Epos ES-7N er en kompakt, toveis bassrefleks-høyttaler designet for å passe inn i bokhyller eller på frittstående stativer.

Den har en 5-tommers woofer av injeksjonsstøpt polypropylen og en 28 mm keramisk/aluminium-hybrid diskant. Kabinettet er laget av dobbeltlag MDF-paneler med selektiv avstivning for å redusere resonanser. Høyttaleren er optimalisert både for plassering nær vegg/bokhylle og frittstående i rommet (velges via bryter på delefilteret).

Med en følsomhet på 86dB/89dB og en impedans på 4 Ohm, er den en lett belastning for de fleste forsterkere.

Hvordan lyder den?

Lydmessig er Epos ES-7N er glede å lytte til. :-) Om du er ute etter en ultrapresis kompakthøyttaler som gir deg enorm innsikt i musikken og lydbildet er dette høyttaleren for deg. Bassen går selvsagt ikke kjellerdypt men den er virkelig engasjerende og gir et anslag og driv som mange større høyttalere mangler. Det at høyttaleren er så "rask" og lett på foten bidrar til at den er en av de mest holografiske høyttalerne vi kjenner til; ES-7N forsvinner rett og slett i lydbildet, og det man sitter igjen med er musikken. Den vil antagelig avsløre detaljer du aldri tidligere har hørt, spesielt i mellombassen og mellomtonen, men den gjør det uten noen gang å virke pågående eller slitsom. Rett og slett en uvanlig god liten høyttaler som vil gi deg lyst til å lytte til mer musikk. :-)

Informasjon fra produsent

The Concept
Many customers asked for a smaller speaker, so the development group created a smaller baby EPOS. This speaker should be a real bookshelf with a size small enough to go into typical IKEA designs for example. But how to make it?

Smaller speakers are especially giving the designer some severe headaches. This has something to do with the size of the front baffle and the small baffle’s influence on a speaker’s response curve. A design for free space should be different from one that plays close to a wall or inside a bookshelf.

In order to work in a semi-free space (some distance from a wall) and on a wall, the crossover filter can be changed with a switch on the backside of the speaker. Now, you are free to choose the place of your speakers without making compromises in tonal balance.

The Cabinet
The cabinet uses 2x8mm MDF panels with a high-loss damping layer in between to control unwanted resonances of the box itself. An additional wooden block on the top helps to optimize the Stereo image. Only a single brace was necessary to make the cabinet quiet. Four inserts on the bottom take 4mm screws, and the speaker comes delivered with silicon rubber spikes for good isolation between the speaker and the ground.
The stand for EPOS ES-7N should be around 70cm high.

The port tube is somewhat tricky, as it sits on the side of the cabinet – not the best place if you want to minimize the tube output of the standing wave modes inside the cabinet. So, finally, the solution is a bent port that ends up in the middle between the two side panels. It features selective damped ventilation holes in the middle and so controls the output in the critical mid-band very well.

The Crossover
The crossover features a switch to choose between two versions of tonal balance.
With the switch in the top position, the best placement is at some distance from a wall between 30cm and 50cm.
In the bottom position, the speaker should play close to a wall or inside a bookshelf. Please try both positions to find the best result in your room.

The response curve has been tailored to use the speaker in semi-free air or very near a wall. The bottom-end roll-off is flat to deal with the room/wall gain at low frequencies and to avoid booming bass. The speaker’s sensitivity is around 86dB for Position up and 89dB for Position down of the switch.

With the constant electrical impedance of around 4 Ohm and low phase shift, ES-7N is an uncritical load for amplifiers, making it possible to use many different types.

The Drivers
The 30mm voice coil with glass fibre/Epoxy former works in a magnet system with an impedance control ring to minimize distortion and Intermodulation. A double magnet compensates the stray field and increases the force of the coil. As in any such small speaker, the crossover must be close to the driver, and the compensation magnet helps to avoid interaction with the inductors of the filter.

The woofer is a new design, using – similar to ES-14N – Mica-filled polypropylene cone material made with injection moulding. A low hysteresis rubber surround and a Nomex high-temperature capable spider ensure the suspension is linear with good control of higher excursions.

The tweeter of ES-7N is identical to the tweeter of the ES-14N, giving the new model the same top-end quality. It’s a 28mm voice coil on an Aluminum alloy, ceramic-coated dome with a powerful Ferrite magnet and optimised inter-cavity airflow.

The tweeter does not use Ferrofluid in the gap for stable temperature and low compression.
