DML as surrounds for atmos theater?

Greetings from an interested newbie to the DIY speaker realm.

I am going to be building a sub set up to sort of match some furniture.

The rears don't have many good options as far as a match goes but if a DML could serve well as a rear surround I have some decent options. The ceiling speakers can be worked around in a few ways but DML might be pretty interesting for that application as well.

Sorry if this has been previously addressed I looked around a lot and used the search function however I didn't find any discussions on it.

Is this a stupid idea because the surround effects are supposed to be lower and DML's are going to be too "loud" when driven by the decoding Amp?

My limited general understandings would be the DML have little bass response below 150htz is that a concern with surrounds? My experience is pretty limited and involved pretty crappy surround speakers in the past. Some Polk cubes that honestly never really sounded much better than an 8 dollar RadioShack 9 volt transistor radio.

Thanks for any feedback.
