Today, I received my beloved new components: CDT EF-51 with the upgraded DRT-26 aluminum tweeter. Bought them from djdilliodon (Island Sound in NYC) for $245 shipped to Canada! Shipping was quick (one week), and the components are amazing! Quite an upgrade over the MB Quart Discus (DSF-213) I was using, an incredible jump in clarity and definition. I've been hearing things in my music I'd never heard before, in just about an hour's worth of listening!
FYI, rest of my setup is a JVC KD-AR5500 HU (don't like JVC much, but wanted something that perfectly matched the interior of my BMW 328is), MTX Thunder564 amp and Pioneer TS-W256C sub.
This is my second set of CDT comps (I had CL-61a in my Integra) and I've never been disappointed. These EF-51 with the upgraded tweets blow away anything I've ever heard!
All in all, the speakers are terrific, and buying from Don was a great experience. He's very knowledgeable about his products and will take time to share his wisdom with you. I highly recommend him and CDT products as well. Thanks Don!
