I think the simplest would be, for european "customers", to ship by boat.
I was an exchange student in Montreal. When I moved back to France, I had about half a cubic meter of stuff. A friend moved too and he had lots of stuff, so we teamed up and shipped it by boat.
It's been a long time, but I seem to remember that shipping a cubic meter (the smallest size) of stuff from Montreal to France cost about $200 Canadian. Of course it took a month to arrive, but it was not that expensive as you can see.
There was a weight limit (pretty large) and the cubic meter could be made of several boxes. Unlike air mail, weight on a boat is much less an issue. Basically as long as a forklift can lift it, they don't care. And since the waveguides will be large, but light, this will compensate for the heavy MDF.
So, if several european buyers show up perhaps we can gather and use this shipping method.
Transporters are happier if the cubic meter of stuff is put on a standard palette.
Stacked MDF is pretty robust, so the only fragile thing would be the waveguides, but I believe with proper packaging it should be OK. None of my stuff was damaged and there were two computers in the crates.
You can specify if your palette should be put on top of the pile or below others.
After that we'd have to find a way to ship the stuff to the other european buyers, but that's surface mail, so it will not be very expensive.
If you can get dimensions and weights I can get some quotes.
So, how much Abbey+ can you fit in a cubic meter ?...

I know that cargo by sea is pretty cheap, but you have to send a lot. Then what happens to it at the other end? Who takes it and distributes it? I've been all through this shipping distribution stuff and it is the achilles heal of making anything.
I would guess that a cubic meter would be about two dozen kits (minus drivers). Weight would be maybe 200 - 300 lbs.
You want to buy two dozen?
I haven't seen a "group buy" thing happen yet.

A group buy is usually done to get cheap prices or to get hold of objects that otherwise would be out of reach
In this case a group buy was suggested to get you started
I think that the members interested in a group buy would be mostly interested in the 15" half kit or waveguide ... but you did quite understandably ask us to be quiet about anything else than the 10" kit, not to ruin its chances ... at least thats how I understood it
I'm really interested in the 15" versions of this kit....either
15" waveguide + 15" woofer
15" waveguide + 12" woofer
18" waveguide + 15" woofer
Damn the WAF. I want the dynamics, the performance, and the sound.
Chris
p.s. I am very interested in plans for 18"-24" subs to go with the above.
p.p.s. I hope I didn't endanger any of the versions by posting my 15" preference.

Of those three the only one that will likely ever happen is the 15" + 12" woofer. The other two will have very limited appeal. I am trying to do the Abbey+ now. I need a different approach to do the waveguide as the casting method is unlikely to work very well due to the much larger size of the waveguide. A few inches is a lot more surface area.

The 10" kit is well underway with enough sold to be of interest. The 12" kit is progressing. Its the 15" that's not certain at the moment.
Gedlee,
I have not read all the postings, your pricing,
Baffle, waveguide, foam insert, mounting plate, drawings: $200
is for 1 channel only?
thanks

Thats what I am targeting, but I am reconsidering selling the baffle only as I may not be able to make enough baffles to allow for this option. Time will tell.

From your website:
"Complete kit with all necessary parts (B&C DE250, 10PS76, crossover, baffle with waveguide and foam insert, cabinet hardware, instructions): $600"
Are the crossover's assembled? What's included in "cabinet hardware"?
Thanks,
Jim

You have to assemble the crossover. Cabinet hardware is bolts, nuts, speaker terminals, sidae and back panels. Everything that you need is included.
gedlee said:
Nice. Thanks Earl! What sort of finishing work needs to be done to the back and / or side panels (i.e., will holes need to be drilled for the speaker terminals?).
Will there be an option to assemble the crossovers using our choice (brands) of parts?

As posted earlier I am interested in the 12" woofer/ 15" waveguide combination. A couple of questions;
If the wave guide has to be built in fibre glass is there a possibility of getting the waveguide without the rest of the baffle ? (would help a lot with the overseas shipping problem )
Which 12 " woofer will be used ( 12tbx100? )?
Are you up to taking preliminary orders yet or are we still in waiting stage ?
Thanks Mike Anderson

Hehe no I don't want to buy 24 of those for myself, but I'm hoping some other guys would turn up 😉
jdubs said:
You can finish them however you want. Easiest is to just paint them. Not sure yet about who drills the holes for the terminals on back.
You can throw away the crossover parts and use your own. That would be a waste however. It won't make any difference. You'd have to be very careful about matching the inductor resistances as these numbers are critical.
Michael Ando said:
The waveguide may not be fiberglass. It might be cast in polyurethane directly into the baffle. I haven't worked out the details on the 15" waveguide.
I use the 12TBX100.
I'd like to wait on the Abbey+ until I have a better idea of costs etc.
I have been waiting a long time to read reviews about the Summa.
good job guys on posting your reviews also on the Audiocircle.
Patrick Bateman, can you post your reviews also on Audiocircle?
Patrick, can you do a review on the Summa six months from now.
a long term review is better than a short term review?

I first heard the Summa in 2004. Based on reading Earl's posts on Audioasylum, I conned my girlfriend into flying out to Denver... Just to hear them. Sure, I told her it was a "vacation" but I had ulterior motives 🙂
So I am no stranger to the speaker. It is by far the biggest investment I've made in this hobby. But I'm really happy with it. Yes it's expensive, but it's a *bargain* when you consider the cost of the components, the cabinets, and the R&D effort. It's a steal at $6000.
The 15" with an 18" waveguide would likely be the "extreme" best (bestist) but its cost and size would be a real detriment. The 15" waveguide works very well and could be improved without a cost impact.
Dr Geddes ,
I just noticed this line in an earlier post. Could you say what you mean by improving the 15" guide without cost impact ? Will this happen when you get to making the 15" guides for Nathan+ ? Thanks Mike A

There is a slight axial hole on the 15", not much to worry about, but its there. The highly coherent wavefront from the waveguide meets with a perfectly circular edge and there is a small amount of diffraction. But because of the perfectly circular edge this small amount adds exactly in phase directly on axis. The cure is simple. Break up the perfectly circular mouth with some non-circular aspects. The hole will be diminished if not completely eliminated.
But its the Abbey+ that I think you mean. A Nathan+ would be a 10" woofer and a 12" waveguide. An interesting combo.

Whoops, I did mean the Abbey+. Look foward to seeing this improvement incorporated in the Abbey +. Thanks Mike A
