They used to have an option of Scanspeak tweeters on the 9s but now the new tweeter is better and cheaper many people have upgraded from the Scanspeak to the new tweeter. They have the drivers made for them, I can't remember the name of the producer. Scanspeak are expensive as Danish. To give you an idea the Scanspeak tweeters were £150 a pair, the new ones are £50.
You might better off asking on their forum, you will get more reliable direct answers there.

I've messaged Ashley James on the AVI forum and this is the reply:
"So far all fine.
Scanspeak was sold to a massive Chinese headphone company, so some engineers left and operate in Denmark in a Lab owned by SB. They designed both DM drivers but the tweeters we SB originals. Mart measured some nasties in the tweeters and they redesigned them to remove it. Now it's a standard in their OEM range.
The DM5 driver is a standard OEM modified to suit our box and for 4 Ohm Amps.
The DM10 driver was a Scanspeak design originally, but SB's Indonesian Lab used the chassis only to design the very special job we use. It costs about double the going rate for hi end OEM drivers, but it works as you know.
SB design and make speakers for Bentley. They're enormous and make 8.5 million drivers a year and 1.5 million pairs of speakers. They have a huge R & D facility and unusually make all their own cones, voice coils, spiders, rubber surrounds, metal work, chassis, everything. Very few are in their league.
They even manufacture their own special paper pulps.

John Dunlavy was criticized for using cheap off the shelf Scanspeak drivers for his best speakers, but he didn't care. The final result is what matters.
Same applies for AVI. If the result is good, then I wouldn't care who or where it's made. Obviously the work conditions at SB are not as good as Scanspeak, thus the cheaper price.

thanks for the info.. I've been reading AVI forum past few days and these speakers are either that good or some exaggerated statements are made.. I generally liked what ADM9's can do and now tempted to have a good listen to both DM5 and DM10.steve_1979 said:

ScanSpeak aren't cheap. They're some of the best and most expensive in the world. Sinar Baja bettered them by poaching Scanspeak engineers and then made further improvements with prompting from Martin Grindrod.Vladimir said:
Genelec also use Sinar Baja for their drivers too but I think they tend to use the cheaper ones. Most of what they make is price sensitive so you'd expect it. Most active speakers are built down to a price because the market is so tight. The very expensive Genelecs might be different for all I know.

It's ironic isn't it.Vladimir said:To the 'high end' crowd that spends hundreds of pounds per inch of speaker cable Dunlavy's choice of drivers felt cheap.
When you look at how cheap most speaker drivers are it seems odd that people insist on wasting money on audiophool cables costing tens of pounds per metre.

"We buy direct with Sinar Baja Electric in Indonesia. SB Acoustics Ltd is the name they give to their wholly owned distributors around the World.
All the Danish Speaker companies are Chinese now, though as SB has a lab there, so the others have sales offices.
Scanspeak have a lab there too, but are owned by an enormous Chinese headphone company that employs 10,000 and makes most of the headphones the big Germans don't.
The important point is that although drivers from the big boys like SB have been improving steadily year by year, audible distortions still exist in the crossover region because the crap from passive crossovers masks them. AVI's active crossovers have no sound at all, so they reveal driver issues that no one else has heard. We had to measure these nasties and prove to SB that they existed. Once we had, they designed special drivers for us which were clean to an octave above the crossover point.
This is how we've been able to get so close to the best headphones.

I believe you.steve_1979 said:It's an irregular shaped 17.5' x 11' room with a 10' high ceiling. It's in an old victorian house with thick brick walls so there's plenty of isolation for when I want to turn it up loud.Andrewjvt said:
I usually have them setup for near-field use at a computer desk but I've also tried them in a more conventional mid-field setup sitting about 10' away from the speakers on the other sode of the room. They have no problem fill the space.
I don't have any photos of the current DM10 system but here's an old picture of my desk when I had the DM5 speakers setup. I also have a new desk and chair which is lower than the one in the photo so that the speakers are now at the correct height.
And those aren't cuddly toys BTW.
Are dms near field monitors?

No they're really supposed to be mid-field speakers and that's how most people use them.Andrewjvt said:
I use mine in a near-field setup use because I spend a lot of time at the computer but they work equally well positioned either way IMO.
Steve, how do you feel about the orchestra being only 4 feet wide in your system?
Or rock bands fitting into a 4 foot wide stage on your system?
Plus the subwoofer being out of phase with your main speakers, especially when listening near field?
