Obsidian Audio 15's?

35 posts in this topic

Posted (edited) · Report post

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 Obsidian’s share with the SA’s, 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.

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?
