OK, so I bought this pair of CDT HD-2BL Hybrid Mid-tweeters. Their frequency response is rated from 250Hz - 20kHz. I contacted CDT about the proper high pass frequency and they recommend 1500Hz at 24dB/Oct.
Now, building a 4th order passive crossover is easy enough, but my question for the audio gurus here is which style?
- Bessel
- Butterworth
- Gaussian
- Legendre
- Linkwitz-Riley
- Linear Phase
I never really knew the differences between these and I'm hoping someone here does.
