I'd love to do some sono based subs for the ease of construction, but they don't fit into my room design well. The PVC you have will be excellent.

Not as heavy as the box I would have built, but way stiffer! The piece these came from was almost 11 feet tall! It took 3 of us to haul it out to get cut down.


The sub amp that comes with the Rythmik servo drivers JUST fits the diameter of the tube too!

May wrap the tubes in some mesa boogie guitar cabinet vinyl.

Those are nice... with that thickness.I betcha they cost an arm and leg.


You can paint them any color you want... or put a fabric around them.

$100 for all of it. That's 4 pieces of about 30" each.


Yes, if not vinyl, then they'll just get a textured black spray and be finished.

I've got a decent amount of that stuff at my shop in varying diameters. That stuff is nice and heavy!


I've read where some guys will take a finish nailer and shoot in a few nails through cardboard sonotube into the mdf end caps. Well, I wouldn't do it with the stuff you have unless you shoot the nails at least 1.5 inches away from the edges. It will crack believe it or not. If you go that route, the walls are thick enough to actually countersink some screws. That won't be a problem.


Post some progress photos of the sub when you get them!

My friend Terry covered his mains in vinyl and they look pretty good. There's a thin layer of foam under the vinyl.

Having seen plenty of mesa cabs, and heads around; and after seeing those photos of the nicely done job with vinyl makes me really want to see what you are gonna do with these. I can't wait to see pictures.

Wow, that's some nice pipe. What kind of "ringing" does it produce?

With both end caps fastened in place, it does not really ring much at all. If you rap the side of the tube there is a slight high freq, very short duration ringing sound, but it is WAY above the range that these will play in. If I find it is a problem, I will add some dynamat style damping sheets to the inside. Don't think it will be a problem though. Also, the inside will be stuffed pretty well with the Bonded Logic acoustical cotton anyway.


Made more progress yesterday. It sure takes longer to do some simple stuff than one could ever plan for. Picts don't look like much got done, but I was in the garage for nearly 6 hours yesterday working on these tubes.


First pict shows that the pipe is not perfectly round. I have no previous experience with pipe this large, so I'm not sure if this is common in larger sizes. Anything under 8" I've ever tried seemed to be perfectly round. Good thing I cut the baffle pieces oversized with the plan of using a flush cut router bit to get them smooth to the edge. So the outside baffle is now smooth, however, the inside backing is obviously off. Once final assembly happens, I will fill those gaps in with some silicon caulking. Front baffle is two layers of 18mm ply glued together, back is just one layer of 3/4" MDF.

Getting closer.....they officially inside the house! May have sound tonight.


Good news. The Bonded Logic completely killed the slight ringing. Completely dead enclosure now.

LOL, same here. I prefer the planning stage 10x more than the actual building stages, ha ha!

Nice work


What was your source for the Bonded Logic insulation?
