E-Motion II

E-Motion II The E-Motion II is a development by Bernd Timmermanns, based on the Emotion. The Eton Air Motion Transformer ER 4 is surrounded by 2 Eton 7-372/32 HEX bass drivers, a configuration that many customers had asked for.
Technical data:
- impedance: 4 Ohm
- rated SPL: 89 dB (2.83V / 1m)
- frequency range (-8dB): 32-40 000 Hz
- crossover frequency: 1.3 kHz
- cabinet volume: 2 x 22 litres
- size (HxWxD): 95 x 22.6 x 53.5 cm
- speaker type: floorstanding bass reflex

Air Motion Transformers are folded ribbon tweeters, that produce an airy sound with the greatest of ease.

Review summary by Hobby-HiFi: "That's the speaker that is capable of reproducing every kind of material: soft or blaring, always with clarity and precision, without any exaggeration and with absolute attention to detail."

The kit consists of:
- 1x Eton ER4 tweeter
- 2x Eton 7-372/32 HEX bass drivers
- 3x polyester damping material
- 4x Bawotumex
- 0.5x foam sealing tape MDM-5
- 4x HP 70 bass reflex tubes
- 1x terminal with gold plated brass binding posts
- 20 x screws PAN 4x20
- 4 metre cable 2x2.5 mm2 for internal wiring
- 2 x LP 06 PCB's, non-tinned

E-Motion II, price per unit without cabinet and wood:   EUR 729,00

E-Motion II with high-end crossover

Especially the components in the signal path can be improved on. Our recommendation:
- the coil L1 should be replaced by a cfc12 copper foil coil.
- the 22 uF capacitor before the ER4 should be replaced by a Mundorf 22 uF MCAP Supreme.
- and the coil L4 should be replaced by a baked varnish coil.

with high-end crossover, price per unit without cabinet and wood: EUR 801,00

Hint 1: acrylic cover for the outside crossover upon request.

Hint 2: If no valve amp is being used R5, C5, L5 may be omitted
