2 Soundqubed HDS312, 2 RE SR pro 12s, or 2 RE SRX 12

If you plan on running two subs and not upgrading you amp I would say the hds2's because your amp will push those better than the hds3's. And RE audio is'nt really recommended on this forum.

Well, the main difference is that the sq 12's are 1200wrms, sr pro 320wrms, srx 300wrms. If you are limited to these choices due to budget, What I would do is; The sr pro's in dual 2ohm, so that amp will see a final 2ohm load. If I recall, those will need a good bit of space. If you haven't made your purchase yet, I would get one sq hds312, dual 2ohm, so it can be ran at 1ohm. You also may want to check the classifieds on here, there are often times when you can find good deals on slightly used, but much loved gear. Just remember, what ever set up you choose, the enclosure will be about the most important part of any particular subs output. Good luck, and welcome.

re has went down in quality... id go AQ !!! (soundqubed)

I'd second Slobalt. Everybody says RE isn't what it used to be, I was looking at RE before I bought my HDS210s. I love my Soundqubed subs. If you plan on upgrading your amp later then get the HDS312s, if not get the HDS212s. Build a proper box for them and you'll be happy

Or another way to go is 1 HDS315. It would slam too.

Good choice but the hds312 are out of stock. I'm waiting on them myself
