Dayton Audio Epique E180HE-44 7″ DVC MMAG Extended Range Subwoofer 4 Ohm per Coil
Combining world class performance with a reasonable cost, the Epique E180HE-44 7″ carbon fiber cone woofer from Dayton Audio sets a new standard in versatility, distortion, and response for small speakers. This dual voice coil driver uses a patented MMAG dual gap motor assembly for unmatched linear excursion capability to create compact systems with more bass output and lower distortion than ever. Featuring a carbon fiber cone, dual voice coils, custom tooled suspension, FEA optimized motor, cast aluminum frame, ample venting, and extensive induction control, the E180HE-44 pushes the limits of performance for a 7″ driver. Capable of exceptional performance in everything from small subwoofers to 2-way designs, this versatile driver will redefine what is possible from compact speaker systems.
MMAG motor assembly – like no other
MMAG = Multiple Magnet Air Gap
The heart of the E180HE-44 is the patented MMAG dual gap motor assembly. This unique design uses 2 top plates spaced between 6 smaller bucking magnets creating a longer magnetic gap with more consistent flux than more common dual gap arrangements. The combination of the MMAG motor and the underhung voice coil gives the E180HE-44 zero loss of motor force (Bl) even when driven to 10 mm of excursion, and an overall excursion capability of over 14 mm (at 70% Bl). This incredible excursion capability allows extremely low harmonic and intermodulation distortion to ensure remarkably clean output even when driven to high output levels. Furthermore, the motor includes extensive induction control to lower Le and improve high frequency response.
Carbon fiber is all about performance
The rigid carbon fiber cone gives the E180HE-44 a unique look while offering a number of performance advantages. With one of the highest strength to weight ratios of readily available materials, carbon fiber keeps the moving mass to a minimum enabling extended low frequency extension without sacrificing efficiency. The woven cone has excellent damping properties which keeps unwanted resonances under control for incredibly smooth response all the way up to 3,000 Hz. Optimized cone and dustcap profiles make sure that there is no deformation when exposed to high stress so the smooth response and low distortion remains consistent even when pushed to high output levels. Finally, the outside edge of the cone has been reinforced to further control cone breakup and help maintain controlled off axis dispersion.
High excursion requires flexible suspension
When designing the E180HE-44, Dayton Audio paid extra attention to optimize the suspension to guarantee unrestricted excursion without limiting performance. The large roll rubber surround was custom tooled for high excursion while paying extra attention to the profile to avoid limiting off axis dispersion. A filleted inside edge helps to add extra damping to the cone while reducing reflection from the high roll surround to further improve higher frequency response. A large diameter progressive spider helps keep the cone linear when driven to high excursion without restriction. In addition, the tinsel leads have been woven into the spider on opposing sides to keep mass and compliance displaced evenly across the spider.
Extensive venting helps displace unwanted heat
Excess heat build up will increase resistance and cause significant power compression and even failure. The force air across the voice coil and keep everything cool the E180HE-44 has extensive cooling. Another advantage of this MMAG motor assembly is the open spaces between the bucking magnets which allow unrestricted airflow directly into the center of the magnetic gap. With this open layout cool air is pulled directly across the voice coil to remove heat more efficiently than more common motor designs. Also the E180HE-44 includes a vented voice coil former, 3 large peripheral gap vents, and unrestricted airflow under the spider to make sure that every component has fresh air moving across it to keep temperatures at a minimum even when pushed hard for long periods.
Cast aluminum frame holds everything together
In order to support its massive motor assembly while providing a solid mounting surface, the E180HE-44 uses a rugged cast aluminum frame. The minimalistic design of the frame eliminates unwanted reflections and provides ample airflow for the rear of the cone. With plenty of space behind the spider makes sure that you can push the limits of excursion without bottoming out. Being a non-magnetic material, the aluminum frame has no effect to the magnetic field allowing the motor to effortlessly perform exactly as designed. As an added bonus aluminum is an excellent conductor of heat to further assist in cooling.

Explicatii in ceea ce priveste rodajul echipamentelor, cat si al cablurilor, asezarea optima a echipamentelor in camera de auditie, importanta acusticii camerei si nu in ultimul rand sistemul de alimentare a intregului echipament:
PENTRU BOXE:
- Pentru performante optime este necesara pozitionarea boxelor la o distanta de minim 30-40cm de peretele din spate pentru boxele cu bass-reflex in spate, pentru cele cu bass-reflex in fata, recomandam pozitionarea la o distanta de 10-20cm fata de peretele din spate, dar totodata la o distanta de cel putin 50cm fata de peretii laterali. Tineti cont de faptul ca orice piesa de mobilier din incapere, joaca rol de absorbtie fonica, dar si de difuzie fonica daca acestea din urma sunt din materiale ceramica sau oglinzi, geamuri sau alt material reflectorizant. In acest sens, gasiti pe blogul nostru, multiple articole care va pot ajuta
- Boxele vor ajunge sa functioneze in parametrii recomandati de producator, dupa minim 50 de ore (ideal 100 ore) de functionare la volum mediu. In aceasta perioada de timp, de “rodaj a boxelor”, sunetul va fi la inceput mai artificial, bass-ul nu va fi inca controlat, inaltele rigide iar vocile usor retinute, pe masura ce boxele vor functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate. Exista boxe care necesita un „rodaj” mai amplu de minim 300 de ore mai ales in cazul celor care au difuzoare de kevlar, carbon sau alte materiale de acest tip. Boxele care se „rodeaza” cel mai repede sunt cele care au difuzoare de celuloza.

PENTRU AMPLIFICATOARE, DAC-URI, PREAMPLIFICATOARE, RECEIVER STEREO & HOME CINEMA, SURSE DIGITALE AUDIO-VIDEO:
- Pentru performante optime este necesar „rodarea” echipamentului, In functie de complexitatea componentelor din aparatul dumneavoastra acesta poate dura intre 30-200 ore.
- Rodajul se face la volum minim, fiind astfel suficient faptul ca acesta este alimentat corect conform manualului de utilizare la 220-230 Volti si trece semnal audio sau video dupa caz prin el.
- Echipamentul supus „rodajului” va ajunge sa functioneze in parametrii recomandati de producator, dupa perioada mai sus mentionata. In aceasta perioada de timp, de “rodaj”, sunetul va fi la inceput ceva mai artificial, bass-ul nu va fi inca controlat, inaltele rigide iar vocile usor retinute, pe masura ce echipamentul va functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate.
- In ceea ce priveste echipamentul video precum videoproiector, TV, media player, blueray player, necesita un "rodaj" de cel putin 50 de ore. Lipsa acestuia nu va poate oferi maxim de performanta. "Rodajul" se efectueaza prin simpla utilizare a acestuia, intr-un mod conform specificatiilor mentionate de producator.
PENTRU CABLURI:
- Pentru performante optime este necesara „rodarea” cablurilor, In functie de complexitatea conductorului folosit, cat si geometriei acestuia, „rodajul” poate dura intre 30-100 ore.
- Rodajul se face la volum minim, fiind astfel suficient faptul ca va trece semnal audio sau video dupa caz prin el.
- Cablul supus „rodajului” va ajunge sa functioneze in parametrii recomandati de producator, dupa perioada mai sus mentionata. In aceasta perioada de timp, de “rodaj”, sunetul va fi la inceput ceva mai artificial, pe masura ce cablul va functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate.
