ATC SCM20ASL WALL MOUNT (VAN HELLEN)

Postby tesilk » Sat Feb 11, 2017 8:22 am

Hi everyone,

I am new here, have one pair of ATC SCM50ASLT (connected to Naim Nac-N272 & Naim XPS2, love them) and now bought one very rare pair of ATC SCM 20ASL Wall Mount (Van Hellen).

They are connected to Cambridge Audio 851 full line of gear.

Did not find any information about it on the net, so was wondering if someone can give me some history, specs, details etc.

It's a very special 2 box wooden made blocks set of amps, speakers are large but not thick so they are supposed to be on the walls and not on stands.

They sound amazing, I love them already)

Thanks

Serge

You need to use an image hosting site like flicker or Photobucket to get an image URL that you then post on ATCForums.
Here's an old guide viewtopic.php?f=3&t=1118

Cheers

Hi Matt,

one small question.

I have a pair of SCM50ASLT, they are placed in the living room.
Room about 50 sq meters.
Distance between speakers approx 3 meters.
Distance from my sofa to speakers - 3 meters.
Distance from speakers to back wall - 1 meter
Opposite wall - 7 meters.
ATC manual says, that acoustic axis has to be 5 degrees below midrange driver.
in my case, that means I have to put my ATC towers on an additional stand of at least 20 cm.

Am I right, is it the right way to go, or it would be better just to leave it like it is now, no additional stands.

Thanks

Hi tesilk,

I think it's a matter of preference, having your ear mid way between the mid and tweeter should be fine too.

Cheers
Matt

Sorry, wasn't happy with my original post but couldn't delete it!!!



I raised my SCM 70 ASL's using pavers so that the centre of the mid dome was at ear height and preferred the result.

Felt that the midrange got even better and bass also tightened up (maybe due to less "floor bounce")

Try lowering your head 20cm as you listen and see if you like the sound better............I have a suspicion that you will.

I have an option of doing it with metal stands (specially built), very solid, 30kg, they can be put on spikes. What do you think, will it be better than pavers or wood?

Tesilk,


If it turns out that you do need/want stands then the ones in your link look pretty cool to me.

ATC uses a a pretty simple frame like design for their Classic 50's though.......( I am assuming they might also make one that suits your height requirement)

http://atcloudspeakers.co.uk/hi-fi/loud ... ies/scm50/

Maybe you could ask them directly what they recommend?

It will be interesting to see what other users here think too as there are a few different ways/materials to achieve height adjustment.

Also need to consider which method/material is best regarding the potential influence it may have on bass...........(also why I liked pavers!!)

Another reason for pavers is that the height becomes adjustable so you can really fine tune........in the end I went with 4 pavers at 4cm thick for a total lift of 16cm but listened with 2 and then 3 for a while first.

Next
