Dayton Audio Reference RSS265HF Box: Ported 10" Professional Series Enclosure Single 10" Ported enclosure

Sealed, the RSS265HF is listed in our sealed wedge (PO 10-S W RSS265HF) at 1.49 cubic feet, Qtc 0.68, half power 40 Hz. The slot is gated at 420 W: the channel runs 16.7 m/s and the mouth 8.6, and the cone peaks at 8.3 of its 12.3 mm with the subsonic filter in place. Passband ripple is 1.6 dB. The RSS265HF-8 (single 8 ohm) was run through the same cabinet: F3 32.0 Hz, passband ripple 2.4 dB, 7.7 of its 14.3 mm at 350 W. Tuning is chosen for in-car response rather than an anechoic curve: a vehicle adds roughly 12 dB per octave below about 45 Hz, and this tuning is where that sum comes out flattest across 25 to 60 Hz.

The Reference RSS265HF also builds in the Performance Optimized ported wedge and ported down-fire, the smaller and cheaper boxes. The Professional cabinet is the step up for it: a 2.25 inch three-layer baffle with the woofer flush in the outer layer, and a slot port gated at 420 W. It carries a 2 year warranty, against 1 year on the Performance Optimized lines.

Threaded inserts pressed into the baffle on the published 9.764 inch bolt circle, stainless machine screws included. The inserts are in the baffle when it arrives; the machine screws are in the terminal cup bag.

Yes, at 25 Hz, 24 dB per octave. Below tuning a vented box stops loading the cone and excursion runs away toward DC. With the filter in place this cabinet puts the Dayton Audio Reference RSS265HF at 69 percent of its usable travel at 420 W.

Not one we can show you. We do not build a sealed enclosure for the Dayton Audio Reference RSS265HF and Dayton Audio publish no sealed volume for it, so the Performance Graphs tab carries no ported-versus-sealed chart: the only sealed box left to plot would be this cabinet stuffed and sealed, which nobody would build, and a comparison against it would tell you nothing you could buy. What a vented box gives up is the region below tuning, where the cone unloads and the 25 Hz subsonic filter takes over; around 31.5 Hz the vent carries the load and cone travel drops to its minimum, which no sealed alignment can do.

It is a vertical slot beside the woofer, the full height of the cavity, 1.25 inches wide and 15.6 square inches. It runs 6.00 inches to the back wall and turns once along it for 20.28 inches; the fold costs about 1.5 Hz and the port is cut for it. The channel runs at 16.7 metres per second at 420 W, 49 percent of its turbulence limit, and the mouth edges carry a 1/2 inch roundover so the air leaves the face at 8.6 metres per second against the 17 metres per second threshold where a slot starts to chuff.

46 lb, 30.00" W x 14.00" H x 11.00" D external. Every Professional cabinet is priced the same way, by its size: this one is 2.67 cubic feet outside. Delivery to the 48 states is inside the price; it ships as a 46 lb parcel and checkout adds nothing. The $-2 difference is the larger box and the port this driver needs to run at its rating. Do not add polyfill; it ships dry on purpose.

No. This is an enclosure only, cut for the Dayton Audio Reference RSS265HF specifically: the 9.252 inch cutout, the 5.374 inch mounting depth allowance and the 1.09 cubic foot alignment all come from Dayton Audio's published parameters. It fits both Dayton versions, the RSS265HF-4 (single 4 ohm) and the RSS265HF-8 (single 8 ohm); the cabinet is tuned on the RSS265HF-4 and was run with the RSS265HF-8 too. Bring your own driver.
