Whether this is really so was (the Platzverhälnisse in some studios put the close) I doubt it. Sure, they were also used for control purposes again, because what good is a bombastic sound from the PA or on the high-end headphones, if the target group has only a few simple shelf speakers?
At least you can see on many photos a few of these boxes on the mixer console are; o)
In any case, the JBL Control One are among the good representatives of the genus "bookshelf speaker". By design, they do not have to bang a 120 liters more way bass reflex box, but what is being produced with a few adjacent watts of sound even in low frequency range, enough for the home and party use of completely. Therefore, I have after my first couple to "divorce victim" was resorted to the original again after many years and was not disappointed, but now with the usual "sound" (linear is different) rewarded.
New are the accompanying wall brackets, for which there is a thread in the housing. This is very handy if you have ever tried to mount on normal boxing a venal wall mount. Most is a bass reflex port, the connection panel or something else to actually optimum position so that the bracket then usually somewhere must be screwed and the box is equal to or increasingly wrong.
Tricky on the wall bracket but is the guide and the enclosed steel rod. If you follow the instructions and pulls the cap nut with the steel bar, this inevitably leads to failure, since not only the mother is not carried out massive but hollow and, secondly, the embedded brass sleeves weaken the mother also. So no, never, under any circumstances, the steel rod used to wear! Hand tighten fully sufficient! If one then thinks "But there is still play there," then look closely: this game is in the transition of the ball joint to the thread and can not be eliminated! Nevertheless, the box is thus firmly aligned.
If you still end up with a broken Überwufmutter, then just at the hardware store a hose clamp for 40-60mm diameter procure and tighten them to the union nut (see customer images) until the nut breakage closed, no further! This means that the mother can once again loosely tighten by hand and fix the box. So Do not overtighten the hose clamp itself until it's double trouble (this would be the mother hollow grind), but only to bring the mother back in shape and thus stabilize. Individual JBL Wall Mounts costs nearly 25 euros each!
