    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?
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
