JBL Pro 4408A : moosers's user review
The JBL Pro 4408As are a set of passive studio monitors that I've used in a radio broadcast control room. I haven't used these in a traditional recording studio setting, which is where I'm generally used to working. They can however be used in a variety of settings without a doubt. I don't know what kind of power amplifier was being used with these when I was listening on them, but it will indeed require an external power amplifier since they are passive monitors.
I was definitely impressed with the sound of the JBL Pro 4408As. While I didn't use them for critical listening or mixing, right off the bat I could tell that they had a full sound. We were using them for listening to the radio broadcast that included both music and speech. It was absolutely a pleasant listening experience as I could hear the full range of frequencies well, including a good amount of low end. Judging from doing simple listening on them, I'd definitely say that they'd be suitable for use as near field monitors in a recording studio, but I can't say how well they would work for mixing or other applications where you would need to do more critical listening that what I was doing.
I haven't seen the JBL Pro 4408As in any professional recording studios, but I'm sure that some studios out there do have them since they have a great sound and are designed for both use in recording and broadcast studios. The price is about right for a nice sounding set of monitors like this, but again since I haven't used these during critical listening situations I can't say how they would compare to other studio monitors in this price range. JBL has a great reputation for making high quality studio monitors, so in no way was I surprised by the great sound that the 4408As have. I'd recommend jotting these down on your list of mid range priced studio monitors if you're in the market for some.
