    Music System Frequency Response

    Although I am not an audiophile, I am a critical listener and I can tell when the sound quality is not up to the mark. While I like my current 5.1 music system setup, I still feel like it could do better. I spend about 70% of the time listening to music and about 30% of the time watching movies, or TV shows or live TV. So a major part of my listening is music. Generally I like a very flat response from my speakers. I don’t like overly bright sound in general. A slightly warm sound is acceptable, but prefer the frequency response to be flat so I can listen to music as the original author intended it. So I decided to check the frequency response of my speakers.

    Building a DIY 5.1 Audio Video Receiver – Part 6

    In the last post I mentioned that I was looking for a crossover board. The one that I purchased is putting out a huge DC bias and I was not comfortable using it on my sub woofer. Wondering if it is a problem with the particular unit that I got, I ordered a replacement. Unfortunately, even the replacement has the same signature output. So I decided to do something about it myself.

    Building a DIY 5.1 Audio Video Receiver – Part 5

    So far I have finished bringing up 4 of my 5.1 speakers in my DIY 5.1 AVR project. If you missed, check out part 1, part 2, part 3 and part 4 of the series. Next I wanted to bring up my sub-woofer. Since I have an active sub-woofer, I did not need any amplifiers to drive it. I just need to connect the output signal from my audio source directly to the sub-woofer input. But there is a catch. If you connect the audio source directly to the sub-woofer, the sub would be wasting a lot of energy which may heat up the driver and may damage it. Moreover driving the sub with all the frequencies will give boomy muddled up sound. So we need a low pass filter or a crossover.
