    As the title says, has anyone heard the JBL S3900?

    I'm really curious about these speakers, but the only way I can hear them is to purchase them...no dealer around has them and will only bring them in on purchase.

    I have the JBL 4306 and a set of Altec 19s. I love the JBL/Altec sound so I'm betting I'd like the S3900, but that's a pretty big gamble on a speaker I've never heard.

    I have heard one of the larger S4700 with the 15 inch woofer a couple years ago with the same tweeter and midrange drivers. Like all JBL's they tend to be a little to forward and bright for me. Altec model 19 and I get along pretty well, but I don't like ported bass all that much and that goes for JBL, too. As I remember the Altec is a 6 db more efficient than the JBL 3900. But the JBL with two woofers will handle more power than the Altec with significantly lower bass distortion. You may think the JBL is to dry until you get used to listening to bass with a magnitude or so less harmonic distortion than the Altec. . My hearing fails above 17 KHZ so the super tweeter doesn't show me that much . Some times I think I hear the super tweeter influence, but then I can't really say I can. I will say I much prefer the HF's of Magico, Snell and a few other speakers, but that's another totally different design and cost issue. When I choose speakers I am all about the bass below 250 hz, but if the HF's are irritating I don't care how good the bass is. I will say I have always been fond of the JBL 4435 two way speaker. Its kind of old school and the bass isn't always to my liking, but that said if I had to own a pair of JBL they would be my first choice. A Paragon with modern drivers my second with Altec 950 UHF ring radiators. They were smooth.

    Grizz. I have a pair of 4429s. They are pretty mellow speakers on the upper end. A lot of detail also. Looks like the uppers on the S3900 are pretty close. I can compare them with my other system which have a pair of LSR6332s. Very close in sound. The newer JBLs do not have a "horn sound", they are pretty doggone flat. The LSR series were in the Pro. line, so intended for monitor use. Check the specs on the 6332s. Look at the distortion at 93 and 112dB. I don't know if the S3900s are spec'd at those levels for distortion. In my opinion the newer JBLs are very good speakers.

    Selling off some of my other speakers and decided to give the S3900 a try. We'll see how they are!

    So I've had the S3900s for a few weeks now. They are absolutely fantastic. I'm using them for both music and movies, so they're being driven by a Quad Artera stereo amp and a Marantz 6011 as the pre/pro.

    They aren't what most people associate with horns (bright, harsh, etc.), and are not bright at all. They are extremely smooth and yet still retain the dynamics and fast transients you expect from horns. I look forward to listening to them every day and couldn't be happier with them.

    I kind of figured you would be happy with the sound. I bought my 4429s unheard, and am still very happy with the sound. Also use them for home theater. No center channel required! Oh, and it took about a year to break the suspension in on the 4429s. The bass goes well into the 30s after the break in.

    FWIW - I didn't care much for the JBL S4700 I demoed several years ago.

    Will we be having a shoot out between the 3900’s and model 19’s?
