Spin Your Sound Right Round with LD Systems ICOA:

The outstanding bass reproduction from the horn-loaded woofer makes the LD ICOA 12 A the ideal choice for musicians, bands, entertainers and dance schools. It also allows DJs to play sets without the need for a subwoofer. Deployed vertically, the speaker impresses as a satellite; horizontally, it's excellent in suspended systems or as a floor monitor. The efficient class-D power amplifier delivers 126 dB max. SPL and 300 W RMS performance.

Drawing on DynX DSP technology by LD Systems, the speaker delivers perfect performance with maximum clarity and power under all conditions. 4 presets, a 3-band EQ and a delay function facilitate optimal adjustment of the sound to the venue conditions. The 2 line/mic input channels with individual gain controllers, plus mono mix output, allow a variety of signal sources to be connected.

Thanks to its shock-resistant front grille and ideal 55 degrees tilt angle, the LD ICOA 12 A is also outstanding as a floor monitor. Placed vertically, the 36 mm dual tilt read more stand attachment offers the choice of a 0 degrees or 5 degrees tilt angle for optimally adapting the system to the local acoustic environment. Extensive and smart accessories for installation and transport are optionally available. 4 aluminium handles with an ergonomic rubber surface provide optimal grip when carrying the speaker.

I was stuck between these and a few other brands for monitors.. after watching a video on a speaker tear down of each company, it was clear this was the way I was going to go.. the build of these and the components used surpass the other speakers in this range. These are built like tanks and have had nothing but compliments on how they sound.. the only thing I wish they did have was a visual clip light that I could see from a distance..
