because I'm tired of waiting for the 12" test session.. I'm gonna be doing some basic output testing at my buddies house..

I'll be doing power level frequency response testing on the termlab, using the SI mags, Mach 5 audio 12's. and a set of ultra cheap q power 12's..

we'll be using my standard daily design box (4.5 cuft, 33hz tuning) in my aveo.. with the 20.1 for power..

I'll be testing at power levels from 50 watts, up to whatever safe limit we find..

I'll be doing frequency tests from 20-100hz, at 5 cycle intervals..

I'll also have impedence graphs generated..

at the least... the testing will show everyone what a typical ported response looks like, and how emf and box design affects actual impedence... and we'll find out if a 12 dollar pair of woofers can do anything other than smoke //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

and I'm sure we'll shoot some videos too..

if anyone would like to see something specific.. let me know..

I'll have data graphed and posted sometime wed night..

Wednesday is pretty free for me...I'll bring my SQ demo stuff if you want, put those Mach5's through their paces //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Since there is going to be some educational value in this, I think it would be nice if you could do the frequency tests both in-car and out of car for atleast one of the pairs of subwoofers so that the novice's can get an actual idea of how the transfer function of a vehicle affects the response.

Not sure if that was part of the original plan or not....but there's my $.02 //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Can't wait to see the results.

****.. excellent idea...

you still looking for subs to blow up?
i think i got 3 12 inch MTX blue thunder old school in the attic for ya
I'd certainly kill em well during the main test session next month.. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

this is just a practice round

ool, use that dwele song again!! i would like to see how it scores and also how it sounds without the lawnmower background.

are you ever gonna test just 1 10 or 1 12?

 
I'll be doing some single sub testing for the challenge perhaps.. no 10's

10's are ghey //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Cool. Testing the BM's will have to wait until the official 12 inch subwoofer thrashing...I mean group test. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

 
if I turn them inside out on 'accident'.. are they covered under warranty //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Which amp and which speakers? What crossover are you using? You may be fine so long as you never push the volume too hard.
