i found it on the x4200 owners thread on AVF. A bit of a bodge job but a cheap way to get atmos. They do say for auro and dts x, down firing or height speakers are more ideal.

Hmm, the do-it-yourself method doesn't seem to mention a high-frequency notch filter, which I thought was necessary for the upfiring (as opposed to the ceiling-mounted and downfiiring) method to work?

Did you watch the YouTube video son of sj? It seems to be a copyright issue, hence the atmos badge if you want to sell speakers as atmos capable....

isnt a speaker a speaker at the end of the day albeit different types of course, base, tweeters etc.. What's so special about atmos speakers, are they just not the same?

All you need is speakers capable of higher frequencies, as only they reflect.

This is mentioned in the link:

Select a smallish bookshelf speaker that can easily fit on top of your front and/or rear surround speakers (choose something with similar output and frequency response capabilities above 200Hz as your other surround channels if possible).

Set your AV Receiver HPF bass management for the Atmos channels between 150-200Hz.

I said as much a couple of weeks ago.

I don't see why you need a notch filter (whatever that is). Just let the sounds that will reflect off the ceiling do so. If your receiver can cut out those that won't, do so.

I also remember a lot of people getting conned when CDs came out and people were duped into buying "digital ready " speakers which, of course, were no different to regular speakers.

More recently some Muppet tried to tell me the speakers in my Merc would have to be changed if I put a new head unit in because the existing ones "are fibre optic".
