Forget “hard to drive” speakers. Heretic loudspeakers are engineered to work with all amplifiers, including high quality, low power, “tube” amplifiers. Sensitivity rating of 97 dB @ 2,83V and non-inductive tuning means that most of the time, your Heretics will be perfectly happy with less than 1 watt of power.
Point Source Co-axial Transducers
All sounds originates from a single point in space. No transducers all over the place, yielding fuzzy, phasy music reproduction. Excellent soundstage, precise location of instruments and coherency.
Obsolescence is Obsolete : 10 years warranty
No software updates, no drop outs, no electronics to fail, no tracking software or DSPs… Nothing can be simpler: hook your amplifier, play your favourite music, that’s it and backed by a 10 years warranty.
FSC Birch Plywood construction
Heretics are built from, no void, 12 ply ultra-premium birch plywood.
Why? Because of tone. Plywood, unlike energy robbing MDF, has a tone that isn’t matched by any other material. Tone comes from rigidity, lightness and compliance. But not too much! How much is perfect is our trade secret, and we would love you to find out!
This is one of the reasons that all Heretic Loudspeakers are renowned for their musicality, tone, punch and lively sound.
Their full range sound is incredibly agile and fast. The A614 offers nimble bass, with a nice and generous tone around 40 Hz and super tight impact, and they are superbly linear from 100 Hz up to and above 22 000 HZ.
Heretics are available in Natural and White Wash, and is also available in a Western Black Patina – 1930s and 1940s non-color, somewhat black, like a dark chocolate almost charred surface. The patina is achieved by multiple coats of pigments and the same number of ultra fine grit hand sandings, followed by a thin coat of bee’s wax, and all colours are supplied with a Mellotone grille.
Heretics are designed to work with your room and not against it. There is no need to place them in the middle of the room : place them close to the front wall and your room will be filled with true, lively and musical sound. The unique ductless design does not produce the dreaded one-note-boom sound of conventional speakers.
Most loudspeakers have a circuit called “Baffle Step Compensation filter” to compensate the acoustic effect created by narrow enclosures, that boosts low frequencies. Heretic speakers do not have this circuit and rely on the “broad shoulders” of the enclosure, acting as a launch pad for low frequencies. Therefore, it is advisable to place Heretic speakers against the wall and benefit from the reinforcement offered by your natural room acoustics.
One of the secrets of Heretic’s musicality is found in the premium, exotic serial network topology using premium parts such as high gauge Air Core Solen inductiors, Mundorf Capacitors and non-inductive high power, paired resistors on Mil Spec printed circuit board.
No formaldehyde, no COV. All Heretics are finished with water based acrylic or food grade 100% vegan linseed oil and pure Beeswax.
