Product details
Dayton Audio RSS390HE-22 15 Reference Series High Excursion Subwoofer 2+2 ohm
The RSS390HE-22 15 Reference Series high excursion subwoofer from Dayton Audio will generate incredible bass response with unparalleled detail, control, and SPL capability.
Engineered for maximum linear displacement with extensive inductance control, this massive subwoofer produces unmatched low frequency extension and high output with the lowest possible distortion.
Optimized for small enclosures and with dual 2-ohm voice coils, the RSS390HE-22 is flexible enough to add breath taking bass to high output home and car audio designs.
Remarkably powerful low distortion motor.
In order to keep precise control of the cone when driven to high excursion, the RSS390HE-22 requires an incredibly powerful motor.
A stack of 3 high energy Y-35 ferrite magnets is used to provide the force needed while allowing ample clearance for the voice coil to travel without impacting the back plate. A copper ring and thick aluminum sleeve helps minimize stored energy and lower inductance as the coil travels through the motor.
This massive motor assembly gives the RSS390HE-22 the ability to produce extremely low distortion and accurate response even when driven to the limits of its 54 mm peak-to-peak excursion.
Amazing power handling with low power compression
Driving the cone is a large 3″ diameter voice coil wound on a thick aluminum former that is capable of dissipating enough heat to handle up to 800 watts RMS. A spiral spit in the former minimizes the eddy currents that are induced into any conductive former, to further lower inductance and distortion. The venting through the voice coil former and pole piece delivers ample airflow across the coil while minimizing turbulence to allow quiet operation when pushed to high displacement. In addition, the copper ring and aluminum sleeve improve heat transfer to the pole piece and magnet assembly, more efficiently absorbing heat away from the coil. All of this gives the RSS390HE-22 the ability to reliably handle tons of power without suffering from significant power compression, even when pushed hard for extended periods.
Optimized suspension for maximum linear stroke
In order to accommodate the 27 mm Xmax, the RSS390HE-22 required flexible suspension that permits linear movement to keep the voice coil centered even when driven beyond the limits of excursion. A custom tooled high roll surround maintains surface area and allows an incredible amount of travel without tightening up or distorting. Dual progressive spiders with integrated tinsel leads support the cone and voice coil. The spiders are optimized to begin restricting movement just as the driver reaches Xmax to protect from catastrophic damage in the event of excessive dynamic peaks. In addition, the spiders have significant space between them to keep the coil centered in the tight magnetic gap. Every aspect of the suspension on the RSS390HE-22 has been designed to reliably deliver extreme excursion capability without adding significant distortion.
Aluminum cone and dustcap… a Reference series tradition
To visually fit in with the rest of the popular Reference Series Subwoofers, the RSS390HE-22 uses a rigid anodized aluminum cone and dustcap. The cone is significantly thicker to withstand the force that will be applied with such a powerful motor and to increase mass for a low Fs. Thanks to the rigidity and natural damping properties of aluminum, any cone breakup is pushed well outside of the pass band giving the RSS390HE-22 exceptionally flat response, even throughout the mid-bass and lower midrange frequencies. In addition, aluminum is an excellent conductor of heat, turning the entire cone and dustcap assembly into a large heatsink that effectively wicks heat away from the voice coil to further control power compression.
Incredible flexibility to add powerful bass to any system
The specs of the RSS390HE-22 have been balanced to operate in a variety of situations. Extended low frequency extension makes it ideal for subwoofer use in home audio and theater systems. With extremely small enclosure requirements, the RSS390HE-22 is also an excellent choice for use in high output car audio designs. Also, dual 2-ohm voice coils allow for stereo 2-ohm or mono 1-ohm wiring configurations when connecting to high current car audio and professional audio amplifiers to extract maximum power. For home audio applications, simply wire the voice coils in series for a more common 4-ohm load for greater amplifier compatibility. All of the Reference Series HE drivers are built to provide amazing low frequency response with unbelievable power, impact, and detail.

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.

Tratamentul Acustic si Izolarea Fonica
Pentru un sistem echilibrat, trebuie tinut cont pe langa asezarea corecta a boxelor in incapere, al echipamentelor, sistemul de alimentare al acestora, tinand cont de instalatia electrica a locatiei.
