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

no the surround and suspension is a much softer compliance

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

How's the quality on these? Box size?

i mean im not familiar with them my self but it has my attention for the price. 600 rms 18 for $165 shipped? heck of a deal.

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
