Does any one have any info for this Precision Power sub?

Specifically dimensions, power handling, and recommended enclosure sizes

I can't find jack using google and DEI/PPI web site is crap
A downloadable manual would be perfect

you're right, info is pretty damn hard to find. and for the record i'm glad someone else agrees with me about how horrible DEI's product website is.

Directechs is decent, but trying to find any info on their normal site is worthless.

Alma Gates ran those in her first world record breaking ford bronco.

If I remember right .75 cf sealed for a 10 and 500 watts RMS,



A damn good sub, A DAMN GOOD SUB...........!!

Thanks for the useful info GSteg

Linear Excursion ------------ ±5.5mm ??????

Kinda on the low side-- Ported may be better for this sub if you really want some output--

It's on the low side, but the sub did come out in the 90s where most subs were barely surfacing 10mm Definitely not up to today's standard, but hey, thats why we're fortunately that many new things are coming out

Nice sig --

The reason I'm recommending to go ported-- a 10 sub as tight as these are would most likely play really well ported and still sound nice and tight--

Plus you'll have a huge gain in cone control around the tuning freq--

Simply plotting the sub's specs in a program like unibox or winisd will show you where the xmax approaches max spec in various enclosure types vs. the amount of power your amp will actually be able to feed it (a little testing could determine these actual figures also) --

Ported will smooth that curve way down in the low freq's and you can just run a subsonic filter to protect it from overexcursion below the optimal operating freq's --

Pretty easy to model and determine-- and ported will definitely help that 10 get a little louder-- This config will help utilize the subs power handling capabilities as it's got a 3" coil that will undoubtedly have increased thermal power handling--

I have to agree-- those subs come from the day and time when PPI owned the competition-

You happen to be on ECA or some of the larger Car audio forums? I've been out of the audio loop for a year now. I recently downgraded my system too.

Naaah-- I try not to spend too much time staring at a computer screen-- It'll burn your eyeballs out--
