help for new speakers selection!

[DiegoEjea]

Hello all!

I´m spanish, excuse me for my english!
I´m looking for a very good quality 6´5´´ coaxial speakers, but i need some opinions because i can´t listen to them after buying. Now i have a pair of 3way kevlar PIONEER (european model), within 1´25´´ magnesium mid-tweeter and a 0´4´´ tweeter. They sound good because i made a LP filter for the woofer, but the mid-tweeter has louder resonances at higher levels. Now i want replace this speakers for another with better SQ than these.

I want very impulsive bass and midbass and very clear sound at all frequencies.
What do you think about these:

**Polkaudio MMC 650 (I´m curious in this speaker, and i can´t listen to it in spain, so i need opinions)

What about the bass? Better than Rockford speakers?
Thank you very much for your time! I´ll be helpful with any opinion!!

Im thinking this is for a car application?? I would check out DynAudio.. They make excellent drivers with great bass (for a mid/woofer) and IMO an unsurpassed SQ for the price. I run 4 6.5" mid/woofer's (actually they are in centimeters, so what ever that is, in my vehicle. I also use DynAudio tweeters. I dont recommend using coaxial speakers. IMO you would be much more satisfied with seperates.

Have a good 1!
