Howdy.  I am toying with the idea of adding a pair of 5DBs as front height "presence" speakers.  I currently have a Yamaha receiver, but thinking ahead to when I replace the Yamie with a dedicated pre-amp in a year or so, I imagine Pro Logic IIz will be all the rage.  Are there any pictures of the back of the 5DBs?  The pictures of the 5DB on this site confuse me a bit, as it appears the speakers are sort of hexagonal in shape.  Also, in the main picture of the 5DBs as viewed from the front, it shows the switch to toggle between dipole/bipole as being on the right side of the tweeter.  But in a close-up side-profile picture, it shows the switch as being to the left of the tweeter.  In any case, I'm trying to get an idea of the position of the mounting holes and wiring path in the back of the speaks.  Any pics?  Thanks.

Hey Nick,

It's more of a trapezoidal shape because the back of the speaker is flat.  Check it out:

 

 

 

Here's what it looks like mounted:

 

 

 

As for the switch, it's on the left hand side of the tweeter and the right hand face of the speaker for the right speaker and the reverse for the left speaker (right of the tweeter on the left hand face).  

 

Here's how the two mount plates hook together, small plate on the speaker, large plate on the wall:

Cool.  Thanks for the fast reply Jason.  With those two mount plates working together, is the speaker able to be flush against the wall, or is there a gap?  If there's a gap, how far does the back of the speaker poke out from the wall?

Regarding the shape, trapezoidal makes a lot more sense, and matches what I was thinking it should look like.  But, I still don't see the trapezoid shape in looking at the "official" pictures on the site.  Not sure if it's just the angle they were taken at or what.  Anyway, thanks again.

Most folks use the rubber bumpers that we send to protect the back of the speaker, which puts it about a 1/4" from the wall.

Great.  Thanks again Jason.  Very helpful.

Along the line of the mounting hardware...

Is there a way to wall mount these so as to attempt to isolate the wall from being directly vibrated by them?

I was thinking, some sort  or heavy, thick rubber (that will absorb vibrations in the wavelengths that would annoy neighbors) that you mount to the wall, and then mount the speaker to the rubber?

Thanks!

Part of the mounting bracket secures to the speaker itself and then "rests" on the matching wall attachment.  The speakers lean slightling downward after the attachment is made.  The only part of the speaker resting on your wall will be the bottom two rubber bumpers.  I can crank my system up pretty loud, and I feel little or no vibration on the wall.  Any size sub is more of a concern than surround speaker vibration, but then again, I do not live in an apartment.  Darn neighbors, ugh!

The 5DB doesn't really produce enough bass for it to be an issue, but as JoeZ mentioned you do have the rubber bumpers sitting between the speaker and the wall.

Is there any rubber on the wall attachment that gets rested on or the mating part on the back of the speaker?

How important is it to get the two speakers aligned in the same plane as the front speakers? I could mount them on the wall about 5-6 feet up (has to clear my aquarium), but there is a possibility that one will be 6-8" offset from the plane if not because of the odd shape of my apartment then because I'm only human and, well you know what Billy Joel says.

(You guys would be horrified if I posted my floor plan. I have a large living room/dining room/kitchen/entry foyer/hallway area of a very asymmetrical shape.)

Thanks!

The rubber bumpers are included with your 5DB and you manually attach them to the speaker itself (they have a sticky back). 

I think you may need to mock up a floor plan for us.  Not sure I fully picture "same plane as the front speakers"?

Yeah I'm not sure what you mean about by the same plane as the front speakers either, but if you mean that the distance between each set of speakers has to be the same, it doesn't.  Lots of folks have their surrounds spaced wider than their fronts.  You just want to sit as close as you can to the center of both sets so you are equidistant from left and right of each set of speakers.  You'll also want to place both 5DBs at the same height to get the proper surround effect.

NYC,

I think what your question on plane refers to positioning the 5DB at the same height as the front speakers?  If so, optimal placement for the 5DB is to the sides of your primary viewing position about 5-7 feet off the floor (they actually do a little better in a higher position than the normal positioning of about standing ear level for surrounds) as long as they are both at the same height.   So yes, even with your aquarium requiring 5-6 feet up, you should be good to go.

Hi again,

I think I was clearly unclear in my prior posting.

Imagine there is a TV screen that is perfectly vertically oriented. Let's call the up-down/side-to-side viewing panel of that TV screen (as most would be looking at it) is the "plane".

Then, the front speakers would be parallel to that plane as well. One wouldn't be 2 feet ahead of the TV and the other 2 feet behind.

So, that's the plane I'm talking about.

Presumably, the center channel would be in the same plane as well if it is aimed correctly.

I'm wondering if the 5DBs have to also be set up exactly in that same plane, or if there is wiggle room, and if so, how much?

Thanks!

If I understand what you are saying you are asking if the 5DBs should be directly to the sides of the fronts and center?

If that's the question, then the answer is absolutely not.  You want to place the DBs directly to the sides of your sitting position.  Any surround speaker you either want to place to the side of your listening position or behind you.

I conclude that I suck completely and should use the remainder of my 1000 words on a picture.

With that being viewed... How important is it that the two 5DBs be aligned with the viewing plane? What if they are off by a bit? I may have no choice due to concrete supporting pillars in my apartment to mount them perhaps 6-8" offset so they're not exactly aligned. I sit about 10.5 feet from the TV screen and they would probably be about a foot behind me.

Thanks again for trying to understand Mr. Incomprehensible In New York. :)
