Product Details

Dayton Audio PA385S-8 15" 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-inch 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 15” model is optimized for maximum punch in compact vented enclosures or folded horn applications. 18” model also available.

This is probably a rhetorical question, by optimum cabinet size > do you mean the best cabinet size to reach the lowest possible frequencies for this specific driver? If so, what is the recommended port to obtain this or possibly lower frequencies?

Asked by: daveapex3
The enclosure sizes listed in the spec tables online are considered by our modeling program as optimally flat alignments. If your intent is for lower bass, you will want to bump cabinet volume up and lower the port tuning a bit. I would recommend 4.7 cubic feet with a 6" diameter, 13" long port for a tuning frequency of 32 Hz and useable response to the low 30's as well.

Will recones or recone kits be available for this or the 18" version? Any idea on the price range if they are?

Asked by: ChrisVinSac
We will likely be able to recone them here but we will probably not have the recone kits available separately.

Will these new 15" and 18" Dayton pro drivers fit where their counterparts (PA380-8, PA460-8) are currently mounted (cutout and bolt pattern)? Thanks.

Asked by: Zhillsguy1
The bolt hole circle for the PA380-8 is 14.57" while the bolt hole circle on the PA385S-8 is 14.9".
