Eikona 2 Reflex 7

A compact bookcase or stand mount loudspeaker, capable of reaching 55Hz. Ideal as a monitor or satellite system.

Eikona 2 VTL

Ted Jordan's famous VTL transmission line enclosure. Originally developed for the JX92S it works even better with the Eikona 2 and is capable of fullrange performance to low bass. Its unusual wide baffle makes it very room-friendly and adds an engaging depth to the sound.

Eikona 2-38 MLTL

A brand new MLTL transmission line deigned for us by Mark Dikovics. This tall, slim enclosure has a f-3dB point of 27Hz and is capable of handling the full orchestral range.

These specifications are from production units. They are a combination of direct measurement and computer measurement For more details of our reservations about computer measurement, please refer to our article The Parameter Game and the Jordan Manual Chapter 6 both of which can be found in ARTICLES.

Meaurements are on-axis rather than the 10 degree off-axis measurements which are often used (but not acknowledged) to give a more flattering result.
