A line array speaker system is a type of loudspeaker system that consists of several identical speakers arranged in a vertical line. Line arrays are often used in large venues and outdoor events, where they can provide consistent sound coverage and high sound pressure levels over a wide area. Line arrays can also reduce feedback and unwanted reflections from walls and ceilings, improving the clarity and intelligibility of the sound.
Building your own line array speaker system can be a rewarding and challenging project, but it requires some planning, research, and technical skills. In this article, we will guide you through the basic steps of designing and constructing your own line array speaker system, using the example of a projeto line array 8 polegadas pdf download 1.
Step 1: Choose Your Speakers
The first step is to choose the speakers that you will use for your line array. You will need speakers that have the same frequency range, impedance, sensitivity, and power handling. You will also need to consider the size, shape, weight, and mounting options of the speakers. For our example, we will use eight 8-inch (20 cm) full-range speakers with a frequency range of 60 Hz to 18 kHz, an impedance of 8 ohms, a sensitivity of 94 dB/W/m, and a power handling of 100 W RMS each.
Step 2: Design Your Enclosure
The next step is to design the enclosure that will house your speakers. You will need to calculate the dimensions, volume, shape, and material of the enclosure. You will also need to decide how you will mount the speakers and how you will connect them to each other and to the amplifier. For our example, we will use a rectangular wooden enclosure with a height of 160 cm, a width of 30 cm, and a depth of 20 cm. The enclosure will have a volume of about 96 liters and will be divided into eight separate compartments for each speaker. The speakers will be mounted on the front panel of the enclosure with screws and washers. The speakers will be wired in parallel to achieve a total impedance of 1 ohm.
Step 3: Build Your Enclosure
The third step is to build your enclosure according to your design. You will need some tools and materials, such as wood, screws, glue, saw, drill, router, clamps, sandpaper, paint, etc. You will also need to follow some safety precautions, such as wearing protective gloves, goggles, and mask. For our example, we will use plywood as the material for the enclosure. We will cut the plywood into six pieces: one for the front panel (160 x 30 cm), one for the back panel (160 x 30 cm), two for the side panels (160 x 20 cm), and two for the top and bottom panels (30 x 20 cm). We will drill holes on the front panel for the speakers and on the back panel for the input terminal. We will use a router to create grooves on the side panels for the dividers. We will glue and screw the panels together to form a box. We will sand and paint the enclosure as desired.
Step 4: Install Your Speakers
The fourth step is to install your speakers into your enclosure. You will need some tools and materials, such as screws, washers, nuts, bolts, wire strippers, soldering iron, solder, etc. You will also need to follow some safety precautions,
such as unplugging your amplifier before connecting or disconnecting any wires. For our example,
we will use four-conductor speaker wire to connect each speaker to the input terminal on
the back panel of the enclosure. We will strip about half an inch (1.3 cm) of insulation from
each end of the wire and solder it to the positive (+) and negative (-) terminals of each speaker
and to the corresponding terminals on the input terminal. We will secure each speaker with
screws and washers on the front panel of the enclosure.
Step 5: Test Your Line Array
The final step is to test your line array speaker system. You will need an amplifier that can deliver enough power to drive aa16f39245
