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 stroke. 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 through anything, 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.

Dayton Audio PA465S-8 18" Pro Subwoofer 4" VC 8 Ohm
Dayton Audio PA465S-8 18" Pro Subwoofer 4" VC 8 Ohm is rated 4.75 out of 5 by 4.
Rated 5 out of 5 by from EXCELLENT driverJust completed a nightclub sub using two of these Clydesdales. Impressive motor strength. With each thump, the cabinet scoots across the shop floor. Solid first octave ("rap") bass without over excursion. Enclosure is @ 13 cu.ft., vented with two 6" Precision Ports, 6" long.

Rated 5 out of 5 by from No Brainer....Don't let the Price Fool You!Massive power handling, HUGE Xmax, near perfect match (WinISD) for around a 7cu.ft. reflex box, all for under two bills? What's not to love? I replaced the stock drivers in my two Yamaha SW118IV boxes with these.(required minor box modifications to fit) and they performed so well I custom built two identical boxes and all four are loaded with these drivers. They hit way harder and go deeper than the stock drivers and while I had to add some internal bracing to stop the rattles on the stock boxes (1/2" plywood), the custom built boxes (3/4" birch plywood) are just plain solid and tight with massive bottom end and no cabinet rattles whatsoever. These subs hit hard and deliver solid clean bass all the way down to my HPF cutoff point @40hz.. They are a bit power hungry though so you need to feed them well else they just sit there and laugh at you. They will work "ok" off of less power but give them 1-2K watts per sub and they really come to life. Mine are used for live sound and crossed @100HZ and powered off of a QSC PL380 and yeeaaaahh........makes a grown man want to sit up and beg for buttermilk!

Rated 5 out of 5 by from More than expected!With all the subs out there that are several hundred dollars more, you wouldn't expect as much from a sub that is now less than $200, but wow what a surprise! I am amazed at how good this one sounds, even with low base (in the 20hz range) this sub puts out. I've listen to many different sound tracks from classical to rap and tested it in free air and in a 3 cu. ft. vented enclosure. The sound is clean, upper bass (@110hz) sounds tight and controlled while still being able to extend into the 20s before rolling off (f3). It is a tad bit less efficient and likes a lot of space, but when I got close to the 1000 watt range it started jumping like a rabbit in a forest fire. I am driving it with a KRELL KAV-2250 and a KRELL Showcase preamp crossed at 100Hz 12db. What sold me on this model was the 11mm Xmax.

Rated 4 out of 5 by from concert touringI have replaced all 16 of my McCauley 6258 18's with these. I could not believe how well these subs project a 38 to 90 Hz frequency band into a 37,000 sq.ft. arena.( Chest crushing bass ), very clean bass too, at 142 spl . No adhesive problems and they behave better at twice the input power. Power compression is not an issue either, I was expecting a little bit feeding them with 2 Lab Gruppen FP10000Q amps. seriously, these speakers are the real deal. They are not the typical China cones that look good on paper, but sound worse than a worn out 6x9 car speaker once it's put into the correctly calculated box. Excellent subwoofer .

Dayton Audio PA465S-8 18" Pro Subwoofer 4" VC 8 Ohm

The specs listed here are not even close to the ones posted on Dayton's website.  Which ones are correct. Daytons site has qts at .57, a *VERY* different driver indeed. 

Asked by: Badman Sound
Dayton is currently in the process of updating specs for all drivers. The specs on their website are going to be the most up to date.

I have four single 18" slot port cabs measuring 28"H x 22"W x 22"D would these 18" subs perform well in those boxes? I am not sure what the box is tuned to the company that makes the boxes are Seismic Audio the model is SAP-18SFF if you wish to see them..

Asked by: CharlesD72681
Yes these woofers should work well in those enclosure volumes. Without knowing the tuning frequency I can't give you any numbers, but they are probably tuned around 45-50 Hz.

What is the actually raw driver weight? If it's really about the same as the ship weight, that's good enough (hence, if it just ships in a cardboard box and ship weight is within 1-2 lbs of actual driver weight?

Asked by: BradyMikesell
The drivers weight is about 35 pounds.
Answered by: MattW

Are these drivers really 34 lbs? Or is that ship weight?

Asked by: BradyMikesell
The weight listed online is the shipping weight.

What would be the outside measurements for a slot port tuned box  tuned to 36 Hz using 3/4 inch wood for a dual 18 design with a divider between the two drivers ?

Asked by: TranceRaver
Overall external dimensions would need to be 24"H x 40"W x 20"D with two slot ports (one for each woofer) that measure 22.5"H x 2"W x 15"D.
