Title: Center speaker placement woes
Post by: Danny Boy on September 18, 2015, 02:43:39 PM
I recently replaced my plasma stand, only to find that now I've got nowhere to place my center speaker, since it's 140mm high while the tv's bezel on the inside is 60mm from the stand.

My initial idea was to use the tv's VESA mounting and build a stand from 2 piece aluminum square tubing going parallel to the top of the tv, another 2 piece horizontal (from the back of the tv towards the wall) on top of the vertical tubes with 1 or 2 braces. (I didn't want to put up a shelf or drill into the wall.)

I decided to google for some ideas and saw this, which was more-or-less what I had in mind (sorry for the poster's original pic).

Then I saw something else. Well, here is my result:

Basically what I used was:
1x 1830mm Double Slot Wallband R75.99 http://www.gelmar.co.za/shelving-and-brackets/wall-bands/wallband-wallband-system-1830mm (http://www.gelmar.co.za/shelving-and-brackets/wall-bands/wallband-wallband-system-1830mm) Much too long, but rather safe than revisit the store. I've got a 60" tv and the 1220mm would have been sufficient
2x 220mm Double Slot Bracket     R27.98 http://www.gelmar.co.za/shelving-and-brackets/wall-bands/double-slot-bracket-220mm-wall-storage (http://www.gelmar.co.za/shelving-and-brackets/wall-bands/double-slot-bracket-220mm-wall-storage)
4x M6 screws
4x wood screws
400mmx225mm MDF (which I had)
Rust-Oleum black spray paint (also had some)

I don't think it's necessary to describe what to do with the above.

I will point out a couple of things:
- I opted for the double slot system due to sturdiness of the brackets - very little movement. If you secure the shelve, the single slot system would work just as well taking the cost down from R100 to maybe R40 (they have in the store, but not on the website)
- The pre-drilled holes in the wall bands I used is unfortunately approx 190mm, so new holes need to be drilled
- The M6 screws I had were too short, so I turned the wall band with the slotted area towards the back of the TV
- Take a look at the layout of the back of the tv. There are sections that's more sunken and other areas that are raised. The latter is the problem. To prevent re-cutting, keep this in mind. (see photo below)
- Also, cut the bands shorter than the tv, especially when using MDF. The speaker can rest against the tv bezel
- Lastly, for the tweeters' directional sound, I've re-used common rubber door stops to raise the back of the speaker (instead of the front as with my previous plasma stand)

I hope this helps someone!

Any idea of the weight limit?

The VESA mount will (at least) support your tv's weight, since it's used for wall mounting

My wife covered 2 bricks for me in black cloth. Exact same height as my Kef centre. Nice and stable with the plasma on top

Very nice :thumbs:
I like what some of the members on avsforum did with the supporting rod at the rear of the shelf to limit the stress on the tv and the bracket.

This is an awesome idea, I am considering this method, but my tv is wall mounted. So my idea is to extend the wall bracket to the top of the tv to support the center speaker.

Isn't it a bit too high? I mean sound wise, doesn't the imaging sound too high above the image/video?

It does look neat though

Thanks.

I've angled the speaker downwards to my main listening position, and it is projecting to approximately ear height and not playing overhead. IMO it doesn't sound bad, but then again I'm no audiophile

Hey all, kinda new to the conversation and to this forum. I might be a little late with a response regarding the placememt of the centre speaker and I too have had endless problems mounting it, top, bottom on its on own stand then off the stand and back on top of the tv then right back to placing under. So I got rid of my polk centre cs300 and replaced it with a floor standing speaker which is identical to my front main speakers. What a difference its made because all speakers sound and look the same. Have to get used to seeing a floor standing speaker as a centre though, but once u get passed that u really start to enjoy it. Take my advice and if u are able to get a third speaker for your fronts, take it. No screwing into the wall and mounting and damaging your wall. :2thumbs:

Thanks for the great idea. Any vibrations issues? The back panels are usually thin and flimsy.

No, there is no vibrations.

Also, keep in mind that the vesa mounting is used for wall-mounting. Thus, it's not flimsy as it's made to carry atleast the tv's own weight.

I have the same wharfdales i think, whats your thoughts on them?

Sorry, saw you post only now.

They are a bit power hungry (IMO), as I need to have my Onkyo 828 on 50 (relative volume?) for normal stereo video watching. I use them only for TV & movies and I'm really happy with them. They are nice and bassy, but the extra sub-woofer helps with giving movies that extra punch.

Music wise they sound very tinny ("blikkerig") when compared to my NAD/Technics stereo setup.

I have very limited exposure to other speakers, but for the price I can't fault them.

We bought 2 sets at the time, with 4 Wharfedale Diamond 9.1, me thinks. I was fortunate enough to swap my Diamonds for my brother's Obsidian surrounds, and I'm sort-off in process to change over to 7.1.

What's your take on them?

pretty much the same as yours  :giggle:
currently using it in 3.1 configuration till i can get my wiring done in the ceiling for the rears.
Managed to pick up a pair of wharfedale dfs bipoles as well, so hoping to get 7.1 goodness too.
