question about speakers

[dj_yerba]

hi, i have an onkyo txsr 502 receiver and 4 polk monitor 50 speakers, 2 of them connected to A speakers and the other 2 conneceted to the B speakers... but when i select a+b so all four to work at the same time i noticed that the B speakers sound lower than A speakers... WHY?

and last night i selected all of them to watch a movie i noticed the B speakers sounded higher than A speakers... the dvd is connected with optical cables so in the monitor of the receiver says 3.2.1... why?

so if choose music i have A speaker higher than B and if i choose movies i have B higher than A... why is that happening? all i want is the 4 speakers to work at the same level

all speakers are polk monitor 50 (8 ohms)

Check your setup...

...according to the owners manual, speaker levels are adjustable at least for the front, center, surrounds...although they seem to reset in "standby"...there seems to be no adjustment for the "B" pair(as they seem to be delegated for use in "another room" in the literature)...which brings up an interesting question. Are you not using the "surround" modes? Am I missing something?

There are some other things I noticed while perusing the manual, when "B" pair is chosen, "A" pair defaults to stereo and some other things...switching into different modes may also affect levels...there are probably "pre-set" parameters for video that are different from audio only...

yes, when i set both speakers to work together, the A speakers are adjustable from -12db to +12 db, but it seems that the adjustment also works for the other set of speakers, if i rise to +12db the B speakers also rise their volume but always inferior to A speakers.
when you use both A+B speakers, sorround is not allowed... also i can't adjust the b speakers as i do with the A.

what i can do is to set both speakers in direct mode (from onkyo) that makes all speakers to a relative same level, but unfortunately this also sacrifices the bass and treble... so i can only choose between stereo (with the original problem of A speakers sound higher than B) or to direct mode or pure mode which is very similar to direct mode.

what really bother me is waht i mention in first post... when on music mode a is higher than b, and in movie mode b is higher than a...

Why 4 speakers with 2 each on A&B? What is the benefit to that? Especially if they are in the same room. Sounds like your making it harder than it needs to be.

Why not just use 2 mains? Two balance mains would probably sound better than 4 mains at different levels. For digital why not use 2 mains and 2 speakers as surrounds and select "Phantom Mode" or "No Center" on your receiver for the leck of center channel? You can also use "all channel" or "7 Channel" or what ever it's called on your receiver to play all channels the same. Granted this involves digital processing but it should sound better than your set up now with it's sonic limitations.

i thought of 4 just for audio purposes not for movies but due to first post contradiction on music and movies i posted that question to hear from others why is that happening (music= a higher than b / movies= b higher than a)

why 4? i thought of one on each corner of the room for audio listening and movies. i believed that 4 at same level on each corner will give me a lot more feeling than 2 in front of me when relaxing.

i have a center and surround speakers but i kinda not like it so much. but i guess i'll give it a try to set up 2 on the main and 2 on surround with no center.

Use one of your DSP modes to do the same thing more effectively.

It is called 5 channel stereo.
