I'm not sure if I'm wording this correctly... I'm building a box for my manager for his two ds18 exl 12inch 2500watt subs... I've tried googling it, but I can't find any info for using a port in between two subwoofers in a 'parallel isobaric load'? If thats the correct technical definition? I'm...

Hello everyone! Over the past few months, I've built a 14-band spectrum analyzer using 280 RGB full color LEDs and laser cut and frosted acrylic blocks. Here are some pictures: Do you like it? If so, please give it a check and drop me any your feedback.

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...

Hello everyone I am still embarking on this open baffle journey. I currently have a passible analog crossover for the Kef Q100 coaxial woofer and tweeter driver in the baffle. My goal is to actively blend two woofers coming that will arrive Wednesday and be placed on the same baffle...

Hi guys, I have little class D board as can be seen here: Would like to use it bring back my dead Edifier R1280T (already turn in to passive speakers) and add some sub. Was using little class AB board but not sub output. Unfortunately after playing sound amp noise floor jumping up and there...

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...

Hello everyone! All my materials are coming in today, so I thought I’d start a build log. I’ve been lurking & learning for a while but recently I took the plunge and ordered these speakers. The Philharmonic Audio Affordable Accuracy Quick Kits are put together by Dennis Murphy, and as of today...

I am proud to announce the release of Rev 3.0 of my award winning PecanPi® product line. The PecanPi Streamer is a networked music player with build-in DAC and headphone amplifier. The PecanPi DAC is high-performance DAC for the RaspberryPi and Tinker Board, this is for DIYer...

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...

Found a good store for DIY. https://www.lautsprechershop.de/intro_m_en.htm

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...

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...

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...

Join me as I discuss DIY amplifiers with Toid's DIY Audio, this Saturday at 10am EST. Toid's Links https://toidsdiyaudio.com/ https://www.facebook.com/123Toid/

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. It did lose the audiojack from the Pi 4b. Now OSA Electronics released a DAC/ADC module used specifically...

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...

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...

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...

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...
