The Great 15" Challenge

I'm not in this for any good concrete info. Obviously the results can never be duplicated, and aren't anything to decide a purchase on. I'm in it for 1 reason. =)

Which is.... //content.invisioncic.com/y282845/emoticons/greedy.gif.5a53e6246569d7ab79867170f3b06629.gif:greedy://content.invisioncic.com/y282845/emoticons/greedy.gif.5a53e6246569d7ab79867170f3b06629.gif

Hahaha PM me and find out.

I would be asking for the sky here, but it would benefit many if impedance curves of each driver were performed while they are in the box. This of course would be done prior to the 'test'.

Well now, this testing methodology is becoming a little more credible... //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

You know, I'd tell you to haul your sorry *** up here for some real testing but getting all those drivers across the border may be an issue //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Companies in:

DC Sound Labs

Sundown

RD

Cascade Designs

Evo

Not all companies are sure yet on which subs they will have sent in for testing yet. I would still like to get a hold of Nick at IA but have no idea how to reach him.

Other subs being used:

DD 9515G

AQ HCD3 Aluminum

Orion H2 Possibly

Audiopulse Revo Possibly

EVO is a new company just starting up that was started by Ssackett.

Hey Mike, if you need help building PM me. I can't guarantee i'll be much help but I'd like to check this out

Will an accurate clamp meter be used to measure actual power during each test? Will each sub only be given it's rms rated power? How will the gains be set during these tests?

Dual 2ohm models only ?

My buddy is letting me use his Fluke clamp, i know its not the most accurate equipment in the world but I figured it will work. Subs will be put in classes based on their RMS and will be tested from there.

Dual 2ohm models only ?

Correct as I want all the tests being conducted at 1ohm and 4ohm from my big amps

Too bad I live so far away, I'd like to see some of the testing.

However, the only real person benefitting from this is the owner of the test vehicle. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Great 8" challenge was fun, great 12" challenege was eh at best (and has subsequently been erased from everyone's minds), great 15" challenge just seems like a lot of work for inconsequential results.

Good luck to you anyways.

Im getting 6 boxes made, spending at least a week straight on testing, and I will be returning most all of the subs, how am I benefiting other then seeing results?

Seeing as how almost all of these subs did not get to participate in either of the last two challenges I think these results will be beneficial to these companies, specially cause almost all of them are new to the market and 09 models.

Whatever happened to the great 8 challenge. Was wanting to look at it
