Need some input on subs...

Okay so right now I have two type R's in about 4ft^3 net @ 35-36hz....It's darn loud but I want something different...I know that I'll probably not get the same output from the subs I will be listing but that's fine with me...Okay so I need to know if anyone has experience with these subs or knows any other subs in or around the price range of $50-70 each with about 250-300RMS that sound good...I'm looking for more SQ than anything else...Here is what I ahve found thus far...
