    Can large oil painting work as acoustic diffuser?

    I think acoustic diffusion is a good example of the pursuit of perfection being the enemy of the good enough. Just add stuff to the room. It adds up and it helps.

    Can large oil painting work as acoustic diffuser?

    I hung a roughly 2'x2' oil painting with an ornate carved frame on the left wall pretty close to the speaker. It made a noticeable difference, and did improve the sound quality. At the time, I thought it was more the frame than the painting. But I really don't know. I would think that texture of...

    dCS threatens with a 7-figure lawsuit over a review

    As an engineer, I recognize you being a good engineer by stating what you are testing, the test equipment, the methodology, and the results of the test. It's completely repeatable.

    dCS threatens with a 7-figure lawsuit over a review

    I don't think dCS should sue anyone. I think they, and everyone else, should just ignore these subjective reviewers and reviews. I made it through about two thirds of Cameron's review whilst fighting off nausea. He really is clueless. If you are going to go on YouTube and spew a bunch of...

    What is the Science behind putting loudspeakers on spikes?

    I've tested these tables. They performed best when all the air was taken out of the suspension.

    What is the Science behind putting loudspeakers on spikes?

    Spikes minimize the movement of the speaker cabinet. Less movement of the cabinet means more accuracy of the drivers.

    Extension cable and ground wire for my turntable

    Phono preamp to amplifier is amplified. So it shouldn't be a problem. I have similar length RCAs in my surround system. No issue.

    Extension cable and ground wire for my turntable

    The ground wire doesn't matter. You can just connect any old piece of wire. The signal from the phono cartridge is of extremely low voltage, and is very delicate. It should be protected. It is generally not recommended to extend this cable. Losses in the all important signal from the source...

    SOS! Suddenly have a high-end turntable, need to upgrade Amp + Speakers

    For an integrated amp within your budget, I recommend the Rega Io or Bias. Pair that with some Wharfedale, PSB speakers on proper stands.

    Front-ported vs rear ported monitors close to a wall? Is there really a difference?

    I have some rear ported stand mount speakers. The manufacturer recommends close to the wall. They sound best 3 to 4 inches away. I recently set up a pair of front ported stand mounts and the same manufacturer recommends a minimum of 9 inches from the wall. So it depends on the speaker and what...

    Center Channel Help

    Sound will escape the room via the windows much more than through walls. Play some music loud and go outside and listen. I didn't want to advise this until I knew you were in a house, and not in a high rise. :)

    Center Channel Help

    Yes. I use curtains to absorb some high frequency, There is a big area rug between speakers and listener. "Stuff" in the room like paintings on the wall, ceramic vases, etc diffuse the midrange. It seems that cylindrical or spherical (hemisphere) shaped items work well for this. I use DSP to...

    Center Channel Help

    In my main listening room with the higher end system, I use rather heavy curtains from Ikea to tame the high frequencies. It works great. There's no need for special acoustic treatment panels. In the theater, I have a 5.1 system. I acquired mostly second hand kit to build it, so it progressed...

    Center Channel Help

    I forgot that I had put some sound absorption on one wall in the form of a rather large Japanese screen artwork. The room was a bit lively before. This helped as well.

    Do you hear a difference with DAC filters?

    I have a Rega DAC that I no longer use much at all, only for headphone use. It has five filters. I could never hear any difference between them.

    Center Channel Help

    When I took the center channel speaker off of the rack with components and put it on it's own stable stand, I was much easier able to understand the dialogue in movies.
