whats the frequency range theese are designed to play up to ?
fs says 17hz do you think they have a response up to 200 or 300 hz ?

id like to run a pair or 4 in infinate baffle / trunk baffle :)
also wondering if 600 rms is conservitave or if they can take a little more than that

plexlove
01-23-2014, 09:20 PM
Yeah they look identical to obsidian v2s except the motor is sloped on this one....id imagine they are pretty much the same sub...but idk about the specs...say vas 411.9 L??? lol dont know if ive seen a sub with those numbers...qts .38??? idk seems like these numbers dont make much sense, its like a high end sub except with some mistypes lol. Anyone ran these?

they are actually nothing like an obsidian. everything but the size of the cone and basket is different. the spiders. the surround. the coil. the motor. all are different.

So what about the surround? Isnt that the same one as obsidian too? And those numbers just dont make sense to me. 411.9vas? Is it a typo...dont know that ive ever seen a sub with vas that high

01-24-2014, 02:55 PM
no the surround and suspension is a much softer compliance

T3mpest
01-24-2014, 03:44 PM
These are fairly low inductance, very soft suspension 18s. They should sound worlds better than anything OA makes... They are noy really underrated, the soft suspension makes these very effecient... The coil can handle more thermally, but they will get low on low power.. 600 to 1000 watts is fine, just back of when you hear it soft bottom

I'll put this out there for you guys that are unaware

Sundown audio = Jacob Fuller
Stereo integrity = Nick Lemons
Obsidian audio = Jacob Fuller AND Nick Lemons

In no way am I saying these woofers are all the same.. obsidian, stereo integrity or sundown.. they are all tangled together by 2 well known and respected people

I suggest you ask them if any parts used are similar from either company

Would these be better than oa 18s also do you have any d4

2000LaDe
01-24-2014, 10:02 PM
all i have is d2's. on 600 rms yes these would be better. on more power would OA be better yes. Do these move more than an OA yes. Will these play lower than an OA yes. can you get an OA new for this price? no.

for whoever ended up purchacing theese i figure this link is good info on them if you wana do some homework
Data-Bass (http://www.data-bass.com/data?page=driver&id=46)

and
Data-Bass (http://www.data-bass.com/data?page=system&id=90)

after finding those links and reading up on them i decided to go with 4 also they should be pretty good ib capable on low power

On this link it says it is more suited for home audio, is there any reason for that? Will it be fine in my car?

brian84corvette
01-26-2014, 11:00 PM
what i got from those links is that this woofer has the ability to play down to 20hz with verry little distortion compaired to other drivers - and will still have a -3db response all the way up to 400 ish hz
so if you are one of the weirdos like me that set the subsonic filter in the 200ish range then this will play mid and sub bass maby mess with my 6ch eq a bit to blend the 2 together nicely but i see no reason at all this wont work fantastic in a car on "low power" up to 600w but could also probably be sound q oriented running on a old ab class amp bridged at 4 ohms on 300/400w

its not 100% nessary to run systems with 5 digit wattage numbers, extra batterys and alternators to satisfy the needs of bass in a viechle

Any idea if they get loud? My old system was a 12" Type R on 500 watts. If I put this thing on 600 watts will it be a lot louder? Or is it just SQ?

This question gets asked WAY TO MUCH!

In theory it should be louder BUT it will only be as loud as the box you build.
