Can anyone comment on how best to determine what should be a subwooofer's crossover frequency while watching a movie and should there be any overlap of frequency settings with the fronts in case they are floorstanders? Moreover any tips on how best we cah judge what frequency tp set at crossover for subwoofer while watching a moview,

Plz take some time and experiment with the various crossovers in the AVR.....no one else can tell how much u prefer.Set the sub crossover control to max,volume to slightly less than half,do Audyssey and see if u like.If too much/less boomy, slightly increase the crossover in the AVR while playing some bass intensive movie (say,Transformers/Unstoppable) and reach a preferred point where the sub doesnt overpower other speakers/noises.

normally about 80 Hz or 100 Hz should sound good.
Typically, a well designed FS would start singing from about 35 Hz and a BS from 45 Hz. At that frequency range, sound is said to be non-directional till about 50-60 Hz. For good integration of the sub, there should definitely some frequency overlap. A good crossover setting should be between 60 to 80 Hz IMO.
Hi,
Apart from the above comment you have also said that front speakers being capable of handling 45Hz should be allowed to do overlapping. So does it mean that overlapping is fine to be done above 120Hz like fronts having crossover setting of 120Hz (meaning will handle 120+) and sub can be 160Hz (meaning 160-)?

Hi,
I have Denon791 (same as 1911), with wharfedale 9.5, 10.cs and 9.dfs, with sw150, after reading the manual I came to know that only bass frequency of speakers of "small" size is sent to subwoofer in default setting, means for me only surround speakers are small so sub is only playing those from surround channel, front and center are treated as large so they are playing the bass using there drivers.
either we need to set setting as LFE+main to pass all bass to sub, or manually make front and center as small.
somewhere I read about setting your cross over setting to 10+ whatever your speakers lowest frequency output.
I havent played much with crossover yet, need to fix my speaker placement yet.
During a home demo last week I have observed that LFE+Main gives better output than just LFE.
Yes. This has to be done by trial and error method and should be attempted after ascertaining the best location for the subwoofer, which again is by trial and error method.
Crossover should be 20hz + your minimum floorstand frequency. Eg. if your floorstand can go as low as 40 Hz then put your crossover to 60hz. This is the best setting. But ofcourse it depends on your setup and your listening taste. You can try the settings which sound good in your room.

He is right!!
120 Hz is too high for small/medium rooms. 80 Hz is Thx recommended for movie theater environment, but this dosent work well for small/medium home theater rooms. Here it shd fall around the 60 Hz range. In smaller rooms, the sub is placed closer to listening position. Hence sounds tend to be localized. This is why one shd cross over to sub around lower 60 Hz unless you have a king sized room. Else you can pin point the source of sub, which is not good.
You need to Experiment yourself!

Please don't mislead people and give bad advise if you don't understand electronics.
captrajesh put it right! See my previous post for bass setting. Crossovers are not set depending on ability on the floor standing speaker to play bass. Most FS play bass low down. So if one plays as low as 25Hz, setting it to 25 + 20 is like paying your maid to wash vessels and half way you decide someone else can do it now. You bought a dedicated Sub by paying good money for a reason. The sub's has one single job, to play the lower bass frequencies! The front has 3 things to do - Play Low bass, Mid Bass & Mid Range! So as much as possible without having localization effects, play bass from your sub. This will free up power for the mains.
Again, as much as possible, try playing lower frequencies in the sub without localization effects. Higher crossover you can achieve the better. This will free up power for the fronts. Freeing up power is really good for your speakers to play more 'freely'.

You know what? Learn to talk to ppl first of all and save your knowledge for yourself.! Thank you.!
By localization you mean overlap of frequencies between FS and Sub?

^^Did u try any of the suggestions here? What did u find? Let us know ur inferences. There is no definite answer here mate, just find what suits u by trial and error...there are only couple settings to vary, its not rocket science.Even if u find a suitable setting for movie, it most probably won't suit a movie setting(atleast in the various cases i have seen)-so just set it according to the mood,content etc
At present it is 80Hz and the mode is LFE+Main. But I am not satisfied in comparison to the performance that I had seen for some scenes in the shop. But unfortunately the AVR was different in the shop. I think settings need to be tweaked to improve the performance.

Hmm, seems the Audyssey setup could be the one to blame....or the differences in the acoustics at the shop and ur place.Did u try a complete manual setup bro?
EDIT: Which AVR was there at the shop? Hope not Onkyo as it would be very difficult to match then.Or was it another Denon model??

Manual setting I have not tried as I still need to provide some more time to get over the tech terms in the settings. Have to read throughh the manual.
