    Hi all,
    Looking at upgrading some Monitor 30 speakers I use for my rear speakers in my 5.1 setup.

    I'm looking for something that will really fill the room nicely. I like the 30s, but I don't think they really fill my room. They're loud, but I have to have them pointing right at me...

    I was looking into some replacements, and found the FXI A4. Supposedly these are better suited to fill a room.

    Room = 10 x 19.

    My question is, how do I place these? They have three sides to them, not 4.... What is confusing me is that you mount the flat side to the wall... and the other 2 sides have tweeter/woofers.

    Here's a link to the picture/description

    This might help to understand my room.

    Your front 60 are too close together.Since you oriented the room wide, not long, bi/di-pole won't work.Can you hang the 30s from the ceiling? Across from each other is your only option with the room layout.

    The 60s (actually 50s...) are about 6' away from each other.

    Okay- so my only option really is to keep the 30s? My ceilings are like 14' in this room....

    14 feet, even better. Wider sound dispersion. Your room is 10. You sit, what 9 feet?Front channel should be 9 feet.

    Front channel around 7-8'.

    I don't want to mount anything on the ceiling for a few reasons - 1: running the wires... 2: the wife... :)

    So it is fair to say the A4s, aren't going to benefit me in any way, right? I should stick w/ the m30?

    I see. I have them mounted currently - about 6' high. I could move them up, but won't I lose the effects? I mean shouldn't they be about ear level when sitting?

    In the future when I want to upgrade- is there something I should look for?

    Ear level would have been 4-ish feet. And assumes a proper speaker placement.You chose to do the room wide, not long, ergo...you threw proper placement out the window.Moving them up the wall, angled at opposite ends of the front of the couch gives them a chance at proper coverage.

    I'm not sure I understand.

    I can move them up to say 10'... But not 100% sure I understand what you mean about angling them.

    also the ceilings are vaulted... from 8' to 12'. Not sure if this matters.

    By the way, the 4/5 speakers should have 25-30 degrees to your rear. Not straight out.I will add to the sentiment, if your AVR supports height/width...utilize it.

    My AVR = Sony STRDH520 (7.1).

    I can't really move the speakers around too much in this room.

    I'm not really sure what the best option for me is... I could add another 2 speakers to complete the 7.1.

    I have two unused Polk OWM3 speakers. I was originally thinking I could mount the directly over the couch (main seating area) pointing downward...

    The other option would be to use these as front high speakers.

    The AVR does have IIz.Swap the 300 to the front if you want.

    I don't usually use any processing, but would you recommend using it?

    I'm not sure the best way to move forward.

    You don't have the layout for 7.1.You do for height and width, but your AVR only gives you the choice of height.I use both and another thread responder said to try it.What's the harm...?

    Okay, so in order to use the front highs, I must use llz?

    I always leave the receive set to AFD AUTO... so I'm not really sure how or what I need to do in order to get the front highs.
