thinking of selling my 2 15" RE sx's locally and changing it up ( rather get D4 15's then upgrade my amp to a .5 ohm or another 2k+ Rms amp ) anywho,

basically would an obsidian 15" Handle my Hifonics BRZ 2400.1D, i hear there 600rms subs, so id have to buy D2 ( again.. ) and run them at 2 ohms for 1700rms.. should work hey?

EDIT: what would be the most you'd put to them or SA-15's daily.

I've posted this a few times on other forums but I suppose it doesn't hurt to outline the differences between the drivers again.

There are a few items that the Obsidianís share with the SAís, but a short list of what is different between the two drivers is as follows:

Surround material
Surround shape
Cone thickness
Basket type
Top plate OD
Top plate ID
Top plate thickness
Magnet grade
Magnet OD
Magnet ID
Magnet thickness
Backplate OD
Backplate ID
Backplate thickness
Backplate machining
Pole ID
Pole height
VC cooling method
VC winding width (winding height)
VC OD (both D2 and D4 are different from the SA)
VC former vents
Enclosure requirements
Thermal power handling (SA has the advantage)
On the TL the SA's are between 0.5 dB and 1 dB louder
F3 in specified enclosure sizes and types (OA's play a smidge lower - in Klippel testing the Fs on the Obsidian's is a little lower and Cms is slightly higher, which is indicative of more LFE with all other factors remaining the same)

Both drivers do use a Nomex spider, flat sewn-on leads, and a triple joint reinforcement advantage.

Power handling is not a power requirement! Don't install suckage!
Simon Eichenberger is the man.

So there isn't THAT much different between the two, right? Lol JK... Do yall have plans to release other lines of subwoofers, or will y'all be sticking with only the current lineup?
Bassless once again. Can't seem to keep a system for more than a few weeks :) Saving for a '06 Nissan 350z, look for build around June 2012.

i just got mine in the mail tuesday or wednesday and i got my box made it is 3.3cubes to 35hz and it pounds iv only had it hooked up for like 2 days total and have it only 600w rms mtx amp and so far my 1 15 wrecks my buddys 4 12's but he is also running boss audio :rofl: but i guarantee you would be happy with 2 15's mines the d4 ran to 2ohm. and i know it this sounds bad but this is my first loud system and i almost want to get rid of it already, i have a headache cause all i did today was roll around with it on bumpin decaf 8)

Edited by Hertz_dont_it, 23 July 2011 - 11:58 PM.

Current system: Front stage: Alpine type s 6.5 No rear:Alpine type s 6.5 headunit: alpine Amp: Jbl bp600.1

Sub: Alpine type x 12  

 

dont know much about them. Found a "FLUX" Capacitor on ebay. If I add this to my system, can I really travel into the future? And how far into the future? That probably all depends on how I ground it though, right?

Dude dont even waste your money on capacitors get a second car battery preferably a kinetik or stinger or any other car audio battery use the battery that is correct for your systems true rms wattage do some research on the net for this. Go to kinetiks website they explain how to pick a battery from thier site that fits your system. :shrug:

I know people have already told you this.

No one can tell you if it will be louder. There are too many variables.

I hate People with crappy primered cars rolling on hubcaps that are louder then me.

imo it would be hard to beat 4 12's with one 15 bc of the massive amount of cone area the 4 12's would have over the 15 not that it couldn't happen but if both are set up right it would be hard :shrug:

Ok. Build your 4 12 box out of particle board with uneven cuts, not sealed up, tuned to 17hz. Then build the 15 box out of 3" bamboo, perfect cuts, tuned to 35hz. See which one is loudest at 43hz. :)
