Just wanted to know, I just got a new receiver. Sc-25.
I have a velodyne dps-12 sub.
whats the best scenario when setting the crossover?
1.) Let the receiver handle it only at 80Hz and set the sub knob to DIRECT
2.) Set it only on the sub
3.) set it on both (which is what i think i had done previously). basically set the sub and receiver to 80Hz, is there any harm in doing so?
Lastly, is 80 Hz the best setting? I set my speakers to small, because i want most of the bass to pass to the sub.
do most of you leave it at 80?
thanks
Let the receiver handle it (i.e., do choice 1, although you might choose a different frequency [see below]). Do NOT do 3, because then you will have both crossovers filtering things at the same time, so you will likely have a dip in your frequency response at about the point of your crossover setting.
As for whether 80 Hz is the best frequency or not, that depends both upon your other speakers and your listening preferences. You want a frequency that is above the -3dB point for your other speakers, but you do want to keep it fairly low. If all of your other speakers are efficient and have solid bass down to 40 Hz, you might want to set the crossover at 60 Hz or so, but even so, there is nothing wrong with using 80 Hz anyway. Which would be better is going to be dependent upon whether the subwoofer or the other speakers (along with the receiver) are better able to deal with the frequencies between 60 and 80 Hz (in my hypothetical example), given that they are also called upon to reproduce other frequencies. And that may change depending upon what, exactly, you are listening to at the moment. Since it is impractical to change it all the time, I recommend that you select a frequency that is at least 10 Hz above the -3dB point of your other speakers, and is at 80 Hz or lower. With the hypothetical example, you can try both 80 Hz and 60 Hz and see if it seems to matter. If it does seem to matter, select whichever seems better to you.
Edited to add:
I just noticed that I responded to another post of yours regarding your speakers. Those PSB B15 monitors are flat down to 70 Hz, so set it at 80 Hz and no lower.
