How can I remove the thump from my loudspeaker?
Emily Dawson How can I remove the thump from my loudspeaker?
To remove the thump, the output signal must be delayed (and thus the transient) until the output voltage will reach a safe level for the speakers. In the circuit diagram, resistor R3 and capacitor C2 form an RC network timer. When voltage is applied to the circuit, R3 allows C2 to charge to about 1.2V.
Where can I find a speaker box template?
The template is included with the rest of the basic speaker information upon purchase. If the template can’t be found, contact the manufacturer for the information or measure the speaker yourself: Figure the depth (front-to-back dimension) of the speaker box by adding 2 inches (5 cm) to the depth of the speaker.
What kind of Screws do you need for a speaker box?
It is not necessary to countersink these screws. You should use a #6 1 1/4″ screw for the batten, which will allow the screw to go deep enough into the MDF without coming out the other side. Again, pre-drill the hole and use plenty of wood glue. How do you seal the box? This is an optional step.
Which is the best way to build a speaker box?
The basic two-speaker box designs are sealed and vented. This article details how to build a sealed speaker box, which separates the front and rear sound waves to improve the bass. Determine the size of the speaker box.

Why does my amplifier make a loud thump when I turn it off?
Some solid state power amplifiers make a loud thump when turned on or off. The thump you hear when you turn on or turn off your amplifier is caused by the sudden application or interruption in supply voltages to the amplifier output stages.
What kind of circuit is a thump eliminator?
The power supply circuit consists of a simple rectifier diode and a low value filter capacitor (D1 and C1). The ac voltage required is taken from the secondary winding of the transformer available in your amplifier.
