its ok, just playin' witcha peter dont get hard.

just cuz they can put up nice numbers at low frequencies doesnt mean anything //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Well without getting too scientific it is generally accepted that; the more sensitive a speaker is the louder said speaker will get ( in dBs ) under particular measurement conditions ( 1w/1m ) at a certain frequency or frequencies..A sub with a 1w/1m volume of 103db will get louder -- powered by 1 watt, listened to from 1 meter away -- than a sub with a 1w/1m volume of 83...
It is directly linear dude, a sub with a rating of 103 vs a sub rated @ 83 ( sure on a set freq ) will get much much louder on the same power..On whatever frequency.

Not true and not true. That number is generally NOT measured but extrapolated (estimated) in TS calculations and as Jacob said the freq in question is generally well outside of the "subwoofer" range. That spec is good in selecting an 8" full range or PA driver but not so much with subwoofer.

To make a more "sensitive" or efficient motor typically you do more magnetic flux in the gap (tighter gap, stronger magnet, more coil in the gap) or lighter moving parts. To some degree a very stiff suspension will also take down your efficiency.

I have some woofers that spec out with a very high sensitivity that don't get as loud below 40hz as stuff with 10db less "sensitivity". For purposes of a car audio subwoofers it's a bullshit spec

That "efficiency" topic has been discussed at length in relation to subwoofers.

Why does any company list the sensitivity? Marketing? I see a lot of the "if ya can't beat em join em" type mentality when it comes to marketing car audio and the **** teenagers (the prime demographic) will buy into.
And why is higher sensitivity inherent on larger subs?

/e I've read that law before, good read, but hard to keep track of all the tech stuff in my head .

If you have woofer tester software and run TS parameters it's one of the things that they all throw at you. Not like they actually sit around and measure, they just plug the woofer into the tester and copy/paste the specs it throws out..

Hoffman's law is easy

You can have ONLY two from this list:

1. Small box

2. High efficiency

3. Good low end extension

Some do, but many take it very literally and think they can put that much power on a 2.5" coil.

I didn't realize they were 2.5" VC. It doesn't make mention of it anywhere on the site of that.

Didn't read all of this thread;

Skars have been selling well and received many compliments. No sub is a "do all, end all", but the VVX performs well in its niche. There should be a good showing of them at SBN, IIRC.

Best wishes to all!

And Jacob, if you want a challenge, PM me //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Troof. Everyones basing there answers on specs and opinions

I call your bluff, sir. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Uh yes it is true. The higher sensitivity the louder the speaker gets off the same power as a lower sensitivity sub, on whatever frequency it's tested on...That's the generally accepted definition of sensitivity..Calling me wrong means nothing I just directly copy and pasted my info from car audio sites lol.

If it doesn't mean **** on subs then why is it even listed?

Yea it's been discussed at length, I've read the discussions, and sensitivity means the speaker's volume at 1w/1m on a frequency...That's....what....it...means...lol if it doesn't work ~50hz than that's what you say, not "not true, not true" because it is true...

lol ok let me fix what i said. almost everyone...

looks better than the skar Subsonic

I know there was a ton of bad blood from folks toward the owner of SKAR subs but,I didnt hear any bad reviews of them.Seems like they came in like a bat out of hell and then totally disappeared.They are not on ebay anymore either.Was just curious....

Dis is true... gunna be another peak in in sales once your build is done Im sure
