Speakers/sub creossover
I have the whole series of lsi including lsi 25, lsi 9, lis center, f/x. My sub is optimun 12 ( 2 pairs mix ) and my reciever is denon avr 5308 together with xpa 5.
My questions are: What should the crossover frequency settings be for all my speakers from my avr? Also, what should be the setting of my subs from my avr ?

Use 80 hz as a starting point and set to whatever sounds best.
-
Are you refering to all my speakers or to all my speakers plus subs? After setting them to 80 hz, what will I get if i go up from 80 to 120 or go down from 80 to 40?

Should I set my speakers up from 80 to 120 or down from 80 to 40? What about my subs? What should be its settings? -

Thank you so much for your promt reply to my post. But I have one question for you if you don;t mind. Whne you say sub..... crossover 60. What/ where willl I find it on my avr 5308 or on my optimun 12 on the front panel? I am asking this question because I have 2 optimun 12 mixed connectoed to my reciever, Also, Should I put the setting to LFE + main or LFE + THX on my receiver? -

1.- Denon: Manual Setup ¬Speaker Setup↓➎ Crossover Frequency⇒Avanced
2.- LFE = 120 Hz (http://www.dolby.com/uploadedFiles/zz-_Shared_Assets/English_PDFs/Professional/38_LFE.pdf)
3.- Velodyne Manual Page 3.- Low-pass Crossover - 40 to 120 Hz : All inputs sum the left and right channels together, with the resulting signal passing through an
adjustable low-pass crossover beforebeing amplified. The crossover control allows you to adjust
the upper limit of the subwoofer’s frequency response from 40 to 120 Hz. The subwoofer’s
response will begin rolling off above the frequency you set this control to. You should set the
crossover frequency to obtain a smooth and seamless transition from the subwoofer to the
main speakers in your system. If your main speakers are smaller with limited low frequency
output, you may wish to choose a higher frequency (such as 100 - 120 Hz) than you would with
larger speakers which have greater low frequency output. The default crossover setting is
80 Hz. With larger speakers, you may want to set this even lower, for example 70 Hz.
Velodyne Manual Pag 7/8/11(1)LOW-PASS CROSSOVER
Use this knob to select the frequency above which you wish to roll off the signal to the
subwoofer. When the knob is turned all the way to the left, the Subwoofer Direct feature
is invoked and the subwoofer plays all frequencies up to 200 Hz.Low-Pass Crossover
Both sets of inputs sum the left and right channels together and the resulting signal is passed
through an adjustable low-pass crossover before being amplified. The crossover control allows
you to adjust the upper limit of the subwoofer’s frequency response from 40 to 120 Hz. The
subwoofer’s response will begin rolling off above the frequency you set this control to. (See note
above about frequency limits.)
You should set the crossover frequency to obtain a smooth and seamless transition from the
subwoofer to the main speakers in your system. Do this by listening to the blend between your
satellites and subwoofer using familiar material. If your main speakers are smaller units with
limited low frequency output, you may wish to choose a higher frequency (such as 100-120 Hz)
than you would with larger speakers which have greater low frequency output. With larger
speakers, you might start with this control set lower, such as 70 Hz.
Subwoofer Direct
Subwoofer Direct is the leftmost setting on the low-pass crossover knob and will allow
frequencies up to 200 Hz into the subwoofer. If you arenot using an external crossover, we
recommend that you use the one provided within the subwoofer for optimum performance.
Caution!!!
To avoid damage to your main amplifier, be sure to maintain correct polarity when making all
connections. Red (positive) to red, and black (negative) to black. Be sure that all connections
are tight, and that there are no loose strands or frayed wires.

Thank you so much once again for your help. I will absolutely follow your advise. So to summarize everything you mentioned in your reply, it only means to say that I should put my speakers on my denon to 80hz and set the LFE + main to 120hz. Also, set my velodyne to 80hz on its front panel. Am I right in my interpretations of all these excellent tips of yours?
Another question. which one do you like the most among your four options # 1, #2, #3 or #4? and WHY? -

THX: is cinema mode. If you use THX, everything will always be 80 HZ and automatically makes the AVR.
LFE is a different channel. Not to be confused. See link to Dolby.
I prefer 60 Hz without using LFE +. Leaving work to the subwoofer.
4 is the most successful low. Remember every house has a different acoustic. Let your ears be the judge. -

Thanks again one more time!!!
I will see to it that everything you mentioned is well followed for my settings!

Ok.
To honest with you, I did exactly what you told me to do in this forum and the result is perfect. I did the application to my two systems, in my room and in my home theater room. They sound amazing than ever before. I really do love to listen to my musical sounds.
Once again, Big thanks to you, my new friend!
