    DIY Surround Pre-Pro: Apple Logic Pro + Dolby Atmos

    TL, DR; What if we could configure Apple’s Logic Pro to be your Surround Preamp-Processor (including up/down mixing); Control input selection and output levels via Focusrite’s Rednet R1 controller; and Send the input/output channels wherever you need via Dante? PREAMBLE We all are very aware...

    3D Printed Aurora Borealis style headphones

    Hi all - I posted this over on a couple of other forums, but ASR is where I spend the most time and wanted to share this. This is pretty much near final except for I don't think the headband is perfected. I don't have a GRAS to measure, but they sound decent to me. I have a simpler version where...

    I built a sub - the Overdrive10

    Over a year ago I posted here that was searching for a design for a DIY sub. There were several great suggestions, but I ended up going with the Overdrive10 designed by @Wolf. It's a bandpass design with a 10-inch Dayton driver and a passive radiator. I bought the hardware a year ago and finally...

    DIY Phono Pre Suggestions

    Good day all. Pretty self-explanatory really, any suggestions for an acceptable DIY phono stage? I tried to order the Muffsy kit but alas, Brexit/Covid related issues mean they aren't sending them to the UK. Preferably nothing requiring proper engineering prowess, as this is one of many areas...

    Class A Amplifier Using IXYS Fets :)

    I thought I would share my Second Class A F5 amplifier using IXYS fets, the first one uses more components, the second version is very low part count. Sharing the Video of it being powered up and running ( first power up on this design ) Soon will connect my QA401 and do some measuring. Not...

    Active center speaker on a budget

    My very first serious DIY speaker project was a centre speaker about two decades ago. Back then I was already aware of the fact that a horizontal center speaker usually does not have a decent off-axis response. So my center was vertical, comprising of 2x Monacor SPH-135KEP, one of the lower...

    SEAS Coaxial 3-Way Design Log

    This thread will serve as my log for iterations of this project. I am sharing it publicly for reference and constructive criticism. I am not a speaker design expert, or an audiophile guru. I'm some nerd with irregular, long bursts of free time and a rabbit hole. Building speaker kits was very...

    Maybe some of you already now, there is now an updated RB Pi 4 module, that's called the Pi 400. This has an integrated keyboard and has some small performance updated compared to the Pi 4.

    I turned one of my amp circuits balanced but I can't understand the point.

    I've been designing and building my own amplifiers for years as a hobby. They all sound great. I've been meaning to go balanced since last year, finally I had some time to make a circuit but I don't understand the point at all. Please ignore the power section. In real life I'm using a center...

    Q100 speaker as surround in sealed small enclosure

    Hello Everyone, I have two pair of KEF q100's I got for super cheap. They sound great for my surrounds but even better when I plugged the ports. I was wondering for home theater if I could make some pretty tiny sealed boxes to be able to place these tiny things just about anywhere. Looking...

    Small Subwoofer Drivers in Tower Speaker

    Hey all, I've been reading more and more about speaker design since I built my first set and I have an idea I'd hope to be able to execute in a few years. The 4" Tang Band midbass drivers I have on my desk are impressing the hell out of me with their low end. Tang Band clearly knows how to...

    Worthwhile Plate Amp Candidates<=100W

    Hey all, I've been having fun with my recent DIY speakers, but I'm routinely disappointed with my hand-me-down, buzzy receiver or my distorted at high volume, no headroom desktop budget all-in-one amplifier. I like the way my buddy's JBL LSR305's are set up on the back, and as much as possible...

    Find my sub!

    I'm busy changing my setup a bit. The idea is to hide most of the nasty stuff. So mostly get rid of the cables and equipment and make it look clean. The idea was to use an Ikea BESTÅ enclosure and TV mount, hang it on the wall and hide everything inside. The middle section is used to house a...
