Dayton Audio SD315-PR 12" Passive Radiator
Will 2 PR's work with a JL Audio 13w1 (13.5")
I currently have a jl audio 13w1 (4ohm version) with 12mm xmax in a sealed 1.5cu enclosure (net and accounted for driver displacement etc) It is a 13.5inch woofer. Sd is 105sq inches vs. approx 12" sd's of around 80sq inches. Also running a great plate amp with 350w rms.It sounds good for music, but doesn't go low enough on movies. I've always liked the idea of trying a small PR design. IF I can squeeze (2) of these PR's into the current enclosure, does anyone see any problems in doing so? These are priced much lower than the other PR's on the site, and may be just shallow enough to do this.Just not sure if 2 of these can handle the sd of the 13.5" woofer, or if I'm going to have to put a ton of weight on them?thanks in advance.
I don't see any major problems with regards to this. You may have an issue at higher volume levels but two of these should compensate for the larger Sd of the JL. You can always use three PR's to be on the safe side although with just 12mm Xmax I don't see an issue.

What is the maximum mass you can add?
And what is the largest diameter of washers you can use and the maximum thickness of the stack of washers?
i dont have the dimensions for washers but if you look at it you should see if it fits. as far as weight goes i have a 454gram weight on mine and it seems like it could take more.

If you mount this passive radiator downfiring without any extra mass, does it sag out?
The Cms of the passive radiator is .45 mm/N. 1 Newton (N) is equal to the weight of a 1000g mass (1 kg) in earth's 9.8m/s^2 gravitational acceleration, so the actual force on the passive radiator when unloaded (200g Mms) is 0.20 N. Multiplying by the Cms, we get 0.09 mm of 'cone sag' when mounted in the down-firing position without any additional mass added. Does this calculation reflect reality? That is, when the passive radiator without any added mass is held in a downward-firing position, does it visibly sag more than 0.1 mm?
With no mass added, holding this radiator face-down, there is no visible sag at all.

should i get a pr or a another 12 inch sub
which is better i have 1 12 inch sub and i was told i should get a pr but i dont know anything about them what should i do
Passive radiators are NOT active speaker drivers, have no voice-coil. They are passive, meaning they will help move the air driven by another ACTIVE sub-woofer in the same [usually] non-ported cabinet.I prefer single sub in ported cabinet.

will 2 or 3 of these work with a 15?
I have a 15 inch sub with 12 mm of x-max and it's in a 2.5ft sealed box. Would this 15 be to much for these PRs? The way my box is, 2 or 3 of these PRs would be perfect. and plus, the other PRs cost to much money for me.
two would work fine,Sd 480 sq. cm. and Xmax 10 mm.
