A 3 way 99db multi configurable SEOS design - Page 7

post #181 of 702
Tux ,
I am just finishing up my first diy sub build this week and would like to start on your tux 99 before Dec 1st. Do you think it will be ready to order by then ?rolleyes.gif

I think so. Erich really is the guy to ask. The SEOS 10 way delayed. But I think its supposed to be here quite soon.

In the meantime you can build the box and preorder the SEOS 10. If you want to start building and would like details, just ask.

Yeah sure send the details for the dual woofer. Can I make the ports round cuz I don't like the triangle one's , and if so I will need the size. I will be making l , c , r so need the horizontal center. The picture looks like all the speakers are not flush mount which is easier except for waveguide ? I'm going to use mdf with fancy veneer. biggrin.gif

Ill get my notes tomorrow and post them.

Round is fine. I just didnt have the right ports kicking around.

The photos make it look worse than it is. I did flush mount them, but the soft ring around the woofer is proud, and the waveguide sits a little proud as well. And being that it was a test cab I just free hand routed, so not a tight fit. However you could surface mount if you want. Nothing wrong with that.

I'd like to start building mine too...any updates?

Sorry guys. Got sent out of town for work. Should be back on Friday.

The waveguides are suppose to be done around the 18th of this month. Then packaged and shipped here. I'm going to try to get a small box shipped here quickly so I can start getting flat packs made up and test fitted with components.

@Sibuna

What are you going to do with your Tempests if you get tux 1099? Use as surrounds?

Lucky you. I'm actually running out of rooms where I can put speakers! wink.gif

RE: A 3 way 99db multi configurable SEOS design

I was about to pull the trigger on a pair of sentinels. However, I think I will wait and get three of these.

What surrounds would you match these with?

Well since I did not revive this thread...I'd like to ask for the dimensions again so I can build my boxes.
Can we please get these?

thanks

Hey frenetia. Ya sorry for the delay. I have been working out of town way more than I thought and haven't been on my speaker computer for weeks. I post from my phone. Sorry. Hopefully ill be back sometime next week. I'm tired of travel. Gives me lots of time to cruise avsdorum though wink.gif

Sslvl2pwnd, I'd use the TM of these that I just finished up. Should have the details soon.
post #197 of 702
Tux,

I'm now debating whether I should get the fusion-15 instead.
Anything I should know between the 2? frown.gif

Would that be a mistake?

thanks
post #198 of 702
Thread Starter 
It's really a matter of choice and needs. It's not a mistake. The fusions 15 goes lower. Holds directivity a little lower. The tux10-99 has better vertical control, higher sensitivity, and can be used horizontally. Also has a small TM available that matches for surrounds and the 10-97 single woofer version. So its got the whole set aspect if you wanted to expand.

PS. Ill be posting some of the construction details later today. I still am not sure when these will be totally available due to the waveguide delays.
post #199 of 702
Tux,

Would it be ridiculous for me to built fusion 15s or tempests and then use the Tux1099 for a horizontal center if I wanted to be able to have the little more low end ability for 2 channel music, even if I wanted to run without the subs, but then for movies cross everything at 80?
post #200 of 702
Thread Starter 
Not really. But you wouldn't have matching LCR which a lot of people put lots of importance on. But if you really want to turn off the subs for music, the Fusion 15 would have more bass. I just use subs personally so I don't think about it myself.
post #201 of 702
a 40 degree wide field of fire is fairly narrow for center channel.

maybe a little more explanation on how that works would be a good idea.

Sorry, LTD02, I'm not sure what you're refering to? The woofers or the mids. The mids are wider than 40 degrees. The woofers are narrow true. When placed vertically though, the polar I posted doesn't apply unless thinking about the vertical window. So for left and right speakers, there's a wider horizontal window. And for the center channel, I think 40 degrees is ok. Assuming that's what you meant by this?
post #203 of 702
this was the guy that i was referring to.

my mistake. i was thinking that would be the l/r side as well. not the case. i'll modify my post.

post #204 of 702

Ok I got you now. You're right that it's a narrow window. Basically, it comes down to comparing against the competition. It's really hard to do a high output horizontal center channel. I've put up that particular circle polar for good reason. If I had gone with a smaller speaker like a 1inch dome over a 3" mid with 7" flanking woofers crossed at 600hz, the window width would be much wider. But the output would be much much lower. So then I could have crossed lower. But this is really difficult to do with a passive cross over. It sounds like a simple task, but it's not. So in the end, a compromise is made. This speaker was a real juggling act. Narrower mid and SEOS 8, less midrange output. Was hard enough finding the right mids. Bigger mids, taller speaker that doesn't fit under someone's TV. Smaller woofers, less sensitivity, or less bass. On and on. Was a real head scratcher, which made for a very fun design.

