Time alignment tool for speakers

[rendoman]

Thank you all very much!

I know that's a pretty strange tool for the forum
It's uncommon to find people with the need of tuning a multi-way speaker system at home.
PJs you're right about time alignment and lobing, it's an undervalued concept, even in common production speaker. I'm trying to collect the best methods to make a system sound better.
Surely Dsp and sound processor with active crossover are powerful devices to play, my inexpensive dcx2496 has an autotune program (with microphone) pretty accurate for short and long delays, phase and correction. I think in a passive system it would be an hard job to solve the problem, above all if all drivers are inside the same cabinet.


Good idea Toolmaker about using the 45° mill head with a 4 flute end mill, I want to try!

I'm still working on plasma tweeter, I will modify soon the prototype, hoping the results will be enough this time, I want to try also a powerful oscillator with GU81 tube.
