what size hole is needed for mounting?

The magnet (as well the tweeter's body) is about 2" 3/4 in size(70mm). You'll need to cut two little pieces for the contacts as they come out about 1/4 from the magnet. The bezel is about 1'' more so it will cover the hole nicely. I wouldn't recommend a 3"1/4 hole to fit the contacts as that's the size where the screwing holes are.

The hole size can be measured but the way the speaker is made, there is a slight flange on the outside of the magnet at the bottom that is the maximum hole size. If it is exceeded too much by cutting, the speaker will not fit snug and the screw holes for mounting could easily be compromised so you have no place to screw the speaker in. These are heavy speakers so it is best to use all three holes. So trial and error is recommended.

The hole size is not exact since you have to make room for the terminal connections on each side to go through. Size is according to the thickness of the mounting surface due to the two terminal connections on each side. The cardboard frame from the box shipping hole is too big. Trial and error on an unwanted material of same thickness as your mounting board is recommended.

It's about 3.250 x 1.750 oval shaped w\ mounting holes about 1.875 inches apart and centered equidirectionally. I don't know what size the mounting holes are but I used a #12 screw to attach it.

Mounting bracket can accommodate many different dimensions. I used 3 7/8" by 2 1/2". You can also go as large as 5" x 5". Some holes are slotted so you can use dimensions in between the 2 sets of dimensions I listed here. You can always drill a new hole or use a rat tail file to enlarge a hole or slot. Best of luck. We like the goal.

unsure, you need to know how wide the mounting bracket is. that will be the problem

I believe the hole was 18" diameter. You can download the installation manual if you go onto their website and it will provide the installation instructions.

Here is a link to the install instructions. Looks like 2 5/8" Diameter hole http://assets.bluesea.com/files/resources/instructions/6007_web_version.pdf

I'ts been mounted for a while. I don't know the dimensions but I remember that I was able to use 2 of the 3 holes from the previous obsolete Suncast unit it replaced.

I mounted mine in a 5 1/4" rail, but the minimum you could use is 3 1/2" due to the lenght where the rings goes. Hope this information could be helpful.

The mounting plate is 10-5/8" square overall. The bolt holes are 4-1/8" from center to center.

The dimensions of the mounting hole should be 1.8 x 1.0 with a depth clearance of 0.7 inches. Two friction mounting tabs are on each long side. These may require some shaving of the mounting hole for a fit. The short dimension is flush (unlike it appears to be in the photo).The integral faceplate measures 1.9 x 1.09 inches and is about 0.09 inches thick.Hope this helps.

The holes are right about 1/4" in diameter. I used torq headed (star) deck screws, screwed into a stud and they are very sturdy. Hope this helps.

Not exact, but likely no more than 2 inches - or custom mounting bracket will be needed.

Angela, it won't fit without some more cutting. The exact hole size that they'll drop into for surface mounting is 4-11/16".

Mounting holes are approximately located at 0", 2", 19.5", and 22". To make it mount securley to the wall, I did not utilize the plastic anchors unless it happened to be a stud. I utilized toggle bolts for the mounts where there was no stud.It should work for your application.

If you use the the lag screw, it would make about a 3/8" diameter hole. I didn't mount mine to the wall. It works fine for me free standing.

It has 6 screw holes and fit the original mount location perfectly. I can measure the hole diameter tonight if you need it.

the holes are standard 3 and 4 inches apart. I only have a 19" with mine and its perfect! I agree that this mount is heavy duty, i even had trouble mounting into a stud because the screws are that good! (and not crappy like a few other mounts I've purchased)
