I see you have the sealed version with the TD12 cutout too. Since they will be crossed at 80hz I could use either one.
Can anyone give me an Idea of what to expect with a 2 cuft flatpack 3 port vs sealed?

It's too bad this woofer isn't a little easier to get your hands on. It would be a good candidate for a micro surround, in a smaller box than the smallest waveguide speaker yet.

http://www.parts-express.com/pe/showdetl.cfm?partnumber=264-852

Reasonable price, quality sound, good sensitivity, and looks nice to boot.

Then again for whatever reason when I model it in Unibox it looks quite wonky.

Don't be so pessimistic! biggrin.gif There's no problem at all with the fit. I'm just saying it's closer to the waveguide and ports than the Delta Pro is.

Yes and like drywall mud, you slightly over fill and then sand smooth.

Sweet!
I am now optimistic about receiving an invoice in the next few weeks.biggrin.gif
Thank you Erich for your time and getting these custom baffles cut.
Without DIYSoundgroup I would not be doing this.smile.gif
Thanks again

I did miss those, thanks. However it would be nice if they were closer to 90 dB 1W/1M. I know, I want it all. The Aura NS6 is out of stock just about everywhere now, but that EAC midwoofer looks like an interesting option... until you realize someday that will be NLA as well.
post #7448 of 9844
Ya, they use the typical small midwoofer of 88db/w which ends up at like 85db.

What's the EAC midwoofer?

The tang band midwoofer you pointed out is really only good for 90db before BSC. So it'll end up around 87db for most I imagine. You might be able to find a few NS6 used. Even those were only a true 90db half space as well. And the few woofers that can get over the 90db mark have no bass. I'm somewhat pessimistic when looking at that spec. I look at the SPL at 150hz to tell what it's really made of. To get over 90db, make bass to 80hz sealed, and not go 8", will cost a bit. MTG90 is working with the TD6 right now. That might be a good one.

Hey Guys,

Well I've read http://audiokarma.org/forums/showthread.php?t=150939 eek.gif

And I've read http://techtalk.parts-express.com/showthread.php?215536-Flex-Your-PCD-Mettle smile.gif

And I've read http://www.avsforum.com/t/1291022/hey-guys-we-need-a-little-rallying-here Twice tongue.gif

and finally I ordered two ZEPHYR kits. I just have one question. I might want to pole mount the ZEPHYR. If I do, will I need to cut the middle port shorter? and if so will it affect my bass response?

Thanks guys for all the work put into this project smile.gif No way i could have ever afforded a system like this without all the help

I read the AudioKarma thread as it was happening, was an awesome time watching Zilch and the crew evolve the econowave from a waveguide adaptation of existing speaker into a standalone unit (with multiple variations). He who shall not be named in this thread and Zilch worked well totogether to develop the initial crossovers for the stand alone untis, Pete over at Part Express forum sure did flex his PCS muscle. Good days indeed!

Sorry, EAW.

Looks good on paper, at least. $40 each if you get 4 or more.

I'm thinking on ordering some Sentinels for LCR, but I has a question about the kits page.

It says on the last line, in speaker notes,:
"If you don't want to build your own enclosure, you can upgrade this kit to the complete flat pack. Obviously you need to assemble it, but that is pretty easy. There's an option for a sealed 2.5 cu ft enclosure."
... only there is no option listed, nor any matching flat pack on the site.
Still debating my decisions, but I just happened to catch it while getting dimensions to make some mockup boxes.

I've still not grasped the differences between the 12's, Deltalite II, Tempest and Zephyr. If used with a sub@80 crossover, would any me more accurate for mids than the other? AFAIK, the Tempest has the "mid kick", yet the zephyr has the "better" woofer (esp. for displacement).

Probbably not the best place to ask, but what is the difference between sealed, ported and slot ported for any of these?


