After a visit to Fry's and their audio section, I realized that the Polk MM651 is very noticeably better than the DB651.

Hey Guys. I'm thinking of upgrading a little bit, but I can't decide between the two 6.5" coax speakers below. I'm hoping to put these all around.

I know that the Cl-6ex is supposed to be good, but the MM651 seems to have better response.

Have any of you heard both speakers, and if so, which would you choose?

CDT Audio CL-6EX:
http://www.amazon.com/gp/product/B001MSTA0A/
http://www.cdtaudio.com/series/coaxials/cl6ex.htm
Frequency response: 65-20,000Hz.


Polk Audio MM651:
http://www.amazon.com/dp/B001C3P6FI/
http://www.polkaudio.com/caraudio/mm/index.php?s=mm651
Frequency response: 40-25,000 Hz

Will be paired with:

Sony MEXBT3900U receiver:

I'm not going for anything too fancy, I just want a little better sound with AD2P and AUX in.

 

I can't comment on the speakers, directly, but I can tell you that a frequency response spec is virtually meaningless in this context. Sound-wise, sealing and deadening the doors should be the first step.


I'd suggest a better deck. Perhaps a lower line Alpine (102, 105) with their Power Pack. Good luck.

 

Agreed! I picked up some Dynamat Xtreme to line the doors.

 

Excellent. You only need about a square foot of material for the inside of the door and you can use the rest to seal the outer door skin. It's also a good idea to use some closed cell foam or Ensolite (ie. ~1/8" closed cell foam) to install between the door card and the skin. It'll do wonders to stop the panel from buzzing.

If you get a chance, read though this:
