9″ woofer
• Sealed enclosure
• One amp per driver
• 27 kg

Bass extension module

A 9″ driver in a sealed enclosure with its own amplifier — noted for its speed and fast transients. It complements the Model 515 or 519, with drivers selected for harmonic cohesion. When paired with a 515, one Model 9 is placed above and one below.

DSP crossover & controller

A DSP-based crossover with additional features. Four inputs (analog plus two switchable AES/EBU digital), eight analog outputs to feed the amplifiers, and Ethernet control via software. 120 dB of dynamic range with linear converters. It enables full room calibration and removes the need for a separate D/A converter.

• 4 inputs (analog + AES/EBU)
• 8 analog outputs
• Ethernet control
• 120 dB dynamic range
• Room calibration
