Anyone notice this second generation F-12? I tried the first version and returned, but wonder how this one sounds.
The FS is around 59 Hz. now, up from the other one that I think was in the low 30's. They got rid of the plastic phase plug
of the first one. I didn't care for the looks of the plastic one. On the Lii Audio site, it looks to still be the first version. I sent them a note
requesting info, but no response so far.
Some info from a different site other than Lii Audio:
Lii audio's new F series full-range unit f-12, full paper cone design, small stroke, high sensitivity, typical antique horn style, mellow mid-frequency, low-frequency dive is not deep but there is a thick sound, modern The craftsmanship design retains the antique flavor and improves the resolution, changing the dull style of antique speakers. The mid-to-high frequency has a good texture, and it performs better for vocals, instrumental music, and classical music. The international standard anechoic chamber test QTS value is 0.742, which is very suitable for small baffles.
The full-range speaker does not need a crossover, it produces a single sound without phase distortion, and the sound is more natural and pure.
Our full-range speakers have tried to adjust the sound to be very balanced. It is not recommended to add a notch filter. We think that the limiter changes the horn waveform forcibly and changes the sound of the horn. The inductance, resistance and capacitance of the notch are bound to It will cause sound staining and affect the efficiency of the speaker. The full-range speaker is simple to play, and the pure sound brought by the signal pass-through does not need to be complicated. It is better to change the sound of the speaker through physical adjustment rather than the circuit. Of course, the overall quality can be improved by upgrading the speaker. So please don't use the superfluous thing like wave limiter to play full frequency! Please do not use unnecessary things like wave limiters! Please do not use unnecessary things like wave limiters!
