    Circuit Filter Pcb
AI Thread Summary
A user is building a custom audio setup using old tape recorders and amplifiers, seeking a filter circuit to combine left and right audio inputs into a single bass output for a subwoofer. They have two tweeters and two speakers but only one subwoofer. The discussion includes a mention of crossover circuits, which direct high frequencies to tweeters and low frequencies to subwoofers. The user has an amplifier for the subwoofer but is looking for specific circuit designs. Assistance with the circuit layout is requested to complete the project.

hi every one
i happened to have some junk tape recorders and amplifiers
so i set about making myself a deck with a cd drive
i have two tweeters two speakers but one sub woofer
i want a filter circuit so that i can take the left right inputs and get one bass input for the subwoofer.
and iwant to make the circuit myself.so if anyone can help tell me
thanks to the helper in advance.:smile:
 
Engineering news on Phys.org
Here are some common "crossover" circuits. A crossover is a device which sends high frequencies to a tweeter, and lows to a subwoofer.

Note that you will probably have to further amplify the signal to your subwoofer.

i do have an amplifier for the sub but where are the circuits?
 
Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
