Class A or AB amp for JBL S4700 speakers

I do now. Meaning, that they took a while to break in. Imo, they don't sound that good out of the box. They sound a bit dark, muddy, and closed-in.

The differences are the type of drivers used, the horn geometry, and the shape of the cabinets. As far as the differences in sound, I think these sound better than the Array 1400s, although quite a few would disagree with me on that. Also, these have better bass than the K2s. But the highs and mids of the K2 beat these. And of course the Everest beats all of them. I haven't heard the S3900, so I can't say. Some like them more than the S4700s, though.

The K2 is not complete. Because it has not enough gauge. You hear it back in the overall sound.

The new Wel Signature beats the Everest in timing and precision.

Bo, Wel Signature is a speaker cable. Everest and K2 are speakers!

Thank's dave72, that was very interesting, I would have never thought that, since I have not listened to these speaker's, I have listened to many, many JBL speaker's in my time, I even own a pair now, of course not to the level we are talking here, needless to say, with all that I have done, these are singing!, the s4700's look like the k2, you think?

No problem. It's the result of many hours of research and talking to people that know their stuff. Plus, auditioning the damn things more than once. Which I recommend that anyone does, including you. That's cool that your speakers are working for you.

Now, as far as the looks are concerned. A little bit, but not too much. The K2 has a curved cabinet and different tweeter and midrange horns.
