DIY flush mount speakers

[Soundman2020]

Just wondering how it's progressing, Eric? Any advances?

Hi Stuart!

I hurt my back putting up that temporary cloud (I am completely recovered now!) so that slowed me down a little. I did add some trapping in those corners and it made a small difference but not more than a couple of dB, but that was about it. Work picked up a little and I have been traveling around the country for competitions. The bright side is that one of the divers I coach won a Jr. National Championship.

I have about a two week break before I'm going to be on the road again for a month.

I still kind of stumped about that dip at 80Hz, I think I'm going to let that problem sit for a while.

I need to finish the speakers, I'm still running them on the prototype crossovers with electrolytic instead of poly capacitors. I need to improve the layout so I can mount them to the speakers instead of running the wires out the port! The speakers have no fill in them, and I also need to stain them.

Then mounting the speakers. Right now they are 2 x 4 "stands" with wood jammed between the wall and the speaker to fill up the gap.

Wow! Sorry to hear about your back, Eric. But glad it's better, and hoping it STAYS better!

It looks like I forgot to comment on this:

I rigged up a cloud. with 3/4" mdf and a 4" 2'x4' panel of 703.

I'm assuming green is before and red is after? Or is it the other way around?

Didn't get any change at 80hz.

What you show in the photo might not be big enough to do the job. You'd need a cloud that is much wider than that, extending out at least as far as the axis of each speaker. Take a look at the ones on Studio Three to see just how big they are.

So I decided to use my rig to fill the upper corner with 8" of 703.

Red is before and mustard is after?

Then mounting the speakers. Right now they are 2 x 4 "stands" with wood jammed between the wall and the speaker to fill up the gap.

If you are interested, I have developed a good method for doing that. It's a lot of work, and needs some precision workmanship, but I reckon that's right up your street, form the fantastic job you did so far! PM me if you want.

Red is before, green after.

Yes

Back from vacation and back to work.

Here is the more organized crossover fitted into the speaker.

Here is the speaker with the walls lined with 703. Before it was unlined, just wood and sound great, will it be better now?

Just need to put the bezels on.

I noticed that the back of your reflex tubes seem to be embedded in 703! I suspect that would dampen the tube resonance, and lower the Q. Is that what you wanted? A little less pronounced low-end extension, from the reflex ports?

I actually trimmed that out after that picture was taken.

I have been making slow progress and I will be updating with more pictures in the next couple of weeks. Hopefully the ones that will call the studio finished!

Ahhhh! I figured you wouldn't make a mistake like that! So either it was deliberate, or you fixed it before you put the front on...

Hopefully the ones that will call the studio finished!

Cool! I can't wait to add your thread to the "completed studios" list, right at the top, where it belongs!

Here is the planned set up for the monitor

The desk is made of salvaged plywood and the legs are cut from an oak beam from and old barn.

Man, that place looks awesome! Congrats, Eric!

And as promised, you are now at the top of the list of completed studios!

Any chance you could do a final REW test, and update the graphs? Or just send me the MDAT file if you don't have time to do the graphs, and I'll do some for you.

Amazing job you did there.

Thanks Stuart! The question is whether it will truly ever be done! I have been doing some of my own work in it and it is pretty easy. I still have some wiring to do outside of the walls to clean up a lot of the connections. Yesterday I soldered up this snake to replace 20 cables that are plugged into the wall.

In two weeks the first band is supposed to be coming in.

I should be able to post the measurements soon.
