Rangkaian Subwoofer 200 watt

type='html'>If we walk in the shop or mall and see the electronic equipment is high end, so sometimes we desire to have the equipment, for example, we see that a subwoofer bass sound is so excite. but for the price of our audio equipment may still include expensive

As an electrician we have any idea, how to make a quality subwoofer, such as not lose it in the store, but with an affordable cost.

Music of heave fluty, plus the subwoofer with the boom of the formations, it is that we want to show in this project. a series of simple and inexpensive numun able to meet the conditions above.

Active Subwoofer (rangkaian subwoofer) is a series of Simple and simple before trying this series to prepare yourself to listen to the crack formations that will be generated by this series. power amplifier for its series, please use the power that you like our previous post. However, to use the results of the maximal power with a higher power. for example, using the power that has STK4050 power 200 watt.

To suuplay series of the above you can use the IC regulator 7815 and 7915 or more can be seen here

Rangkaian Subwoofer Controller

type='html'>Subwoofer Controller

Subwoofer controller is quite simple, an input buffer provides phase switching and ensures that the input impedance of the source does not affect the filter performance, and this is nowfollowed by a 12dB/octave high pass filter. The phase reverse switch is used so that the sub can be properly phased to the rest of the system. If the mid-bass disappears as you advance the level of control, then the phase is wrong, so just switch to the opposite position.Contribute a better translation

The board has only one input, so if you plan to use a normal stereo feed supplying a single P48 board, you'll need to sum the two stereo outputs. This is easily accomplished by using a pair of resistors - the value should be between 2.2k and 4.7k. If this is done, replace R1 with either a 100 ohm resistor or a wire link.

VR1 is used to change the gain of the second integrator. The level through the controller can be set to make sure that there is no distortion - there can be a huge amount of gain at low frequencies, and if the gain is too high, distortion is assured!

The high-pass filter is designed as a peaking type, and gives a response that is almost perfect down to 20Hz. The lowest frequency can be tailored by changing C1, C2, C3 and C4. As shown, the response peaks at 18Hz, but you can use 68nF to increase this to 27Hz, or 47nF for 39Hz. See Table 1 for the full range of values.

The integrators (U2B and U2A) include shelving resistors (R8 and R11), and the capacitor / resistor networks (C3-R9, C4-R12) allow the HF attenuation to be halted at a specific frequency.


Important:


The unity gain frequency is important in only one respect - it will determine the internal gain of the system, and needs to be set based on the input signal level. If the unity gain frequency is set to (say) maximum (68Hz) and you have a 1V RMS input, then a 1V RMS input at 20Hz will severely clip the integrators. The setting for VR1 is determined by the input sensitivity of your power amplifier(s) used on the main system. It is probably easier to experiment a little than try to measure everything.

Rangkaian 11-90 hz Subwoofer Filter Using TL072 Op-Amp

The subwoofer filter circuit allows the addition of subwoofers to an existing full-range system, offering adjustable low-pass filtering with optional R6 and R8 boost and mono-summing.

The Subwoofer filter circuit to remove for separate pre amplifier to drive the low frequency sound a lot. In tone, call tone, normal Can not be done … is a fine deep low bass sounds like a bass drum, or at a movie complex in a low voice if we can be heard with But to add cabinets and amps. The subwoofer circuit is pass low frequency with in 11-90 Hz. Switching power supply 12V cut out if they need to use +-15V. I had change the Capacitor to cut out vocals per the red circle mark.

Ukuran Box Subwoofer 10"

This subwoofer box was created to match and aid the 1.618 Hi-Vi 3-way tower loudspeakers. The main focus of the HiVi 10" subwoofer was to reproduce ultra low frequencies that the 1.618 could not reproduce and aid in overall low end musical reproduction. Low, flat and not "boomy" was priority one. This subwoofer project uses the 10" subwoofer driver which can deliver plenty of bottom end.

The enclosure design and model frequency response are shown below.

Note:
  • 10" 4 ohm subwoofer
  • O-Audio 500 Watt plate amplifier
  • Freq Response: 25Hz up to chosen x-over point.
  • Overall Dimension: 21"x 12.75"x 20"
