Goldwood 1858 OB 2-Way - Vocals in woofer?


2011-08-20 6:02 am
I have a system I am trying to optimize with some Goldwood 1858 Hframes, and am curious how many of you use a below 80hz XO point? I had 100Hz XO 2nd order lowpass frequency but could pick up bits of voice. Now it's about 60hz second order, and better... but I see people using these up much higher than 60hz. I know it's not preferred to get vocals with subwoofers, but what about the HFrames in a 2way? Should I seek to minimize or eliminate vocals in the low end?
Phonated vocal range:
In terms of frequency, human singing voices are roughly in the range of 80 Hz to 1100 Hz (that is, E2 to C6) for normal male and female voices together.

Fundamental Speech frequency:
The voiced speech of a typical adult male will have a fundamental frequency from 85 to 180 Hz, and that of a typical adult female from 165 to 255 Hz.

The leaders in dipole design have received very good reviews for 4-way speakers that provide a controlled polar response over a very wide frequency range, which a 2-way dipole can never deliver. Perhaps with your 2-way dipole you are hearing abrupt changes in polar response(energy vs. frequency at the listener), some cone break-up just above 1.2Khz, and substantial beaming with comb lobing above 1.8Khz (13550 in/sec) / 7.2" diameter.

A 2-way dipole often has a 1-person sweet spot width, and requires careful toe-in to aim a lobe at the listener.
