"The Epic resurrection of the once British cult brand is a small loudspeaker sensation: a highly capable all-round loudspeaker that knows how to convince in both emotional and precision aspects."
LP Magazine 03.2023
Den originale ES14 ble lansert i 1995 og ble umiddelbart en legendarisk høyttaler som lydentusiaster snakker om den dag i dag. ES14N er utviklet av Karl Heinz Fink, vår tids kanskje mest anerkjente høyttalerkonstruktør, og mannen bak FinkTeam KIM og BORG. |
Konstruksjonsmessig er dette heftige høyttalere. Med stativer har den en samlet vekt på over 70kg, noe som ikke akkurat er barnemat for er relativt kompakt stativhøyttaler. :-) Her er det selve byggekvaliteten og størrelsen på magnetene osv. som speiles i den høye vekten - alltid et godt tegn.
Lydgjengivelsen fra ES14N er vanskelig å beskrive med noen få setninger, men stikkord er et utrolig stort lydbilde med masse oppløsning kombinert med klassisk britisk mellomtonemagi. Her lyder stemmer fløtemykt, men med realistisk anslag og driv. Bassen er rett og slett sjokkerende både god og dyp til en stativhøyttaler å være. Denne høyttaleren fyller selv store rom uten problemer. :-)
Informasjon fra produsent:
Mid/Bass driver
A 7“ driver designed for use in a ported speaker plus compensation for higher resistance air coil. Choice of Polypropylene as cone material was set from the beginning. Polypropylene is a nice material – very consistent, can be made with different filling material like MICA and it can even be injection moulded for funny shapes or variations in thickness. Combined with a low damping rubber surround, it delivers lots of dynamics with very low colouration.
The 36mm voice coil of the unit was a relatively straight forward choice. It uses a 18mm long 2-layer winding of copper wire on a non metallic TIL former (TIL is a Glasfiber/Epoxy mix ). The shape of the magnet was optimized, using simulation, to have the best linear BL behavior and a very low variation in inductance over the movement of the coil. This gives you the lowest level of linear distortion and Intermodulation distortion and is clearly different to the magnet system used in the old days. variations.
The main magnet is a Ferrite type, the flux compensation magnet reduces the stray field of the magnet and set the right BL for the cabinet size. A Neodymium disk on the pole piece made the BL more linear and a metal phase plug helps to move heat from the coil. All the parts are mounted into a very strong glass filled plastic basket made from scratch. The material was chosen for the combination of stiffness and good damping.
Tweeter
28mm VC for better performance at the lower end of the tweeter range. The dome itself is made out of an Aluminum alloy with additional ceramic coating to increase the stiffness. Together with the fabric surround and a shaped Mode control ring, the resonance peak of the tweeter is around 30kHz, shifting it out of the 20kHz limit of human hearing. The magnet system uses Ferrite magnets and an improved cavity combination to minimize distortion. Ferrite is the better material for a tweeter if a small size is not needed. It offers a lot more “air“ behind the dome and the surround and avoids compression and harmonic distortion because too small cavities.
A copper cap in the magnet reduces distortion and increases level at very high frequencies. The tweeter used no waveguide for sound reasons. To protect the dome, an oval asymmetric mounted perforated metal grill has been added. This part is not removable and was used during the voicing of the speaker. The massive metal plate of the tweeter is only touching the cabinet on 4 points around the screws (idea taken from Roy George of NAIM with his blessing) to reduce a transfer of energy between tweeter and cabinet baffle. The tweeter has its own cavity in the cabinet.
Stand
To give the speaker a home to sit on, a dedicated stand is available. The middle part is made as a massive wooden bar, combining 4 layers of wood, glued together with same damping glue used internally in the ES14N. The top plate is a double layer steel plate with a Bitumen layer in between and the bottom plate is a thick steel plate to hold adjustable spikes. The Speaker can be shipped without a stand, so other 55cm high stands can be used as well.
