Re: LSAF 2013
I'm looking forward to hearing it Fred. I do have a question though, I was under the impression that these were going to be active speakers. When you posted the last set of pictures, I noticed what looked like a crossover filter on the "seat" o...

Re: Pi Crossover Boards and Biamping
To separate the low-pass and high-pass inputs, you would need to cut two traces on the printed circuit board. It would be pretty easy to do, and you could even add a switch or jumpers for input selection. But thinking outloud, I wonder what benefit tha...

Re: Pi Crossover Boards and Biamping
The connectors on the π crossover PCB are just 0.205" spade lugs for printed circuit boards. You can get them at any electronics supplier, Digikey, Newark or Mouser, for example. Do a search for "PCB Quick-Fit Male Terminal 0.205" and yo...

Re: 4Pi's Biamped?
When I develop crossovers, I use a processor that serves as an active crossover configured with a Spice model. It allows me to change "components" using a configuration file. Once I have it fully optimized using Spice models, I build a physic...
