Soundemons SEOS Fusion 12 Tempest LCR build thread

I'm starting a build currently for an LCR of SEOS Fusion 12 tempest. I've got all the parts currently just waiting on the binding posts and plates.


I'm actually going to update this one while in process, rather than finishing and posting everything after the fact.

The MDF has been cut and I've got the baffles glued up awaiting trim off. (pix to come)


My first question is about box stuffing / box lining. what have others done here? I just cant bear the thought of having bare walls in there!

I think we're the demons.

You don't need stuffing, just damping material.

I used pink fluffy fiberglass in my Tempest LCR. It's cheap and works well. I just used gloves when gluing them down with spray-on glue.

How thick is the fiberglass you were used to line your Tempests internal wall?

2 inches thick. I got a thicker roll (I forgot the R value) and pulled it apart. And used a throwaway pair of scissors from HF to trim it.

I used the Ultratouch denim insulation on a recent project. Much more expensive than fiberglass but that's only a few $ on a pair of speakers. One roll per cabinet should do it.

Good luck and rock on!

I built 3 Fusion 12 Tempests for my HT LCR. Details in my build thread.

The Vortex Theater Build

About halfway down.

I used 1.5" acoustic egg crate foam glued in with spray adhesive.

post some pics! What finish are you doing on them? Fiberglass/insulation is the best for speaker lining. I'm using Roxul safe'n'sound. It's not as easy to work with as foam or other "safer/nicer" materials but it has the best damping coefficients by far. Just glue it in with spray adhesive and I'm covering it with cheap speaker grill cloth.

Some initial pix: all table saw cuts are now done, baffles glued and routed for size


I included my sketch of my cutsheet to show how easily 3 speakers fit into 2 4x8 pieces of MDF. I had the guy at home depot cut 2 28" lengths off one piece and 2 26" pieces off the other one. then all the pieces fit with reasonable ease into the back seat of my Altima. (not a huge car) all pieces layed out on the cutsheet are oversized to allow room for error.


the baffles needed to be doubled up. I cut these pieces a little oversized on purpose, and made rough cuts with a jig saw for the cutouts, so the router didn't have to work as hard, and makes (a little) less dust.


the braces I had planned to cut them out rough with jig saw and then finish with router but quickly realized this was overkill. I just drilled out each corner and jigsaw'd the rest. the finish was no where near as rough as I had expected.


Box assembly is up next. Finish will be walnut veneer

Some decent progress to date. driver and wave guide inserts ... inserted.
osed screw ins for the woofer, and tap ins for the wave guide. but I don't tap them in with a hammer, they deform too easily. Instead, I draw them in with a screw and a washer from the opposite side:

Scalloped the back of the woofer cuttouts to let the woofers breathe a little easier.
proceeded to get the boxes started, one panel at a time for the first one, then realized that was ridiculous so did all 4 at once for the second one:

Did a mock-up to make sure my bracing didn't interfere with anything. Also a shot of how I layed out the back panel. Everything from the back is glued and screwed. everything else just glued. this keeps things nice and straight and parallel. I drilled the back on the drill press, and then clamp and ensure everything is lined up perfect, and then drill thru pilot holes into the lateral pieces.

Crossovers done and ready to go into the box. I tried something different this time, soldering speaker cable directly on to the crossovers. this just eliminates a screwdown or crimp-on junction. Its a bit of a pain because the joints with the speaker wire take a looong time to get hot enough to flow solder. I just played games on my ipod while I waited...

I do the same thing for my crossovers, if you have a powerful iron it just takes a second to heat up. Even with cheaper irons - make sure you melt some solder on the tip and then use the liquid solder to help transfer the heat to the wire, it shouldn't take that long, definitely not long enough to play a game while waiting! haha

Got the cabinets all lined and crossovers installed. Found a great deal on some 1.5" eggcrate acoustic foam so lined with that:

Particularly when using dark components and finishing in a dark finish, I hate that little peek of MDF yellow you can see at certain angles from the sidewalls of the mounting holes. So I spray these black, and masked off so there aren't heavy black areas where I'm trying to veneer

Making some good progress. Cabinets are all together, and done with final sand. I'm now in the process of prepping for veneer.
For veneer I do the iron on method, and with raw veneer. I get it in strips, which is harder to work with but a ton cheaper than buying the full sheets of paper backed stuff. (the glue for the veneer job cost more than the veneer itself)

Nice even layer of glue on the speakers, then you do the same on the veneer. rule of thumb is a little more on the speakers and a little less on the veneer, but the aim is a consistent even layer, and good full coverage. I aim to have a little more around the edges, and the most concentration in the corners. otherwise you end up with the most in the middle, and its most needed at the edges.

The strips of raw veneer I'm using, a progress pic, and one speaker fully veneered. this is before sand / patch / sand / stain / finish etc. just raw veneer.

Couple more shots - I use a polyurethane with stain mixed in, sand then poly, then sand with 320 grit, then poly, next is a rubdown with steel wool, one more coat of clear poly, another rubdown and final assembly! should be completely together and listening by this weekend. and then I can focus all my efforts on my Ghorn build!

Here they are completed! they sound excellent so far. Stil running them in a bit, but with movies these are amazing, clean and clear, lots of impact which is what I was looking for. for music so far they are very good. not quite as sweet and delicate as the statements, but that is definitely to be expected

The center is going to behave oddly on its side. You are going to get lobing toward a side seat (right side) Jeff designed the 99 Special to go with these if you are height limited for the center. I love my Tempests. Others may have other comments but you will get odd bounce off of the floor.

They look absolutely beautiful though.

Have you tried toeing in the speakers (aim left to far right seating position and right to far left seating position)? It should give a bigger sweet spot that way (and should keep less of the sound bouncing off the walls).

Also, can you keep the center vertical? The SEOS waveguide being vertical will lead to a small sweet spot.

Thanks for the comments so far guys! I am going to do some playing with the placement in the days and weeks to come, where you see them is right where they plonked down. so far with no adjustments, and in my crappy non-treated unfinished basement they sound great!


I will be seating the center vertically in the future. The screen will be getting shrunk a bit to make way for this. (I only use 5/8 of the screen area as it is - golden ratio seat distance to screen size this screen is way too big as it is)
