subwoofer amp

Hi, Attached is a class D amplifier for car use I found on the net. The circuit looks very compact and I would like to build it just for fun and get to learn class D. The amp directly converts the battery voltage into amplified audio using an inverter kind of mechanism, I know its not a perfect...

Hey everyone, I’ve been seeing that while most people go with active subs these days, there are still quite a few who stick with passive subwoofers. I’m really curious to learn from those of you who use them. A few things I’d love to hear about: Why passive? What made you choose a passive sub...

I’ve been doing some reading here and on other forums about subwoofers and subwoofer amplifiers. It’s clear that measured performance — things like frequency response, THD, output levels — tells part of the story. But I’m curious about how people actually use them in their daily setups, and...

Bought 2 svs 1000 pro and after 1 day they are both exhibiting different levels of coil whine, at night with them both whirring away I can hear them at mlp 7/8 ft away in the quieter scenes, my sb 3000 had coil whine that could only be heard from about 5 inches away. What's an acceptable amount...

Hello Guys, I’m looking to experiment with a 3D-printed 3-inch subwoofer and need a small, suitable amplifier for it. The subwoofer has a 4 Ohm impedance, with 15W RMS and 30W peak power. Tang Bang W3-1876S I’ve already connected a pair of Swissonic A305 active monitors via RCA (Chinch) from...
