He did mention they were in the middle of a production run but didn't drop any names. That's why the 4 week wait but no problems with that though.

Oh before I forget what are you using on the bass, because 18sound is good, but not great. I think you can do better (series consisticy isn't that great)
I'm in the midst of a complete redesign and it looks likely I'll be using a pair of the AudioTech 12" geared for high efficiency but still reaching depths that 12" pro-drivers simply won't do without impractical enclosures.

I've used the 10" Flex, the bass presentation is not as tight as stiff cones. Read the review of Streophile of Rockport loudspeakers, Fremer does a good job describing the bass. For this reason Rockport is now using carbon cones on AT motors.

I have good experiences with Eton, the 12" is very good and has enough spl if you are using 2 of them per channel.

For me, Seas Excel W26/ W22, Focal Kevlar 13" are not as good as Eton. Maybe you can use the Aura sound subs, but you need a lot of them to get enough spl.

Its worth to mention from AT you can design with different cone thickness - and if you aim fore efficiency he might use a thinner cone

Be sure to know excactly what parameter you want, Per Skåning might not have the same preference as you do

But you are right, he is a very nice person

Thanks again. I had a bit of a swapping 'sesh with the bass drivers on my last project, I'm determined for that not to happen again hence the reason why I'm taking my time exploring possibilities.

Do you have any details on Eton's new 12"?

I've used the Seas W22 before and prefered an ATC 9". For me the Seas was just a tad too dry and lean, possibly more accurate in absolute sense but didn't have the same fullness and slam of the ATC. How would you describe the Etons?

The eton sounds very dynamic, big push/ kick without colouration and almost no boomy after efect. I have no specs of the new drivers, I think they have new (neodym?) motors. I would definately wait to find out.

The big AT cones have dynamics, bass detail, and drive. But it sounds not as controlled. I discussed this with Per and he agreed that due to the nature of a Poly cone you do not get the same bass as with stiff cones. I want to stress that it still sounds very good, and that is me who wants an other type of bass.

(Maybe you can buy a Per chassis and put an Eton cone on it).

As english is not my native language it's hard to express my thoughts about how everything sounds. Try to hear a Kharma/ Avalon or something else with Eton (Adam monitors).

Great to see you giving the AT a go Shin :-)
Why not use one of the 10" Scanspeak 26W aluminium or carbon-paper for bass duties? Beautiful motor and a smaller box.

I'm surprised you haven't mentioned (unless I mentioned it) using a woofer from ATC. I was thinking something like the SB75-314SC? Or perhaps they could make something a little more custom for you? You seemed so pleased with their products in your other adventures .


Also, I noticed that your pictures have exceed their bandwidth limits. I'd be happy to host them for you if you'd like.

Please don't remind me. I've looked into it and I knew it would be expensive but nearly £1600 for four 12's is waay over budget. Ideally I want to spend around £1000 at the very, very most. I even thought about cutting it down to just one each side to make the ATC's affordable.

They're nice drivers but I don't think any driver really justifies £400 a pop when you consider what's available for at least half that.

Thanks for the offer mate, unfortunately the posts with the image URL's are locked and can't be edited now so unless they're hosted on the same server they still wouldn't appear. I don't think Al or Vik would appreciate going back editing things. The bandwidth resets every month so they should be back up soonish.

Since the images have gone down, I'll repost the most upto design I did:

Click the image to open in full size.

Things have changed significantly in virtually every area though and its nothing like this now though.

Will post one of my latest in a minute.
