LaMa said:I have the same experience, (quality is very good with the std series and custom work is also excellent). But lead time is > 4 weeks. But they always deliver, if you are ordering at the time they are doing the drivers for Sonus then you have to wait.
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.
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.

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.

Shin:
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:
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.
An externally hosted image should be here but it was not working when we last tested it.

Heading towards something like this now:
EDIT: I was playing around with idea's and that's the one I like the most so far. It shows a dome tweeter in there which can be ignored, although I have the option to play around with swapping that middle section if the Ribbon doesn't do it for me.
EDIT2: The black bits around the drivers would be recessed and lined with felt for helping with diffraction ala. Wilson etc.

Its also now transformed into a 3.5way. The dual 12's will be side firing. This gives me a good bit of breathing room and will likely mean an end to the idea of using subs.
Driver line up:
RAAL 140-15d
2x 5" C-Quenze 15cm
2x 8" Flex Unit
2x 12" still not sure which yet though, smallish volume will be a big decider.

OK this is the absolute final design, no really! I'm now locked into nearly all the driver choices since I've made a point of ordering them to stop me from swapping
I'm giving the RAAL a go first but if it turns out I'm thoroughly dome inclined then I can swap out the tweeter and XO box as shown here:
And final driver choices are:
Treble(1.5Khz+): RAAL 140-15d
Mids(200hz-1.5Khz): 2x 5" Q-Cuenze
Bass(50hz-200hz): 2x 8" Flex Units
Sub(15-40hz): 2x Peerless XLS10
The bass drivers will roll off natural and the subs will be blended to pick up the slack.

Brings up an interesting point. From what I remember you are doing passive xo's for this one, so, what is your plan for phase alignment? From the design it isn't going to be by staggering the driver's distances from the listener, so do you plan on implementing an all-pass filter in the xo network or having asymmetrical xo slopes? Are there any more options I'm not aware of?
tinitus said:Nice .... and now your in for some serious work
edit.... well, small point ..... I think your design will benefit from a slightly slanted front on mid/woofer section ... just to make it even harder
It sounds like a small change but that would turn the project from something that was just about manageable by my skills into something that I'd have serious doubts about being able to do. Its nice to push yourself but there's already so much to account for that I just feel I'd be kidding myself if I made that change. The pretty 2d drawings are a nice indicator of overall look but they hide most of the wood working complexity. The inner wall and bracing structure for the bass-mid-sub cabinet is a little overwhelming and I'm having trouble getting my head around it, I know how I want it and the volumes needed but its a different matter arranging the panels to suit.
