Have any of you just plopped a LCD monitor on top of your subwoofer?



I have a new LCD display coming.

It's bigger than the current one.

It seems like it would "fit" my space best if I just set it on top of the subwoofer.

The whole idea seems dirty.


I know it wouldn't work at all with my aperture grill Trinitron that is being retired.

Maybe someone can talk me out of it with some tech facts about LCDs?


Thanks.


best regards,
mike

    I'd be reluctant to do that, even though the solid-state LCD is undoubtedly going to be more resilient to vibration than a CRT. After all, LCDs have been installed in cars for awhile now and seem to do alright. If that's even a valid comparison - I dunno.

    With a 30" display I'd be more concerned about making sure it doesn't block or reflect sound from the speakers. I have a pair of 20" displays here, and even set as low as they go and pushing them back as far as possible they still interfere a little bit with the sound. I've been considering a custom desk that would allow me to position them lower, maybe even doing like they do on the TV news desks where the screens don't protrude past the desk surface.


    All else is in doubt, so this is the truth I cling to.

    I'm on the same page with you Dave.

    I don't want my display monitor causing sound reflections that muck up my direct impression.

    I want the display monitor behind my speakers... but I like to keep the speakers a little further than "near field" and right at ear level for when I am sitting.

    My new mix position is in a smaller room than I am used too and I am using near field placement rather than the near-far I prefer. I'm doing this to keep the speakers off the walls and indeed my RTA analysis seems to show that it is an effective way to use this particular room.

    My subwoofer and the display seem destined to be in the same place.

    I am excited to think that I may be able to replace my desk with something minimal because I want to get rid of that reflective surface too.


    I better dream up some sort of stand.

    Thanks.


    best regards,

    mike

    Is there no room to put the sub on the floor and/or off to one side? 

    I originally had mine on the floor centered between the mains but I was paranoid about kicking it so I moved it to one side. When I then re-measured the room I discovered that the new location was actually much better acoustically. Which makes sense - centered between the mains meant centered in the room, too.

    Sub on a floor? At McCue's place?

    Oh behave.

    :-)


    To answer your question,  Yes, but No.


    Right now I have it sitting on an old set of cast iron wood stove legs. I keep it just off center. The center of the driver cone is about 24" off the floor. It is lower than the L/R speakers but not on the floor.


    I have a bunch of 8 lb/cu ft. in the corners but I haven't really settled on the mix position location yet so I am really depending on the near field, direct impression where as I prefer some distance if I can get away with it.

    Ideally I'd have enough distance that I could have the L/R pair and the sub far enough away that I could jog the sub to the left or right while preserving close time alignment for the direct wave. The effect on time alignment of jogging the sub off center is greater when you are up close to the array.

    I'm trying to find a balance that is appropriate for the dimensions of the new room.

    I tried working with the speakers 10' feet back, as is my preference... this room doesn't work for that. I hear to much room and not enough direct emphasis.

    Thanks so much for letting me bounce ideas around with you.


    Maybe I need another sub woofer? :-)

    all the best,
    mike

    I used to think that multiple subwoofers was a silly indulgence, until I read Floyd Toole's book. No single book in my entire collection has yielded as many epiphanies as this one.

    I had originally wanted to raise my sub off the floor with some kind of heavy platform, but never did because I just couldn't find anything dense enough. Intuitively, it just seemed like a good idea, especially since it was sitting on a wood floor (with a bedroom immediately below). However, subsequent reading made me question that assumption, as there are fewer acoustical issues when the sub is directly on or close to the floor. Especially now that it sits on a concrete slab since I moved out to the garage last summer. So it now sits on the floor, to the left of my left main speaker.

    A height of 24" shouldn't be an issue, though, as long as your crossover frequency is fairly low, say around 60Hz.

    That would be very inconvenient to work flow.... as my sub in on the floor and behind me.... It'd be a pain in the neck to try to work like that.
