EPIC-5


A Studio Near-Field Speaker that meets the most important needs 

 

- Strives for perfect reproduction in all criteria without neglecting any one important feature.

- Avoiding any design compromises.

- A design, technically up to date, aesthetically pleasing implementation, carefully balanced.

- All at a reasonable price.

 

In detail

 

- For an even sound reproduction, we paid much attention to a linear signal response and the temporal, harmonic aspects. In and out swing behavior is balanced across the entire bandwidth.

- Equal material properties of the sound-forming components result in a homogeneous sound, none of the components gains the upper hand, which avoids having to artificially compensate any imbalances.

 

In-house development down to the last screw

 

- It quickly became clear that virtually no mass-produced components could be used for the implementation of a conclusive overall concept. 

- After four years of development work we are ready with developing all individual components as well as our own manufacturing process for the Epic 5!

 

Result 

 

- The Epic 5 gives a harmonious home to its perfectly balanced components — tweeters, woofers, passive radiators, amplifier electronics. It comes with a very elaborate, compact housing that is optimized for stiffness. 

- The wavefront timing of the components is mechanically aligned, they oscillate in phase and are phase-locked in the relevant frequency range.

- Low noise guarantees a very high dynamic range – decaying signals, such as reverb tails or the fading out of guitar strings will not disappear in the noise floor.

 

Purely analog!

 

- From the very beginning, we opted for a purely analog signal routing with high-quality components.

 

 

- Thus, the signal transmission takes place directly and unadulterated. Compensation using DSP calculation is rendered completely unnecessary.

Setup Recommendations

In order to achieve the best possible sound is highly recommended to not only consider the interaction between the loudspeakers and the surrounding acoustical environment but also the position of the listeneras relating to the loudspeakers. Here are some pertinent suggestions.

 

 

 

 

 

 

Distance and Level

 

The Epic-5 is of the type near-field, also known as meter-bridge-monitor. For the non-seasoned audio professionals the meter-bridge is the unit above large scale mixing consoles that used to house many VU meters (twitchy dials that give an indication of every channel-strip’s level).

Due to it’s intended positioning the Epic-5 is optimised for a relatively short distance. We recommend a listening distance between 0,8 m and 1,4 m (3 to 5 ft.). The Epic-5’s should be at ear level! The reference point for this adjustment is the space between the tweeter (High Frequency / HF driver) and the woofer (Low Frequency / LF driver).

At longer distance (over 1,4 m / 5 ft.) the high frequency response will decrease proportionally. Due to the attainable levels a listening distance closer than 0,8 m is not recommended!

 


 

 

 

 

 

 

 

 

 

 

Stereo Image

 

To achieve perfect stereo imaging please make sure that the position of the speakers–and the listener of course–are located symmetrically in the room. To clarify, if there are walls left and right, as there quite probably are, the distance from left speaker to left wall and right speaker to right wall should be (approximately) similar. The farther away the walls are the more leeway you have as the reflected sound will be delayed more.

 

Please male sure there are no obstacles between the speakers and your ears. Nothing that will obstruct or break the sound waves, like monitor screens, large leaf plants etc… Acoustically transparent elements can be placed there, but we can’t think of any qualifying items currently. Please let us know if you find exceptions to the rule!

The often quoted equilateral triangle is a practical recommendation, but depending on the spatial configuration of the listening room and the amount and quality of any reflections(primarily from the walls, ceiling and floor) it might be prefer able to move the listening position to a slot slightly inside the triangle.

An easy way to find the optimal listening position is to play a mono signal over both speakers, moving slowly back and forth until a solid phantom source is discernible in the middle.

 


 

 

 

 

 

 

 

 

Angle of the Listening Position

 

Please do NOT raise the back of the cabinet / turn the front of the cabinet into a vertical position. The inclination is needed to achieve perfect temporal alignment between tweeter and woofer.

 

 

 

 

 

 

 

 

 

In order to achieve perfect temporal alignment we recommend to NOT use your Epic-5’s on a writing desk or place them below ear level. Please make sure to use a stand or leveler to achieve the right position.