Thankfully there's a few things going for me. The woofers will end up a little closer than tested. So that will widen the window. The other is that center speakers are usually far away from sidewalls, so it's the listening axis that matters most. In this case, if you listening axis is 35 degrees, you're in a very bad place. But I think 20 degrees either side is being fair. From 10 feet back, that's 3.6 feet on either side. The final product will be more like 4 feet. So that's an 8 foot wide listening spot. Further back is even wider. For instance, 15 feet would be at least 11 feet wide. And I'm playing it safe at 20 degrees side to side.

The other option would be to use the active XO version for the woofer to mid XO, that widens the window a whole bunch.

For movies exact matching of lcr is not critical in my opinion . I have watched a over a thousand movies on a home theater and never had perfectly matched speakers . I always have had lcr. Speakers from the same brand with similar drivers. I wouldn't have a seos center with dome fronts.. I know some people are adamant about this but not.me . Only.maybe twice in all those movies have I ever heard a panning scene that was off. If your listening to 5.1 music then that's different .

You should be plenty fine then. I agree it doesn't happen often. But when the panning does sound different I personally am very distracted by it.

Enjoy the Fusion 15s. I think they look awesome. Would love to hear a pair one day.

Ok I'm finally back and settled in. I've been run off my feet lately and looking forward to this weekend. Kind of an interesting thing for work, a town I live near has underground mines all over the place. One of them opened up under a fairly major road near downtown. It was a truck route. So I've been buried deep in that project trying to solve the problem. Trucks were driver over a 20x20 area of soil only 4 feet thick with absolutely nothing below them. We discovered it below it was to late thankfully.

Ok. If you start to build these before Erich releases the flat pack, this is what you'll need to know.

Width = 12"
Depth = Can be what ever you want.
Height = This can also be what ever you want, except if you want Erich's baffle. I'm not sure he's landed on a final baffle height, but 36" would be about a minimum.

Ok, you'll need a midrange chamber for the mids. They can share the space. They are sealed, and should have 10L. If you need to build it with less, that would be fine, but bigger is better to keep internal reflection away. Provide ample damping material. I'd suggest a minimum of 10.5" wide (internal), 6" tall, and 10.5" deep or what ever depth you choose. That's 8L. For simplicity, the waveguide could share this space and allow more room.

The woofers can share a space or not. If they are in separate spaces, two ports each, kind of like I did:

25L (about 1cuft). Two ROUND ports. Each are 1.75" diameter and 2" long. The box should be amply stuff, even if it mean blocking the ports a little bit. The upper impedance peak needs to be knocked down for the XO to work nicely. So don't be afraid to stuff it up nicely.

If a shared woofer space with only two ports (not what I did):

50L or 2 cuft. Two ROUND ports. Each are 3" diameter and 2.5" long. Same box stuffing.

Brace it every 8" with dowels is my preference. You can improvise here though.

All your driver cut outs and things should be done when you have the parts in hand. However, for basic planning, the SEOS 10 and mids take up about 11" width and height. The woofers are about 10.5" overall. But make sure it all fits on the baffle properly before hacking it up. Flush mounting isn't a bad thing, but be consistent. Either flush them all, or surface them all. Flushing the woofers doesn't include the foam ring. That would put the woofer much to deep, unless the baffle was 1.5" thick.

Hope that helps people plan a little bit. In the mean time: ERICH, HURRY UP biggrin.gif
post #208 of 702
Thanks for the info Tux...I will wait till erich makes a flatpack and order for a LCR system.

Looking forward to trying these.
post #209 of 702
I'm going to make the alpha minion for rears first and then in the new year three of the tux. By then Erich for sure will have assembly crossovers .... I hope tongue.gif
post #210 of 702
Any updates on an ETA on when these will be fully available?
Thanks
