If I'm converting right, this is a 6" woofer right? (I wish the US would just switch to metric for good.)
This would mean the possibility of an even smaller SEOS speaker... If that's the case, I'm in as well!

Its not about metric vs standard its that driver manufacturers don't all follow the same measuring standard. Do you measure the woofer from the outer frame across and label it as a 7 or 7.5" woofer or do you measure just the outer surround across and label it as a 6-6.5" woofer?

I've seen the Anarchy labled as 6, 6.5 and 7".

Ah ha! I've wondered myself how to measure them. Interesting, but not surprising that different manufacturers measure differently.

I know it's not a metric vs standard, it just it's one of those things that irks me. Life would be so much easier if we went metric. No more pounds force or pounds mass and especially no more fractions!

Any chance the 8ohm version would still be an option too? I've had enough requests for "can you use a different driver in the Ansonica, please?" that it would be nice to have the original - just can't argue with its performance, and nothing else really approaches its capabilities.

I'd really have liked a 12ohm version too. wink.gif

All that aside, awesome driver and good to hear it won't go away completely. I've pondered what it would take to make this happen myself but never got all the pieces together to even feel I could legitimately approach Kevin with the idea.

I don't get the coil change either. Seems more useful to keep it the same, and thus maintain a large existing base of 2- and 3- way designs, than to change the coil and make amps work harder to drive them in "tapped horn" bandpass boxes.
post #38 of 148
I can see the coil change being advantageous for a little more efficiency in his tapered horn enclosure and small 2 way designs.

8 Ohm probably wouldn't move as good as the 4 Ohm model at first. So if both will eventually be done, it makes sense to start with something new that will get the ball rolling faster. 4 Ohm makes sense for car audio guys, subwoofers, and MTM designs. I'm picturing double woofer designs to give that extra output everyone always wants. Towers, MTM, center channels, etc. Then also a waveguide set up with duals under a SEOS-12.

Even looking at it another way, repeating what might not have gone good in the past probably isn't the best thing to do now. Once we see how things go, we can check back in on the 8 Ohm model. But I have to pick one or the other, and it's not going to be a cheap choice either way. So the 4 Ohm seems to make the most sense to fit more needs right now.

Of course I'm not a speaker designer, so I'm open for suggestions. But keep in mind we didn't see a lot of different projects with the 8 Ohm model that's been around for 3 years. So does it make sense to continue down that road, or shoot for some MTM's that are closer to an 8 Ohm load.


Around here, most of us don't care about 4 ohm loads on our equipment. But that's not the case everywhere else.

I'm not sure that the 8-ohm-ness of the Anarchy was it's downfall; it was inconsistent availability from a company clearly having troubles and significantly fluctuating pricing. Shortly after diving on the Anarchy for the Ansonica, things changed and I almost abandoned it due to the troubles Kevin was having. I don't like making designs that are dead-end no-one-else-can-build-it. A lot of DIY folks have wandered away from AE despite their quality for similar reasons.

I'll disagree re: MTM, and point out that any existing designs out there will not work with a 4ohm variant - there aren't a lot, but there are some. This driver needs a low crossover point in a 2-way, and going 4ohm means no 2.5 way (which is where I landed for the Ansonica after toying with plain 2-way in the early stages.) The already low sensitivity will likely be hurt more in an MTM (or other 2/3-way). As it stands, excursion is crazy but still limits is raw SPL capabilities. Driving this down further won't help...

My guess is you'll be looking at car audio and people wanting to use this as a "sub" and probably some folks doing other designs, but I'm not convinced you'll see significantly more - though consistent availability could sure help.

That may be enough to justify the first build run and make something more of it...

Maybe a dual 6ohm VC version? smile.gif give us a 12/3ohm driver...

Anyhow, still thrilled to see a variation of this live on.
post #41 of 148
I don't really see the problem here. If the old design go away because of the coil change, new ones will come out. There aren't many anyways.

I think a 4 ohm coil is better for this type of driver. And for 2.5 way MTMs it'll be cheaper to use a cap to kill the 0.5 woofer rather than an inductor. Also the 4 ohm will appeal to the tapped horn and other applications like car audio.

I think its a plus.
post #42 of 148
Maybe its just me, but I'll be happy with whatever Eric decides to do.

I just appreciate this generally, regardless of whatever it turns out to be - specifically.

Seriously? Cheaper is what comes to mind?

