Back on track... more basics questions

I'll post up a pic ASAP so I can show how far out on the shelf the speaker has to sit in order to clear the lip of the top shelf where the TV sits. I have pictures posted in the member gallery that might show what I'm talking about. The MoPADS' elevation wouldn't be a problem since I still have one set of holes left for the shelf to be adjusted down, but the rubber ball idea wouldn't work because I need to project the speaker out

Probably another case of me making things more complicated than they need to be, but that's me!

I can understand why you wanna make things more complicated than nessesary, being a dlp fan
Home depot has a floating shelf, uses two metal poles stuck to the studs, and the black
shelf has two holes in the back, will hold a CC pretty good, just drill a hole in it for the speaker wire.
It'll hold about fifty pounds or so, and dont worry about hearing loss in one ear, just set your levels from the listening postition and your set.
Worry about speaker placement isnt really warranted anymore, DD allows you to set seperate levels to compensate, unlike prologic plain where the backs shared a channel

I can always count on you can't I pix?

So now you're telling me to go back up top with the speaker? You guys already convinced me to leave it underneath and point it up. I already wasted ~$30. on a swivel stand that fastens to the wall, but like I said it didn't project the speaker far out enough to even it with the TV screen, so no more of that type of option.

Why is it important to get your CC even with your screen?
There are some that will tell you your CC needs to be even with your l+r's, your CC needs to be a certain way etc, and its just so much fiddle faddle when you can set your level to compensate.
If a spl meter reads 70db (dolby reference) from a certain channel it doesnt matter if the speaker is sitting on the moon, it should sound okay.
And imaging is gonna be a prob with you with hearing loss, anyway, somethimes a ear infection flares up and I lose stereo (or my lease, turning up one channel to compensate)
DD is awfully forgiving, a decent soundfield is not nearly so hard to produce as some would have you think

[pixelthis]

OF course you want to point those tweeters in your general direction to get some of that great B&W imaging.
I've done some police work (no white collar stuff so dont worry) and you would be surprized to see hpw much changing your source object changes how the destination turns out. Raising your CC with a few coins (or lowering) can change the sweet spot
by several feet.
And if anybody paid 19.95 for that airconditioner foam, you got ripped, somebody cut it to order and is making a fortune

The reason the center has to be even with the shelf,or stand that it rests on is to avoid reflections from that shelf or stand that it rests on.Setting the levels can't compensate for reflections of sound waves.There is far more to proper set up than setting the levels,proper placement is key to building a good soundstage.

It's not real easy to tell from this picture the lip that overhangs the TV stand's compartments, and I've since eliminated the glass speaker stand because it wouldn't allow me to point the CC, but my concern is getting the tweeter extended out past the decorative curved molding on the top shelf where the TV sits. The MoPADS were only $25. shipped, and if they don't work out I'll use them for one the rear surrounds and buy another set for the other one. I realize that ideally the CC should be even with the screen, which isn't possible in my case, but what I read here tells me that the face of the speaker cannot have any obstacles or reflection surfaces nearby, so that's why I'm trying to angle it and project it out from the opening in the TV stand. The fact that the MoPADS will raise it 1.25" won't be a concern because the glass stand used previously raised it the same distance and there was no problem with clearance then. The MoPADS will provide two benefits: point the CC at my ears (crippled though they may be) and de-couple it from the shelf.

This is good advice. Despite what some would believe, frequencies below 1000 Hz or so will "wrap" around the speaker. They don't just shoot straight forward.

The bad part about the reflections caused when the speaker isn't even, is that they lie in the mid-range,where our ears are most sensitive to such interference. You don't want reflections smearing the sound, especially if they're easily avoidable.

With center channels, most designs assume the speaker will have close proximity to a TV screen or wall as well, sort of a built in baffle step compensation for step-loss.

I'm sorry but spending $19.95 on a product that meets your needs is not getting ripped. My CC sits 3 ft above my mains. A few coins weren't gonna cut it. I have my CC angled exactly how I want it now and the decoupling is a added benefit. They look nice too. A thumbs up from wifee is always a good thing

[Rich-n-Texas]

Yeah. What he said!
