Product Details
Dayton Audio PN470-8 18 NEO Series Pro Woofer with 4 Voice Coil 8 Ohm
Dayton Audio left no boxes unchecked on the PN470-8 woofer. It features high power handling, 4 inner and outer wound voice coil, glass fiber former, powerful FEA optimized Neodymium motor, ribbed paper cone, and a copper cap on top of the extended pole piece. Thanks to the lightweight motor assembly, the PN470-8 weighs in at only 16.5 lbs, 30% to 50% lighter than a comparable ferrite driver, making it Roadie approved and perfect for mobile DJs and portable PA systems. The PN470-8 is an ideal driver for any high output 2-way and 3-way speaker systems, bass bins, or horn loaded designs.
Lightweight but Powerful Motor Assembly
The lightweight but powerful neodymium motor assembly on the PN470-8 has been FEA optimized to provide a combination of low distortion and high efficiency. With the large neodymium magnet mounted inside the voice coil nearly all of the magnetic strength is concentrated into the magnetic gap providing up to 40% better utilization than conventional motor designs. The extended pole piece includes a large copper cap helping to lower distortion and linearize inductance.
Rugged Construction and Suspension
To stand up to the use and abuse of the professional sound environment Dayton Audio made sure the PN470-8 can take a beating. The cast aluminum frame uses 8 wide spokes to firmly support the motor assembly, and the thick mounting flange is reinforced to create an incredibly solid mounting surface. The cone, constructed of thick paper for a natural response, includes glass fiber reinforcement and uses a ribbed design offering additional structural support. Supporting the cone is a heavy spider with integrated silver tinsel leads and triple roll treated cloth surround, both designed for high excursion applications allowing the PN470-8 to handle short bursts of excessive power without damage.
High Power Handling and Low Power Compression
Along with high efficiency, you need a lot of power to achieve extreme SPL levels. Capable of handling up to 800 watts RMS and 1,600 watt peaks, the PN470-8 can take the heat. The 4 voice coil uses a vented fiberglass former with an inside/outside winding configuration which doubles the coil's exposed surface area for improved heat dissipation. The motor assembly includes a large pole vent along with 8 large peripheral vents in the voice coil gap to keep fresh air moving across the coil keeping the temperature at a minimum. Finally, the frame has venting behind the spider with integrated heatsinks removing as much heat as possible from the sensitive motor and voice coil.

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.
- 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 ceva 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.
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.
