Should a sax sound like a sax? Should you be able to hear the bassist's fingers dance down the neck of his Fender Precision? And what about hearing and feeling the impact of a rim shot? Hey, if hi-fi audio is your goal, you should be able to hear all of this stuff and more. The CDTAUDIO sound doesn't fatigue; there's just music-effortless, untiring, and above all, clear. The CL-609s have no annoying midbass boom like most stock speakers. And the bass was real, the treble crystalline, the sound transparent. This stuff is serious high fidelity. The CL-609 drivers are actually none other than the highly regarded CL separates, also from CDTAUDIO. The main difference between the coax and the separates is the 609's distinctive Tweeter. The installer takes the tiny ferrofluid cooled tweet and snaps it into a patented swivel mount on the front of the grill. With this cool setup, you can install the CDTAUDIO like a drop-in coax and still aim the Tweeter like you would in an expensive custom install.  Slick, huh?

But this speaker is about music, not gimmicks. We're talkin' sweet sax, accurate bass, and real piano. Ya know, a good acoustic piano sound is a tough goal to achieve for the audiophile; the piano is difficult to record and even more difficult to play back. And yet, from Elton John to the classical stuff, the CL-609 allows a piano to sound like a piano. And we believe that's the way it should be.