Lastly, I've not kept up with the thread. What, if any, would be getting added to the site between now and a few months. I understand it's a busy time for landscapers, us surveyors have it just as rough, everyone want's it done by thursday smile.gif

"I've still not grasped the differences between the 12's, Deltalite II, Tempest and Zephyr."

i'll take a stab, though i'm not 100% on this. the designers may have additional and/or corrective info.

delta 12a and delta pro 12a have a little higher sensitivity than the 4012ho and the 2512.
the pro has more xmax than the 12a. not sure what the tuning is on the the 12a, but it probably hits xmax around 35 watts or so.
so if you are going to play LOUD, the pro 12a has an advantage. playing past xmax is common with all these drivers, so it simply means the pro will go louder for the same level of distortion.

the 4012ho was designed a little different. it has lower sensitivity in the mid-bass by about 2-3db, but it picks up more bass extension, so it will work with a lower crossover or in some applications without a sub at all. highest xmax of the four.

the 2512 has the best inductance control, which can be seen in the swing in the impedance plot. that along with its very soft suspension (high compliance) suggest that it likely has the clearest midrange of these four. it would work best sealed imho as it is down 3 right around 80hz in a medium size sealed cab.

i haven't seen any distortion measurements for any of them and eminence doesn't publish distortion, so as far as that goes, it is kind of flying blind.

not sure if there is a kit using the ae td12s. that would be a nice one to add. the other super-premium model might be the 18sound 12nmb420.

a comparison grid would really help for the kits.

I didn't do a lot of updating on the site because I was hoping to get a new website up and running by now. But time wise, things didn't work out. The person that was going to work on it got busy and wasn't able to finish it up.

I recently found someone else to work on the new site and it will start rolling again in a couple weeks. Basically it will list all the information on each speaker and just get things organized better. It's been very hard to do by myself.....as you can see. rolleyes.gif

The main things added to the current site over the next couple months will more flat packs, and more 'traditional' speaker kits like the Overnight Sensations. Completed crossovers are being worked on right now. I have a decent number of assembled flat packs, I just haven't listed them yet.

The goal in the next couple months will be to get things better organized and get type up some better descriptions, better photos, etc.

Late last night I worked on the SEOS-15 preorder page:

Dieing to complete my Fusion 10 Max fronts and 8 sides!

Really nervous about painting them. Going to be hard to do in a bedroom (damn renting!)

Has anyone used Acyril paints for a better finish without needing to use poly/lacquer?

I used duratex inside and it had zero odor.

If $30 6" woofers don't scare you, these woofers look promising and easy to work with....

I've actually worked with those and the 8". They're pretty decent. They would make a great woofer for the smaller speakers.

Erich,
I've been over at Audio Circle exclaiming the virtues of DIY Sound Group kits. http://www.audiocircle.com/index.php?topic=116568.msg1221934#new
It seems that the moderators over there are passively discouraging vendors that aren't site sponsors from getting any traction. If you want to have access to more potential customers for the Sound Group you might consider becoming an Audio Circle Site Sponsor. You mentioned that 1000 units is the minimum quantity for each plastic waveguide mold. This might be a way to have access to a fairly large audience of potential buyers.

If a site "requires" sponsorship to talk about a kit, that site can go f*ck itself. I wouldn't trust any opinion from people like that.

Selling on the forum would be another story, as that would require sponsorship.

They don't require sponsorship but I've noticed that my pumping of SEOS kits hasn't received the amount of feedback and discussion that I'd expect. If you noticed the last post, on the link above, brought up this point while hawking a small kit by a Site Sponsor.

Although AJ is pretty knowledgeable, he can be an ass at times and I wouldn't take what he says to heart.

Does anyone know how much it cost to become a sponsor on that site? I'm not sure who I would ask.

I think you join Audio Circle first then go here and follow the directions.http://www.audiocircle.com/index.php?action=about;area=industry-participant#joining
post #7466 of 9844
This site would be one to sponsor over one that hasn't even given your site a glance IMO.

Not sure the business end of doing something like that would be good, especially if you're just breaking even as is.

I'm almost done typing up the page for BWaslo's design using the 15" Celestion buy out woofer from Parts Express. I don't think it's possible to get any other speaker like this for that price. The Celestion just happens to be a really nice woofer. It plays loud and clean and has a very nice frequency response. Bill really nailed this one and kept prices low with the buy out woofer.

The entire speaker will be around $195 with the CNC cut front baffle. This one will be best split up in 2 orders so you can get the crossover parts and woofer from PE to get free shipping for that stuff, then I'll package up the remaining parts in a smaller box.

are there any known distortion measurements of the deltalite ii 2512 / seos12 / dna360 / bwaslo crossover combination anywhere?

grazie.

That Celestion buyout kit is a great price. There's no flat pack box to handle that size though for us shoddy woodworkers.

Erich,

This one sounds really good! Have there been any thoughts (advantages) of pairing it with the 15" waveguides?

(Also; did you get my mailing, check and SEOS 3D printed emblems?)
