[QUOTE="Langston Holland, post: 55495, member: 171"] Re: The top ten The dipole arrangement of the KF730 is what enables it to hold its horizontal pattern control at least a half decade lower in frequency than competing designs. A box/horn of this size is physically unable to provide directivity to wavelengths longer than about 1kHz, but the dipole woofer arrangement makes this possible - though as always - at a price. But the price paid is low compared to the benefit of LF pattern control. The happy result is the quietest stage with the lowest potential for feedback at a given audience SPL of any line array box I've ever experienced whether it's ground stacked or flown. I sound like a pimp! :) The sad result is that it gives up a bit of potential forward output and it has a rear lobe from its figure-8 pattern that will be a bit louder than a standard design which directs much of this energy to its sides - such as where the musicians are. A cardioid LF design such as on some of the NEXO boxes would be ideal, but there are downsides to this as well, such as cost, weight and size of both the boxes and amp racks. But if the physical and monetary budgets permit, this seems like the better solution. Here is a killer bar rig that a singer with a Beta 87A or the like can stand near at full tilt levels: [ATTACH=CONFIG]150446.vB5-legacyid=3909[/ATTACH] This is a regular symphony gig I do using (6) overhead Neumann KM184's and an overhead Shure VP88. KF730's are run full range. No subs, but amazingly the VLF of the timpani carries nicely. I am about 15dB below the threshold of feedback at proper audience levels.
