opinions on cdt's ef 51 , ef61

Found what I beleive is a good deal on CDT Audio's EF-51 (5.25") and EF-61 (6.5") shallow mount separates, both of these are paired with DRT-25 PRO tweeters.  The local shop that sells CDTs does not have any EF's on hand, so a demo is not available.

I currently have Infinity Reference 5020CS mounted in the dash and I was planning to switch out the OEM 5.25" in the roll bar's sound pods for JL Audio VR650CXi 6.5" coax. I'm guessing that the CDT EF-51's would be an improvement over the Infinity's but what about compared to the JL Audio units?

Are they worth the $129.99 and $139.99 that they are going for?

TIA

Wow, I thought for sure that someone would using CDT Audio speakers would chime in!
