I'd like to build some speakers for use in an audio and home theater setup. I like the idea of the Pi 4 Stage Series, as I can upgrade to JBL drivers at a later time when funds allow. I do have a few questions before I proceed, thanks in advance for any help.

1.) I'd like to stand these on top of the storage cabinets I use to store my music/movies, but I'm not sure if they're too high. The cabinets are 26.5 inches high, and my listening position is 10 feet away on a couch. Also, do you think standing them on cabinets will cause vibrations or other issues? I've included the URL to the actual storage cabinets, if anyone is curious.

2.) How heavy are these, if build with MDF? I'd like to use the Pi4 Stage as a center channel, too, which means I'll need to mount on the ceiling or the wall behind the TV. Are these too heavy to mount? If not, can anyone recommend specific wall mounting brackets?

3.) I'm a complete newbie to building speakers, is there a resource online that someone recommends that covers, in detail with photos, how to build these? I'm talking more about the basic construction, and leaving the physical look (wood veneer, paint, etc) aside for the time being.

Basic box construction. What do you use to secure and seal the four sides, glue/sealant, screws, etc.

Bracing. Where are the braces mounted, how many, of what material, how are they installed (glue? screws?).

Installation of the driver. Do they have to be recessed, what tools are recommended, do you use a sealant, etc.

Installation of damping material. What kind, how much, etc?

As you can tell, I'm clueless about all this. I've actually read quite a bit in this forum the last few years, but many of you appear to have extensive experience, and tend to discuss design theory as opposed to the more elementary topics highlighted above.

Any help would be greatly appreciated.

Regards,
Steve

Stage four π speakers weight about 50 lbs, so wall mounting is fine. Just be sure to mount to a stud. Here are some photos of wall mounted Stage four π speakers:

When you get the plans, you'll see that cabinet construction is pretty basic. You can use butt joints, which are a simple as it gets. Just flat panels glued togther at the edges. No diagonal cuts, no dados. You will want a brace from front baffle to rear, in between the woofer and tweeter. You can also run one from side to side. Put R13 insulaton on the bottom, side and rear of the cabinet interior. That's all there is to it!

I like Wayne because he has lots of resources like this one (JBL) here.
Also, just look around on google under the name
"Rigging Speakers"
or
"Basic Principles for Suspending Loudspeaker Systems"

• Basic Principles for Suspending Loudspeaker Systems

"The FRi Series features internal heavy gauge steel
reinforcing brackets that are not only designed to provide
high safety factor support for the 3/8-16 forged eyebolt
rigging, but also to unitize the internal panels for each
enclosure. These corner braces are required to maintain
the structural integrity of the cabinet to performance levels
listed in this manual."

I would see under the names of DIY (speakers) and Enclosure Assembly.
If you use screws with glue is better but you will be much more tired from that. The white glue (carpenters glue) is the best one. It all depends if you use wood, particle board or plywood, MDF and also about it's thickness. MDF (and veneer) is very well accepted. YOU ALSO NEED GOOD LONG CLAMPS TO LET THE WOOD/GLUE DRY.
