Classic 99
A down-firing 12-inch driver and 450-watt Class D amplifier give Classic 99 more physical capability than Classic 98 while retaining the same furniture-led direction. Selection should follow system scale and room behaviour rather than model hierarchy alone.

WHO IT IS FOR
Who it is for
Primary roles
- For music-led systems seeking more scale than Classic 98, while keeping walnut finish and a deliberately traditional visual character.
ARCHITECTURE
Understand what each feature means in a complete system.
Installation and integration
Add 44.5 mm rear depth when the High Level connector is installed. Verify High Level wiring against the amplifier design and use safe handling for the 22.4 kg cabinet. Do not vertically stack Classic 99.
SYSTEM / ROOM MATCHING
Will it fit the system you already own?
We consider connections, room context, installation and your listening priorities together before suggesting a configuration.
What to check for your system
- Provides High Level, low-level RCA and LFE RCA connections.
- A candidate where the system and room assessment supports the larger Classic cabinet and driver.
- Do not choose it over Classic 98 from hierarchy or room area alone.
What to keep in mind
- 24 Hz is a manufacturer -6 dB specification.
- The official technical table states 450 watts; a conflicting 300-watt FAQ statement is excluded. The 24 Hz figure is a manufacturer -6 dB specification.
- The model is not designed for vertical stacking.
ROOM & INSTALLATION
What to confirm before choosing the final configuration.
- Rooms with confirmed space for the taller cabinet and sufficient freedom to test a down-firing subwoofer away from unsuitable boundaries.
- Measure modal peaks, cancellations and decay before assuming the larger model is automatically the better choice.
