I did not perform any off axis measurements of my DIY speaker. I did the typical measurements on axis including reversing the phase and adjusting the delay to get the best null for the crossover. With the 4th order LR crossover driver overlap is not going to be a big problem. With a flip of...

I did. I used the exact crossover frequency and slopes. There was a bit of filtering required to get the tweeter response flat to start with before applying the crossover filters as the waveguide boosts the low end. A few notch filters were required to really crush the cone and dome breakup...

https://www.audiosciencereview.com/forum/index.php?members/davey.86600/ I started with the drivers centered but then changed it up. The horizontal offset was carefully calculated to produce a very flat on axis response from the original speaker that used a very wide dispersion midrange that...

I have lusted after this speaker for years. Reading the white paper made me a fan of the wide baffle. Great to see this review. A few months ago I realized I had the parts required on my shelf and could modify one of my old speaker builds into this configuration. I loaded a stock DXT tweeter...

Madness really. I want a high resolution DC coupled phono preamp that allows me to recreate the record groove profile without phase error at low frequencies. I have always wondered what it was that many people like about the sound of records, so I went deep down the rabbit hole investigating...

Brilliant. Thank you. It did not occur to me that there would be an internal digital filter. My measurement found a 2.4 Hz cut off that matches nicely with the spec for the internal filter. Looking at the data sheet for the AKD5554 I see there that holding pin 44 high enables the HPF (high...

I have been fascinated with the idea of building an omni-directional speaker for some time. I have now built two pairs. The first was about 6" in diameter with 20 one inch Aurasound Cougar drivers. The second is about 4" in diameter with six of the 2" Aurasound Whisper drivers. I used...

I would like to modify inputs 3/4 to be DC coupled. Before I crack the case open I thought I would ask if anyone as looked at this and identified the bypass capacitors in the circuit. It would be great to see the schematic first, but I have not seen one posted. Thanks
