Dayton Audio SD270-PR 10" Passive Radiator
How many of these would i need to work with a sundown sd-2 8inch subwoofer with 14.5 mm of xmax One way. Also what size enclosure would you recommend and tuning weight?
I would recommend 0.6 cubic feet total, with two of the 10" passives. You will have to add 200 grams of weight to each for a tuning frequency of 40 Hz and an F3 of 34 Hz.

Hello, so I just recently heard of a passive radiator and was wondering if I can use it in my aplication. I have a 8" w7 in a sealed box that I wanted to use as a home teather subwoofer. Will it be worth cutting up my box? If so which size pr should I use
The W3 drivers are best suited in sealed enclosures. I you wanted to email tech support with the box volume you have, we can possibly run a model to see how a passive radiator might effect the performance. email@example.com

The two openings in the bottom of my Velodyne 810X measure 9" and 10". Will I need to increase the diameter to mount this replacement?
The overall frame diameter on this woofer is 10-5/8" so yes, the recessed opening will have to be enlarged to fit this.

i'm thinking of building a small 3-way speaker close to the design acoustics ps-10 but want to add a passive radiator to the design, would i get better bass response or would it be a wate of time?
This is entirely subjective and depends on the woofer you plan on using. Most 10" drivers will provide good enough bass response with a standard port, although others require a very small ported cabinet in which case only a passive will fit. The PS-10 speakers should be big enough for use with a standard port tube but again, this depends on which woofer you decide to use.

Would 2 of these be sufficient to pair with a JL 12W7? I'm looking at a 6 ft/3 enclosure, and 18hz tuning
I would not recommend two of these for that woofer. You will need something like the TC Sounds VMP 12" in order to handle the excursion.

Will these work as replacement Passive Radiator in the Optimus T-110 speaker tower?
Speaker size matches. I know I'll have to drill new mounting holes, as the original woofer had 4 holes, but hope that's all.
Yes these will work as replacements, you may have to play around with different weights added to the cone until you get the sound you want.
