Sub for metal dual or single?
 

Hi I'm gonna get a new sub setup this year.
I'm listening mainly to Metal/Punk Rock/Death metal and a bit of Dr. D.R.E., Snoop, Cypress.

My amp drive 460rms 2ohm/360rms 4ohm
Should I got for 2 10" sub (~250rms each) in a sealed box
Polk_Audio_db1040

or for a single Alpine SWR-1042D or SoundStream XPRO10 in a sealed box?

I have a 12" svc 4ohm in a ported box and I'm not happy with that.
I'm looking for a thigh punchy bass, I prefer sq than bass power.

I have two 12" subs in a sealed box and I find them to be quite punchy for Metal/Rock/Punk/Industrial etc.
