Dayton Audio SD315-PR 12" Passive Radiator
Looking to build a sealed box for my mains of my home theater, but would like to keep it sealed, yet get down to around 50Hz or less. How would one of these passives work with a Dayton R225-4 8" woofer?
A volume of 1.7 cubic feet with this PR will work well. With no weight added you will have a tuning frequency of 35 Hz and output into the low 30's.

Will this fit in your Trapezoid cabinet that comes with 11" hole, or is the hole too big?? I am not a wood worker LOL
Yes this will fit the cut out in that enclosure.

I have a focal 33v2 13 inch subwoofer 400 watts rms powered at 500 watts rms in a sealed 17inx17inx17in box. Would this passive radiator be a good match? Or is the box to big or also is the box to big for my subwoofer as it is. Thanks for the help.

I am considering using this (instead of porting) with a RSS210HO. Will it work well for this application? And if so what weight ballast would be recommended in the recommended ported box volume (1.68) to achieve the 27hz fs?
The ported volume on the site is actually not accurate and I will have this fixed. The recommended volume for this woofer using a passive is 1 cubic foot. With 200 grams added you will have a tuning frequency of 30 Hz and in room response into the mid 20's.

I have a JBL GTS-15 SUB in a box with 3.0 cu. in. (OEM 3.5) 10.5X25.5X19.5 air space. will two 12in passive radiators quiet the sub down and increase the low end (vibrates/unstable) Any reccommendatios or ideas appreciated. Should I go with a 18in PR?
I would not recommend adding a passive radiator or port of any kind to this enclosure. The recommended sealed volume is 5 cubic feet, the recommended passive or ported volume is almost 11 cubic feet. Adding a passive will not really benefit you at all here, probably only hurting more than helping. That woofer works very well in a sealed alignment so as long as it is getting clean power you shouldn't have any issues.

What is the limit for the added mass on this passive radiator?
We recommend no more than doubling the Mms on these passives.
