Coaxial speaker SEAS C18EN002/A, 8+6 ohm, 6.9 inch

A low-mass, surface-treated aluminium/magnesium alloy cone behaves like a piston throughout the audible frequency range, without any sign of midrange resonances.

The coaxially mounted aluminium/magnesium alloy dome tweeter has a low resonance frequency, and integrates with the cone driver to form a point source.

The cone profi le has been carefully designed to optimally load the tweeter's radiation. A completely new rubber surround reduces resonances and prevents surround break up in the midrange band. The surround's small inverted roll, combined with a profi le that follows the shape of the cone, results in almost total elimination of diffraction effects on the tweeter's output.

The powerful neodymium magnet system, with its small profi le and optimal shape, results in high midrange sensitivity with minimal back wave refl ections. Heavy copper rings mounted above and below the T-shaped pole piece reduce nonlinear and modulation distortion and increase overload margin. The crown-shaped copper tweeter support ring eliminates any resonance coming from the cavity between the tweeter body and midrange voice coil former.

All of these features work together to provide a smooth and well behaved off-axis response throughout the entire operating range.

The resurrection of the E0057-08/06 is finally here. The E0060-08/06 is the new and improved version, and from September, it will replace the E0057.

A few years ago, SEAS launched a superior coaxial midrange driver named C18EN001/M.
The product was sensitive to extreme environmental conditions, and because of this, we decided to withdraw it from the market.
Since then, we have spent time improving the design, and have now come up with an improved driver that outperforms the previous one.
The new driver utilizes a cone and tweeter diaphragm with a white coated aluminum/magnesium alloy.
The Neobase magnet system has a reinforced massive top plate to enhance stability and good coupling between the magnet system and basket.
The E0057-08/06 is dead. Long live the E0060-08/06 C18EN002/A!

History of the King Coax

This has been an important project for a long time at SEAS. It all started when one of our studio monitor clients asked us to develop a monitor, a midrange coax and a 22cm woofer. We decided to create the best coax speaker we possibly could.

The special part of this unit is the midrange midrange-coax, with a large midrange membrane, which does not require much movement. This gives the tweeter the best possible working conditions.

The King Coax received its name from the copper ring under the tweeter. When we opened up the ring to reduce the dip in the frequency, it resembled the look of a crown. A coax with such good results and a crown, the name King Coax seemed to fit perfectly.
