C3 (pronounced ‘C-cubed’) Continuous Curved Cone™ design in the mid/bass driver ensures smoother high-frequency integration with the tweeter and superior bass dynamics. 

Sophisticated, clean and contemporary design with dark acrylic baffle motif mirrors the minimalist C3 Continuous Curved Cone™ profile. With a design taken from the Concept series but in a new housing, the high-frequency driver is fully hermetically sealed and mechanically isolated from the front baffle to protect from internal cabinet pressure and resonances from the mid/bass driver.

Ground-up mid/bass driver design delivers increased power handling. Point-2-Point™ (P2P) internal bracing stiffens the cabinet to minimize lower frequency vibrations, while focusing stereo imaging and improving soundstage. Helmholtz Pressure Equlizers (HPE™) reduces internal pressure and standing waves (5040 and 5050 models only).

Mid / Bass Driver Design

At the heart of the ground-up mid/bass driver design is the C3 Continuous Curved Cone™. The cone’s geometry requires good motor strength for optimal performance. Substantial magnets are coupled to large voice coils to increase motor strength – the result is a 50% increase in power handling and control over a comparable driver with 25.4 mm voice coil. The result is an improvement in the dynamic range of the speaker, especially in the bass region.

High-Frequency Driver Design

Based on the tweeter design principle found in the newest Concept series, the high frequency driver unit is hermetically sealed and mechanically isolated (floating) from the baffle to prevent internal pressure modulations from within the cabinet and adjacent mid/bass driver. The inner chamber is also carefully vented for lower distortion, with a lower crossover point for seamless integration through the crossover region.

C Continuous Curved Cone™

A genuine advancement in elements of mid/bass driver design, the C3 Continuous Curved Cone™ profile is the result of extensive research and expert engineering to combine the bass performance benefits of a traditional straight conic cone with the high/mid-range frequency control of a flared cone.

By creating a single, smooth, continuous curve profile, the advantages are clear. Its excellent dispersion, alongside its well-controlled frequency response and reduced harmonic distortion, enables smoother integration with the tweeter. Deep bass dynamics are also superior, with this and tighter, damped low-end sound allowing more flexibility in in placement of speakers near the wall boundaries of the listening room.

The 5000 series highlights a new terminal panel features metal securing nuts for low contact resistance and compatibility with 4 mm plugs, wires or spade tags. The terminals are very low profile to keep plugs close to the speaker back face, providing a tidy appearance and enabling the speaker to be placed closer to the back wall if required.
