2 Type R 12s or 1 12 type X

I am considering these two alpine subs and I was wondering what would give me the loudest and clearest sound. Soundstream Rubicon 1000x1 @ 1 or 2 ohm

i would run this at 1 ohm if you get the dvc 4+4 ohm wire them in parellel you will get 1 ohm

raw volume 2 type R's ported. Type X drops really low but it is power hungry

2 type r's would be your best bet. X takes extreme power. I mean ALOT."I don't play games. I play Nakamichi and that for real yo" - Probably some japanese kid said this in the early 80's trying to sell stereo out of his trunk lol.

I already did the comparison between 2 r-12's, and 1 x-12 , , , im going to stick with the 2 R-12's because they can get alot louder because of the difference in air movement.  But i did really like the X for its ability to shake the hell outa everything under 40hz.  Altho, some bass loveing people dislike the X because it plays the bass the way it should be.  It has a nice smooth role off in the 50hz and upper frequencies, , , most other subs just blast those frequencies off at full volume.2003 Chevy Avalanche,Eclipse CD7000,Morel Elate 5,Adire Extremis,Alpine PDX-4.150, 15" TC-3000, 2 Alpine PDX-1.1000, 470Amp HO Alt.

Same here, In comparison..If you have 2000-3000 watts to give yea go with the type X      but if not then go with the 2 type R's2009 0-1000 Trunk WR 154.0DB 2009 1001+ Trunk WR
