How are you able to incorporate ribbons and dynamic woofers in a flat frequency response speaker, where so many have failed?
This calls for a booklength response. I’ll give you a few short pointers: 1. Use push-pull ribbons. Single ended waveform fidelity is terrible. You only build a ribbon single-ended to save money. 2. Use low crossover freq. Right now no ribbon mid we have crosses over higher than 166 Hz. 3. Have the ability to adjust levels with great precision. Our electronic crossover permits 0.01dB increments per channel. 4. Build passive crossovers to very tight tolerances. For us that means four decimal places, or 1/2000th of 1%. We laugh at the tolerances (5%, 1%) even the best competitors use. How much of an improvement (if any) would you get by using the active crossovers as opposed to the passive crossovers? Are active crossovers for the ribbons more complex than the standard 24db/octave units you can get from some place like Marchand? I only like to use steep filters in lowpass applications. 24dB/oct is in phase but has about 10msec delay at 100Hz. Also, steep filters ring, and the high pass s
