Would this PR work with a titanic12, 250W amp and a 1.8 cu ft box?

Asked by: pepsi
This combination is not practical. Even with 500 grams of weight added to the passive, the tuning will still only be about 30 Hz. That woofer in the same volume sealed will reach lower than that, and save you $150 at the same time.

I am thinking of using this in place of a ported box to save space in a car audio install I plan to do with two of TC Sounds Epic 8" DVC subs, would this radiator be a good idea? I'm new to PR'S. Any tuning ideas around 1ft cubed internal? 

Asked by: WesA
This will work relatively well. I would recommend adding 500 grams to the PR which will provide a tuning frequency of about 33 Hz and an F3 of about 32 Hz. I also recommend relatively heavy fill.

I own a 2011 Mustang.  I am putting a phoenix gold elite 12D4 subwoofer (12 inch) in the trunk.  The sub is 1600 watts rms with 60 mm of excursion.  My trunk is too small for a vented box.  I would like to use a VMP 15 PR  in a sealed box.  Will this work

How much moving mass can be added to this passive radiator?

I've been tuning some boxes. I have a JL 12w6v2 and a TC Sounds Epic 12. I think for the money the TC was a better buy. However, the JL does sound really good. I'd like to pair it with this passive radiator. Based on my box size being able to add a substantial amount of mass (i.e. 1500 grams) would be nice. How much can this take?
Asked by: Absoluterock
It sounds like you are familiar with the formulas for determining mass. If not, or for others, many resources such as are available on the Web. The factory discusses moving mass as high as 2,000 grams and mentions that 1,500 grams resonates at 20 Hz under one example, so I would assume that 1,500 is acceptable. Remember, the benefits of mass are not "free." For a given bass signal, cone acceleration declines as mass increases. Thus you may lower the resonance with increased mass but the response time and therefore the phase of the radiator will also begin to decline and become a factor that eventually will be heard as muddiness.