If $40 for a reasonably low impedance coil (14ga air core) vs $15 for a cap (basic poly - may be less, I don't actually know what size is needed) is worth needing twice the amplifier for the same SPL output... but I digress. I'm not objecting to a 4ohm, I think 8ohm is tough to work with too due to the particularly low sensitivity. I'd go 4 and 12, and starting at 4 to get things moving still makes enough sense.

I think I'm just always frustrated with the "I want to use your design but with this change, can you tell me what to do" thing... I already get requests to use a different mid-woofer (it's not the same, but sure - designs with other drivers are possible... just not magically like seems expected) and I'm sure this will have people asking why I don't go buy a set to update my designs ...

Thanks Erich, regardless.
post #44 of 148
Erich, when will these be available, and, how many would I have to order to get some of the 8 Ohm version?

Heh, actually, I was measuring two different woofers and finding that, at least with my particular use/enclosure they actually could be swapped with no crossover changes:

The minimum order is quite a bit. Hundreds......and hundreds.


There's some possible good news though. The manufacturer may let me split it up and do both 4 ohm and 8 ohm with the same order. But doing this will likely require the minimum order to go up though. So if this is allowed, prepare for an epic pre-order like we did with the SEOS-12 to make this happen.

We might have to make a post on the car audio forums or something once we get moving with it. I can handle the original order if only a very few people did the pre-order. But to do both ohms, with a slight increase in the minimum order, might require a bit of help.
post #46 of 148
I'm excited to see what the designers come up with. Curious how they will compare with current designs.

I really like Kevin, he's a good guy. Shame what happened.
post #47 of 148
Fantastic to see these coming back out. I loved their initial design. Killer 7" midwoofer (that really does not do them justice to simply call them a "midwoofer", haha).

Ill preorder two 4ohm smile.gif

There is already talk of it on the Do It Yourself Mobile Audio (DIYMA) forum. smile.gif

I spoke again with the manufacturer about doing a run of both models. He's waiting on a reply to be 100% sure. I don't want to bug them about it too much, or they could just simply say 'sorry, we can't do that'. So let's just wait a few more days to see how it all works out.

My understanding is that the clearance price of $50 was pretty much about as low as they can go counting shipping and customs fees. When the manufacturer said raw materials went up, I didn't ask how much, but I'm hoping it's only 10% or less, which would put the woofers at $55. But then we have to add in Paypal fees (unless paid by check), and a shipping box. But I've got some free smaller shipping boxes that I've been collecting in my garage for quite some time. It's a mountain of double thick boxes.

Later down the road, there's going to be $5 added in that will go to orphans and/or children in foster care. But here's what my plan is:

For anyone preordering, they won't have to pay that $5. I'll pay that extra $5 donation myself to keep the prices low.......it's going to a good cause anyway. Once the woofers arrive and the preorder is over, we'll add in that donation amount for future pricing.

I'm gathering up some really neat give aways for the big preorder 'raffle'. smile.gif Prepare to see some crazy stuff.

Obviously I'll be getting the tapped horn boxes cut, maybe even some double wide units and take 2 woofers. Then we'll see who wants to design some MT's, MTM's, 2.5's, 3 ways, small subwoofer boxes, etc.....etc. Many designs will be coming.

Very glad to see these continuing on, and in 4 ohm. I had tried to arrange a group buy with Kevin for a 4 ohm model for the car audio market last year but we didn't get enough pre-orders to make it happen. I will probably put in a pre-order for these and see what happens, would love a set of these in my car.

How many preorders did you get?
post #53 of 148
Not sure, Kevin just had them order on the site like normal, he tracked all that. It was hard because it wasn't on a ton of forums and I don't think it got posted on any DIY home audio sites, you should be way more successful.
post #54 of 148
Erich,

It is great that you are going to pick these up and continue the line.

Do you know when you will get more flat packs in and how much they cost?
post #55 of 148

Big news: They've allowed for a split order. The minimum number is fairly high now, but we'll have either model to use, so it's worth doing.

Now no one can feel like they're missing out! biggrin.gif

"I think we should get the 8 Ohm"........no problem

"Nah, let's get the 4 Ohm".......no problem

I'm not sure when those flat packs will be ordered. I'll have to see how backed up the CNC guys are. The price was reasonable for the Baltic birch, but I can't recall the exact figure right now. I think they were around $70 with the packaging material. They'd likely be around $50 if it was mdf. But I'm not 100% sure on that.

Awesome, can't wait for the pre-order to open up!
post #58 of 148
Can someone suggest a plate amp to power one of these? One with a HPF would be preferred.
post #59 of 148
I absolutely love my single TH. But I would really be interested in a double wide. So the 8ohm version will still be in demand.
