EJ Jordan Eikona 2 drive unit

The Eikona 2 is the latest drive unit from EJ Jordan Designs. Building on the success of the Eikona 1 and the famous Jordan JX92S, the Eikona 2 is a world-class, fullrange drive unit capable of covering the whole spectrum of orchestral music, from 30Hz to over 20kHz.

The Eikona 2 features:

- a circular, diecast chassis for ease of mounting

- larger production quantities to meet demand

- refined driver parameters with increased sensitivity

- even better performance at HF

- true, wide bandwidth performace from 30Hz to over 20kHz.

The new Jordan Eikona 2 is designed in the UK by Ted Jordan and manufactured in Denmark by Scan-Speak A/S. This combination of the UK's legendary loudspeaker designer and Europe's leading drive unit manufacturer has resulted in a true high-end, audiophile loudspeaker.

The Eikona 2 costs £155.00 (excluding VAT) and is available immediately. To order, please see the CONTACT page.

Please note that these specifications are from production units and 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.

The 10 degree off axis measurement gives a flatter frequency response. This is often used within in the industry without acknowledging it as such.
