JBL PRX400 Series Passive Speakers - Review

♪♫♪♫....[Music playing] We know there are a lot of speakers out there that are black boxes, about this size...and how do you tell the difference between a good speaker and a bad speaker? We're going to take a look at the PRX415 and the 412M to give you an example of what a good, non-powered loudspeaker is. And of course, now, there's a big difference between powered speakers and non-powered speakers. Powered speakers have the amplifiers inside, built in... Usually little alittle mixer associated with them. Non-powered speakers tend to be more robust, built for higher SPL and better performance, but the amplifier is not in the speaker. It's separated out. So these speakers go with Crown amplifers... and the Crown amplifiers have built-in settings that match these speakers so you get optimum sound. Let's take a look at the box itself.

First of all the PRX412M obviously is a 12-inch woofer, they've got a 16 gauge steel cover on it. Take a look at this... [Knocks on speaker]...Bam, Bam That is going to protect that speaker. You're not going to find that in a cheaper box-type speaker that has a really thin grill...so that's one of the things you're paying for with JBL. The other thing you can do with these speakers is you can hang them. You can see there's rigging hardware. This is M12 rigging hardware that's solid. You can hang this without worrying about a speaker falling apart or falling down. ...because inside the structure is designed by a structural engineer, to hold this box together from these points and there are about a dozen rigging points, three on the top, three on the bottom and there's on the side and on the back. So you can hang 'em uh, for use suspended from a ceiling, or from a wall bracket, anything like that and they will be great. So you're paying a little bit more for that kind of quality.

Of course the drivers inside are JBL drivers. These things are tested for 100 hours in a torture test. They will produce up to 135 Db SPL, when used with the subwoofer. So you're getting a high-powered speaker. You're getting linear frequency response, lots of transient impact. Let's take a look at the 15 over here. The 15 has a bigger faceplate. So that grill is even more important. See how solid that is. ...and then the handle... You can see that that's a nice beefy handle, ...on each side... ...got a nice recessed cup here... for the Neutrik Speakon connectors... Neutrik goes right in there and you can see how recessed it is so it'll protect that connector. ...so everything's very very solid. Again, more rigging points on the sides,

You've got it so you can have it slant for monitor use, as well as mains. Good solid PRX412 and 415 and then the 418 subwoofer and, if you want to, you can have this nice small pole and if you use the pole with the extension, the cup will tip, so if you have it high enough you can tip that speaker down and get into the coverage area without shooting over the tops of the heads of people when you're up on a stage. so it's got the tiltable, rotatable cup here. So the PRX412, 415, 418, solid JBL quality great sound and a super choice if you're looking for a non-powered speaker for either portable, mobile or suspended rigging use. ♪♫♪♫....[Music playing]
