The plastic case was laser cut. The direction were fantastic and it was super easy to put together. It's a Rasberri pi and an Arduino to control fermentation temperature.

Something like that was what I had in mind. I really think it is a classy look how some tube amps have a lot of the components exposed, but very cleanly assembled.

The way that case fits together is great, but I'm definitely not one that has mastered the soldering skill and I'm afraid my crossovers wouldn't do a case like that justice. I know there are a few on here that could make it look amazing.

Couple more examples of exposed and/or external crossovers. There's plenty out there if you look around a bit.

I like external crossovers. They just seem cooler. And easier to upgrade or tweak later.

Why build a crossover when you can just go fully active! Lol, I wish I could, I just don't know how to set it up.
Ugh, still waiting to hear back on selling all my speakers so I can pick up 2 Tux-1099s. It's traumatizing, I just want to hear the magic words "Yes, I'll buy all of your speakers, and EVEN the subwoofer too."

I noticed the Karma-10s are taken down. That's a shame, now that I understand EricH's idea behind them, I've recommended them to countless numbers of people across other forums. I hope he keeps the Karma line, great for the other forums I go to where people aren't necessarily enthusiasts, but still should be able to experience the SEOS design and they generally want to hop in as cheap as possible. Better this than the BOSE speakers that people were recommending...

Hey Erich, Parts-Express has some buyouts on 15" woofs, for $50, and $65.

Do you think Cheap Thrills II's might be in the works? For you guys wanting a Karma 15, this might be your ticket: Original Cheap Thrills thread

The new Fusion-15 hasn't been posted yet. There were some very slight tweaks that the designer wanted to make before it was 100% done.

I got pictures of the new 8" dual woofer models last weekend, but still haven't had time to get them posted. Packing up the 1099's kept me busy.

Teaser photos.....







There is another one, but I'll wait to post that photo. You might be able to figure it out though.

I've seen those, but they don't have enough to justify a design. Under 100 pieces for each one.

If one of those woofers is good, people will start buying and they wouldn't last very long.

I'm not a numbers guy, but what I was wondering is if one of the buyout 15" woofs would simply "drop in" in place of the Celestion?

I was just curious. It's probably not worth spending a lot of time wondering about.

Unfortunately the chance for that to work would be very slim. The past Celestion buy out was kind of an unusual woofer.

The old Fusion 15" was 2.5 cubic ft. I hope the new one is of similar size?

Any preliminary specs on these?

And I pick the top design.
---
On the Alpha, it seems 3 way high end designs (That can be converted to center channels) make the most sense for the "high end" line. You already have Fusion, Karma (Lowest Price Point Possible while retaining your quality level with simple crossover), and Alpha feels like it should be differentiated from the Fusion line.
2 way speakers with no sub/center channel doesn't seem like that many people here are running systems like that (most posts here are running surround sound usually). 3 way high end drivers seems the best way to separate the 3 lines so they all have their own purpose.

That's sort of the way I was leaning on the Alphas. But possibly not using expensive $500 woofers in the bottom. I was debating which way it should go a few pages back, but after lots of thinking, 3 way designs that can be converted to center channels fairly easy seemed like the best idea for now.

Woah.... Expensive man, not break the bank! Happy to hear that. They'll be using the new Compression Driver then?

Does anyone know the ports that Erich uses in the Tempest kit?

I like the look and thinking of using them in my TD12M/SEOS build.

Is it this one?

We might have an interesting opportunity for some high end, high output speakers but I'm curious if there's enough demand to move forward.

When the SEOS prototypes were done a couple years ago, I sent out a decent number of emails to people/companies that I thought could design some really nice speakers. Some people replied back letting me know that they were too busy at the time, but would consider it later.


About a month or so ago I was in contact with one of those companies and they agreed to work on a nice design. This would be an extremely high output 3 way speaker. Could be used for left, right, and center channels. They could easily be used full range and handle over 1000 watts each. But they'd be quite efficient, so even low powered amps would be fine. It would use custom 12" monster woofers, B&C midranges, etc.

While talking about the design, there was some discussion about it being a 100% completed speaker which would be pretty expensive. When I added up the parts, it was over $600, but under $1000 for components per speaker (I don't want to give exact amounts right now). I don't know if the completed speaker would happen or not, but if it did, do you think there should possibly be a limited run of kits first so that the DIY guys can get them for much cheaper than a completed speaker price?

We've talked about wanting a higher end, more expensive SEOS speaker. But when it comes down to it, I'm just not sure how much demand there really is and I'm a little hesitant to move forward with it. I don't know how all of this would work out yet, or if a set number of kits could even be made available first, but figured I should mention it here. Obviously I can go into more details later or start a new thread to go through the design ideas.

Would need to know size . why not have a target number of kits to make it worthwhile. Say its 10 to 15. If people put 1/2 down and you reach your goal then move forward. If only 3-4 people put cash down then just refund them and cancel. I wouldn't move forward without at least 10 people putting money down. You and me both know people say there going to buy, email, etc and then change there mind.

I can say for myself that I think this is the right move to make the most of the SEOS, but I can tell you unequivocally that I won't be buying any - neither kit nor finished speaker. I'm sure there is some market for it, it's just not me. I share your concern that the market is small, but if this particular designer/builder sees it as marketable, I'm very interested in seeing what they do.

Completed Speaker would definitely be harder to do and more expensive which I think would push more people away. If you wanted to do a completed speaker we'd have to get much more than just the people on this forum to purchase and that'd mean a lot of "advertising". Not something I feel is the strong point of some people on here =D.
Limited Run of the first kits would be your best bet just to test the waters. If you could get just ONE speaker completed and tested though (even if it's not the exact speaker but just close enough), then give us an idea of performance/cost, we could get a bunch of people to put money down first. If not enough people put money down first, you cancel it. But if you get enough, you move forward.

I think you'd be better off finishing up the Maximus-15 build and linking the parts/crossover though and just offering a baffle. Probably much easier, less time consuming, and less of an upfront cost as you'd only have to get some baffles for those kits.

We could obviously talk about the speaker size if there seemed to be enough interest. It would be a bit bigger than the 1099.

I've already seen the custom woofer samples and they are mean. No problem for the speaker doing full range, or tuned higher for serious midbass, or sealed to roll off around 80hz. Speaker sensitivity would be around 100db. But they could be used sealed in smaller boxes too. My thoughts were ported left and right speakers, sealed center that could still do 80hz.

Edit: Any chance there will ever be a prepayment method for people waiting on kits? Like if you're waiting on a Tux-1099 to be released any chance we'll one day just be able to prepay and then when the kit is released we'd get it?
I didn't say I'd be doing the completed speaker though.

If it was a completed speaker, I was just wondering if it made sense for me to try and get a small run of kits made up for people on this site.

As for the prepaying for out of stock kits, I'm not sure how that would work out for that model so I haven't given it much thought.

I'd be interested in 3 of something like this for LCR.

I'm still searching for my solution at this time, I love the 1099 but would prefer it just a tad more (like a 1299 or 1599)

$500 per kit is ok. $600 too. $1000 kinda getting crazy though... IMO.
