I'm looking to replace my 12" Shiva X2 with 2 10s that can get at least as loud and sound good. They will be hooked up to a MB Quart ONX 1.1500d. So far I'm looking at the Dayton ho d4 and the IDQ d4 v.4. Would one of these be noticeably better than the other or is there another pair I should be looking at that will outdo either of these in sql? Budget is around $400 but less is preferable and used is fine.
