They feature 4 quad-layer voice coils using an inside-outside winding technique, and dual spiders for extra stability.
Highlights
· 11 mm of Klippel-verified Xmax
· Inside/outside 4 diameter voice coils for maximum motor efficiency
· Ultra-rigid Kevlar-paper cones that resist deformation
· Extensive motor venting for elevated power handling and cool operation
· Copper shorting ring and pole cap minimize distortion up to the limits of excursion
· Rugged cast-frame construction with premium materials
Product Details
Dayton Audio PA465S-8 18 Pro Subwoofer 4 VC 8 Ohm
With over two decades of high-performance loudspeaker development experience behind them, Dayton Audio PA series subwoofers deliver powerful, dependable bass performance with all of the features and quality of pricey Italian-made pro subwoofers, but at a price that's a whole lot easier on your budget.
Klippel Optimized Motor Structure
The Dayton Audio PA Series subwoofers feature optimized motor structures that provide over 11 mm of Klippel-verified Xmax (10 mm coil overhang) with excellent symmetry and linearity, preventing distortion where it often begins – in the motor itself. Cleaner bass means higher impact, and better musical detail. The enormous high-grade ceramic magnet is economical yet highly efficient and stable, providing parameters that are a drop-in replacement for most existing pro audio subwoofer enclosures, but a significant upgrade in performance to most OEM drivers. The motor structure also features a copper shorting ring and copper pole cap to reduce flux modulation and inductance distortion, for massively powerful and clean sound at all output levels.
Advanced Cooling and Ventilation
The key to reliable, high-output bass is to get the heat away from the voice coil windings. The PA Series subwoofers feature 4 voice coils that use inside-outside windings, improving heat transfer and reducing power compression. The coils are also wound on fiberglass formers, which are much more resistant to heat-related deformation. Finally, the high-strength motor structures employ extensive venting, below the spider, through the pole piece, and into the gap itself.
Rugged, Reliable Construction
The heavy-duty cones used on the PA Series subwoofers contain a blend of Kevlar and paper fibers, for strength, rigidity, and durability, and the ribbed cone structure provides the necessary stiffness to withstand punishing bass transients. The cone and voice coil assembly is supported by a rugged long-throw suspension featuring dual spiders and a treated and deep-corrugated triple-roll surround, for clean and low-distortion excursion. The cone is coated to withstand incidental exposure to liquid, and the dust cap is anchored by a heavy bead of epoxy for dependable cone integrity. It's all held together by the finest adhesives and a tough cast-aluminum frame that's ready to take some road abuse.
When you're looking for a dependable, heavy-duty subwoofer driver to power your system's low end, choose the PA Series pro subwoofers from Dayton Audio! The 18 model is optimized for maximum deep bass extension in reflex-loaded enclosures. 15 model also available.

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.
Pentru detalii privind aceste aspecte de rodaj si nu numai, va rugam sa ne consultati!
