Hey guys...we need a little rallying here... - Page 237

Is there an issue with turning the tempests into towers? Or any of the seos designs for that matter? I guess my real question is: does extending the baffle affect the woofer's response? If for example, I changed the interior volume by .5 feet, would that necessitate a crossover adjustment?

Thanks in advance for the education!

No problem. It'll only change the port tuning. If going sealed, even less of a problem.

To get the tuning back to normal, you can make a false bottom, or fill the cab with something, or live with the peaky bass, or retune it.

Earth to Erich, you still with us? I sent a couple PM's in the last couple weeks, but haven't heard back. Swamped?

I know he is swamped for sure right now with all the sub flatpacks, etc. in addition to the regular stuff. He said he was going to need a few days to catch up, so I'm sure he'll pop up soon.

I was hoping he'd do a dual opposed flat pack for the 18's, but doesn't look like it. Excellent job with the TDM12 Baffles for sure.

Where is this info at?
Thanks
Chris

It's not posted. You have to ask Erich directly. Mike from AVS has a thread where both of our builds are located. You can see what they look like.

I think quite a few folks would like some of those. For $5-600 you can have dual Daytons or SIs with an AIY encosure and basically smoke most commercial offerings of three or more times the price. I will say though, if anyone is holding off on DIY cause of tools etc, and thinks they will do more than one build, it's worth it to buy a table saw and router to just build them at home if you can. It just gives you so much freedom on what builds and experiments you can do.

Then all you need to do is buy 4 of them and you're golden.

4 of what, the subs???

Absofreakinglutely

I have 16 of the Daytons sittin in my house, just waiting for the theater room to get done...it's killing me. I actually built a couple of single test enclosures when I first got them, just to try out and I have them in my temp setup now just for grins.

16... mother! That's insane and I love it. What's the plan?

The room is going to lay out somewhere between 7500 and 8000ft3 so I need lots o bass

I have a speaker thread...the SEOSR thread in this section that will show the mains and surrounds being built...BMS coaxs with AE woofers.

I thought I heard him mention before that a dual opposed 18" would have to ship in 2 boxes so it would not be cost effective. It would have to be a pretty big box, minimum of 6cuft but a little bigger would be more optimal for the SI 18's.

My dual opposed SI 18" is 36"x 24" X24" and weighs around 80lbs without the subs in it already. Shipping would be costly, but a dual opposed 18" flat pack would be so worth it.

You could just attached two single woofer cabs together. Might need long bar clamps to do it, but doable. I suppose you might see the seam.

I would have bitten. Just bought 4' SI box for now as I lack the tools/skills/will to build it. 

Hey maybe there'll be a "Single-to-Dual Conversion Box Kit" in the future? 

I am certainly swamped with emails.

I have a design for dual opposed 18" Daytons but I'm not sure there's enough interest to get them cut in a decent number. The CNC company could do it next week, or the week after. Each box uses about 1.5 sheets, so they'd have to ship in 2 boxes. But the last run of sub boxes was around $15k, and I also had to pay for the pallet of waveguides and horns from Poland which was around the same amount, not counting shipping.

The past subwoofer flat packs showed me that I need to hire some part time help. It was just too much for one person to keep up with. As of yesterday I think I'm caught up to about 4-5 days out on orders, so that's not too bad. But as news of all this spreads to other sites, those guys have no idea that I'm doing this by myself. There's nothing like slinging 40 - 70lb boxes around all day and then having some people aggravated that they ordered something 3 days ago and can't understand why it hasn't shipped yet. It doesn't really bother me or anything like that, but I wish they would read the home page prior to ordering.


A dual opposed box would be cheaper to ship than two single boxes, because it's 2 shipping packages either way. But of course the dual opposed wouldn't weigh 120lbs.

If there was demand, I'd do it. But it's probably not a good idea to turn this thread into another subwoofer box thread trying to keep up with who would be interested.

I'm ready to take this SEOS stuff to the next level and want to know if anyone is interested in helping with a Kick Starter project. I've been saving my money to get another size done in plastic. But I'm thinking about setting up a Kickstarter project to get more than one done at the same time. I stink at writing and trying to get my point across. So if anyone thinks it's a good idea, or wants to help write something up, I'm ready to roll with it.

I recall Erich had a good reason why it would have to wait but I don't remember exactly what that was.

I wish I could buy all my builds via a flat pack from Erich, I could then re-claim part of my garage by selling my table saw and a few more tools. I built a couple of his flat packs and wow do they make life more simple, I want my life to be more simple

Edit: Erich has just responded a few minutes before me so disregard everything I just said

We all just need a little patience Erich, but a lot of us really appreciate what your doing. Your doing the work of 10 men but some people expect 20, you can't please everyone but I am sure most are really thankful for all you have done, at least they should be.

I was mostly worried about shipping costs and how I would package it all up.....and the amount of time needed to do that. But I did find a shipping box that's 36" x 24" x 4" that could hold the top, bottom, and sides. Then the 4 baffle pieces, and 2-3 braces could fit in another box. Doing it like that is a possibility. Plus, I'm probably going to hire someone here shortly.

I think my box idea was 22" x 22" x 32" or so. That's a 7.4 gross volume, coming in a bit over 7 cuft net. It could also be used as a very large ported enclosure by simply changing the front and back. It might have been 23" x 23" x 30" which would net over to 7.25, or maybe 6.5cuft ported with some big ports.



I know this is hard to believe, but in the past 2.5 - 3 weeks I've taken over 4 tons of packages to FedEx.

Carrying all that stuff around you must be yoked like Mr Olympia

I can just see it now, in a few months the new workout craze won't be P90X or Insanity, it will be the Insane Flat Pack Workout, people will pay you Erich to pack up flat packs

they must either love you or hate you

prob both

I can't thank you enough for the baffles, waveguides, and drivers. Looking forward to starting on my SEOS towers in the next few weeks.

Do yourself a small favor - add a note about 3 weeks to ship on the order/payment page. If they ship in 1-2, you are a hero.

Better yet... why are you taking all that stuff to fedex yourself? With that volume, they will pick it up for free or a single pickup fee .... they are constantly calling me trying to incentivize me to ship more with them including offering label producing stuff, free scales, and offering pickup services for packages in addition to other volume based pricing incentives....

It just seems like it should be pretty easy to arrange pickup and save you time, your back muscles hehe, and wear, tear, and gas on your vehicle making all the trips....

I realize they can do that. But I'm in and out all day long. I can't be here waiting for them to show up at a certain time every day because I might not even be here.

You can schedule a specific day and/or time of day.... unlike freight company truckers, the fedex drivers were prompt the times I have had them come out for a scheduled pickup time...

Its nice to do things on your schedule and not have to wait on someone else.... I like to do the same 99% of the time... but there are limits....
