Array Speaker Cabinets

The QSC KLA 12 cost over 2500 dollars and is worth every single penny of that price! It is a 1,000 watt active speaker with a 1.75 inch high frequency driver and a 12 inch low frequency driver. It has adjustable frequency optimization features and a very good sound. It has a 12 to 1 ratio factor that will allow you to have up to 5 separate units. I have only had the chance to personally work with it 4 times now but each time that I do I love it. I would purchase it myself If I had the need for it. There is a tilt direct mount on it that makes it easy to get it in the perfect position for any room or set up. With the 500 watt by 500 watt power module, the sound you will hear with this speaker will be big and warm. The highs are clean and the mids sound just like they should. The lows are very clean and full, the frequency range is 44 Hz to 20 kHz. This bi amped speaker is powered and it has 1 XLR input and 1 XLR output. Moving this speaker from place to place doesn’t seem like it would be too difficult though I have not had to move it myself before though. It only weighs 55 pounds and stands about 15 inches tall, and 23 inches wide. These boxes sound great and if your budget can afford to get them I highly suggest doing so, you will not be disappointed. The space that I heard this speaker in was big enough to seat between 300 and 450 people. The sound was huge and had very good stereo imaging giving a wide and big feel to it. I heard live music coming through this speaker a few times and I can say that anyone could use a speaker like this in their live rig. Question is can they afford it, because quality like this doesn’t come cheap.

The Mackie HAD is a 12 inch 2 way powered speaker that delivers 600 watts of power and has some onboard limiting. These speakers are pretty portable and easy to move around. It has 1 XLR input and dual compression drivers (1.7”). This speaker is made for live applications and not studio use, using it in the studio will not give you the sound you expect it to have because I have tried it in a studio twice and was not pleased with it. But live it has a very nice sound; it is pretty big if you keep it in a smaller venue. In a medium to larger size club it will have too much space for it to cover and it just is not powerful enough to handle it. The total weight of it is about 60 pounds which makes it very portable, but for that much weight and at this price you would expect to get a bigger sound or more watts. That is the only downside of this speaker. Everything is great with it except the overall power which for me was probably the most important aspect. I do recommend this speaker if you tend to only be around smaller venues. But if not; it really isn’t worth getting this because in a bigger space it will have no value to you anymore. The crossover frequency is 2Hz and the range is 57Hz to 20 kHz but there just isn’t enough power behind it. The overall sound is clean when in a smaller space, the bass is not as expressive as I would have liked it to be but depending on which style of music you are working with it could be just fine the way it is. If your music tends to have a little more thump to it, then I do not recommend the HAD because there isn’t enough low end to give you the sound you might be looking for.

R4/R8 is specially designed for luxury cinema, large-sized meeting room, multi-functional hall, church and auditorium applications. The system consists of 1 active subwoofer and 4 full range speakers which can form multi-cluster configurations. R8/R4 is designed by applying the line array concept. It features compact dimensions and an easy to handle design. The built-in 600W amplifier and DSP make it available for use at any moment when connected to sound resource. System control over each cluster at frequency response, crossover point & slope, delay, gain and limit protection can be achieved by connecting the speaker system to PC via USB or RS232 port. Adoption of ribbon tweeters offers a wide-range frequency response to up to 40KHz. The tweeter's impedance and phase response curves are nearly ideal horizontal lines. The light moving mass of milligrams ensures excellent impulse response. Utilization of the unique thin foam surround and specially coated cone paper has reduced the distortion rate effectively. The active subwoofer applies Low Distortion, Linear Amplification, and DSP technologies. Input signals are amplified by the built-in pre-amplifier, then processed and distributed by DSP, finally output via power amplifier to the subwoofer and the full-range speakers, which forms an integrated system. The flying hardware is designed to fit different application situation flexibly with the splay angel adjustable by 1° increment vertically.
