need some help please about 800 series

i have 804di with no subwofer ..
now someone recommended me to put the lx85 pioneer reciver with subwoffer "on" and x-over 80HZ

if i'm not going to add a subwofer soon should i change it to no
so all the frequency below 80 hz will go to the speakers?

i try to understand if it might damage the speakers to deal with very low frequencies

Neither. The 804D2 are incapable of producing LFE and trying to drive them that hard will needlessly tax your speakers and your amplifier. And setting the crossover point to 80Hz zaps any chance to hear low and mid bass. Rather set the 804D2 to LARGE and ENABLE the subwoofer (even though you don't have one). You still won't get any LFE but you will get the full benefit of the 804D2s without any undue strain.

I would set the amp to 'Large' and also tell it that there is NO subwoofer. If you tell it that there is a sub, you'll get no frequencies below 80hz from any source (Including music!!) which is not good.

LFE is NOT bass. You'll get full bass without LFE the way I described. The way you described the 804D2 will get both and that should be avoided.

I agreed with you, is no possible with the 804D get good LFE performance and additional to this if you don’t have a dedicated amp to feed the 804D is not way possible to you get a decent bass from them, set your speaker to large and in bass setting put LFE+MAIN (that is the way I set my 804D) with this set up the bass for the main is not inferior to 40 Hz so you are not feeding the 804D below of they can receive and your AVR could not be hurt with some requirement that it can't handle.
it's just IMHO :T .

i have m6i connect to my 804di.. i dont think it changing anything
the reciver set to subwofer - yes and front large.
so i will not get LFE below 80HZ

well i think i need to buy a good subwofer soon

i have m6i connecting to the 804di.. i dont think its change anything
i just put it subwofer yes and large so no i not getting LFE below 80HZ

well i think i will must buy a good subwofer soon

Or I see that you have a good amp, well you have only one option and you know which is.

[RebelMan]

well i think i will must buy a good subwofer soon

For movies it's a requirement. For music it's unnecessary (in your case).

[nimrodasas]

its really the feeling i get that in music everything perfect and still somthing missing in movies...

[nimrodasas]

thanks for you help!!!
just wanted to know ,
i want to buy b&w subwofer..
i have 3 meterX 4 meter room..
is db1 will be a over kill? i know it has calibration system so ..
i want it to be a long term buy and to fit a bigger listening area in the future.

The DB1 is large and feature rich but it wouldn't be overkill if you can accomodate it. Subwoofers are prone to make a lot of distortion and good subwoofers can be expensive to make. But you could get better results deploying two lesser subwoofers than one expensive one especially if you plan to integrate them with music sources. As always there are tradeoffs but in this case the tradeoffs are in many more ways worth it.
